AN - 80248725; 2285413 AB - Two herds of beef cattle were maintained beneath a +/- 500 kV direct-current transmission line during a 30-month period, and were compared with two similar herds maintained away from the transmission line. Exposures of animals under the line were five to 30 times greater than those of control animals, depending on the parameter of interest, with average exposure magnitudes of 5.6 kV/m, 4.1 nA/m2, and 13 k ions/cm3, respectively, for electric field, ion current, and density of ions. Productivity and health status of cows and calves were similar between lines and control treatments. Mean body mass of cows increased with maturity, from 438 kg in 1985 to 496 kg in 1987. Calf gain averaged 0.93 kg per head per day. No unusual sources of mortality were observed. Based on this confinement study, beef cattle permitted to graze in the vicinity of a high-voltage, direct-current transmission lines are not expected to experience any decrease in frequency of conception, calving, growth rate, or survival.

AN - 79751759; 2334871 AB - The accumulation of both activity and protein of a methyltransferase (MTase) from Aspergillus parasiticus, which catalyzes conversion of sterigmatocystin to O-methylsterigmatocystin in the aflatoxin pathway, was detected in fungal mycelia slightly before the onset of aflatoxin biosynthesis in the same cultures. MTase protein was identified in mycelial postmicrosomal (soluble protein) fractions by electrophoresis and subsequent immunoblotting using antiserum raised against purified MTase protein; MTase activity was determined by measuring the rate of conversion of sterigmatocystin to O-methylsterigmatocystin in the presence of soluble protein fractions. Using the above technique, it was determined that MTase protein as well as MTase activity increased sharply in mycelia 30 to 45 h after inoculation, shortly after which, mycelial growth rate began to decline. During the subsequent time interval (45 to 70 h after inoculation), a sharp increase in aflatoxin levels was detected in the culture medium. Results obtained from an experiment in which cycloheximide was added to cultures at various times to inhibit protein synthesis and from an experiment in which mycelial proteins were radiolabelled to identify newly synthesized proteins indicated that accumulation of MTase activity and protein in late growth phase mycelia is due to de novo protein synthesis.

AN - 79660185; 2138063 AB - The in vivo transcripts of the tobacco chloroplast gene for the beta subunit of the ATPase (atpB) were examined. In tobacco, like spinach, the atpB gene encodes multiple transcripts. Six tobacco atpB transcripts are present in vivo, with 5' ends at positions "-90", "-255", "-290", "-490", "-500" and "-610" relative to the translation initiation site. The 5' end of the atpB gene ("-610" position) is 20 base pairs from the 5' end of the rbcL gene, coded for on the complementary strand. The "-255", "-490" and "-610" regions are recognized as promoters in vitro by spinach chloroplast and E. coli RNA polymerases.

Six statistical features of the size distribution of personal income among blacks & whites in the US are reproduced: (1) the smaller median income of blacks; (2) the difference in shapes of the two distributions; (3) the % of blacks effect, ie, the greater difference between the median incomes of blacks & whites in areas with a larger % of blacks; (4) the association by area between a high ratio of median black to median white income with a small Gini concentration ratio of white income; (5) the association by area between a high ratio of median black to median white income with high white median income; & (6) the reduction of associations #4 & #5 with controls for level of development or % of blacks in an area. A feature of the behavior of individual whites toward blacks is also considered: the greater discriminatory aggressiveness of poor whites to blacks than to richer whites. There is no difference between minority & majority in the inequality process with coalitions other than coalition membership. It is suggested that the relative absence of minority victimization in more developed industrial societies as compared to less developed societies is due to the vesting of more wealth in human beings in a form that cannot be profitably taken from them: human capital. There are analogies with the classic interacting particle system model of statistical physics, the Maxwell-Boltzmann ideal gas model.

Dryland salinization is generally a result of saline water discharge associated with non- irrigated land, adversely affecting soils, vegetation and water resources, as well as creating a form of degradation which reduces the economic and aesthetic value of the land which is not easy to correct. The Soil and Conservation Service of New South Wales is oriented primarily to erosion control and the rehabilitation of eroded land, and therefore is involved in treating dryland salinity. Factors which cause saline water discharge include: vegetation, clearing, sources of salt, geology and geomorphology, soil types, climate, and land use. Salinity affects soils, vegetation, erosion and water resources. Dryland salinity requires control and prevention. The three long-term research needs of the seepage salting problem are in the areas of recharge research, water table monitoring, and model development. The Soil Conservation Service is planning a number of major programs to address the salinization problem; the expertise present in many organizations must be used in cooperative programs. Current knowledge can prevent the impending disaster, given the required level of cooperation and commitment.

Batch-culture flasks were inoculated with equal amounts of culture volume from an exponentially-growing culture and subjected to varying fluridone concentrations ranging from 0 to 100 microgram/L. Culture populations were allowed to grow without interruption for 96 hours after which populations were analyzed. Biomass, chlorophyll a and total carotenoid contents decreased with increasing concentrations. No change was observed in C-phycocyanin content. Within the lipophilic pigment fraction , decreases in the relative abundances of myxoxanthophyll, zeaxanthin, beta-carotene, and an unidentified, minor carotenoid caused corresponding increases in the relative abundance of chlorophyll a. The light-limited slope, the maximum light-saturated rate of photosynthetic oxygen evolution, and the irradiance value at onset of light saturation decreased with increasing fluridone concentration. Inhibition of growth and chlorophyll content was considered a secondary response attributable to the photo-oxidation of chlorophyll molecules. Inhibition of the photosynthetic efficiency and maximum were attributed to reduced carotenoid content. Increased knowledge concerning the effects of fluridone on bloom-forming cyanobacteria, such as Oscillatoria, may elucidate its possible algastatic utilization in aquaculture systems.

AN - 16676491; 3049749 AB - Dinitrogen fixation, an important aspect of soybean (Glycine max (L.) Merr.) production, is affected by many environmental factors. Nodulation can be altered, for example, by changes in the ratio of far-red to red (FR/R) canopy light. The influence of canopy light spectral balance on the nodulation of 'Coker 368' soybean when inoculated with different strains of Bradyrhizobium japonicum was evaluated in field and growth chamber studies. Soybean seedlings were inoculated with USDA 110 (110) or Brazil 587 (587) and grown in 10-cm diameter pipes that were filled with vermiculite and inserted at 1.0-m intervals in seedling soybean rows that were oriented north-south (N/S) or east-west (E/W) on a Norfolk loamy sand (fine-loamy, siliceous, thermic Typic Kandiudult). The FR/R ratios of canopy light (relative to the ratio in incoming sunlight, which was assigned a value of 1.00), were 1.38 for N/S- and 1.26 for E/W-oriented rows. Row orientation significantly affected nodulation when 110 was the inoculum but not when 587 was the inoculum. Nodule biomass of 110-inoculated seedlings was 48% higher with E/W than with N/S row orientation. The results show that even small changes in the FR/R ratio of canopy light can affect soybean nodulation in both field and controlled environments. They also show that this effect can be enhanced or diminished by B. japonicum strain.

AN - 16631562; 3024143 AB - Carrot (Daucus carota L.) tissue suspension cultures were subjected to 0.5-40 krad of gamma irradiation. Callus fresh weight was significantly increased and dry weight slightly increased by low doses (0.5 and 1 krad). Cell size increased at all doses. Cell number and colony-forming ability decreased. There was a negative correlation between radiation dose and mitotic index, and a positive correlation between dose and mitotic abnormalities (multipolar separations, lagging chromosomes, and bridges). Frequency of prophase was increased, and anaphase and telophase were reduced. Tissue culture conditions increased the incidence of aneuploidy and polyploidy in comparison to carrot root tips. Aneuploidy in tissue cultures was decreased and polyploidy was increased by gamma irradiation.

AN - 16497203; 2941581 AB - Some genetic damage may occur during seed storage, but the extent and effect of this damage has yet to be determined. Seed storage, by both conventional and cryogenc technologies, offers a relatively cheap method of conserving a broad range of germplasm. It will likely play an essential, complementary role, in germplasm conservation as temporary conservation until ex-situ stands are established, and as a safety measure against disastrous losses for limited numbers of seedlots. To fulfill the conservation roles, seed storage life must exceed the natural interval between germination and seed production for the next generation. Most true orthodox and many sub-orthodox seeds offer no problem, but neither recalcitrant seed class can meet this criterion with present technology. However, even short gains in viability retention of recalcitrant species can be useful (e.g., in transporting seed collections from remote areas to nurseries or laboratories).

Ten isolates of rhizobia from the Mediterranean Region were tested as one- and two-strain inocula on three cultivars of subterranean clover grown in tube culture. Two-strain inocula were 2.5% superior to one-strain inocula in increasing clover shoot weight and 2.4% superior in increasing effectiveness of N sub(2) fixation when evaluated for three cultivars. Except for root weight and the number of nodules per plant, the general effects of strains were approximately twice as important as their interaction effects.

AN - 16115526; 2670467 AB - Numerous watershed practices currently being implemented for erosion control and water augmentation purposes have improved hydrologic conditions in southwestern streams and enhanced establishment of riparian vegetation. This paper summarizes some potential opportunities for better managing existing riparian ecosystems, or for creating hydrologic regimes favoring re-establishment of new riparian communities in the southwestern United States. Generally, management opportunities exist where either the amount of water or duration of streamflow can be increased, or both. Various-sized channel structures, ranging from small gully check dams to large flood-control structures, have been used successfully for both stabilizing erodible channels and lengthening streamflow duration. These channel structures trap sediment in upstream deposits which store water and release it slowly over time, thereby producing perennial flow in previously ephemeral streams.

AN - 16114265; 2670756 AB - Investigations since 1960 on the effects of land-management practices on riparian-stream systems often have produced contradictory results. Inconsistencies have occurred, in part, because of efforts that have not been totally comprehensive and, in part, because of poor study design and procedure. This paper reviews the literature on the use of fine sediment, aquatic macroinvertebrates, and fishes as indicators for identifying and describing the effects of various land-use practices on riparian-stream systems. Also, I present the results of my research on the effects of land-management activities on these three variables for several southwestern (U.S.A.) montane streams. The integration of these two sources of information (literature and empirical data) suggests it is valid to use these three variables in detecting the effects of multiple use activities on riparian-stream systems, although other variables (e.g., solar radiation, water quality, water temperature, riparian vegetation) cannot be ignored.

AN - 16113088; 2670722 AB - Increased residential development along small mountain streams within pine forests in central Arizona has surged in the last 20 years and presents a potential threat to riparian plant communities on these small mountain streams because it can alter the nature of streamflow from perennial to ephemeral. The change in streamflow increases water stress on riparian plants along these streams. Cultural activities associated with residential development that affect streamflow are water diversions, groundwater pumping, and changes in land use. Measurements of tree densities and stand composition of Arizona alder (Alnus oblongifolia ) and box elder (Acer negundo ) showed that perennial stream reaches had greater tree densities in all diameter classes, compared with ephemeral stream reaches where small-diameter trees were absent. Xylem water-potential measurements decreased more rapidly on trees occupying ephemeral stream reaches than on trees of comparable reaches of perennial streams over time during the summer.

AN - 16110362; 2670679 AB - The delta formed by the Copper River stretches for more than 75 km along the south central coast-line of the Gulf of Alaska. It is the terminus of the outwash deposits from a large part of the most heavily glaciated region of North America, and all major rivers that flow into the delta carry extremely high levels of suspended sediments. Coastal wetlands extend inland for as much as 20 km. In 1964, an earthquake of Richter magnitude 8.4 to 8.6 raised the entire delta from 1.8 to 3.4 m above the previous mean sea level. Subtidal areas became intertidal, and intertidal areas supertidal. Marshland advanced seaward as much as 1.5 km in the intertidal zone. Vegetation on many, but not all, newly supertidal levees began to change from herbland to shrubland. A change in frequency and duration of tidal inundation and water salinity has been thought to be the most obvious cause of this succession, but explanation is lacking. Freshwater dominates the estuarine circulation due to a bar-built estuary and the extremely high input of freshwater from glacier runoff and precipitation.

Riparian plant communities in Arizona and New Mexico were examined at 153 sites and classified into 28 community types. Canonical discriminant analysis was used to examine variability of physical site characteristics both within and among community types. Elevation was the most significant factor along the first canonical axis in analyses for all community types, all riparian forest community types, and all riparian scrub community types. Both stream gradient and stream direction also correlated significantly, but on a more limited and local level. Tree population size structures and tree species distribution were studied both on sites where species were dominant and at other sites where they occurred.

AN - 16109764; 2670660 AB - Riparian communities in the southwestern United States often occur in patches and isolated pockets along stream corridors, making classifications of community types highly dependent on sampling design and methodology. We investigated the relationship between sampling intensity and species richness at five sites having differing species richness. Riparian tree species were sampled at 40 plots, each 5 x 25 m in size, at each site. Using bootstrap subsampling techniques, we determined the relationships between number of plots and tree species richness in estimating density, basal area, and species ranks. Variability in species density ranks for the most frequent species stabilized, with about 10-20 plots. As species richness increased, so did the variability associated with estimating ranks.

AN - 16108117; 2670621 AB - The structure and composition of a Louisiana swamp bordering the Mississippi River were investigated; twenty species of trees were encountered in six communities. Hackberry (Celtis laevigata ) had the highest importance value for the entire tract, followed by cypress (Taxodium distichum ), green ash (Fraxinus pennsylvanica ), and tupelo gum (Nyssa aquatica ). The under-story was sparse, and saplings were not represented in the same frequency as the trees. Herbs were monitored in 1-m super(2) quadrats to determine their frequency and density. Soil was tested for pH and for extractable nutrients, and a texture analysis was carried out. Discriminant-function analysis was performed to determine which environmental variables influence tree distribution. JF - Forest Ecology and Management AU - Devall AD - USDA For. Serv., South. For.

Ether:acetone extracts of L. fuliginosus and L. fumosus fumosus were toxic to the large milkweed bug, Oncopeltus fasciatus (L.), and in some cases caused precocious development. Profiles of compounds separated chromatographically and visualized with chromene reagents, literature reports of chromenes from L. fuliginosus , and known insecticidal/anti-hormone effects of chromenes suggest that chromenes may be responsible for the activity of some of the extracts.

AN - 16100003; 2646593 AB - In landscapes of the eastern U.S.A., deforestation and reforestation are continuing processes. To better understand these processes, we documented the change in density and size of forest islands within individual landscape types of central New York. Thirty-one 30-km super(2) sample landscapes were subdivided into 1-ha cells, and the cells were classified according to five land uses - forest, other natural vegetation, agriculture, urban, and water. Sample periods were 1938, 1959, and 1978. Using a cluster analysis, sample landscapes were grouped according to seven landscape types - urban, suburban, agricultural-urban, agriculture, transitional-urban, transitional-agriculture, and forest. The intensity of landscape use determined the frequency of fragmentation, elimination, consolidation and emergence of forest islands. The suburban landscape type had the highest rates of fragmentation, elimination, and emergence.

AN - 16097970; 2646645 AB - The reproductive processes and environmental requirements for regenerating Betula alleghaniensis, B. papyrifera, B. pendula , and B. pubescens are reviewed. Their taxonomy is confusing because somatic chromosome number varies within species, and natural hybridization is common. Paper birch and the Eurasian birches are typical species of the boreal forest, whereas yellow birch grows no farther north than 49 degree , from Manitoba and Minnesota eastward across North America, and somewhat farther south than paper birch. Birches do not tolerate shade, except that seedlings prosper best at about half of full sunlight, and can endure up to 90% shade. Long photoperiods are required for genetic sources from high latitudes and from high altitudes. Growth is optimum at about 18 degree -22 degree C soil and air temperatures. The birches do not use water efficiently and are sensitive to both drought and flooding. JF - Forest Ecology and Management AU - Perala, DA AU - Alm, A A AD - USDA Forest Serv., For. Sci.

AN - 16091475; 2652665 AB - One-year-old containerized seedlings of yellow poplar (Liriodendron tulipifera L.) were exposed to simulated acid rain (pH 3.0, 4.0, 5.5), ozone (O sub(3)) fumigation (0, 0.05, 0.1, 0.2 ppm), and drought (1, 2, or 3 one-week drying cycles) from late May until mid-October. Measurements of net photosynthesis (P sub(n)), leaf stomatal conductance (G sub(s)), and xylem water-potential ( psi sub(x)) were made on seedlings from each treatment during June, July and August. Seedlings treated with simulated acid rain at pH 3.0 showed reductions in P sub(n) (29%), G sub(s) (33%), and psi sub(x) (17%) when compared with similar seedlings treated with rain at pH 5.5. For seedlings fumigated with O sub(3), there were no significant differences in P sub(n) or G sub(s) between the controls and the other O sub(3) treatments. For seedlings subjected to drought, P sub(n) increased with increasing stress but psi sub(x) declined. Interactions involving drought and O sub(3) together had a greater impact on psi sub(x) than did either factor alone. JF - Forest Ecology and Management AU - Roberts, B R AD - Nurs. Crops Res.

AN - 16083767; 2646119 AB - Drift fences and pitfall traps captured > 2000 reptiles and amphibians during 2 years; the most common species were wood frog (Rana sylvatica ), American toad (Bufo americanus ), and red-back salamander (Plethodon cinereus ). There were differences in species abundances among streamside and upland habitats within three forest cover types: northern hardwoods, red maple, and balsam fir. Among streamside stands, fewer individuals were captured in balsam fir. The two hardwood types supported the most species. Generally, more individuals were captured in upland than in streamside habitats. Both diversity (H') and evenness (J') were correlated with litter depth, and both were higher in hardwood than in balsam fir stands. Rana sylvatica, B. americanus and P. cinereus were more abundant in hardwood than in balsam-fir stands.

The sampled area included an interfertile complex of taxa, noble fir (Abies procera Rehd.), Shasta red fir (A. magnifica var. shastensis Lemm.) and California red fir (A. magnifica A. Murr.) from north to south. Size and phenological traits were measured in a common garden test, and analyzed to investigate the pattern of geographic variation. Division of the complex into three regions accounted for essentially all the latitudinal variation and strongly indicated a stepped cline. Elevation and longitude contributed lesser amounts of source variation. Lack of fit to the regression model indicated that other local factors also were important.

AN - 15962887; 2539103 AB - Mount St. Helens provides an interesting case study of a forest and wildland area that has been radically altered in recent history. As a result of volcanic activity, the recreation environment has changed with respect to the setting, climbing opportunities, and motivations for mountaineering. An evaluation process using both qualitative and quantitative methods was developed to determine what the motivations, demographic characteristics, and preferred management techniques were for the posteruption Mount St. Helens mountain-climbing visitor. This article discusses the findings of this research in light of how resource managers might consider the issue of visitor changes in both demands and types of uses. For example, determining quota numbers based on sociological determinants (e.g., desire for solitude) need to be firmly grounded in who the visitors actually are rather than who they were. Consequently, management tools such as the Recreational Opportunity Spectrum (ROS) and Limits of Acceptable Change (LAC) may need to be altered to accommodate a changing resource or visitor base. These and other findings have implications for the future management practices of the Mount St. Helens area and other environments where the recreation resources have undergone rapid and profound change.

AN - 15940980; 2516877 AB - Four microorganisms that metabolize simmondsin (S) and related cyanogenic toxins from jojoba (Simmondsia chinensis ) were isolated by enrichment: Pseudallescheria boydii , a fungus which specifically degrades simmondsin ferulate but not S; Fusarium moniliforme ; "Flavobacterium aurantiacum "; and Pseudomonas maltophilia . The latter three organisms grow on S as a sole carbon and nitrogen source in culture media, but only F. moniliforme attacks S in the complete jojoba meal. Combinations of the four microorganisms at two temperatures, and with free air or limited air exchange for up to 20 days, were tested on jojoba meal to determine an optimum detoxification method. Degradation of toxins was most rapid and complete when Pseudallescheria boydii and Fusarium moniliforme together were incubated on jojoba meal at 25 degree C with free air exchange for 20 days.

AN - 15918782; 2500060 AB - In shaken cultures, a strain of Pseudomonas cepacia isolated from apple leaves produced pyrrolnitrin and four other phenylpyrrole antibiotics. The concentrations of these metabolites were determined at intervals for 7 days in three different media at two initial pH levels. Optical density measurements revealed maximum cell concentrations after 24 h in nutrient broth, after 48 h in King's B medium, and after 96 h in minimum salts solution. The effects caused by initiating fermentations at pH 5.8 rather than 7.0 were in most cases not dramatic, although in some instances, especially in minimum salts broth, higher concentrations of metabolites were produced with the lower initial pH. Concentrations of the phenylpyrrole antibiotics were greatly affected by choice of culture medium and incubation time.

AN - 15911393; 2505937 AB - Cell culture origin or suckling mouse brain origin viruses of Akabane disease, Aino, bovine ephemeral fever, swine vesicular disease, hog cholera, bluetongue, and minute virus of mice were each suspended in bovine serum. Aliquots (1 mL) were exposed to various doses of gamma radiation from a super(60)Co source while at -68 degree C. Aliquots (100-mL) of serum from a steer experimentally infected with foot-and-mouth disease virus were similarly irradiated. The samples were assayed for infectivity in cell culture systems before and after irradiation, and the data points were analyzed by linear regression. The irradiation doses (in megarads) necessary to inactivate one log sub(10) of viral infectivity (D sub(10)) was calculated for each virus. D sub(10) is otherwise known as the slope of the regression line. The r super(2) value, a measure of association with 1.0 = perfect fit, was also calculated for each regression line. The values (D sub(10), r super(2)) for each virus were as follows: Akabane, 0.25, 0.998; Aino, 0.35, 0.997; bovine ephemeral fever, 0.29, 0.961; swine vesicular disease, 0.50, 0.969; foot-and-mouth disease, 0.53, 0.978; hog cholera, 0.55, 0.974; bluetongue, 0.83, 0.958; and minute virus of mice, 1.07, 0.935.

AN - 15906879; 2492264 AB - The cuticles from distinct developmental stages of Ascaris suum were isolated by a combination of mechanical disruption and detergent treatment of larvae or by surgical removal of cuticle from adults. Proteins from the isolated cuticles were solubilized and analyzed by PAGE. Cuticular proteins from the third and fourth larval stages (L3 and L4) were comparable to adult, but differences in the number of bands were observed. The soluble proteins from the adult, L3 and L4 were readily degraded by bacterial collagenase, suggesting that these proteins are collagen-like structural elements of the cuticle. The data indicate the presence of a hydrophobic barrier in the cuticle of later stages of the parasite. JF - Acta Tropica AU - Fetterer, R H AU - Hill, DE AU - Urban, JF Jr AD - Helminthic Dis.

AN - 15902298; 2489891 AB - The existence of a hydrogen uptake host-regulated (Hup-hr) phenotype was established among the soybean bradyrhizobia. The Hup-hr phenotype is characterized by the expression of uptake hydrogenase activity in symbiosis with cowpea but not soybean. Uptake hydrogenase induction is not possible under free-living cultural conditions by using techniques developed for uptake hydrogenase-positive (Hup super(+)) Bradyrhizobium japonicum). Hydrogen oxidation by Hup-hr phenotype USDA 61 in cowpea symbioses was significant because hydrogen evolution from nitrogen-fixing nodules was not detected. An examination for uptake hydrogenase activity in soybean and cowpea with 123 strains diverse in origin and serology identified 16 Hup super(+) and 28 Hup-hr phenotype strains; the remainder appeared to be Hup super(-). The Hup-hr phenotype was associated with serogroups 31, 76, and 94, while strains belonging to serogroups 6, 31, 110, 122, 123, and 38/115 were Hup super(+). Hup super(+) strains of 123 serogroup typed positive with USDA 129-specific antiserum. JF - Applied and Environmental Microbiology AU - van Berkum, P AD - Nitrogen Fixation and Soybean Genet.

Based upon a study of nearly 100 yeast strains from ragi, murcha, Chinese yeast and bubod, the predominant yeasts were Saccharomycopsis fibuligera and, to a lesser extent, S. malanga . When selected yeast strains were used with various bacteria from these starters, the lao-chao rice fermentation was not satisfactory. However, when a mold (Mucor indicus ) isolated from bubod was used along with S. fibuligera , a satisfactory food was produced.

AN - 15875738; 2463296 AB - Irrigated horticulture, and particularly market garden areas located on sandy soils in the Swan Coastal Plain, Western Australia, were examined as sources of nitrates in groundwater and root zone drainage. Data were collected from lysimeter-equipped sites, and shallow (5-15 m) and deeper (20-60 m) irrigation well networks positioned to sample these areas. The NO sub(3)-N concentrations in drainage below the root zone ranged from 71 to 209 mg l super(-1) and approached potential N losses from market gardens as computed by N mass balance. Overall, the nitrate concentrations in groundwater were substantially less than potential, but still high. NO sub(3)-N concentrations in the shallow well network ranged from 9 to 79.9 mg l super(-1) with a mean of 31.2 mg l super(-1). NO sub(3)-N concentrations were similar for about one-third of the deeper irrigation wells, but were much less for most of the remaining deeper wells, ranging from 0 to 5 mg l super(-1).

AN - 15866411; 2456055 AB - Seasonal variations in numbers and biomass and breeding of 28 species of Scarabaeidae-Scarabaeinae and Geotrupidae were studied at 2 temperate sites and 2 mediterranean sites in southern France in 1978 and 1979, using cattle-dung baited pitfall traps. Maximum dung burial occurred when females were parous and ovipositing (i.e. during spring at the Mediterranean sites and summer at the temperate sites). Using biomass as a measure of dung burial the most important spring active beetles at the Mediterranean sites were: Bubas bison, B. bubalus, Scarabaeus laticollis, Onthophagus lemur and Copris hispanus , and at the temperate sites: C. lunaris, O. vacca , and O. ovatus . These results confirmed the previous choice of C. hispanus, C. lunaris, B. bison and O. vacca for introduction into Australia. In addition it is suggested that B. bubalus, S. laticollis and O. lemur be considered for introduction into Mediterranean areas of south western Australia to complement those species already introduced for bush fly control.

AN - 15855904; 2456139 AB - Nine different isolates of the bacterium Bacillus coagulans were isolated from honey bee larval cadavers collected from colonies afflicted with half-moon disorder (HMD) in New Zealand. One isolate was selected for detailed characterization and pathogenicity testing. Laboratory-reared larvae became infected when inoculated with the test isolate at 1 or 2 of age. No infection was observed among larvae inoculated in combs placed in small colonies in outdoor cages. Although able to infect larvae under certain conditions, B. coagulans is probably not the cause of HMD.

AN - 15853492; 2450023 AB - Six isonitrogenous, isocaloric diets containing soybean meal as replacement for animal protein, were fed to juvenile Penaeus vannamei . Shrimp fed the three lowest dietary levels of soybean meal had similar weight gains. Weight gains declined significantly as the dietary soybean levels increased. Protein and fat gains followed the pattern of weight gains. Survival rates obtained for various treatments ranged from 86.7 to 98.3%. However, these differences could not be attributed to the dietary levels of soybean meal. Dry matter feed intakes were not significantly different. Pellet water stability was inversely related to level of dietary soybean meal. Feed conversion, protein efficiency ratio and apparent protein utilization were similar for diets having 0 to 56% soybean meal. There were no significant differences in whole body composition of lipid, ash, calcium or potassium of shrimp on the various diets. Body phosphorus percentage decreased significantly when soybean meal levels exceeded 42%. The 70% soybean meal diet was utilized very poorly by the shrimp.

This insect also is a pest of numerous fruits and vegetables. We have established the European parasite Peristenus digoneutis Loan in northern New Jersey, and it has spread downwind into two additional counties, one of which is in New York State. Average total parasitism of tarnished plant but nymphs in 1987-1988 was 36% in the first generation and 29% in the second, each about three times the normal rate of parasitism by native parasites.

All five species were exposed to treatments (temperature and photoperiod) for 24 h and then held at 25 degree C for progeny development. Mean parasitoid emergence for the five species in descending order was Muscidifurax raptor Girault & Saunders (46%), Pachycrepoideus vindemiae Rondani (37%), M. zaraptor Kogan & Legner (26%), Urolepis rufipes Ashmead (14%), and Spalangia nigroaenea Curtis (< 1%). Length of photophase (6, 12, or 18 h) did not significantly effect parasitoid emergence for any species. Effects on fly eclosion, sex ratios, and parasitoid-induced mortality for the five species are reported along with possible reasons for low S. nigroaenea emergence.

The hypothesis that restricted creep feeding primes an intestinal allergic reaction to starter diet ingested after weaning was tested. Histologic examination of intestine from control pigs and principals that survived for 6 days after infection did not reveal any substantial morphologic difference between creep-fed and not creep-fed groups. In conclusion, creep feeding was not required for the production of diarrhea in this model. Creep feeding did not induce morphologic changes characteristic of an allergic reaction in the small intestine.

AN - 15849738; 2437162 AB - Female Caribbean fruit flies, Anastrepha suspensa (Loew), eclosed before males in field-collected and laboratory-reared samples. This dimorphism is due to more rapid female development during pupal, larval, and perhaps even egg stages. Adult females in the laboratory stock and in the field-collected samples eclosed before male members of the same cohort. At the conclusion of pupal development, 92% of females and only 52% of males emerged from the pupal state on the first of two days of eclosion. During the early portion of the larval maturation period, sex ratios were biased toward females and biased toward males at the end (r super(2) = 0.73). Within 72 h of oviposition, 70% of female flies and only 55% of male flies had hatched. Earlier adult female eclosion does not necessarily result in earlier sexual maturation.

The major oriental fruit fly hosts were wild strawberry guava, Psidium cattleianum Sabine, and common guava, Psidium guajava L., outside the crop area; the major melon fly host were cultivated truck crops on farms. Abundance of oriental fruit fly and melon fly throughout five major habitats (upland guava shrub, lowland guava shrub, java plum forest, ironwood forest, and farms) was associated with oriental fruit fly abundance in guava areas and melon fly abundance on farms, respectively. During periods of peak guava abundance, numbers of oriental fruit fly increased on farms; during period of peak crop production, melon fly increase in habitat surrounding farms.

AN - 15846650; 2447021 AB - The mortality of Aedes aegypti (L.) larvae treated with Bacillus thuringiensis var. israelensis was reduced by tannic acid at concentrations as low as 0.25 mM (425 mg/liter). The LC sub(50)'s for B. thuringiensis var. israelensis treatments were 45 ng/ml in deionized water and 233 ng/ml in 1.5 mM tannic acid. Soaking the bacteria in tannic acid for 48 h before the exposure of test insects resulted in a lower LC sub(50) value of 140 ng/ml and steeper log-probit regression slope. Although tannic acid lowers the gut pH of A. aegypti larvae, it is evident from the retention of B. thuringiensis var. israelensis toxicity after gut acidification in solutions of citric, hydrochloric, and phosphoric acid that this change did not mitigate the toxin's activity. The presence of tannins in mosquito breeding sites may require higher application rates for B. thuringiensis var. israelensis when used by mosquito abatement personnel as a larvicide.

Such bobbing, with the proboscis contacting the fruit surface at each bob, always preceded probing and puncturing of the fruit with the ovipositor. Forty-eight percent of 25 females tested probed within 5 min; 11 of these laid an average of 29 eggs per oviposition bout, which lasted an average 20.5 min. Withdrawal of the ovipositor was followed by ovipositor grooming and extensive continuous sponging of the fruit surface with the proboscis. During observations of female papaya fruit flies on fruit in a commercial papaya planting, all of these types of behavior were observed.

A polynomial regression showed that egg development across temperatures was nonlinear ranging from 10 d at 31.7 degree C to 19 d at 20.6 degree C. Instar development for both sexes was similar at each temperature, and development was linear. At all temperatures, third instars required the least time for development and fifth instars required the most. Males, both single and paired, outlived females at all temperature regimens. At 20.6 degree C, single males lived a maximum 286 d and paired males 289 d; corresponding female cohorts lived a maximum 167 d and 140 d, respectively.

Ten species in six genera are represented in this guild of mites. Thelytoky was confirmed experimentally by rearing the offspring of virgin females for six species that represented 99% of the individuals collected. The two rarest species are arrhenotokous. Long developmental times and low hatching success were characteristic of the most abundant parthenogen, but other thelytokous species have relatively short generation times, high reproductive outputs, and high hatching success rates.

AN - 15840751; 2435816 AB - A variety of factors were investigated to determine their influence on the epizootiology of the nuclear polyhedrosis virus (NPV) of the gypsy moth, Lymantria dispar L. Egg masses laid on tree boles had substantially higher levels of contamination than those laid on rocks, ground debris, or understory brush. Egg masses laid on different tree species showed no differences except that those on black oaks were less contaminated at one of the three research sites. Egg mass contamination was not related to date of collection, compass orientation, or number of larvae hatched from the egg mass. Larvae collected from pitch pine had higher infection rates than those from either white or black oaks; however, the differences were not substantial. Mortality rates of larvae collected from different host species were even less distinctive. The implications for epizootiology and sampling are discussed.

AN - 15839172; 2436200 AB - Intraspecific intrinsic variation in foraging behavior is a common but often overlooked feature of parasitoids. These variations result from adaptations to the variety of foraging circumstances encountered by individuals of the species. We discuss the importance of understanding the mechanisms governing these intrinsic variations and the development of technologies to manage them. Three major sources of variation in foraging behavior are identified. One source for variation is genotypically fixed differences among individuals that are adapted for different foraging environments. Another source of foraging variation is the phenotypic plasticity that allows individuals to make ongoing modifications of behavior through learning, which suits them for different host-habitat situations. A third factor in determining variation in foraging behavior is the parasitoid's physiological state relative to other needs, such as food and mating. A conceptual model is presented for comprehensively examining the respective roles of these variables and their interactive net effect on foraging behavior.

AN - 15836808; 2439668 AB - Effects of host and nonhost substrates on probing and preoviposition activity were monitored for adult summerform pear pyslla, Cacopsylla pyricola Foerster. Tendency to initiate probing activity during a 15-min observation period was similar on a susceptible pear (Pyrus communis L. "Bartlett"), a presumed nonsusceptible pear (P. calleryana Decne.), and apple, but was reduced on quince. Depriving pear psylla access to pear for 4-6 h or 14-16 h before the observation period increased the percentage of psylla that probed during the observation period; effects of host deprivation on tendency to probe were independent of substrate. Tendency to initiate probing on P. communis was greater on lower leaf surfaces than upper leaf surfaces, which may suggest that probing is initiated in response to cues received at the leaf surface.

AN - 15834470; 2439196 AB - The foraging territory size of Heterotermes aureus (Snyder) was investigated on the Santa Rita Experimental Range south of Tucson, Ariz. A comparison of three techniques for delineating territorial boundaries suggested that the release and recapture of dyed termites and agonistic behavior among termites were the most reliable techniques, whereas spatial and temporal patterns of termite attack on baits were unreliable for determining boundaries. Data obtained with the first two techniques indicated that many territories encompassed an area of several hundred to a few thousand square meters. These data contrasted sharply with those obtained from spatial and temporal patterns of termite attach, which provided an estimate of 13.9 m super(2) for average territory size.

The assemblage of coccinellids consisted of six species: Hippodamia convergens Guerin-Meneville, H. tredecimpunctata tibialis (Say), H. parenthesis (Say), Coleomegilla maculata (DeGeer), Coccinella transversoguttata Faldermann, and Cycloneda munda (Say). H. convergens was the most abundant coccinellid, followed by H. tredecimpunctata, H. parenthesis, Coleomegilla maculata, Coccinella transversoguttata , and Cycloneda munda in rank order of abundance. Seasonal patterns of population increase differed among species. At all sites, populations of each species fluctuated unpredictably among years and independently of populations of other species. Assemblage structure at a site changed unpredictably from year to year, but the extent of change was constrained.

Body weight and body weight gain were depressed by all toxin treatments, but the effect of AF and T-2 toxin in combination was less than additive. Liver and kidney weights, as a percentage of body weight, were increased by AF treatment, and heart weight, as a percentage of body weight, was increased by T-2 treatment. Treatment with T-2 toxin induced necrotizing contact dermatitis on the snout, buccal commissures, and prepuce. Consumption of AF resulted in increased serum activities of alkaline phosphatase, aspartate transaminase, cholinesterase, and gamma -glutamyltransferase, and decreased serum concentrations of urea nitrogen, cholesterol, albumin, total protein, calcium, potassium, magnesium, and phosphorous.

AN - 15824271; 2424741 AB - Maintenance of species and within-species diversity is a goal of the USDA Forest Service, Pacific Southwest Region, which is examining and monitoring the genetic effects of silvicultural activities using isozyme analysis in conjunction with traditional methods. An effective monitoring and evaluation program will help improve silvicultural practices. Regional policies on gene conservation focus mainly on artificial regeneration. Tree improvement, nursery, and reforestation activities in the PSW Region may significantly affect adaptability, genetic diversity, and economic timber traits. The Base-Level Tree Improvement Program (TIP) aims for: (1) high adaptability via use of native species and local wild seed; (2) high within-species genetic diversity via designs for sampling several local seed-stands and via long-term plans for improvement using simple recurrent selection and bulking among the see-production-area plantations; and (3) moderate improvement in performance via mild selection for superior phenotypes.

The temperature of the liquid stream to which the vapor is flowing (the absorbing liquid) is that required to bring its calculated equilibrium vapor pressure to that of the calculated equilibrium vapor pressure of the evaporating liquid stream. We suspect this is a generally true phenomenon if the process is carried out close enough to conditions of actual equilibrium between the vapor and liquid phases.

AN - 15813660; 2411692 AB - Sex pheromone production was terminated in mated Heliothis virescens (F.) females, and the titer of the pheromone in the pheromone gland reached a very low level within 2 h following mating. Mated females did not call and were nonreceptive to males following mating. However, mated females resumed pheromone production and became receptive on nights following the night of mating. Mating with backcross sterile males (obtained by backcrossing female hybrid progeny of H. virescens and H. subflexa (Guenee) cross to H. virescens males) also caused termination of pheromone production and receptivity.

AN - 15812781; 2398816 AB - We studied the ecological impacts of a polygyne fire ant invasion on ants and other surface-active arthropods at a field station in central Texas. Arthropod abundance and species richness were assessed using a combination of baits, pitfall traps, and litter samples. This invasion decimated the indigenous ant fauna. Competitive replacement appears to be the primary mechanism behind this effect. Species richness of ants in infested areas dropped by 70%, while the total number of native individuals dropped by 90%. Of 35 species of ants collected in this study, 23 were either significantly less common or absent from infested sites. The abundance of isopods, erythraeid mites, and tumblebug scarabs declined significantly, while the abundance of ground crickets, a brachypterous roach, and a symbiotic scarab increased significantly. Overall, the species richness of non-ant arthropods was 30% lower in infested sites, and individual numbers were 75% lower.

AN - 15811093; 2411816 AB - Anaphes diana (Girault) (= Patasson lameerei Debauche), a mymarid egg parasite of Sitona spp., was introduced from Europe beginning in 1976 and is now tentatively established in the United States. Techniques are described for the separation of eggs of Sitona spp. from soil, using a series of fine-mesh sieves, water, and a saturated salt solution. Data from 9 years of sampling in an alfalfa field at Newark, Del. (> 19,300 host eggs extracted), showed that the mean peak density of viable overwintering eggs of Sitona hispidulus (F.) was 14.6 per 100 cm super(3) of 1 cm deep surface soil. At the study site, Sitona) egg densities consistently increased during the fall as a result of oviposition, peaked during January and February and decreased during the spring as a result of egg hatch. Although the incidence of parasitism by A. diana remained surprisingly low (0.29%), the fact that the species was recovered during 3 years and up to 7 years the last release, indicates that it has colonized at the Delaware release site.

Our goal was to screen strains and media to obtain pullulan in maximal yield, purity, and stability. Pullulan yields and properties were strongly affected by strain specificity, but a single medium performed best with most strains. Sucrose was the preferred carbohydrate for all five strains. A "color variant" strain of Aureobasidium , NRRL Y-12974, possibly representing a distinct species, produced a polysaccharide of intermediate molecular weight which was stable during storage at 4 degree C, heating to 100 degree C, and high shearing action. This polysaccharide was 70% pullulanase sensitive and contained the least contaminating melanin pigment.

AN - 15805991; 2397083 AB - The occurrence of polygyne and monogyne Solenopsis invicta (Buren) populations offers a unique opportunity to test hypotheses related to nestmate recognition. Recognition bioassays were based on the aggressive behavior observed during intraspecific introductions of monogyne and polygyne S. invicta workers (intruders) into polygyne and monogyne S. invicta colonies (residents) and interspecific introductions into Solenopsis richteri Forel colonies. No aggression differences were observed between monogyne and polygyne colony workers that were removed from their colonies, then reintroduced into their parent colony (no aggressive behavior) or when S. richteri workers were introduced into monogyne or polygyne colonies (strong aggressive behavior). In all other cases, polygyne workers displayed significantly less aggressive behavior than monogyne workers, as residents and as intruders. At the species level, polygyne workers are less able to distinguish nestmates from nonnestmates than monogyne workers. This result fits a theoretical prediction of diminished intraspecific aggression in polygyne populations.

Preincubation at 25 degree C of desalted crude extracts from darkened leaves resulted in the time-dependent increase in activation state that was inhibited by P sub(i) (IC sub(50) (concentration causing 50% inhibition) approximately equals 3 mM), molybdate, okadaic acid (IC sub(50) approximately equals 25 nM) and vanadate, but was stimulated by fluoride. The "spontaneous activation" of SPS in vitro was enhanced slightly by exogenous MgCl sub(2) (up to 5 mM) and exhibited a pH optimum of 7.0 to 7.5. Radioactive phosphate incorporated into SPS during labeling of excised leaves with ( super(32)P)P sub(i) in the dark was lost with time when extracts were incubated at 25 degree C.

AN - 15798821; 2406887 AB - The immunoglobulin response of chickens to colonization by Campylobacter jejuni isolates B-540 and Clin-1 was monitored. Chicken humoral IgG and biliary secretory IgA (sIgA) responses were assessed by enzyme-linked immunosorbent assay (ELISA). In the colonized chickens, humoral IgG activities were highest at hatch, dropped to their lowest level after 2 weeks, and increased by 8 weeks to levels similar to those detected at hatch. The sIgA activity was lowest at hatch and increased by 4 weeks in colonized chickens while remaining lower in the control chickens. Chickens colonized with isolate B-540 showed a primary sIgA response during the first 4 weeks and reached a plateau over the final 4 weeks. In spite of these limited humoral and secretory immunoglobulin responses, once the chicken ceca was colonized by C. jejuni the organism persisted throughout the 8-week experiment.

AN - 15797461; 2392085 AB - Substrate inhibition in batch fermentations can be avoided by employing the fed-batch technique in which substrate concentration is kept at low levels by a programmed feed rate. This research demonstrates the use of a heat-flux sensor to control substrate addition by continuously monitoring evolving heat which is proportional to fermentation rate. Batch fermentation with 240 g/L glucose in the medium was compared with a fed-batch starting with 20 g/L glucose in the medium and increased, with 500 g/L glucose, to a final equivalent glucose concentration of 240 g/L. The batch fermentation produced 106 g/L ethanol in 39 hr at 2.72 g/L/h, while the best fed-batch produced 114 g/L ethanol in 34 hr at 3.35 g/L/h with the same nutrients.

Cecal colonization by C. jejuni was compared after the organism was exposed either to phosphate-buffered saline, normal rabbit serum, rabbit hyperimmune anti-C. jejuni serum, or anti-C. jejuni antibodies extracted from chicken bile. The colonization dose-50% was increased by twofold to 160-fold when the organism was preincubated with hyperimmune antiserum or the bile antibodies as compared with preincubation with phosphate-buffered saline.

AN - 15792104; 2407039 AB - The resistance to cecal colonization by Campylobacter jejuni was assessed by challenging three crossbred stocks of commercially available broiler chickens. These three stocks, designated A, B, and C, were related as follows: Offspring from four pedigree grandparent flocks were used as progenitors. Stock B was derived by cross-breeding grandparent I with grandparent 3. Stocks A and C were crossbreeds from grandparents 1 and 2 and grandparents 3 and 4, respectively. Campylobacter jejuni were gavaged into 48-hour-old chicks, using the same levels of challenge dose for each of the different chicken stocks. Six days post-challenge, the birds were sacrificed, and cecal contents were plated onto Campylobacter -selective media. Results from two replicate trials with three isolates of C. jejuni indicated that chicken stock A was colonized in only two of 60 ceca, stock B in six of 60, and stock C in 19 of 60 chicken ceca.

Bragg, California area by 1976, through the combined action of the defoliating cinnabar moth (Tyria jacobaeae ) and a root feeding flea beetle (Longitarsus jacobaeae ). In 1987, 4 previously infested Ft. Bragg sites (3 sites where control had been documented and another unstudied site) were examined. Senecio jacobaea densities at these sites were 0.0, 0.0, 0.01 and 0.18 plants/m super(2), indicating both continued and improved control of the weed. The flea beetle and the cinnabar moth both persist at the sites, despite very low numbers of S. jacobaea) plants. The control of S. jacobaea has resulted in the return of near natural vegetation at the 2 coastal prairie sites and regained productivity at the 2 pasture sites.

Outer membrane protein (OMP) extracts of these organisms were prepared and studied by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and Western blot analyses. No consistent differences between the colonizer and noncolonizer were detected by SDS-PAGE. By Western blot analysis with rabbit anti-OMP serum. After affinity purification and cross absorption of serum against OMP from the colonizer, an antigen of 69 kD molecular weight was found unique to the colonizing strain. Exclusive association of the 69 kD antigen with the colonizing strain suggests that it may be a colonization factor.

AN - 15781374; 2381985 AB - A method of inducing Pasteurella haemolytica serotype 1 (Ph1) lung infection in goats, using low numbers of bacteria and without impairing host immunity, was developed. Two trials were conducted. Results of trial 1, using 10 principals (Ph1 agar beads) and 6 controls (agar beads alone), indicated that Ph1 organisms imbedded in agar beads could survive host lung defenses for 32 days. Results of trial 2 indicated that lung immunity in the inoculated goats (principals) was high and they were more protected than controls against a transthoracic challenge of Ph1 (1.18 x 10 super(7) colony-forming units) injected into a lung of each goat on posttreatment day 35. The serum Ph1 indirect hemagglutination antibody titers in the principals of both trials increased, compared with titers in controls. Principal goats in trial 2 had higher Ph1 indirect hemagglutination antibody titers after injection of Ph1-impregnated agar beads and less severe lung lesions after challenge exposure than did controls.

AN - 15780591; 2394487 AB - In the setting of goals for biological diversity we must address specific, achievable objectives for the principal elements of concern in an area. Those goals must be integrated in three major ways. First, they must be integrated into overall conservation plans of public-resource management agencies and private-sector organizations which collectively determine ecological conditions and trends in the area. Obviously, those plans must also be coordinated among the agencies, and the needs of people must be taken into consideration. Second, goals and actions must be integrated up and down geographic scales so that actions taken at individual sites or stands contribute to goals for watershed conditions, which are in turn part of a regional landscape that sustains both the variety of life and meets human resource needs. And third, goals and actions must integrate across the biological spectrum of genetic resources, species, communities, ecosystems, and biomes.

AN - 15771373; 2384006 AB - Understanding the cycling of ammonia between croplands and the atmosphere is of importance to agriculturalists and atmospheric scientists. Flux densities of gaseous ammonia (NH sub(3)), particulate ammonium NH sub(4) super(+)), and total ammoniacal nitrogen (AN) were measured using an aerodynamic method above an alfalfa (Medicago sativa), L.) canopy between April and July 1981 at a rural location in central New York State. In air not influenced by local sources, NH sub(3) and NH sub(4) super(+) averaged 1.5 and 3.0 ppb, respectively, at 1 m above the crop. Ambient NH sub(4) super(+) varied consistently with synoptic air masses being lowest (2.3 ppb) for NW and highest (6.4 ppb) for SW flows. Concentrations and gradients of both species were higher during periods of hay harvest. JF - Atmospheric Environment AU - Dabney, S M AU - Bouldin AD - USDA-ARS Natl. Sediment. Lab., P.O.

AN - 15761354; 2373787 AB - A study was conducted to determine whether subcomponent proteins (previously identified as BCSP20, BCSP31, and BCSP45, and the corresponding recombinant proteins rBCSP20, rBCSP31, and rBCSP45) that were recovered from the cell surface of Brucella abortus strain 19 were immunogenic and protective for mice when compared with Brucella cell surface protein (BCSP) and with a proteinase K-treated lipopolysaccharide (PKLPS) extracted from B. abortus strain 2308. Protection was evaluated after challenge exposure with a virulent culture of B. abortus strain 2308, using CS-1 or BALB/c mice or both inoculated with vaccines of various combinations and concentrations, with and without PKLPS or BCSP. Protection was assessed by enumeration of splenic colony-forming units, reduced mean splenic weight relative to controls, and the relative serologic response (immune response) in an ELISA. The general results indicate that BCSP, PKLPS, BCSP20, and BCSP31 are immunogenic or protective or both.

AN - 15759561; 2374024 AB - Newly hatched chickens were treated with the trichothecene mycotoxin, T-2 toxin, during the first day of life. Control chickens were treated with other agents known to cause immunosuppression. Chickens were infected on day 6 (5 days after treatment with T-2 toxin) by intraperitoneal inoculation with Salmonella typhimurium . Blood samples were collected from treated chickens (noninfected) and used to assess the responsiveness of blood lymphocytes to T-cell or B-cell mitogens, phytohemagglutinin, or lipopolysaccharide, respectively. The T-2 toxin had a profound negative effect on the ability of the chickens to resist salmonellosis, as measured by survival. The toxin effect in reducing phytohemagglutinin- and lypopolysaccharide-stimulated mitogenesis, though significant, was not severe. Our data indicate a direct effect of T-2 toxin on native resistance to systemic salmonellosis. JF - American Journal of Veterinary Research AU - Ziprin, R L AU - Elissalde, M H AD - USDA, Agric. Res.

AN - 15747193; 2361099 AB - Laboratory-reared adults of the tachinid parasitoid, Archytas marmoratus Townsend, were released and evaluated against larvae of Heliothis zea (Boddie) in whorl stage corn during 1986-1988. Resulting rates of parasitism by A. marmoratus on H. zea larvae occurring at 0.3, 0.5, and 1.0 per row-m were 58.3, 44.2, and 52.8%, respectively, when about 340 females/ha were released, and 45.9, 38.2, and 32.1%, respectively, when about 160 females/ha were released. In both studies, no significant differences in rates of parasitism were found between host densities. The number of H. zea larvae parasitized by A. marmoratus increased linearly over the range of host densities studied. This suggests the per capita mortality is density-independent and, therefore, should not increase or decrease as host density is varied within the range of early season populations.

I. Chukar Partridge. AN - 15742520; 2357377 AB - Chukar partridges were fed diets containing 1.25, 2.5, or 5 ppm aflatoxin; 1, 2, or 4 ppm ochratoxin A (OA); or 4, 8, or 16 ppm T-2 toxin. Toxin-induced mortality was seen during the third week with 4 ppm OA (12.5%) and 16 ppm T-2 toxin (15%), compared with the mortality in control chukars fed no toxin (2.5%). Body weights were significantly decreased by the highest level of aflatoxin at 3 weeks of age, by the highest level of OA by 2 weeks of age, and by 8 and 16 ppm T-2 toxin by 1 week of age. Aflatoxin did not affect liver weight and OA did not increase kidney weight in 3-week-old chukars. There was a slight decrease in kidney weight in chukars fed 4 ppm OA: however, the decrease was related to the decrease in body weight produced by the toxin. Mouth lesions were seen at all levels of T-2 toxin fed. JF - Avian Diseases AU - Ruff, MD AU - Huff, W E AU - Wilkins, G C AD - Livest. and Poult. Sci. Inst., Beltsville Agric. Res. Cent., Agric.

Heretofore no generally accessible, computerized compendium has been available to provide access to the vast and dispersed body of knowledge on these organisms. The computerized North American Immigrant Arthropod Database (NAIAD) was developed to provide such a single source. This interactive data base contains 51 fields of core data on the 1,800 species of arthropods known to be immigrant to America north of Mexico. The COBOL program and data files reside on a Wang VS-100 minicomputer at Beltsville, Md., and the data files are accessible from remote locations via TTY (ADAS). Extensive hard copy, back-up files also are maintained. The NAIAD program and its use are described here, and the data fields included in the program are discussed.

Acute exposure to 6 mu g of CPA/ml of modified Krebs-Henseleit solution significantly decreased 5 in vitro turkey cardiac muscle performance criteria: maximal weight a muscle could lift; maximal contraction velocity; relaxation velocity; time to peak contraction; and total time for muscle contraction and relaxation. The effect on these 5 criteria appeared to result from intracellular changes partially associated with calcium availability and were irreversible, suggesting that physiologic changes had developed after acute exposure to CPA.

The larval stages of the flies are highly integrated myrmecophiles, despite their also being obligate predators of the ant brood. Both immature and adult forms of the ants contain the same hydrocarbon components, but in stage-specific proportions. M. piperi larvae possess cuticular hydrocarbon components identical to those of their host ants, and have no other discernible hydrocarbon components. The percentage composition of the hydrocarbons from larval M. piperi closely mimics that of larval C. modoc . In contrast, adult M. piperi have many cuticular hydrocarbon components that are not found on the ants; these flies are immediately attacked by the ants if they are discovered in the nest.

AN - 15719580; 2341845 AB - This article provides philosophical background for development of a computerized North American Immigrant arthropod Data base (NAIAD). A species might be regarded as immigrant only if it passes all tests for an organism that cannot be considered native. However, for increased flexibility for NAIAD, we considered a species as immigrant if it cannot clearly be shown to be native. Thus, an immigrant arthropod is a resident or possibly resident species that either definitely is not native or might not be native.

AN - 15717890; 2332854 AB - Distribution of pear psylla eggs on pear seedlings and cues affecting oviposition were monitored. Most eggs were deposited on the youngest foliage; few eggs were placed on the oldest, leathery leaves. Highest densities occurred adjacent to the midvein or in leaf serrations. Densities were very low on the leaf blade away from the midvein. Oviposition was induced in areas normally avoided (e.g., leaf blade) by providing strips of tape as artificial structures resembling midveins. Masking of particularly prominent midveins with strips of tape resulted in reduction of oviposition in these normally preferred sites. These results suggest that the midvein provided positive mechanical cues to ovipositing females. Effects of egg location on survival and development of eggs was quantified. Survival rates of eggs were higher for eggs deposited along the midvein than those deposited on the leaf blade. Survival decreased with increasing plant water stress.

AN - 15716212; 2334270 AB - The white-rot basidiomycete Lentinula (syn. Lentinus) edodes (Berk.) Pegler is the dominant edible mushroom cultivated on wood. The major xylanase detected in cultures grown on a commercial oak wood medium was extracted, purified, and characterized. The enzyme was a non-debranching endo- beta -D-xylanase (1,4- beta -D-xylan xylanohydrolase; E.C.3.2.1.8) highly specific for xylans, with a molecular weight of 41,000 (on sodium dodecyl sulfate gels) and an isoelectric point of 3.6. With aspen glucuronoxylan as substrate, the enzyme showed optimal activity at pH 4.5-5.0 and 60 degree C, with a K sub(m) of 0.66 mg/ml and specific activity of 310 units/mg protein at 40 degree C. It was capable of hydrolyzing (forming reducing sugars from) 40%-50% of the hydrolyzable linkages in either glucuronoxylan or arabinoxylan. The enzyme produced xylose and major identifiable products in the xylobiose or xylotriose (and presumably larger) size range.

AN - 15715718; 2337454 AB - To characterize the behavior of codling moth, Cydia pomonella (L.), males to sex pheromone sources, we determined the lapsed time for response, number responding, and number of attempted pseudocopulations directed to pheromone placed at various heights in or near apple trees. The time for and number of responses was similar at any height as long as the pheromone source was within and not outside the tree's canopy. Responses to pheromone and captures of moths were significantly lower for pheromone sources or traps outside the tree canopy, whether above, below or between trees. The maximum numerical response was at the 3.0-m level, 1.0-1.5 m from the top of the tree. In an unsprayed apple orchard, the number of moths caught in traps at 3.5 m was not significantly different from the number caught at 1.5 m, but in a sprayed orchard, the number caught at 3.5 m was significantly higher than at 1.5 m in six of 10 biweekly comparisons.

AN - 15713910; 2332301 AB - The duration of feeding and relative amounts consumed by Hessian fly, Mayetiola destructor (Say), larvae on resistant and susceptible seedling wheat plants labeled with ( super(35)S)L-methionine was investigated. Plants were labeled over 48-h periods from initial infestation to 8 d after infestation, and the uptake of super(35)S by larvae determined. With the H sub(3) and H sub(5) genes for resistance, the uptake of super(35)S by larvae was significantly less than on susceptible controls, and suggested that the larvae were unable to initiate or maintain sustained feeding on the resistant plants. With the H sub(6) gene for resistance, uptake of super(35)S by larvae during the first 48 h was not significantly different from that on susceptible controls, but then declined between 48 and 96 h. These data indicate that with the H sub(6) gene, larvae fed actively for the first 48 h after infesting the plants, then ceased their feeding between 48 and 96 h. All larvae on resistant plants were alive 48 h after infesting plants and approximately 60% were alive 96 h after infesting resistant plants.

We tested the hypothesis that C. parasitica infection stresses the tree and predisposes it to attack by the twolined chestnut borer, Agrilus bilineatus (Weber). Scarlet oaks with obvious disease symptoms attracted significantly more A. bilineatus , cerambycids, and scolytids than did apparently healthy trees. However, only 9 of 21 diseased trees were successfully colonized. Total nitrogen and tannin concentrations of the phloem did not differ significantly between diseased and control trees; however, phenolic concentrations were significantly higher in the phloem of diseased trees that were colonized by borers. Total carbohydrate concentrations of xylem and phloem in July did not differ significantly between diseased and control trees, even in those diseased trees that were colonized.

Several aspects of its population dynamics were investigated in the insectary and field at Temple, Tex., because of its potential value in a biological control program. Females deposited about 750 eggs, and a generation was completed in about 45 d in an insectary at natural temperature and photoperiod. Insectary populations increased 1.12 times per day and doubled every 6.3 d. In the field, larvae eclose from egg masses presumably deposited in crevices under mesquite bark, feed nocturnally on the leaves, and pupate in the soil. Weather conditions and parasitism of larvae and pupae were important factors regulating populations of M. indomita . The potential effectiveness of M. indomita as a biological control agent of mesquite was also examined. It was concluded that M. indomita would be only a partially effective agent because the defoliating activity of the larvae does not permanently damage mesquite.

In this study, the use of appropriate unparasitized control hosts allowed the authors to apply Abbott's formula to estimate total parasitoid-induced mortality. Gypsy moth, Lymantria dispar (L.), larvae at the age of 0, 3, 6, or 9 d were stung by the solitary endoparasitoid, Cotesia melanoscela (Ratzeburg). There were significant curvilinear relationships between host age at the time it was stung and parasitoid emergence and parasitoid-induced nonemergence mortality. Emergence rates were lowest and parasitoid-induced nonemergence mortality rates were highest among hosts stung on days 0 and 9. The negative effect of parasitism on growth rates was greatest among hosts stung on days 6 and 9, and parasitoid development time was longest within hosts stung on days 0 and 9.

Moths in five families (Lasiocampidae, Noctuidae, Notodontidae, Pyralidae, and Sphingidae) harbored N. guyanense . Twenty-five species of Noctuidae were infected. Multiple species of Spodoptera and Mocis served as hosts for N. guyanense . The most commonly infected hosts were Lesmone formularis Huebner, S. dolichos (F.), S. frugiperda (J.E. Smith), and Xanthopastis timais (Cramer). Lepidoptera in 19 families, including 121 species of Noctuidae, did not harbor N. guyanense . Also, arthropods in 12 orders and 70 families of non-lepidopteran insects, 2 orders of Arachnida, and 5 families of Araneae were not infected by N. guyanense .

Salmonella typhimurium and Salmonella choleraesuis var kunzendorf were labeled specifically by the peroxidase-antiperoxidase technique in paraffin-embedded tissues of infected swine for conventional light microscopy and by postembedding immunogold labeling on ultrathin sections for electron microscopy. Salmonella typhimurium had a low tendency to invade the enteric mucosa and did not reveal any predilection for a specific intestinal location. Salmonella choleraesuis var kunzendorf , however, was located preferentially in colon and on the luminal surface of ileal M cells of Peyer patches and had a tendency to invade the enteric mucosa there.

AN - 15673024; 2306100 AB - BEEAMATE is a computer model that simulates the genetic composition of a honeybee (Apis mellifera L.) colony, and determines the number of individuals carrying particular combinations of alleles at any time (t). Determination of a colony's genetic composition is made as a function of the genotype of the queen and the drones with which she mates. BEEAMATE is constructed to be a module to a larger honey bee colony population model (BEEPOP). Population size is predicted by the BEEPOP model, and is divided into subpopulations with different genotypes by BEEAMATE. Simulations were conducted to determine the number of brood cycles needed to change the genetic composition of a colony depending upon the time of year during which the queen is introduced, weather conditions, and the size and genetic composition of the initial colony population.

AN - 15660501; 2303366 AB - The effects of disturbance type on seedling environment and establishment of alpine species with different physiological and life history traits were examined during a 2-yr study on the Beartooth Plateau in southwestern Montana, USA. Both disturbance characteristics and species life history and physiological traits affected seedling establishment. Pretreatment soil properties of the two disturbance types had the greatest effects on soil temperatures and nutrients and, consequently, on seedling growth and survival. Soil surface characteristics had the largest effects on seedling emergence; surface stabilization was essential for holding both soil and seed in place. Single species responses varied in magnitude but were similar on both disturbance types. In general, there were larger differences among species in emergence and growth than in survival. Thus, successful seedling establishment on different alpine disturbance types may depend more on obtained the necessary conditions for seedling emergence and on species interactions than on the ability of seedlings to survive different environmental conditions.

AN - 15656591; 2302613 AB - Based on 46 data sets, this paper documents standing dead trees as a proportion of total basal area and density of forest stands in the Northeast. Stands were grouped into six forest cover types ranging from coastal oak and pine types to montane spruce and fir. Over the wide diversity of stand histories, species, and sites studied, the proportion of dead trees was 3-42% of total basal area and 5-36% of total density. Montane spruce-fir stands characteristically had high proportions of standing dead trees, expressed as basal area and density. By quantifying the proportion of dead trees occurring in forests of the Northeast, this study provides a reference for evaluating overall forest vigor or decline. JF - BULL. TORREY BOT. CLUB.

AN - 15656461; 2298893 AB - Reproductive capacity and activity patterns of native screwworm (Cochliomyia hominivoras (Coquerel)) males were evaluated by release and recapture of sterile females in central Belize. On six occasions 4,000 virgin, 1-d-old sterile females were released at a central location. A total of 382 sterile females and 66 native females were recaptured on sentinel sheep at four locations. Ratios of virgin to mated recaptured females were used to calculate an estimated number of matings per release. These data and estimates suggest that although screwworm males have relatively low population densities, they have significant excess mating capacity, and that production and release of competitive sterile males is important for the success of the screwworm eradication program.

AN - 15653250; 2300720 AB - The influence of competition, exploitation and level of energy input on toxicant fate and effect in simple aquatic laboratory ecosystems was studied. Twenty-four systems composed of populations of guppies (Poecilia reticulata ), snails (family Planorbidae) and various taxa of algae were maintained in 40-liter flow-through glass aquaria. Ecosystems were established in which guppies and snails were sympatric and allopatric. The systems were exposed to three levels of guppy exploitation and received two levels of energy input. Shifts in system structure followed chronic exposure to a sublethal concentration of dieldrin. System responses to the toxicant ranged from increased population biomass to population extinction and were influenced by level of exploitation, energy input rate and species competition. Both toxicant effect and fate were influenced by system organization and environment.

AN - 15650619; 2295651 AB - Net aboveground primary production (NPP) at 725 m in elevation in the colorado forest of the Luqillo Mountains of Puerto Rico averaged 7.60 t/ha yr on two 0.4-ha permanent plots and was determined by summing aboveground biomass accrual (0.59 t/ha yr), litterfall (6.80 t/ha yr), and herbivory (0.21 t/ha yr). The total leaf area index (trees, epiphytes, and ground vegetation) was 4.95 m super(2)/m super(2), the aboveground woody volume and biomass, 220 m super(3)/ha and 130 t/ha, respectively, and standing herbivory and the herbivory rate, 5.1 and 4.0 percent/yr, respectively. Over a 600-m elevational gradient in the Luquillo Mountains, the number of trees per hectare, basal area, and soil organic matter increased with elevation; whereas, the specific leaf area, canopy height, range of tree diameters, forest volume and biomass, leaf area index and species richness declined. Ingrowth and mortality of trees, tree growth (diameter, volume, and biomass growth), litterfall, loose litter, standing herbivory and herbivory rates, litter turnover, aboveground woody NPP, and total NPP all declined with an increase in aboveground elevation.

Three observers independently spot mapped one 42-ha plot (Markwood) in mixed-conifer forest, and four others independently spot mapped another (Teakettle). All observers analyzed all maps. Consistency among analysts and observers in estimating the numbers of territories of breeding species on each plot was generally poor. Across all combinations of analysts and maps, 71% of all ANOVAs had significant analyst and/or observer effects. Observer effects were generally greater than analyst effects. When observers analyzed their own species maps, CVs of individual species ranged from 0% to 173% (mean 41%) at Markwood and from 0% to 188% (mean 60%) at Teakettle.

AN - 15639796; 2287871 AB - Alaska-cedar, Chamaecyparis nootkatensis (D. Don) Spach, has been dying in undisturbed forests throughout southeast Alaska for the last 100 years. To determine if decline spreads, boundaries of mortality at seven sites with decline were mapped using aerial photographs taken in 1927, 1948, 1965, and 1976. Mortality was present at all seven sites in 1927. The boundaries of mortality have since expanded, but not by more than 100 m beyond the 1927 limit. In ground surveys, dead Alaska-cedar trees, classified according to their degree of deterioration, were recorded in 427 plots along 39 transects. Fifty five taxa of understory vegetation were also recorded from 280 plots along these 21 transects; an ordination was produced from their distribution that represented a gradient from bogs to sites with better drainage. Most mortality was associated with bog and semibog sites. Alaska-cedar has a disproportionate level of mortality (65% of basal area dead) relative to other conifers. Although decline is relatively species specific and has patterns of local spread, the spread of mortality is along a specific, preexisting ecological gradient. These results, and the apparent lack of any site to site spread in the last 100 years, suggest that Alaska-cedar decline is not caused by some biotic agent. JF - CAN. J. BOT./J. CAN. BOT.

AN - 15632417; 2274497 AB - Spatial autocorrelation analysis was applied to natural populations of monoecious Splachnum ampullaceum and dioecious S. sphaericum from Isle Royale, Michigan. Male and female gametophores of both species are highly clumped, resulting in locally biased sex ratios. In our study populations, ratios were typically biased 2:1 in favor of females. Directed dispersal of spores, which could produce such patterns, is rejected as an explanation for significant spatial autocorrelation because the unique spore dispersal mechanism of Splachnum ensures that both sexes will be dispersed to any given point. Moreover, in S. ampullaceum , protenema from single spores have the ability to produce either male or female shoots. In experimental cultures of S. ampullaceum, S. sphaericum , and S. rubrum , low light, pH, and mutrition favored production of males over females. Therefore, preferential production of male or female gametophores in appropriate microhabitats may be responsible for the clumping of the sexes observed in natural populations.

AN - 15631244; 2280466 AB - Nectar characteristics of six onion (Allium cepa L.) cultivars were examined to assess the potential for preferential foraging by honey bees (Apis mellifera L.) Mean nectar amounts for six cultivars ranged from 0.54 to 0.84 mu l per floret per day. Onion cultivars differ in flowering potential, with cultivars varying from 176 to 359 flowers per umbel and 32 to 74 umbels per 30 onion plants. All cultivars examined contained highly concentrated nectar with total dissolved solids ranging from 52 to 65%. Onion nectar was analyzed by gas chromatography to determine qualitative sugar differences among onion cultivars. All cultivars were hexose-dominant, having sucrose ranges from 4.0 to 14.4% and nearly equal amounts of fructose and glucose. There were significant differences in sugar content between the onion cultivars. Nectar composition and honey bee visitation among the six test cultivars were compared. It was determined that honey bees foraged preferentially on some of the onion cultivars. JF - Environmental Entomology AU - Hagler, J R AU - Cohen, A C AU - Loper, G M AD - Honey Bee and Biol.

AN - 15630743; 2280984 AB - Distribution of pear psylla, Cacopsylla pyricola (Foerster), eggs on dormant and developing pear budwood was quantified for field and laboratory material. Most eggs were deposited in the grooves just beneath buds, particularly beneath the terminal bud. Preference changed seasonally, and subterminal buds became increasingly preferred as shoots became more phenologically advanced. On the more advanced shoots psylla laid eggs extensively on newly flushed tissue. Egg survival was affected by location on the shoot, with eggs deposited directly on buds having higher rates of mortality than those deposited adjacent to buds or in lenticels (30-50% versus 18-25% mortality). Development rates of eggs were not noticeably affected by location of eggs on shoots. Evidence indicates that psylla "wait" for phenologically more advanced shoots before reproductive activity is fully engaged. JF - Environmental Entomology AU - Horton AD - Yakima Agric. Res.

AN - 15630466; 2283677 AB - A non-pest population of Colorado potato beetle, Leptinotarsa decemlineata (Say), was monitored in the field and in the laboratory to define some cultural and host plant factors that might prompt increased use of potato by a population locally adapted to a wild host species (Solanum sarrachoides Sendt.). This study tested whether elimination of the beetle's natural host from plots of potato would result in increased densities of beetles on potato, and examined whether beetles showed differences in performance on and in preference for S. sarrachoides or potato. In 2 years of study, egg densities on potato were higher in weed-free than weedy plots; paired preference tests in the laboratory also indicated that beetles deposited the most egg masses (92%) on S. sarrachoides . Densities of larvae and adults on potato were not affected by weed density. JF - Canadian Entomologist AU - Hornton AU - Capinera, J L AD - Yakima Agric. Res. Lab., USDA-ARS, 3706 W.

AN - 15620754; 2265429 AB - Ambulatory dispersal behavior of Neoseiulus fallacis (Garman) was studied in the laboratory to evaluate within-plant movement in relation to temperature and prey density. Adult female N. fallacis were confined in 2.5-cm-diameter arenas on the abaxial surface of excised corn leaves. Four temperatures (23, 28, 33, and 39 degree C) and prey densities ranging from 0 to 55 spider mite eggs per cm super(2) were used. The walking paths of these mites were traced, digitized and used to calculate turning angles, walking speeds and turning rates. A computer simulation of walking behavior used this information to model mite ambulatory behavior and predict dispersal rates. Neoseiulus fallacis) behavior while on whole corn leaves was quantified to verify the results of the simulation. The results showed that N. fallacis will follow a leaf or arena edge (edge-walking) at all temperatures and prey densities.

AN - 15619410; 2263968 AB - The weight of Potamogeton gramineus L. winter buds was greatest between 6 and 10 cm deep in the sediment for samples collected from two northern California irrigation canals. The relationship between winter bud weight and depth was adequately described by a polynomial equation containing a quadratic term, but coefficients in equations were different for two canals. For buds planted at various depths, after 10 weeks growth measurements in terms of plant dry weight, shoot length, rhizome length, number of flowers, ramets, leaves, and floating leaves per plant were all negatively related to planting depth. Plants growing from greater depths had lower rates of shoot elongation, leaf production, and ramet production. Allocation of biomass to photosynthetic tissues and flowers was also influenced by initial planting depth, as was the time of emergence from the sediment.

AN - 15593423; 2253127 AB - Colostrum-deprived lambs and CF1 mice were vaccinated with water-in-oil emulsion vaccines containing nonviable whole cells (WC) of Corynebacterium pseudotuberculosis with and without muramyl dipeptide (MDP). Efficacy of vaccines was determined from the survival of mice and lesions in lambs after IV injection of 10 super(4) colony-forming units of C. pseudotuberculosis). In mice, protection was related to the concentration of WC in the vaccine. In lambs, high prechallenge antibody titers (geometric mean titers from 5.1 to 5.4 by day 35) were observed after vaccination with WC. Protection and vaccination site abscesses in lambs were related to the concentration of WC and MDP.

AN - 15579285; 2229879 AB - This report of damage by red imported fire ants (RIFA) to highways in North Carolina and Florida further emphasizes their pestiferous nature. Depressions or potholes (2.5-15 cm deep and up to 1.4 m long and 45 cm wide), adjacent to RIFA mounds, were observed in three highways in Onslow Co., NC (CDR. Roger Grothaus, U.S. Naval Medical Field Laboratory, Camp Lejeune, NC--personal communication). Investigation by one of the authors (CTA) revealed that removal of soil from beneath the roadway by RIFA caused the road to collapse under vehicular traffic. The larger depressions were hazardous to vehicles and all caused sufficient breakup of the asphalt surface to require repairs.

AN - 15493907; 2217823 AB - A simple and rapid method for the isolation of high-molecular-weight DNA from insects is described. The method does not require CsCl ultracentrifugation or extensive dialysis. High-molecular-weight DNA was obtained within 24 h. Since the entire insect was used for DNA isolation, an initial nuclei-enriched fraction was required. Genomic DNA was extracted from lysed nuclei by organic phase separation (liquid/liquid extraction). This method has been successfully applied to the isolation and purification of DNA from eight different adult insects (Heliothis zea, Musca autumnalis, M. domestica, Blatta orientalis, Tenebrio molitor, Lymantria dispar, Ostrinia nubilalis , and Manduca sexta ).

AN - 15450784; 2183871 AB - A starch formulation of Bacillus thuringiensis Berliner is being developed as a component in a pest management system to control Ostrinia nubilalis (Huebner). Palatability is one property of starch formulations which must be investigated; this study was done to identify materials that will cause O. nubilalis larvae to feed readily on starch granules. The best feeding responses were to mixtures containing lipid, sugar, and protein. Coax was the most effective material tried. In greenhouse tests, phagostimulants increased the effectiveness of granules containing B. thuringiensis for killing O. nubilalis larvae. For example, when Coax was added to the granules, the amount of B. thuringiensis used could be reduced by 75% without reducing mortality.

AN - 15448256; 2179395 AB - Pecan, Carya illinoensis (Wangenh.) K. Koch, orchards provide an important habitat for the red imported fire ant, Solenopsis invicta Buren, and orchards from middle to southern Georgia were heavily infested. Honeydew produced by blackmargined aphids, Monellia caryella (Fitch), on pecans was an important source of carbohydrate food for S. invicta , which were found foraging at 9-m heights in trees. Mowing of orchard ground cover caused a change in the ratio of S. invicta on the ground to that in trees but was not correlated with outbreaks of M. caryella in trees. S. invicta was a major predator of eggs, larvae, and pupae of a green lacewing, Chrysoperla rufilabris (Burmeister), and of the pupae of Allograpta obliqua (Say) in pecans but had little effect on the eggs of Hippodamia convergens Guerin-Meneville. A close mutualistic relationship between S. invicta and the mealybug Dysmicoccus morrisoni (Hollinger) was discovered.

AN - 15435583; 2171882 AB - The eye lens is a useful tissue for studying phenomena related to aging since it can be separated into differentially aged or matured zones. This work establishes correlations between ubiquitin-lens protein conjugating capabilities and age, as well as the stage of maturation of bovine lens tissue. When exogenous super(125)I-ubiquitin was combined with supernatants of epithelial (least mature), cortex, and core (most mature) tissue, ATP-dependent conjugation of super(125)I-ubiquitin to lens proteins was most effective with the epithelial tissue preparation. Conjugate formation was greatest when lenses were obtained from young animals.

The drains (10 cm diameter corrugated and perforated polyethylene tubes) were 1 m deep and were spaced at 10, 20 or 30 m intervals. The atrazine and metolachlor in runoff were analysed using gas chromatography and electron capture and Hall Electrolytic conductivity detection. Drain spacing had no effect on herbicide concentrations in the runoff. Both herbicides underwent a rapid reduction in concentration for the first 34 days after application. Concentrations of the herbicides were significantly higher (65 and 60 per cent for atrazine and metolachlor respectively) from plots without subsurface drains for the first runoff event. After this the presence of absence of subsurface drains had no significant effect on herbicide concentrations in the runoff. There was over twice as much runoff from plots without subsurface drains. The reduction in runoff losses from subsurface-drained plots was not offset by an increase in leaching losses from these plots.

AN - 79488913; 2629201 AB - Toxin produced by Pasteurella multocida type D was investigated for its effect on serum complement and serum biochemistry in rats. Rats were given a sublethal single subcutaneous injection of D toxin equivalent to 0.2 microgram/kg of body weight. Serum obtained 1, 3, 5 and 7 days post-treatment was tested for complement activity, total bilirubin, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP). Serum complement titers were significantly elevated (P less than 0.05) at all times after injection of toxin compared to rats injected with diluent and tested at the same intervals. Bilirubin was decreased but both control and D toxin-treated rats had low concentrations of bilirubin in their sera. The other biochemical constituents measured had no consistent pattern that would indicate liver damage in the rats.

In developed countries, where considerable resources have been devoted to controlling the problem, there is still serious concern that much needs to be done. To aid in planning for land use it is important that the potential erosion hazard of an area be assessed. Empirical models have been developed for erosion prediction but because their nature cannot safely be extrapolated from their countries of origin. The Universal Soil Loss Equation (USLE) is the best known of these models. It includes all those factors that determine the magnitude of sheet and rill erosion and these include rainfall, soil, topographic, crop management and soil conservation factors. The rainfall utilized in the USLE is the product of the total energy of a rainstorm and the storm 's maximum 30 minute intensity. To calculate this index requires long term records (20 yrs) on a continuous recording basis for individual storms. Simpler indices need to be tested or developed for wider application in developing countries. In the broader view, agro-climatic analyses need to be undertaken to allow assessment of the development of the protective canopy of various crops throughout their growth. Factors to consider are the likely chance of success of particular crops and the timing of cultivation and development of cover. Provision of data should first concentrate on providing answers to immediate problems or on providing ' best approximations ' where actual data cannot be provided. The data set required for assessing rainfall erosion hazard has much in common with that required for applications in agricultural production and water resources. In developing networks, care must be taken to prevent uncoordinated action that may result in a less effective network.

AN - 79475395; 2623630 AB - A congenital deformity condition called crooked calf disease, of widespread occurrence in western North America, is known to be induced by maternal ingestion during gestation of certain members of the Lupinus genus containing the quinolizidine alkaloid teratogen anagyrine. Because some piperidine alkaloids from other sources induce a similar condition, we have investigated the alkaloid composition and teratogenicity of Lupinus formosus, reported by others to be low in quinolizidines but rich in the type of piperidine alkaloids that we have speculated would be teratogenic. GC/MS analysis of L. formosus showed seven major and nine minor components in the total alkaloid fraction. All seven major and five of the nine minor components, representing all but 3% of the fraction, were identified by mass spectrometric fragmentation patterns and GC retention times. They included several potentially teratogenic piperidine alkaloids (including a very large amount of ammodendrine), as well as several nonteratogenic quinolizidine alkaloids plus a trace (at nonteratogenic levels) of the known quinolizidine teratogen anagyrine. The plant induced severe crooked calf disease with limb, spinal, and palate involvement in experimental calves. The deformities are believed to have been induced by ammodendrine.

AN - 79441685; 2515134 AB - Heated sugar/amino acid reaction mixtures, known to contain products that are clastogenic and/or mutagenic to cells in vitro, were evaluated for clastogenic activity in mouse bone marrow using the erythrocyte micronucleus assay. Heated (i.e. browned) fructose/lysine reaction mixtures were also evaluated in the Salmonella his-reversion assay and the Chinese hamster ovary (CHO) cell chromosomal aberration assay to confirm and extend previous in vitro observations. Significant mutagenicity of fructose/lysine mixtures was observed in Salmonella typhimurium strains TA100, TA2637, TA98 and TA102, with greater activity in mixtures heated at pH 10 than at pH 7. S-9 decreased the activity in strains TA100, TA2637 and TA98, but increased the activity in strain TA102. Both pH 7 and pH 10 reaction mixtures of the fructose/lysine browning reaction were highly clastogenic in CHO cells. Heated mixtures of fructose and lysine, and of glucose or ribose with lysine, histidine, tryptophan or cysteine, did not increase the frequency of micronucleated erythrocytes in mice when administered by the oral route. This indicates the absence of chromosomal aberrations in erythrocyte precursor cells, and indicates that the genotoxic components of the browned mixtures are not absorbed and distributed to bone marrow cells in amounts sufficient to induce micronuclei when given orally. Because sugar/amino acid browning reactions occur commonly in heated foods, it is important to evaluate further the in vivo genotoxicity of browning products in cell populations other than bone marrow.

AN - 79397822; 2600665 AB - The effects on the pancreas of chronic (95 wk) dietary exposure to protease inhibitors from soy and potato were compared in rats and mice. Soy and potato trypsin inhibitor (TI) concentrates were prepared from defatted raw soy flour and potato juice, respectively, by selective precipitation and ultrafiltration. Animals were fed a diet in which casein supplied approximately 20% protein. Each concentrate (less than 1% of the diet) was added to provide 100 and 200 mg of trypsin inhibitor activity per 100 g of diet. In short-term (28 d) experiments in rats, both sources of TI decreased the apparent nutritional quality of casein and produced pancreatic hypertrophy consistent with a hormonally mediated feedback mechanism for pancreatic adaptation to diet that is interactive with the nutritional status of the animal. After long-term feeding (95 wk), soy and potato TI produced dose-related pancreatic pathology in rats consisting of nodular hyperplasia and acinar adenoma, which was typical of that associated with raw soy flour. Although mice responded similarly to rats to soy TI in short-term (28-d) feeding experiments, they were resistant to the formation of these lesions following long-term feeding. This considerable species variation in propensity to develop preneoplastic and neoplastic lesions of the pancreas is not predicted by the short-term hypertrophic and hyperplastic response of the pancreas to TI.

AN - 79307159; 2813445 AB - Logistic and biologic aspects of three separate means of administration of cyclopamine for experimental induction of terata or embryonic death in sheep were examined. Oral capsule administration of crystalline cyclopamine is logistically simple and biologically effective, but costly in terms of amount of compound required. Embryos were affected in five of seven ewes dosed cyclopamine orally at higher levels (four nonpregnant and one with cyclopia). Intramuscular administration of cyclopamine dissolved in ethanol was logistically simple but without biologic effect at levels tested. Three of three treated ewes had normal offspring. Osmotic minipump administration of powdered cyclopamine suspended in propylene glycol was logistically unsatisfactory with serious delivery complications. Osmotic minipump administration of cyclopamine dissolved in ethanol was logistically very satisfactory, and one ewe among three treated animals was nonpregnant at term. There were no nonpregnant ewes nor deformed offspring in 17 controls. JF - Proceedings of the Society for Experimental Biology and Medicine.

The data collected for the NRI during the period 1982 to 1987 generally consists of land cover and use, erosion data, land treatment, and other factors. The greatest changes on the nation 's 1.9 billion acres of nonfederal land occurred on grazed land and developed land. 8.3 million acres of grazed land was converted to cropland. Developed land increased by 4 million acres with most of the development occurring in the Sun Belt. Sheet and rill erosion rates decreased in the 1980 's probably as a result of conservation practices. Nationwide, a total of 2.88 billion tons of soil are lost annually with more than half occurring on cropland. Wind erosion rates on cropland increased slightly during the five year period probably as the result of the droughty years during the 1980 's in the Great Plains. The majority of prime farmland is used for cropland. Prime farmland decreased by 1.4 million acres due to land development and to a classification change for some acres because of the loss of irrigation water.

AN - 79269968; 2804949 AB - Mice were given T-2 toxin daily by stomach tube for a period of 10 days. Three mice were killed on days 1, 2, 7, 9, and 12, and selected tissues were processed for electron microscopy and analyzed for cellular abnormalities. No changes in cellular ultrastructure were observed in either kidney or pancreas. Necrosis of a few cells (estimated as 0.1%) and an occasional slight reduction of brush border microvilli were observed in the intestinal mucosal epithelium at 1 and 2 days post treatment but not at 7, 9, and 12 days post treatment. The most significant changes were observed in the liver and included aberrant forms of endoplasmic reticulum. The liver changes were, however, transitory in that they maximized at 1 and 2 days post treatment and then subsided so that by 7 days post treatment the tissues appeared almost normal. The liver changes induced by T-2 were similar to those induced by aflatoxin as observed in a previous study.

Of the approximately 1 million acres in this drainage area, 87.5% are cropland, 10% are woodland, and the remaining acres are pastureland and various urban land uses. Approximately 55% of the croplands ' erosion rates are < 5 tons/acre/year. That leaves 400,000 acres of cropland eroding at rates in excess of 5 tons/acre/year. 1300 landowners install conservation practices on 160,000 acres annually, reducing erosion by 750,000 tons. At this rate all of the cropland will be treated within 5 years. Since erosion control programs have been on-going for many years , there should be dramatic reductions seen in sediment rates. Erosion control programs need to be targeted to the most critical subwatersheds in order to achieve significant reductions in sediment delivery. An effective sediment reduction program must include both a sediment trapping element, as well as an erosion reduction element. Some suggestions for future land treatment programs in the Peoria Lake Basin are: (1) Concentrate soil conservation efforts in the watershed areas above the surrounding Peoria Lakes; (2) Actively encourage and promote the adoption of cropping systems which reduce tillage and increase crop residues; (3) In priority watersheds, employ large sediment basins and man-made wetlands to trap sediment before it reaches the Lake; (4) Utilize a coordinated, multi-county approach to target efforts at the most critical sites; (5) Erosion control on some steeper cropland adjacent to streams and near the lake can only be achieved economically by removing that land from production and establishing permanent cover; and (6) Organize citizen-based steering committees in each subwater shed to develop an action plan specific to each subwatershed.

AN - 79451323; 2515439 AB - Recent work on the aflatoxin biosynthetic pathway is reviewed, with special emphasis on the enzymes of the late stages of the pathway involving conversion of sterigmatocystin (ST) to aflatoxin B1 (AFB1) through an O-methylsterigmatocystin intermediate. Two enzyme activities were discovered in subcellular fractions of cell-free extracts of a mutant strain of Aspergillus parasiticus (SRRC 163): 1) A post-microsomal methyltransferase (MT) catalyzed conversion of ST to OMST, and 2) a microsomal-associated activity (oxido-reductase) converted OMST to AFB1. The 168 KDa, anionic MT was purified to homogeneity and characterized (two subunits, 110 KDa and 58 KDa). Preliminary evidence indicated the presence of a cationic isozyme of the MT in mycelial extracts. The oxido-reductase has been partially purified and characterized. Polyclonal antibodies were prepared to the anionic MT and the enzyme's amino acid composition determined. A cDNA library has been constructed from mRNA isolated from Aspergillus parasiticus mycelia during the onset of AFB1 biosynthesis for the purpose of identifying the genes responsible for aflatoxin biosynthesis.

AN - 79450636; 2482445 AB - Gliotoxin, a mycotoxin with antimicrobial and immunosuppressive capabilities, is produced by several genera of fungi including the pathogenic fungus Aspergillus fumigatus. The ability of selected isolates of A. fumigatus to produce gliotoxin on three different media was tested and a thin layer chromatographic and high performance liquid chromatographic method for quantitation of gliotoxin from rice culture was developed and is described. Rice cultures were extracted with chloroform and the resulting extract was partially purified by precipitation with petroleum ether and cleanup by gel permeation chromatography. Gliotoxin was detected by thin layer chromatography and quantitated by high performance liquid chromatography using a U.V. absorbance detector with a 254 nm filter and a mobile phase of methanol-water 43:57 (V/V) with a flow rate of 2.0 ml/min. The retention time for gliotoxin was approximately 4.8 min. From rice samples spiked with gliotoxin concentrations of 0.67, 1.33, 2.67, 4.00 and 5.33 micrograms/g the average recovery was 83.8%.

AN - 79450325; 2515437 AB - Non-aflatoxin-producing isolates of Aspergillus flavus from nature and isolates of A. flavus that had lost their toxigenic trait following laboratory transfer were compared biochemically. After the addition of aflatoxin B1 precursors sterigmatocystin or O-methylsterigmatocystin to whole cell cultures, the non-toxin producing isolates from nature remained non-toxigenic while toxigenicity was restored in the non-toxigenic laboratory strains. Results imply a lack of enzymes needed for biochemical conversions of precursors to aflatoxin B1 in natural non-producers and suppression of these enzymes in the non-producing laboratory strains.

AN - 79449914; 2615790 AB - Nivalenol is a toxic trichothecene metabolite which is produced by a number of different Fusarium species. However, the nature of its immediate biosynthetic precursor is not known. Oxidation of 7-deoxynivalenol(3 alpha,4 beta,15-trihydroxy-12,13- epoxytrichothec-9-ene-8-one) to nivalenol occurred with reagents known to react by a free radical pathway, such as hydrogen peroxide-ferrous ion-ascorbic acid or lead tetracetate, but not with electrophilic reagents requiring prior formation of the enol. These results suggest that 7-deoxynivalenol or an acetylated derivative could be the biosynthetic precursor of nivalenol.

AN - 79299012; 2813253 AB - The purpose of this study was to determine whether 2-thiobarbituric acid (TBA) values could be used to predict microbiological spoilage of poultry meat. The TBA values of control and inoculated (cultured breast skin microflora, 10(5) cells/mL) chicken breast and leg meat were examined at 0, 2, 7, and 14 days storage in slightly adverse storage conditions (6 C) and at 26 and 20 days, respectively, when spoilage occurred (10(8) cfu/g). Psychrotrophic counts were also obtained on these sampling days for control and inoculated breast and leg meat. Microbiological counts were significantly different for control and inoculated samples on each of the sampling days. However, no significant differences between TBA values of control and inoculated samples were noted on any of the sampling days. No difference was observed between the TBA value of the inoculated product, which had reached spoilage levels (10(8) cfu/g), and the control product, which was not spoiled (less than 10(7) cfu/g). Therefore, the TBA test is not an accurate predictor of microbiological spoilage of poultry meat.

The history of federal policy toward wetlands and agriculture reflects such changing public perceptions of wetlands. The Food Security Act of 1985 contained a swampbuster provision that makes a farm operator who plants an annual crop on converted wetlands, ineligible for various payments, loans and insurance coverage otherwise available to a farm under the act. The success of the swampbuster provision in slowing agricultural conversion of wetlands requires depends upon many complex factors, such as the amount of wetland suitable for conversion and the dependance upon farm program benefits of a farm operation with land subject to wetland conversion. The ability of the swampbuster provision to limit wetland conversion is greatly circumscribed by these conditions. Creation of a wetland reserve may be a more effective method for ensuring wetland conservation. Such a reserve could be generated by two methods: (1) expansion of currently existing programs to purchase fee title, permanent easements of limited-term leases on agricultural wetlands; or (2) through a wetland restoration program to restore converted wetlands that are currently used for cropland. The potential costs of such programs for creation 2.5, 5 and 10 million-acre wetland reserves are given. To evaluate a proposed wetland reserve, both the direct and indirect benefits of as well as its costs must be examined. Many of the potential costs and benefits of a wetland reserve program are poorly understood, such as its role in reducing crop price support payments or the monetary equivalent of the social benefits of wetlands. Additional efforts by federal, state and local governments and private organizations will be needed if the national goal of a ' no-net-loss ' of wetlands policy is to be achieved.

Statistical power regression analyses were performed on 19 sets of published data on size and laboratory permeability of unconsolidated sediments. The exponent of grain diameter ranged from 1.11 to 2.05, but most values were significantly less than 2.0. Results indicate that the permeability/grain size relation alternatively may be expressed, from an empirical basis, as k = cd to the 1.65 to 1.85 power. Values of c and the exponent both generally decrease with the decreased textural maturity and increased induration. From the data acquired a generalized graphical functional relation of grain size and permeability was prepared and the permeability of a texturally mature sediment was estimated using regression equations with slopes higher than 1.75, and that of a texturally immature sediment using regression lines with lower slopes. Using maturity criteria and data from the literature, fields of permeability for grain sizes of dune, beach, and river sediments were indicated.

The Food Security Act of 1985 contained several measures which have had a direct impact on water quality. For example, the retirement of highly erodible land from production and encouragement of the creation of filter strips around lakes and streams greatly reduced the delivery of sediment and nutrients to freshwater systems. Water quality promises to be a major theme in the development of legislation to succeed the Food Security Act of 1985. Several new proposals have been offered to incorporate water quality concerns directly into farm legislation. Wellhead protection programs would restrict land use, input use and tillage practices on cropland that overlies potentially vulnerable groundwater supplies. Wellbuster programs would restrict the federal farm program benefits going to farmers whose practices increase the chance of agricultural chemicals leaching into groundwater supplies. Making both penalties and positive incentives relating to water quality responsive to market conditions would help to ensure that these incentives interact cooperatively. Programs directed at water quality must account for the interactions with other agricultural policies. Conservation title programs should be consistent with commodity programs and provide appropriate economic co-incentives to elicit environmentally sound production practices. The full economic impact of new policy choices cannot be evaluated without taking into account the off-farm impacts on water quality and water users.

Conversion occurred on a gross total of 372,000 wetland acres, 7.5% of the total wetlands inventoried at the early date. Direct conversion to urban uses accounted for 30% of wetland losses, but wetlands made up only 10% of the land urbanized. Forty-four percent of wetlands converted were used for agriculture and rangelands, while 20% were converted to forest land. Agricultural and forest land account for 46% and 43% of land converted to urban uses. Agriculture and forestry probably serve as intermediate land uses, but a large fraction of wetlands converted to these uses are ultimately urbanized. It is likely that urban development occurs on previously drained agricultural land, while displaced farmers convert wetlands located beyond the urban fringe for new cropland. Regionally, 86% of wetlands in fast-growth counties are in the Southeast and 85% of gross wetland conversion occurs there. (See also W90-10912) (Lantz-PTT) JF - Wetlands: Concerns and Successes.

Modification of such provisions would benefit groundwater quality by reducing the leaching of agricultural chemicals into groundwater. Crop selection obligations included in farm legislation can be an obstacle to certain crop rotations. The use of crop rotations can lead to improvements in soil fertility, pest management and disease control that reduce commercial fertilizer and pesticide use. The use of such chemicals on the farm influences the potential for such chemicals to reach the groundwater. Planting flexibility is the modification of program provisions that offer commodity program participants a wider choice of crops to plant on their eligible crop acreage base. Many interacting factors, such as the availability of planting alternatives, the relative profitability of crops, and the influence of other program provisions will influence producer responsiveness to any planting flexibility option. Areas where groundwater is most vulnerable to pesticide leaching and where commodity programs may limit the choice of cropping patterns are identified. Planting flexibility appears to offer the greatest potential within the central feed grains region, the northern Great Plains spring wheat region and the Mississippi Delta cotton and feed grain region. The benefits and resulting tradeoffs of planting flexibility provisions should be evaluated and require further research.

AN - 79201339; 2550785 AB - Byssinosis is a hazardous respiratory disorder of workers in natural fiber processing industries and, in the case of cotton, is caused by exposure to respirable dust generated from leafy trash associated with raw fibers. To understand the chemical characteristics of involucral trash components that might contribute to bysinosis, we examined the human airway constricting activity and oxygen radical generating activity of dry, frost-killed cotton bracts. In response to inhalation of aerosolized bract extracts, the expiratory flow rates of human volunteers at 40% of vital capacity during partial forced expiration decreased by 3 to 32%. These values enabled us to identify two potentially byssinogenically active bract specimens, a specimen virtually inactive, and a fourth intermediately so. Using spin trapping techniques of electron spin resonance spectrometry, we found that all specimens catalyzed the generation of hydroxyl (preponderantly) and superoxide radicals from hydrogen peroxide. However, the weakest constrictor was the most potent catalyst, and vice versa. This was consistent with transition metal content of the specimens; the most potent catalyst also contained the largest amounts of those metals, suggesting a Fenton-type reaction mechanisms. Other possibilities for the inverse relationship of airway constricting (byssinogenic) activity with oxygen radical generation are discussed. We also found that neither aflatoxin nor endotoxin, contingent contaminants of bracts, catalyzed oxygen radical production from hydrogen peroxide.

AN - 79229541; 2792973 AB - Diets containing 0.5, 1.58 and 5.0% jimson weed seed were fed to male and female rats (20/group) in a 90-day subchronic feeding study. The alkaloid content was 2.71 mg atropine and 0.66 mg scopolamine/g of seed. Gross clinical observations, body weights and feed and water intakes were recorded weekly. Tear production and pupil dilation measurements were made throughout the study. At 90 days, all of the animals were autopsied and clinical-chemistry analyses, complete haematology and bone-marrow evaluation for evidence of clastogenic effects were performed. Tissues from control (0% seed) and high-dose animals were examined histologically. The principal effects of jimson weed seed were: decreased body-weight gain, serum albumin and serum calcium; increased liver and testes weights (as a percentage of body weight), serum alkaline phosphatase and blood urea nitrogen. Female rats showed more marked responses to jimson weed seed than did males. In addition to the effects seen in both sexes, the females developed decreased serum total protein and cholesterol, and increased serum glutamic-pyruvic transaminase and chloride, red blood cell count, haemoglobin concentration and packed red cell volume. No histological lesions were associated with ingestion of jimson weed seed at 5.0%.

A policy model is developed relying on three decision components where the objective is one of identifying the trade-offs that a regional authority will be confronted with as it strives to balance the preferences of farmers and households while endeavoring to maximize net regional welfare. The basic rule developed indicates that the regional authority must choose a policy whereby any increase (decrease) in regional income as just equal to the decrease (increase) in net benefit to households. While the determination of an optimal tax was selected in the analysis to describe a modeling procedure aimed as assisting in the development of a policy for protecting groundwater quality, the analytical framework is equally applicable to other policy options directed at the same goal. The model developed does require a fair amount of information in terms of details on transport and fate of pesticides, dose-response relationships, and costs. However, the analytical framework does carefully delineate the nature of the problem that the regional authority must confront, and it does focus on the issues that must be considered when developing a policy directed at reducing groundwater contamination.

AN - 79159570; 2764574 AB - Isoelectric focusing (IEF) profiles of pectate lyases (PLs) produced by five different groups of soft rot bacteria were analyzed by using the combined techniques of thin-layer polyacrylamide gel IEF and agarose-pectate overlay activity staining. Four strains of soft rot Erwinia spp. produced three or more PL isozymes. All of eight Pseudomonas viridiflava strains examined produced one single PL with a pI of 9.7. All 10 of Pseudomonas fluorescens strains produced two PLs; the major one had a pI of 10.0 and the minor one had a pI of 6.7. A single PL with a pI of greater than or equal to 10.0 was detected in one strain each of Xanthomonas campestris and Cytophaga johnsonae. PLs of six representative strains were purified from culture supernatants by ammonium sulfate precipitation and anion-exchange chromatography. All purified PL samples macerated potato slices, but to different degrees. The Mrs of alkaline PLs produced by P. viridiflava, P. fluorescens, X. campestris, and C. johnsonae were estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis to be 42,000, 41,000, 41,500, and 35,000, respectively. IEF profiles of PLs were distinct among the bacterial species. Profiles of non-Erwinia spoilage bacteria were considerably simpler than those of Erwinia spp. The PL with an alkaline pI appeared to be the principal or the sole enzymatic factor involved in tissue maceration caused by most strains of soft rot bacteria.

AN - 79143710; 2759992 AB - A liquid chromatographic (LC) method using a 2-step purification technique for the simultaneous determination of 10 carbamates in bovine, swine, and duck livers has been developed. Carbamates are extracted from liver samples with methylene chloride. After evaporation, the residues from the extract are dissolved in methylene chloride-cyclohexane (1 + 1) and cleaned up by gel permeation chromatography. The eluate containing carbamate residues is evaporated to dryness, reconstituted in methylene chloride, further purified by passing it through an aminopropyl Bond Elut extraction cartridge, and analyzed by liquid chromatography using post-column derivatization with orthophthalaldehyde and fluorescence detection. Excitation and emission are set at 340 and 418 nm, respectively. Liver samples for beef, pork, and duck were fortified with 5, 10, and 20 ppb of mixed carbamate standards. The average of 10 recoveries of 10 carbamates at all 3 levels of fortification was greater than 80% with coefficients of variation less than 17%.

AN - 79124154; 2667709 AB - Photosensitization is a sunburn-like condition caused by the presence of certain photoactive compounds in the skin when it is exposed to the appropriate wavelength of light. Most photoactive compounds (phototoxic agents) that cause PS in livestock are of plant origin, others are drugs, chemicals, or endogenous porphyrins. Photosensitization is a disease caused by phototoxic xenobiotics, or by acquired or hereditary dysfunction of (1) heme synthesis or (2) PE excretion by the liver. Hepatotoxins, especially those of plant origin, most frequently are the cause of the condition. Photosensitization primarily is a disorder of sheep and cattle, but all classes of livestock are susceptible. Clinical recognition of the syndrome usually presents no difficulty because of the restriction of lesions to areas of skin unprotected from sunlight. Prognosis generally depends on the extent of hepatic injury. The most important elements of treatment are termination of exposure to the photo- or hepatotoxin, protection from light, treatment and prevention of infection and fly strike, and provision of nutritious feed.

Active iron accounted for 29% of the total tissue iron. The relationship between active iron and the external iron concentration was described by a rectangular hyperbola. Estimates of the external iron concentration at which the active iron fraction was one-half of the maximum 'active' iron concentration indicate that the species could be separated into two groups. Values for monoecious and dioecious hydrilla were similar to that for variable pondweed. Sago pondweed and American pondweed had values which were similar to each other but higher than for the first group. These results may be useful for predicting the efficacy of fluridone, (1-methyl-3-phenyl-5-[3-(trifluoromethyl)phenyl]-4(1H)-pyridinone) , treatments.

Similar changes were also obtained by feeding soybean Kunitz trypsin inhibitor over the same time period.

AN - 79059367; 2741309 AB - Recurrent photosensitization of cattle in Montana has been blamed on Descurainia pinnata, tansy mustard. Two feeding trials were conducted to determine if tansy mustard was phototoxic. Pen-fed cattle consumed 2.4 and 4.1 kg/hd/day of tansy mustard in the 2 trials, and no photosensitization was detected. Liver clearance of BSP was within normal limits, as were blood chemistry values for AST, CK and GGT. Field cases have confirmed that tansy mustard was present and grazed in pastures where affected animals have grazed.

AN - 79193440; 2549368 AB - A two component maize transposon system comprising a stable but trans-active Ac element and a cis responsive Ds element has been established in transgenic tobacco. The development of this system is desirable for the realization of a gene tagging strategy employing these elements in heterologous plant species. Transgenic tobacco with a single transposed Ac element (Ac-18) which has sustained a 4 bp terminal deletion has been identified. Transposase activity of the stable Ac-18 was demonstrated in a tissue culture assay as well as in transgenic plants. When plants containing Ac-18 were crossed with transgenic plants carrying a Ds element, 25%-50% of the F1 progeny showed trans-activation of Ds transposition. Analysis of DNA of several F1 plants showed that each plant displayed a unique pattern of Ds transposition to new chromosomal sites.

AN - 79139438; 2755082 AB - A series of low tar cigarettes (LTC) were smoked and the quantities of condensable mainstream (inhaled) and sidestream (between puffs) smoke compounds were determined and compared to those produced by a high tar, nonfilter cigarette. It was found that the LTC produced large quantities of sidestream smoke condensates, about equal to the high tar cigarette, and contained very high levels of toxic or cocarcinogenic phenols. On an equal weight basis, the LTC emitted more of these hazardous compounds into sidestream and environmental tobacco smoke. Higher smoke yields of a flavor additive and a sugar degradation product indicated addition of such compounds during the manufacture of LTC. It was concluded that, compared to a high tar cigarette, smoking LTC may be better for the smoker, but not for the nearby nonsmoker. Information should be developed to allow smokers to choose LTC that produce lower levels of hazardous compounds in their environmentally emitted sidestream smoke.

Total body weight gains and final body weights were significantly reduced by the DON/T-2 toxin combination but were not significantly affected by the toxins singly. The efficiency of feed utilization was reduced in chicks fed either of the diets containing DON-contaminated wheat. The incidence and severity of oral lesions induced by T-2 toxin was increased in the DON/T-2 toxin combination. Several parameters not altered by DON or T-2 toxin singly were significantly affected by the combination, indicating that the combination may pose a potentially greater problem to the poultry industry than either of the mycotoxins individually.

AN - 79100070; 2745383 AB - In response to consumer concerns about pesticide residues in meat and poultry, a National Residue Program was introduced in the 1960s. Rapidly developing analytical methods and instrument capability resulted in a laboratory-based program of sufficient size and technical capability to quantitatively determine an increasing number of pesticides. In 1985, at the request of the Food Safety and Inspection Service, the National Academy of Sciences evaluated the program and recommended that more emphasis be placed on preventing residues and providing a higher degree of safety to consumers. In response, FSIS made a commitment to increase and improve capability to test for more residues, including pesticides, and to develop or purchase rapid test systems to facilitate the planned expansion of the National Residue Program. Such systems are now being evaluated and integrated into the program. Factors important for acceptability of rapid tests are reviewed in detail.

AN - 79072634; 2745695 AB - During a recent survey of retail fresh foods of animal origin (fish and seafood, raw milk, poultry, and red meats) for organisms of the Aeromonas hydrophila group, we isolated representative strains from the various foods. In this study, we sought to characterize these isolates for biochemical properties and virulence-associated factors and to compare the food isolates with clinical isolates. We identified all food and clinical isolates as A. hydrophila and found that all isolates were typical in their biochemical reactions. Examination of the isolates for various virulence-associated factors indicated that most food and clinical isolates were serum resistant, beta-hemolytic, cytotoxin positive (against Y1 adrenal cells), hemagglutinin positive, Congo red positive, elastase positive, and staphylolysin positive. Mouse 50% lethal doses were log10 8 to 9 CFU for most isolates. All isolates had biotypes identical to those of enterotoxin-positive strains. The public health significance of these organisms in foods is not known at present, although their widespread occurrence and ability to grow competitively in foods kept at 5 degrees C represents a potential hazard.

AN - 79040140; 2471915 AB - The use of a fluorescent stain containing Hoechst 33258 and pyronin Y in the fetal mouse transplacental micronucleus assay allows classification of erythrocytes into three subpopulations on the basis of RNA staining, and permits micronuclei to be scored in all three subpopulations. The youngest erythrocytes stain uniformly positive for RNA (UEs). In older erythrocytes RNA aggregates to give the cells a stippled appearance (SEs) and ultimately disappears, leaving cells which do not stain positively for RNA. Frequencies of micronucleated UEs and SEs were determined at 30 and 48 h following a single dose of methyl methanesulfonate, benzo[a]pyrene, lasiocarpine, monocrotaline or heliotrine. With each agent and dose tested, the frequency of micronuclei increased first in the younger UEs and later in SEs. The use of the Hoechst/pyronin staining procedure, which permits DNA to be distinguished from RNA, minimizes the potential for mis-scoring RNA artefacts as micronuclei and also increases the efficiency of the assay by permitting two age populations of erythrocytes to be scored in each sample.

The farmers irrigated exclusively with groundwater. Farmers ' estimates of energy costs per cubic meter for pumping groundwater served as a proxy variable for the price of water. Climatic regions were defined according to the consumptive irrigation requirements (CIR) of a reference crop, alfalfa. County level CIRs were calculated for the FRIS year, 1984. Despite pronounced differences in climate, crop mix, and irrigation requirements across the three climatic regions, the relatively low elasticity estimates for groundwater demand varied little across climatic regions. Fixed well yields, large fixed investments in irrigation equipment, or the domination of a few crops may all reduce water price influences on water applications per hectare. Narrowing the sample to include only sprinkler irrigated farms resulted in no significant change in elasticity estimates. In spite of this similarity, results indicated statistically significant differences in demand relationships associated with climate. The region with the lower irrigation water requirements clearly has a more price responsive demand for irrigation water than the rest of the west. The estimation results are most applicable to policies that directly affect the price of groundwater. Limitations regarding pricing policies, alone, should bring about water conservation or more efficient water allocation.

AN - 78934361; 2564877 AB - A study was made of the effect of low-dose gamma irradiation on the content of thiamine (B1), riboflavin (B2), niacin, pyridoxine (B6) and cobalamin (B12) in pork chops, and thiamine, riboflavin and niacin in chicken breasts. Gamma irradiation from a caesium-137 source was used to irradiate the samples in a range of 0.49 to 6.65 kGy from -20 to +20 degrees C. Over the range of dose and temperature studied it was possible to derive a mathematical expression for predicting the losses. A calculation was made of the effect of the loss of thiamine, riboflavin and niacin due to irradiation on the overall loss of these vitamins in the American diet. The losses of riboflavin and niacin were of the order of a fraction of a per cent. Pork is an important source of thiamine, but the calculated loss at 1.0 kGy of this vitamin in cooked pork was only 1.5 per cent. There were initial increases with radiation doses up to 2-4 kGy in the measured concentrations of riboflavin and niacin in both pork and chicken. The increases were highly significant, and are of concern both to the study of radiation effects and the chemical method of the determination of these two vitamins.

AN - 78922057; 2708450 AB - The effect of retinoic acid on human fibroblasts was studied in a cell culture model of chronologic aging and photoaging. During early exponential phase, all trans-retinoic acid significantly stimulated growth rate of adult arm-derived dermal fibroblasts but not of newborn or adult foreskin-derived fibroblasts. Retinoic acid also significantly reduced saturation density in most young adult arm-derived lines and all 24 lines derived from old adult arm and foreskin. However, four of ten young adult outer arm (relatively sun-exposed) and one of ten young adult inner arm (relatively sun-protected) fibroblasts lines increased their saturation density in response to retinoic acid. These data suggest that prior sun exposure and/or donor age may influence cellular responsiveness to retinoic acid. Neither the stimulatory nor the inhibitory effect of retinoic acid could be attributed to cell density, to breakdown of retinoic acid in culture, to nutrient depletion or to serum dependency. However, stationary phase fibroblasts from all sites (foreskin, inner and outer arm) showed an increase in filopodia and in intracellular actin after treatment with retinoic acid that was roughly proportional to the degree of growth inhibition, irrespective of donor age. We suggest that retinoic acid induces premature density dependent growth inhibition at least in part by increasing filopodia-mediated cell contact that is in turn directly related to an increase in fibrillar actin.

Insights from the Rural Clean Water Program AN - 19111664; 9102622 AB - Runoff from agricultural land carries sediment, nutrients, bacteria, and pesticides into lakes, rivers, and streams. Elevated levels of these pollutants can harm recreation, water supplies, commercial fishing, and wildlife. The Rural Clean Water Program (RCWP) was initiated in 1980 by the US Department of Agriculture and the US EPA to demonstrate the effectiveness of agricultural best management practices (BMP's) in improving water quality and reducing the offsite effects of nonpoint source water pollution. The RCWP projects most likely to generate the highest offsite benefits are those aimed at preserving or improving water quality in a heavily used lake or estuary within or immediately adjacent to the project area. The extent of the benefits generated will depend on the level of the use impairment and the improvement in water quality. The RCWP projects with nutrient or bacteria problems frequently have a larger number of impaired water uses and potentially higher benefits than do projects with sediment problems. The cost of treating bacteria, nutrients, and sediment with structural practices such as animal waste storage systems and terraces is high compared with the cost of treating sediment and nutrient runoff through low-cost management practices such as conservation tillage. When benefits are potentially very high, more expensive structural practices and improvements appear justifiable, particularly if need to bring water quality to threshold levels where user benefits are generated. About a third of the RCWP projects have strong prospects for offsite economic benefits exceeding costs. Another third have the potential for positive net benefits if additional benefits can be generated by becoming part of larger regional programs that successfully sustain or expand uses of downstream major water resources. A few projects would have had better prospects for net benefits if costs had been reduced by greater reliance on management practices rather than structures such as terraces.

Adult male rats consumed a 0.1% saccharin solution then were treated (IP) with either a 5% NaHCO3 vehicle (negative control), 32 mg/kg LiCl (positive control) or 0.75, 1.5 or 3.0 mg/kg OA. Twenty-four hours later, the rats were given a choice between tap water and the 0.1% saccharin solution. Rats treated with the vehicle or any of the doses of OA exhibited a marked preference for the saccharin solution, whereas the rats treated with LiCl exhibited a marked rejection of the saccharin solution.

Mature peanuts possessed additional resistance to contamination that could not be attributed solely to phytoalexin production. Kernel moisture loss was accelerated in the 29 degrees C treatment compared to the 25 degrees C treatment, and data indicated that the higher soil temperature also favored growth and aflatoxin production by Aspergillus flavus in peanuts susceptible to contamination.

AN - 78938252; 2714720 AB - Currently there is no convenient bioassay to determine the potential toxicity of corn naturally contaminated with Fusarium moniliforme. A short-term bioassay would be useful for future investigations aimed at isolating as yet unidentified toxins produced by this fungus. Two groups of five male Sprague-Dawley rats were each fed one of two F. moniliforme contaminated corn samples, designated CS-1 and CS-2, that were associated with separate field cases of equine leukoencephalomalacia (ELEM). A control group, also consisting of five male rats, was fed uncontaminated seed corn. All animals survived to the end of the study and there were no apparent differences in appearance or behaviour among groups. Weight loss and irregular food consumption occurred in all groups and probably resulted from nutritional deficiencies inherent in the corn diets. Hepatocellular degeneration, necrosis and hyperplasia as well as biliary hyperplasia were found in the test groups only and were attributed to F. moniliforme. Serum transaminase and alkaline phosphatase activities in animals fed CS-1 and CS-2 for 4 wk were significantly increased compared with the controls, while serum bilirubin concentration was increased only in the CS-1 group. Tubular nephrosis was also present in the renal cortex of all animals fed CS-1 and CS-2. These effects may have been related to fumonisins B1 and B2, recently discovered metabolites of F. moniliforme, that were found in both CS-1 and CS-2. Short-term studies of this type may be useful in screening naturally-contaminated grains and other materials for hepatotoxic metabolites produced by F. moniliforme.

The framework is based on the linkages between soil erosion and offsite damages. The linkages are: erosion on the field, movement of eroded materials to waterways, impact of discharged material on water quality parameters, impact of water quality changes on the ability of water to provide economic services, and the economic value of the changes in water use. These linkages need to be modeled in order to estimate the water quality benefits from reductions in soil erosion. Methods for modeling each link on a geographic level, which enables the analyses of national soil conservation, were examined. Areas where data or models were found to be lacking include transport of sediment and nutrients to water systems, impact of discharged materials on water quality parameters, and impact of water quality on ability of water to provide economic services. An economic evaluation of 1983 soil conservation programs was presented as an example of how the framework could be used. A number of simplifying assumptions were made to represent links that could not be modeled with available data.

AN - 79182350; 2549248 AB - Patulin (PAT), a compound produced by certain species of Aspergillus, Penicillium, and Byssochlamys, is frequently found associated with agricultural commodities. PAT has many effects on membrane function, including the inhibition of the isolated Na+-K+ ATPase. In this study, a scanning electron microscope equipped with an energy dispersive spectroscopy X-ray microanalysis system was used to examine individual cultured renal epithelial cells (LLC-PK1) in order to determine the effects of PAT on the relative intracellular ion concentrations. The estimated EC50 (60 min) for both sodium influx and potassium efflux was between 10 and 50 microns for ouabain. For PAT, the EC50 (60 min) was 250 microns for sodium influx and 100 microns for potassium efflux. However, 1 mM patulin at 240 min caused complete reversal of the sodium and potassium content of cells, and 1 mM ouabain at 240 min did not. The effect of patulin on sodium and potassium flux was both concentration and time dependent and was reversed by dithiothreitol and glutathione. PAT (250 microM) but not ouabain (250 microM) induced massive blebbing of LLC-PK1 cells. Thus, the interaction of PAT with cellular membranes involves both alterations in the regulation of intracellular ion content and the cytoskeleton. We hypothesize that patulin alters intracellular ion content via Na+-K+ ATPase and non-Na+-K+ ATPase mechanisms.

AN - 78979613; 2715132 AB - Dry-cured or "country-style" bacon is a low volume specialty product typically made by small producers whose production practices vary widely. These practices include the direct application of dry-cure formulations containing varying concentrations of salt, sugar, flavoring agents, sodium nitrite, and sometimes sodium nitrate, and the use of lengthy curing and processing times. Because of the possibility of generating higher levels of N-nitrosopyrrolidine (NPYR) after frying in this product type compared with pump-cured bacon, an investigation was carried out on dry-cured bacon obtained from cooperating state or federally inspected establishments. Three different samples from each of the 16 plants were analyzed. Only one sample from each of 2 different producers exceeded the Food Safety and Inspection Service (FSIS) action level of 17 ppb NPYR, indicating that the majority of samples tested were in compliance. A significant correlation (P less than 0.01) was found between residual NaNO2 prior to frying and NPYR after frying. The elimination of added nitrate in the dry-cure formulations is recommended.

AN - 78846458; 2643502 AB - Research has verified field observations that cows grazing ponderosa pine needles may abort. The incidence and nature of the abortions produced experimentally simulate very closely those reported by livestock producers and veterinarians. The incidence of experimentally-produced abortions varied markedly from year to year even though the needles were collected in the same general area each year. This suggests that the abortifacient compound(s) in the needles vary from year to year, probably due to environmental and site conditions. The impact of stress (cold and nutrition) as a factor in the abortions was examined. It was concluded that the only effects would be on the willingness of cows to eat the needles. The pine needle abortion problem, what is known of the etiology, and mechanisms of the abortion are reviewed. The usefulness of bioassay systems to study pine needle abortions is discussed.

AN - 78832741; 2536180 AB - Calcium-containing crystals and elevated levels of calcium chloride (CaCl2) and lanthanum chloride (LaCl3) have been previously reported to enhance the proliferative activity of cultured fibroblasts. We have investigated the relative mitogenicity of these agents, whether they function via precipitation on the cell surface and whether they interact with one another. Confluent cultures of newborn foreskin fibroblasts provided with fresh medium containing 10% fetal bovine serum (FBS) in the presence of hydroxyapatite (HA), pyrophosphate (PPi), LaCl3 (La), or additional CaCl2 (Ca) were all stimulated more than control cultures provided with fresh medium and 10% FBS alone as assessed by cell counts 5 days later. Increases in cell yield above the original confluent cell density were 316% for La, 271% for Ca, 189% for HA, 131% for PPi, and 45% for controls. Addition of fresh medium containing 10% FBS and epidermal growth factor or fresh medium containing 20% FBS as additional points of reference yielded increases of 204 and 107%, respectively, over original confluent density. Stimulation induced by La or Ca was significantly greater (P less than 0.001) than the stimulation induced by each of the other treatments. The same treatments added to confluent cultures without a change of medium also renewed mitotic activity, with La and Ca again the most mitogenic and approximately doubling the pretreatment cell yields. Cultures incubated in an inverted position to avoid cell contact with precipitates in the medium were also stimulated by La and Ca, but not by HA and PPi. When added to confluent cultures simultaneously supplemented with optimal additional Ca, La decreased Day 5 cell yields in a dose-dependent manner at low concentrations (0.03-0.2 mM) but increased cell yields over those obtained with 0.2 mM LaCl3 again in a dose-dependent manner at higher concentrations. Thus, while HA and PPi act via precipitation on the cell surface, the more mitogenic agents La and Ca function in solution and appear to stimulate cell division by different nonadditive mechanisms. These findings suggest multiple mechanisms of membrane participation in mitogen responsiveness and in density-dependent inhibition of growth.

AN - 78829228; 2912673 AB - Nineteen spring-calving cows were used in an experiment to study the effect of feeding pine needles on incidence of premature parturitions (abortions) and the associated changes in serum cortisol, estradiol-17 beta and progesterone. The study was conducted over 2 years (1983, seven cows fed pine needles and three controls; 1984, six cows fed pine needles and three controls). Experimental feeding started at an average of 250 d of gestation and continued until parturition. Daily blood samples were taken from the start of feeding through 2 to 4 d after parturition. Feeding pine needles shortened gestation by 16 d and induced a premature normal rise in cortisol and estradiol-17 beta associated with parturition. Cortisol concentrations were also high at the beginning of the bleeding period and remained higher in pine needle-fed cows. An abrupt rise in progesterone concentration occurred after the start of pine needle feeding which then decreased sharply for 7 to 8 d before parturition and did not decrease to control concentrations until after parturition. We conclude that feeding pine needles to pregnant cows in late gestation causes abortions and that these abortions are directly caused by or are associated with changes in steroid metabolism.

This typology is designed to provide some insight into the trade-offs that counties make in terms of economic growth & economic stability. Using two measures of economic performance (% growth in earnings over time, & the year-to-year fluctuations in that growth), nonmetropolitan counties are sorted into one of four quadrants: (1) counties exhibiting high & stable earnings growth; (2) counties with high but unstable growth in earnings; (3) counties with slow but stable growth; & (4) counties with slow, erratic earnings growth. Examining these four quadrants in more detail, overall growth in earnings is decomposed into two components: changes in employment, & changes in earnings per person/year. SE factors most characteristic of local conditions in each of the four growth & stability quadrants are identified.

Strategies for Reducing the Rural/Urban Earnings Gap T2 - Rural Sociological Society AN - 61708091; 89S21046 AB - Two approaches to reducing the long-standing earnings differential between Ru & Ur areas are examined. One, drawn from conventional individualistic models of earnings, views the Ru-Ur gap as the result of individual variations in productivity-related characteristics of Ru & Ur workers, & favors programs to improve the human capital characteristics of Ru workers. The other, drawn from a structural model of earnings, views the earnings gap as the result of Ru-Ur variations in job opportunities, & suggests industrial development strategies to alter this spatial DofL. Data from the 1980 Public Use Microsample are used in a two-stage, multilevel analysis to assess the empirical support for these two approaches. The results indicate that policies designed to enhance the human characteristics of Ru workers will not be sufficient unless they are combined with development initiatives to improve the quality of Ru employment opportunities.

Poor countries fear potential economic losses; & large, pollution-intensive industries are typically owned by the politically powerful upper classes, or by the state. The result has been severe damage to society from industrial pollution. Here, another form of pollution, unique to low-income countries, is described: "poverty-related" pollution, which encompasses many serious environmental problems. It is suggested that the nature of environmental problems in Third World countries is different & more complex than those in industrial countries, where there is a negative relationship between economic growth & environmental quality. In developing countries, however, it can be argued that lack of enforced pollution control may actually have a positive result: if industrial growth without pollution control reduces poverty, it should also reduce poverty-related pollution; & if the resulting environmental improvements offset the environmental deterioration caused by industrial pollution, society will benefit. The need for including environmental management with development policy is stated. 2 Tables, 3 Figures, 28 References. S.

Four watersheds in southwest Idaho were used to evaluate the model. Predicted monthly runoff was compared to actual runoff using a different part of the runoff record than what was used to calibrate the model. Results indicate that the calibrated SPUR hydrology model adequately simulates the volume and timing of monthly runoff for watersheds that have a relatively uniform snow cover. Transferability of the model for uncalibrated watersheds with uniform snow cover was also demonstrated. For most rangeland watersheds where snowmelt runoff is important, however, the spatial variability of snow cover is high; runoff is supplied mainly by one or more isolated drifts. The model works poorly under these kinds of conditions.

Prior to 1987 experiments, a microcomputer-based control system was assembled to control the operation of the facility and provide telephone alarms for soil temperature discrepancies, improper shelter operation, or electrical power interruptions. Commercially available components were used to construct the system which cost approximately US$2000. At the end of a 50-day evaluation period, the system had provided an average plot soil temperature of 27.4 degree C with a setting of 26.7 degree C. The 95% confidence interval for the treatment period average during the tests was between 25.9 degree C and 27.9 degree C. Alarm annunciation and telephone notification were also provided as expected in response to plot temperature extremes and a power outage.

Control of runoff from dairy farms in the watershed may increase net farm income due to cost-share payments and more efficient use of manure nutrients. Appreciation in property values and enhanced recreational experiences were the primary water quality benefits. Insufficient information is available to isolate the marginal benefits attributable to the individual control efforts and to determine optimal levels of water quality improvements.

Since nitrate is highly soluble in water, each of the water balance components must be carefully managed to prevent the transport of nitrate out of the root zone. The water balance components include precipitation and irrigation, stored water in the soil profile, evaporation, transpiration, runoff and percolation. Precipitation management is important to maximize water storage and use. Irrigation is applied when the timing or amount of precipitation is insufficient to meet the crop demand. Surface, sprinkler and drip irrigation systems are discussed as related to management for satisfying crop water needs. When irrigations are scheduled to supplement natural precipitation, the management challenge is to measure and evaluate the irrigation to assure that water is applied in the proper amount and timing. The irrigation system must be managed to avoid excessive runoff or deep percolation. Any excess water leaving the field may be degraded in quality for further use or storage in the underground reservoir. Management of excess water through appropriate drainage is a necessary component of controlling the water balance. Unexpected rainfall can lead to excess water that must be managed. Use of irrigation systems to apply chemicals requires special management. Leaching is required but excess application can degrade groundwater and surface water supplies. Management of the water balance components also requires proper soil management to control infiltration and evaporation.

The rate and the amount of water the soil will absorb is important in designing irrigation systems. A flowing furrow infiltrometer was used to help develop information about how different soils respond to furrow irrigation. After initial setup and calibration, the infiltrometer was used to evaluate infiltration characteristics of a soil that was commonly irrigated using furrow methods. The first study site was a field in continuous cotton, having a soil with a moderately strong surface crust and many small cracks. During the infiltration test, water entered the soil and moved laterally through these small cracks into adjacent furrows. Indications were that the soil cracks extended to the depth of the plow pan approximately 12-14 in. in depth. The cracks qualitatively affected the results of the infiltration test. The second site was also in continuous cotton , with a soil of moderate surface crust with a few small cracks extending only a few mm into the soil. The traveling furrow infiltration data were collected over 1-3 hr time spans. In addition to the acquisitio of soil infiltration rates from the traveling furrow infiltration trailer, furrow evaluations were made on actual field applications to determine the actual performance characteristics of the system. After an evaluation is made, changes in management (furrow stream size, set time lengths, furrow length changes, etc.) can be recommended to improve irrigation accuracy. The system evaluated had rows of 1320 ft with a slope of .2/100 in the evaluation area. A furrow box was installed in the ground next to the gated pipe to measure the inflow stream size. The flow rate into the furrow was found to be 11.5 gpm (avg.) for a total of 19.2 hr. It was found that furrow evaluations will provide needed information for the computer design of irrigation systems in the future without the need for field evaluations.

The practices were used to evaluate the effectiveness of conserving irrigation water and the energy required to pump it. These practices included narrower levee spacing to reduce the water impounded on the field and multiple side inlets to allow more beneficial use of rainfall and to provide for more efficient water delivery within the field. Using multiple side inlets allowed water to be provided to cuts individually or in groups of 2 to 3 rather than water being provided to the entire field through the top cut. The side lateral requires gates so the field, as a whole, requires more gates. Having more gates means more management and labor input. However, once the system is understood, management and labor requirements should be no more rigorous than present management systems. Instead, a lateral rigid plastic or collapsible irrigation pipe could be used to transport water to the cuts. A costly but easy to operate system would be an underground line with risers to several cuts. The objective is to apply only the water the cut needs and to allow freeboard for the utilization of rainfall. Each acre-inch of water saved is 27,000 gallons and requires 0.6 gallons of diesel fuel to pump. All of the study fields indicated that, with the exception of rainfall and seepage, rice farmers can virtually eliminate any runoff. If 4 inches of rainfall (or seepage loss) that would normally run off could be utilized on the fields, the pumping requirement could be reduced to 4 inches.

Open-loop solutions correspond to assuming that participants commit themselves in the initial period to pumping rates in all future periods. Feedback solutions represent a more realistic assumption as farm operators adopt pumping strategies that depend on the reserve stock of water. Comparing the two equilibrium concepts revealed two sources of dynamic inefficiency in the common property aquifer: a pumping cost externality and a ' strategic externality ' that arises from the competition among users to capture the groundwater reserves. The qualitative results show that the open-loop solution captures only the pumping cost externality. The feedback solution captures both externalities and exacerbates the overexploitation of the commons compared to the open-loop solution. Moreover, the dynamic inefficiency resulting from both externalities increases in the number of independent landowners with access to the aquifer.

The Next Step AN - 19067861; 9005711 AB - In a review of the Soil Conservation Service runoff curve numbers, two facts have become evident: (1) The concept of average antecedent moisture condition is for one specific location. (2) The median condition, as represented by the runoff curve number varies by location, which seems to indicate that regional runoff curve numbers may be appropriate for design conditions. As an alternative, infiltration-curve-based procedures can be used where continuous simulation models are used, or where a more-accurate physically-based procedure is needed. Green and Ampt infiltration-equation parameters have been derived for 10 soil-texture classes and have indicated that the results can be used in sensitivity studies of the influence of soil variability on watershed hydrologic outputs. The Green and Ampt equation appears to have wide applicability to modeling the infiltration process.

The southern 120 m (395 feet) of the barriers were removed in the fall of 1981, creating continuous north-south-oriented crop strips from barrier-protected to unprotected. Crop response, soil water content/storage, and simple variable costs using three cropping systems inside and outside of the tall wheatgrass barrier system were compared for the years 1982-1987. Three strips were cropped annually with a rotation of either winter or spring wheat (Triticum aestivum), barley (Hordeum vulgare), and safflower (Carthamus tinctorius). Three strips were in a 3-year fallow-spring wheat-winter wheat rotation, two strips in a fallow-spring wheat rotation, and two strips in a fallow-winter wheat rotation. The greatest soil water gain occurred during the harvest-to-spring period, with a precipitation storage efficiency ranging from about 41% to 57%.

The objective of this study was to determine which, if any, of eight maize inbreds with resistance to maize dwarf mosaic virus strain A (MDMV-A) had a gene or genes for resistance linked to the endosperm color gene (Y sub(1)) on Chromosome 6. Resistant inbreds with yellow endosperm AR234, Ark342, E663, N7B, SC54, SC278, and Tx5858 were crossed onto a susceptible inbred, Mp333, which has a white endosperm Resistant inbred KyB110 with white endosperm was crossed onto the susceptible inbred CI21 that has yellow endosperm. The F sub(2) kernels were separated for kernel color into dark yellow, light yellow, and white kernels. Plants from the dark yellow kernels had a significantly lower proportion of diseased to healthy plants than did plants from white kernels for all F sub(2) populations involving resistant inbreds with yellow endosperm, indicating that each of these inbreds had a gene for resistance linked to Y sub(1).

Residual metribuzin and metabolites were measured by HPLC or TLC methods during or after 91-d incubations of treated soil in the laboratory. Metribuzin degradation was faster in the surface soil than in the subsurface soils. Degradation in the surface and the subsurface horizons were not described by first-order kinetics. Reduced microbial populations and activity corresponded to the reduced degradation of metribuzin in the subsoils.

AN - 16301790; 2812327 AB - Off-site damage from soil erosion in freshwater lakes and reservoirs is an environmental concern worldwide. Suspended sediments are the most visible indicators of off-site damage and a major factor affecting water quality and biological activity in water bodies. A technique is needed to monitor the landscape and locate water bodies with significant suspended sediment concentrations. This paper describes a technique using remote sensing data from environmental satellites to estimate suspended sediment concentrations in lakes and reservoirs. Comparisons of water bodies on multiple Landsat scenes indicate reflectance from surface water is related to suspended sediment concentrations. Using satellite remote sensing, large segments of the landscape could be monitored quickly and efficiently to locate water bodies with significant suspended sediment concentrations.

Herbicide residues were detected in streamflow for only seven days after treatment and did not exceed 7 mg/m super(3). Sulfometuron methyl was not detected in any stormflow and was not found in any sediment. Lack of herbicide residue movement was attributed to low application rates, rapid hydrolysis in acidic soils and water, and dilution in streamflow.

AN - 16047019; 2617156 AB - The gene for the rat GST Ya subunit has been examined in detail as a model for understanding the molecular mechanisms of inducibility by xenobiotics and their tissue-specific regulation. The focus of this article is to describe our current understanding of these mechanisms. The discussion will begin with the classification of the types of inducing agents. These pioneering studies suggested that there were multiple mechanisms for the inducibility of GSTs. In fact, the analysis of GST Ya gene expression has identified two different upstream activating elements and putative protein factors through which different classes of inducers act. Finally, the position-specific and tissue-specific regulation of the GST Ya gene will be discussed. JF - Molecular Toxicology AU - Paulson, KE AD - Genet. Lab., USDA Human Nutrit. Res. Cent.

AN - 16042950; 2611745 AB - Posttranslational acylation of several chloroplast proteins with palmitic acid was recently demonstrated in Spirodela oligorrhiza . We have now identified an in vivo acylated, soluble protein having an apparent M sub(r) of 10 kilodaltons on sodium dodecyl sulfate-polyacrylamide gel electrophoresis as an acylated from of acyl carrier protein (ACP). This 10-kilodalton protein is present in low abundance, and its acylation is light-stimulated. Turnover of the acyl moiety but not the apo-protein is rapid in the light. The acylated 10-kilodalton protein coelectrophoreses with in vitro synthesized palmitoyl-acyl carrier protein and is immunoprecipitated from soluble extracts with an antibody raised against spinach ACP.

AN - 15914948; 2497209 AB - Bacterial exopolysaccharide (EPS) was extracted from infected leaves of several host plants inoculated with phytopathogenic strains of Pseudomonas syringae pathovars. Extraction was by a facilitated diffusion procedure or by collection of intercellular fluid using a centrifugation method. The extracted EPS was purified and characterized. All bacterial pathogens which induced water-soaked lesions on their host leaves, a characteristic of most members of this bacterial group, were found to produce alginic acid (a polymer consisting of varying ratios of mannuronic and guluronic acids). Only trace amounts of bacterial EPS could be isolated from leaves inoculated with a pathovar (pv. syringae) which does not induce the formation of lesions with a water-soaked appearance. Guluronic acid was either present in very low amounts or absent in the alginic acid preparations. All bacterial alginates were acetylated (7-11%). Levan (a fructan) was apparently not produced as an EPS in vivo by any of the pathogens tested. JF - Plant Physiology AU - Fett, W F AU - Dunn, M F AD - USDA, ARS, East. Reg. Res.

The method is sensitive and simple and is based on the formation of a coloured complex with osmic acid. It is specific for -SH and/or for -S-S- or =C=S groups that can be hydrolysed by NaCN to -SH. Both cysteine and cystine could be determined directly in untreated proteins. Hydrolysis was not necessary. Methionine and other amino acids did not react.

Our results indicate that both acid invertase and sucrose phosphate synthase are determinants of sucrose accumulation in melon fruit. However, the decline in acid invertase appears to be a normal function of fruit maturation, and is not the primary factor which determines sucrose accumulation.

I. Optimization of parameters. AN - 15885921; 2485194 AB - super(31)P NMR spectroscopy was used to study in vivo the symbiotic state established between soybean (Glycine max (L.) Merr. cv Williams) and Bradyrhizobium japonicum (USDA 110 and 138). Different experimental conditions were used to maintain perfused, respiring detached or attached nodules in an NMR magnet. The pH of the perfusion medium affected the cytoplasmic pH and the resolution of the spectra. The internal Pi content and distribution were assessed as a function of nodule age and greenhouse growth conditions and the rate of glucose and 2-deoxyglucose uptake into nodules in split and intact states. The major metabolites (glucose-6-P, fructose-1,6-diP, P-choline, Pi, NTP, UDP-glc, and NAD) were readily identified from super(31)P NMR spectra of perchloric acid extracts of nodules with the exception of one unknown phosphorus metabolite. Nodules stressed by glucose deprivation demonstrated movement of Pi between the vacuole and cytoplasmic compartments not previously observed in super(31)P NMR studies.

AN - 15873988; 2460779 AB - White locoweed (Oxytropis sericea Nutt.) is restricted to the top and windswept ridges of the Raft River Mountains. Elevation and soil characteristics have the greatest effect on its occurrence. It is most abundant on the subalpine windswept ridge ecological site (9.2 plants/m super(2)) above 2,380 m. White locoweed apparently can tolerate the extreme environmental stresses of the shallow, rocky, windswept ridges where it is one of the dominant species. White locoweed also occurs in the deep, subalpine loam site (3.8 plants/m super(2)) above 2,865 m, but it is a minor component of this plant community. It is apparently less competitive on the deeper soils, and its population fluctuates more. It exhibits an opportunistic survival strategy on the subalpine loam site by having a large reserve of viable seeds in the soil ready to germinate and establish when environmental conditions are favorable, and then declines with competition from more robust species.

It's a male-order business. AN - 15859101; 2448975 AB - "The way fish are produced now--in very high concentrations in earthen ponds--results in tremendous blooms of blue-green algae," Johnsen explains. "These impart an earthy, musty flavor to the water, and that's picked up by the fish. The authors showed that if catfish are in water with about 0.5 part per billion of the metabolites, in 2 hours' time they'll be off-flavor. White fish pick up the bad taste in a few hours, it takes several weeks for the compounds to be flushed from their bodies, so that they taste good again. "The economic impact of this is very large," he says. "If the fish are off-flavor, the producer can't take them to market which he needs to, and there's a cash-flow bind.

Our restriction endonuclease analysis indicates that there are at least 5 biovars including avian, abortion-enteritis, IPA, M56, and GPIC. Monoclonal antibody studies revealed 4 serovars in the avian biovar.

AN - 15850926; 2436963 AB - Formulations of Bacillus thuringiensis Berliner spores and crystals, encapsulated together within a starch matrix containing no ultraviolet screens, lost all spore viability and insecticidal activity against the European corn borer, Ostrinia nubilalis within 4 d. Encapsulated crystals and spores with Congo red or folic acid as screens exhibited moderate spore viability and retained at least 50% of their original toxicity after 12 d. Congo red was the most effective protectant, followed by folic acid and para aminobenzoic acid. Because Bacillus thuringiensis is likely sensitive to the entire ultraviolet-component in sunlight, ability to provide broad-band ultraviolet protection is required to prolong insecticidal activity effectively.

Pers. (Asteraceae). AN - 15844119; 2436806 AB - The leaf feeder Stolas (Anacassis) fuscata (Klug), from Argentina, was studied in quarantine as a potential biological control candidate of seepwillow, Baccharis salicifolia (R.&P.) Pers. in the United States. No-choice tests were conducted with first-instar larvae on 34 plant species in 7 tribes of Asteraceae and 3 additional families. Pupation occurred primarily on B. salicifolia and to a lesser degree on Gymnosperma glutinosum (Spreng.) Less. and Aster subulatus Michx. No-choice tests were also conducted with adults on 23 plants species representing 5 tribes and 12 genera of Asteraceae. Leaf consumption and longevity were greatest on B. salicifolia and A. subulatus , and oviposition occurred only on these species. Stolas fuscata apparently has a high degree of host specificity. This insect does not attack any economically important plant, and the risk of it feeding on any species other than B. salicifolia is small.

AN - 15841282; 2443963 AB - Regression analyses for plant biomass estimation from physical measurements of individual plant dimensions that are nonlinear have generally used some form of the allometric equation. Use of this equation has most often involved logarithmic transformation of the variables (power regression). Transformation, however, introduces systematic bias into the analyses. Power regression was compared with a bias correction technique and with nonlinear regression for the prediction of the total foliage biomass (phytomass). Crown volumes of one sagebrush and one perennial grass species were used for these evaluations. The bias correction factor was uniformly applied to all the predicted values from power regression. Nonlinear regression avoided this bias by not requiring logarithmic transformation. It was also consistently less variable than either power regression or the correction factor method in estimating actual total phytomass by the allometric equation and equivalent or better in accuracy.

This insect is probably is probably univoltine and overwinters as an adult. Good synchronization was observed between oviposition and larval development of C. basicorne and the occurrence of rosettes and bolting plants of yellow starthistle. In the field, eggs appeared in rosettes from late March to about mid-May; larvae in roots, crowns, and basal stems during April, May, and June, and pupae in larval feeding galleries during May and June. Teneral adults first appeared in late May. JF - Annals of the Entomological Society of America AU - Clement, S L AU - Alonso-Zarazaga, MA AU - Mimmocchi, T AU - Cristofaro, M AD - Reg. Plant Introd.

AN - 15837643; 2429964 AB - The effect of low dose gamma -irradiation on the thiamin content of ground pork was studied in the range of 0-14 kGy at 2 degree C and at radiation doses from 0.5 to 7 kGy at temperatures -20, 10, 0, 10 and 20 degree C. The detailed study at 2 degree C showed that loss of thiamin was exponential down to 0 kGy. An exponential expression was derived for the effect of radiation dose and temperature of irradiation on thiamin loss, and compared with a previously derived general linear expression. Both models were accurate depictions of the data, but the exponential expression showed a significant decrease in the rate of loss between 0 and -10 degree C. This is the range over which water in meat freezes, the decrease being due to the immobolization of reactive radiolytic products of water in ice crystals. JF - INT. J. RADIAT. APPL. INSTRUM., PART C.

AN - 15835798; 2440874 AB - The ingestion efficiency of the predaceous heteropteran Geocoris punctipes (Say) was studied with pea aphids, Acyrthosiphon pisum (Harris), used as prey. G. punctipes consumed aphids up to nearly 50% of their own body weight within a 6-h period. Aphid leftovers (orts) retained about the same proportion of protein (45.8% dry weight) after attack by G. punctipes as was true for intact aphids (42.8%). The amino acid profiles of intact aphids compared with orts differ somewhat, indicating that some proteins were inaccessible or undigestible to the predators. Ingestion efficiency averaged 64.6%, and the approximate digestibility of ingested material was > 90%. This study demonstrates high efficiency in feeding due to pre-oral digestion and internal mechanical disruption of the prey's tissues by this predator's mouthparts.

Levels of beta-phellandrene, camphene and bornyl acetate and terpinolene were significantly reduced with nitrogen added to the equivalent amount of 44.8 g/m super(2). A quantity of 22.4 g/m super(2) did not affect terpene production. Several populations were examined and these did not respond consistently on a regional basis, yet a significant interaction effect was apparent between treatment and local population response. Overall, total yield of terpenes as a function of fertilization was not altered. JF - Oecologia AU - Muzika, R M AU - Pregitzer, K S AU - Hanover, J W AD - USDA For. Serv. For. and Range Sci.

Lindl.) cones is composed of eleven species that can be separated into three feeding guilds: the seed-mining guild, Megastigmus pinus Parfitt, M. rafni Hoffmeyer, Earomyia abietum McAlpine; the cone- and seed-mining guild, Dioryctria abietivorella Grote, Eucosma prob. siskiyouana (Kearfoot), Cydia prob. bracteatana (Fernald), Barbara sp.; the scale- and bract-feeding guild, Asynapta hopkinsi (Felt), Dasineura prob. abiesemia Foote, Ressiliella conicola (Foote), Lasiomma abietis Huckett). In three of four study sites the cone crop decreased from one year to the next. As cone crop size decreased there was a concomitant increase in the percent of cones with more than one species. In addition, there was a shift toward an increased co-occurrence of members of different guilds within a single cone. Both positive and negative interactions were detected between selected species-pairs. JF - Oecologia AU - Shea, P J AD - Pacific Southwest Forest and Range Exp. Stn., USDA/Forest Serv., P.O.

The latter male form was distinguished from typical males by lighter coloration, less carapace and second cheliped spination and significantly (.01 level) smaller second chelipeds. The second cheliped/body length ratio averaged 1.9 in normal males and 0.97 in the feminises form. As the tail yield increased from 36.4% to 51.4% and territorial area was reduced in this form compared to the normal males, further studies in terms of aquaculture potential appear warranted.

I used a computer model to simulate population dynamics of the flat grain beetle, Cryptolestes pusillus (Schoenherr). The results indicate that use of control technologies that cause even a small change in a life history parameter may have a significant effect on population growth when applied over a growing or storage season. The combination of such technologies with other methods of control may improve the cost effectiveness of pest management techniques, even if the noncatastrophic control techniques do not provide adequate control when used alone.

Various blends, formulated on rubber septa, were quantified in the laboratory for release rate and release ratio of the C20 and C21 components; the optimum release ratio (C20:C21) and rate for the capture of males were 78:22 and 10 ng/h, respectively. Three species of the genus Mocis also responded to the velvetbean caterpillar pheromone components: disseverans (Walker), latipes (Guenee), and marcida (Guenee). M. disseverans was captured in large numbers and responded preferentially to baits that released about 50% or more C21. The most M. disseverans were captured at traps containing only C21.

This represents the first successful establishment of a natural enemy of gypsy moth in North America in nearly 50 yr. Levels of pupal parasitism in gypsy moth average 1.9% (maximum 13%). Historical records indicate C. disparis was intentionally imported from India (1972), Japan (1976), and Korea (1984). Laboratory rearing resulted in the eventual release of more than 819,012 individuals liberated in 16 states.

AN - 15819258; 2425050 AB - Can bees accurately gauge accumulating bodily pollen as they harvest pollen from flowers? Several recent reports conclude that bees fail to assess pollen harvest rates when foraging for nectar and pollen. A native nightshade (Solanum elaeagnifolium Cavanilles) that is visited exclusively for pollen by both solitary and social bees (eg. Ptiloglossa and Bombus ) was studied in SE Arizona and SW New Mexico. The flowers have no nectaries. Two experiments were deployed that eliminated "pollen feedback" to the bees by experimentally manipulating flowers prior to bee visits. The two methods were 1) plugging poricidal anthers with glue and 2) emptying anthers of pollen by vibration prior to bee visitation. Both experiments demonstrated that bees directly assess pollen harvest on a flower-by-flower basis, and significantly tailor their handling times, number of vibratile buzzes per flower and grooming bouts according to the ongoing harvest on a given flower. In comparison to experimental flowers, floral handling times were extended for both Bombus and Ptiloglossa on virgin flowers.

AN - 15805705; 2417831 AB - The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), showed a distinct preference for a dry habitat (180 cm/yr rainfall) on the island of Oahu, but they were persistent in dry areas, particularly Makaha Valley. The mean infestation rate was 0.21 and 33.5 flies per kilogram of coffee in wet and dry areas. Dissection of coffee collected in the field showed that larval recoveries per 100 fruits were equal in wet and dry areas, but larval mortality was statistically higher in wet areas; the larvae apparently die from decay of the fruit, especially if they crack open. We conclude that C. capitata and Dacus dorsalis Hendel distribution and abundance are directly affected by the elimination of preferred host fruits and indirectly by climate causing differential effects on their survival in coffee and other fruits in wet versus dry areas.

AN - 15804027; 2418419 AB - The effect of light on host finding and parasitism by Ooencyrtus kuvanae (Howard), an egg parasitoid of gypsy moth, Lymantria dispar L., was studied in the laboratory. Parasitism by O. kuvanae females confined in light or dark cylinders was not significantly different. When parasites were given a choice between light or dark chambers, significantly more chose the light chamber regardless of the presence or absence of an egg mass. However, chambers were significantly more attractive when they contained an egg mass, indicating that an egg mass contributes to host location over short distances. Parasitism of egg masses in dark chambers in which no O. kuvanae were found demonstrates that the parasite may leave these sites after oviposition. Implications for success of O. kuvanae in low-density gypsy moth populations are discussed. JF - Environmental Entomology AU - Odell, T M AU - Chang, Pang-Yuan AU - Walton, G S AD - USDA For.

At all sites, including the feral and sterile release areas, densities decreased to undetectable levels (less than 10 egg masses/ha). In the sterile and feral release areas, parasitism by Cotesia melanoscela) (Ratzeburg) was the largest source of identified mortality and was significantly greater than in the surrounding area or in untreated plots. Within the feral release area, parasitism by Compsilura concinnata (Meigen) and Parasetigena silvestris (Robineau-Desvoidy) was substantial and was greater than in the surrounding area. This pattern was not observed in the sterile release area. This difference may have been caused by differences in gypsy moth phenologies between the two populations.

AN - 15782433; 2377726 AB - Taylor's power law, s super(2) = am super(b), provides a precise summary of the relationship between sample variance (s super(2)) and sample mean (m) for many organisms. The coefficient b has been interpreted as an index of aggregation, with a characteristic value for a given species in a particular environment, and has been thought to be independent of the sample unit. Simulation studies were conducted that demonstrate that the value of b may vary with the size of the sample unit in quadrat sampling, and this relationship, in turn, depends on the underlying spatial distribution of the population. For example, simulated populations with hierarchical aggregation on a large scale produced values of b that increased with the size of the sample unit. In contrast, for a simulated population with randomly distributed clusters of individuals, the value of b eventually decreased with increasing quadrat size, as sample counts became more uniform.

The daily survival of the females was 0.7692. The mortality time when 50%, 90%, and 95% of the parasites had died was determined to be 3.0, 8.77 and 11.4 days, respectively. The mean number of parasitized pupae per female per day, and the mean number of F sub(1) progeny per female per day was 8.11 and 3.65, respectively. The average daily survival for immatures was 0.9763, with an overall survival of 45%. The growth rate per generation proved to be 13-fold. The male to female sex ratio was 1.1:1. When the female parasites were exposed to host pupae at various parasite-host ratios, 100% parasitism was obtained at ratios of 1:0.5 through 1:5, but decreased at higher ratios and ranged from 54% to 74% at ratios of 1:15 through 1:25. Although only 71% parasitism was obtained at a ratios of 1:15, it would appear to be the best ratio for mass production using 1 day old M. domestica) pupae.

AN - 15724731; 2348534 AB - Spruce beetles (Dendroctonus rufipennis ) concentrate early attacks on an initial tree, the "focus" tree, but later attacks occur on adjacent trees, "recipient" trees. The pattern of these initial and following attacks may provide a key for management approaches to deal with spruce beetle outbreaks. Thus, this study was done to determine timing and distribution of spruce beetle attacks among trees in an unmanaged even-aged spruce stand. Repeated observations on 9 plots, each containing 10 formerly uninfested spruce, revealed that the initially attacked trees ("focus" trees) were apparently moisture-stressed due to extensively frozen soils and rapidly warming air temperatures. Continued warm weather caused many more spruce beetles to emerge from hibernation and soils to thaw. Some newly emerged beetles attracted by odors from beetles already established in focus trees attacked the focus trees, but many attacked nearby unstressed trees ("recipient" trees). As a result, all focus trees and many recipient trees within 10 m of focus trees were killed. Furthermore, many recipient trees weakened by unsuccessful attacks were reattacked the following season.

(Symphyla: Scolopendrellidae) predators of arthropods and nematodes in grassland soils. AN - 15688290; 2313683 AB - Inspection of the gut contents of 106 symphylans (Symphylella sp.) collected from 7 grassland sites in the central United States revealed that, of the 58 animals with food inclusions, 94.8% had been feeding on animal prey. Most gut contents were comprised of soft-bodied arthropods (prostigmatid, acarid, and nymphal oribatid mites, collembolans, and symphylans) and nematodes. Fungal material was a minor component of gut contents, typically single spores or small packets of fungal material with the remains of mycophagous arthropods (collembolans and mites). Detrital material was identified in only 4 animals. Although symphylans are usually considered to function as detritivores or root-feeders, these findings suggest that species of Symphylella function as omnivorous predators in grassland soils in the central United States.

AN - 15650766; 2291538 AB - Flight activity of corn rootworm beetles, the northern (NCR), Diabrotica barberi (Coleoptera: Chrysomelidae), and western (WCR), D. virgifera virgifera , was monitored using malaise traps placed at the edges of two small cornfields. Populations of beetles in the fields peaked while corn was flowering, but capture in malaise traps remained low until silks had dried. Capture of NCR and (to a lesser extent) WCR then increased and remained high through the season. Malaise traps were constructed to permit separate collections of beetles that entered on each of two opposite sides. Female NCR that were captured in sides that faced toward corn tended to contain fewer mature eggs than those in sides facing away from corn. These findings support the hypothesis that female NCR emigrate from cornfields to feed when fresh silk and corn pollen (favored foods) become unavailable, but that egg-laden NCR actively seek corn when searching for oviposition sites.

Percent successful parasitism (that which resulted in the production of adult parasitoid progeny) increased with host developmental state, reaching 95% in 5th instars, but fell to 63% in prepupae. While 25% of the exposed prepupae metamorphosed to pupae, none developed into adults. E. bryani maggots emerged from only 5% of H. zea pupae. The mean number of fly puparia and adults produced per successfully parasitized larva increased with host stadium, reaching 14.5 plus or minus 1.33 (SEM) and 10.6 plus or minus 1.02, respectively, in prepupae. The sex ratio of adult parasitoid progeny per host larval stadium was variable, and did not appear to follow a pattern. A formula for calculating a "host favorability index" is presented. This index allows a direct comparison of the overall impact and reproductive potential of E. bryani attacking hosts of varying developmental states.

AN - 15649214; 2297050 AB - Entomopoxviruses (EPV) are currently being considered as candidate grasshopper (Orthoptera: Acrididae) microbial control agents. Classical techniques for diagnosing infections in grasshoppers are laborious, time consuming, and sometimes inaccurate. Specific murine monoclonal antibodies were developed against an EPV from Melanoplus sanguinipes (Fab) for use in a nitrocellulose-based enzyme-linked immunoassay (dot-blot). An IgG sub(2b) monoclonal antibody was used to diagnose infections in grasshoppers 13 days following injection with virions. Of 25 grasshoppers that had patent infections microscopically, 22 produced positive results on the dot-blot. In a second test, 39 patently infected grasshoppers all produced positive results. Seven additional grasshoppers in the first test and 2 in the second test gave positive reactions in the dot-blot method but virus was not detected upon microscopic examination.

AN - 15648275; 2292422 AB - Enhancement of an insect pheromone response by green leaf volatiles is reported for the first time in the boll weevil, Anthonomus grandis Boh. (Coleoptera: Curculionidae). Single cell recordings from antennal olfactory receptors revealed a class of cells selectively responsive to six carbon alcohols and aldehydes (i.e., "green leaf volatiles"). Field tests with released weevils demonstrated enhanced trap captures with trans-2-hexen-l-ol, cis-3-hexen-l-ol, or l-hexanol paired with grandlure, the boll weevil aggregation pheromone, when in competition with grandlure alone. Although dose-response curves constructed from electroantennograms were indicative of similar populations of receptor cells for selected six carbon alcohols, one of the compounds tested, cis-2-hexen-l-ol, was inactive in field tests. Trans-2-hexenal was active in single cell recordings, but was also inactive in field tests. In tests in cotton fields with indigenous weevil populations, trans-2-hexen-l-ol not only enhanced pheromone trap captures, but also extended the longevity of attractiveness of pheromone-baited traps.

(nonhost plant), and cotton plants with or without nectaries and with or without glands to Microplitis croceipes Cresson (Hymenoptera: Braconidae) was determined in a wind tunnel. Female parasitoids flew significantly more to glandless than to glanded cotton; response to nectaried and nectariless cotton was similar. Velvet leaf and cotton were favored significantly over groundcherry; parasitoids being equally responsive to both host plant species. Addition of larval frass alone or in combination with host larvae significantly improved the attractivity of the nonhost plant (groundcherry) to the parasitoids. There was no difference in attractiveness of groundcherry terminals with or without host larvae. Parasitoid search time was significantly increased with addition of larval frass.

AN - 15647070; 2289953 AB - The displacement of indigenous Bradyrhizobium japonicum strains of serocluster 123 in soybean (Glycine max (L.) Merr.) nodules in favor of a more effective inoculant strain has been suggested as an approach to enhance N sub(2) fixation and thereby increase soybean productivity. We previously identified soybean genotypes that restricted the nodulation and competitiveness of the serotype strain USDA 123, but did not affect the nodulation or competitiveness of many other serocluster 123 isolates. It was the objective of this work to identify a soybean genotype that reduced the nodulation and competitiveness of serocluster 123 isolate MN1-1c, a strain that nodulated the previously identified USDA 123-restricting genotypes very well. Our results demonstrated the ability of PI 417566 to reduce the nodulation and competitiveness of MN1-1c in favor of the inoculant-quality strain CB1809, and indicated that soybean genotypes may be used to exclude specific isolates or subpopulations of serocluster 123.

AN - 15639112; 2289552 AB - Fourth instar gypsy moth larvae, Lymantria dispar , from a laboratory colony were transferred between artificial diet and three ages of leaves from a preferred tree, Quercus rubra . Mortality after transfers was generally minimal (< 13.3%) and did not differ from mortality of larvae remaining on the same food. Larvae that were transferred to a new food accepted artificial diet and the early season foliage that is normally eaten by early instars as readily as larvae that were not transferred. Pupal weights from larvae continually fed artificial diet or transferred from artificial diet to early season foliage were not significantly different. First instars of wild larvae fed artificial diet gained less weight after 3 weeks than foliage-fed first instars. Pupal weights of wild larvae transferred from June foliage to artificial diet as fourth instars were not significantly different from pupal weights of wild larvae remaining on foliage. Thus, the response of laboratory colony larvae to artificial diet was superior to that of wild larvae. JF - Entomologia Experimentalis et Applicata AU - Hajek, A E AD - USDA, ARS, Plant Prot. Res.

AN - 15630670; 2268781 AB - Seven observers independently sampled the bird assemblage in oak-pine woodlands in central California by completing 5-min point counts at 210 counting stations during April 1986. Either total counts or frequencies, or both, could be used for monitoring trends in relative abundance of birds. However, density estimates have limited usefulness for most monitoring efforts. Results showed that the observer was a major source of variation in counts and frequencies. We recommend (1) that three or more observers sample all sites in a system to monitor trends in bird populations on the small geographic scale represented by this study, (2) that observers pass a performance test, including hearing, to be included on a monitoring field team, and (3) that all observers undergo training prior to field sampling. However, even these measures will not eliminate all effects of observer variability, requiring caution by practitioners when interpreting results.

AN - 15620785; 2269980 AB - Growth and nutrient utilization of alfalfa (Medicago sativa L. cv. Arc) and common bean (Phaseolus vulgaris L. cv. Carioca) were studied in an acid soil adjusted to eight levels of soil acidity by lime addition. Application of lime significantly (P < 0.05) increased shoot and root growth for both species. However, common bean was far less sensitive to soil acidity than alfalfa. Maximum alfalfa growth was obtained at a soil pH of 5.8 and maximum bean growth was achieved at pH 5.0. Root and shoot growth of both legumes was positively correlated (P < 0.01) with soil pH, exchangeable Ca and exchangeable Mg and negatively correlated (P < 0.01) with soil exchangeable Al. Common bean had a lower internal P requirement for maximum growth and was more efficient than alfalfa in taking up Ca and Mg. These characteristics would contribute to the favorable growth of common bean in acid-infertile soils.

AN - 15602614; 2253395 AB - Ten lactating Holstein cows that had been given multiple injections of Listeria monocytogenes (serotype 4B, Scott A strain) via the intramammary route were allotted to 2 groups: group 1 (n = 5) was treated with the synthetic glucocorticoid, dexamethasone (0.04 mg/kg of body weight), for 3 consecutive days, and group 2 (n = 5) served as controls. Two days after the initial dexamethasone injection, the number of L. monocytogenes in the milk had increased nearly 15-fold (1.16 log sub(10)) over pretreatment values. On day 3, Listeria numbers in the milk had increased by 1.83 log sub(10), compared with pretreatment values. By day 4, Listeria numbers in the milk were approximately 100-fold (2.03 log sub(10)) greater than pretreatment numbers. Numbers remained high through day 7 and, by day 11, approached pretreatment numbers.

Ceca were surgically removed from chickens immediately after euthanasia, inverted on glass rods, and then rinsed with sterile saline before being exposed to S. typhimurium in a solution of saline containing the carbohydrate to be evaluated. Attachment of S. typhimurium to ceca was reduced in 1-week-old chicks in the presence of N-acetyl-D-galactosamine, L-fucose, D-galactose, L+arabinose, and D+mannose. Minimal or no reduction in attachment of S. typhimurium was noted when ceca from 2-week-old chicks were exposed to the same compounds. Carbohydrates investigated and found to be ineffective for reduction of S. typhimurium attachment to chick ceca were D+fucose and N-acetyl-D-glucosamine.

The degradation flux of each isomer continued to increase for 60 days after treatment and then decreased. Among the different isomers, the beta -isomer degradation was the slowest, followed by delta -, alpha - and gamma -isomers. Several reasons are suggested for this degradation behavior of different HCH isomers. Partition distribution coefficients (K sub(d)) of all isomers showed a positive correlation with incubation time and their respective degradation rates. This study was compared with non-flooded plots where all the isomers persisted for a longer period.

AN - 15589540; 2230017 AB - Eighty-five strains of Pseudomonas solanacearum isolated from diseased tubers and soil samples from a 0.3-ha field near Hastings, Florida, were heterogeneous for antibiotic production and sensitivity, pathogenicity, and carbohydrate utilization. Major variation was noted in antibiotic production and strain aggressiveness. All strains belonged to race 1, biovar 1. Eight strains belonged to one of three groups: 1) weakly aggressive to potato cultivars Atlantic (susceptible) and Ontario (moderately resistant), 2) highly aggressive to both potato cultivars, and 3) highly aggressive to Atlantic but weakly pathogenic toward Ontario. All strains were aggressive pathogens to the tomato cultivar Rutgers and the eggplant cultivar Black Beauty. Although the Florida strains belonged to biovar 1, they differed in ability to oxidize galactose, arabinose, and lactose. All strains elicited the hypersensitive response in leaves of the tobacco cultivar Bottom Special. When the 85 strains were tested for antibiotic production against 26 indicator strains, there were 23 phenotypes for antibiotic production and 12 for antibiotic sensitivity.

The viscosity of the reaction mixture decreased sharply relative to the release of reducing groups, indicating random hydrolysis of the mannan backbone of the polysaccharide. The endo- beta -mannanase was purified by ion exchange chromatography and shown to be free of alpha -galactosidase and beta -mannosidase. The M sub(r) was estimated to be 43 000 by gel filtration.

AN - 15572865; 2226858 AB - Cotton leaf, bract, fibre from opened bolls, and soil samples were collected weekly during two growing seasons (1984, 1985). Total and Gram negative bacterial populations were determined for each sample. Representative bacterial isolates were identified and endotoxin concentrations determined. For both years total and Gram negative bacterial populations on all sample types remained relatively stable until plant senescence. Afterwards, until plant death by frost, counts for all samples increased dramatically. Enterobacter agglomerans was the predominant species on leaf and bract, whereas the "all other" Gram negative bacterial species classification was the most common on fibre, with E. agglomerans a close second. Senescence affected the occurrence of the species isolated. Statistical analysis partitioned by sample type showed strong correlations between endotoxin concentrations and certain bacteriological and environmental variables.

AN - 15567092; 2226544 AB - This study tested the sensitivity of a hierarchical foraging model to plant community composition, landscape composition and cattle stocking rate. Diet selection was represented as an overmatching process. Relative species preference (proportion in diet/proportion in herbage) was expressed as an exponential function of relative palatability. Habitat selection was described as a biased matching response in which relative community preference (proportional foraging time/proportional area) was a linear function of relative availability of food plants, weighted by palatability. Interaction of palatability and availability effects resulted in complex diet selection responses to community composition; response of landscape utilization to community availability was simpler and less volatile.

AN - 15563820; 2228682 AB - Genetic low density lipoprotein (LDL) deficiency and high density lipoprotein (HDL) excess have been associated with enhanced longevity. This investigation assessed the prevalence of lipoprotein abnormalities in octogenarians free of clinical evidence of cardiovascular disease (CVD) in the Framingham Heart Study. Plasma lipid and lipoprotein cholesterol determinations were carried out by standard techniques between 1971 and 1974. Participants who were free of clinical evidence of CVD in an examination approximately 10 years later (1981 to 1982) had their lipoprotein values tabulated based on the earlier examination. There were 106 women and 57 men who met these criteria, with mean ages of 83.3 and 82.9 years, respectively, at examination 16 (called cases). Mean levels ( plus or minus SEM) of LDL cholesterol in cases were 152 plus or minus 3 mg/dL for women and 147 plus or minus 5 mg/dL for men. For HDL cholesterol, these values were 57 plus or minus mg/dL for women and 46 plus or minus 2 mg/dL for men. These values were not statistically different from those of other study subjects (who did not meet the CVD criteria or were deceased) or middle-aged controls.

Heliothis virescens (F.) was the host used. To study host instar-age acceptance, females of each species were exposed in the laboratory to 1st instar larvae, 24 and 48 h old, 2nd instar larvae, 72 and 96 h old, 3rd instar larvae, 120 and 144 h old, 4th instar larvae, 168 and 192 h old, and 5th instar larvae, 216 and 240 h old. A host larva was considered to be accepted by a female if she laid an egg in the larva. The full range of host instar-age acceptance was 1st instar-24 h old to 5th instar-240 h old for M. croceipes , 1st instar-24 h old to 5th instar-216 h old for M. demolitor , 1st instar-24 h old to 4th instar-192 h old for C. kazak , and 1st instar-24 h old to 4th instar-192 h old for H. didymator .

AN - 15476536; 2207657 AB - The current state of landscape research does not clearly direct environmental managers toward the appropriate choice of terminology to characterize and assess the aesthetic quality of particular landscape types. This study examined the ability of physical, artistic, and psychological descriptor dimensions to predict aesthetic preferences for rural river, forest, and agricultural landscape scenes. Multidimensional scaling analyses were used to identify the salient dimension subjects used to express their aesthetic preferences for scenes within each type; these dimensions were interpreted quantitatively through correlations with sets of descriptor rating scales. The results generally showed a strong commonality in the dimensions of preference across landscape types, but also pointed to the uniqueness within landscapes.

AN - 15476359; 2195091 AB - Experimental inoculation of 1-day-old male broiler chickens with avian reovirus or Staphylococcus aureus caused tenosynovitis of the gastrocnemius and digital flexor tendons. Reovirus inoculation by either the oral or footpad route initiated a diffuse lymphocytic infiltration in the peritendineum, synovial membrane, and epitenon from 1 to 5 weeks postinoculation. Heterophils were not a predominant feature of the inflammatory response, but when present they were localized with fibrin in and around synovial spaces. The prevalence of microscopic tendon lesions was less common with staphylococcal infection than with reovirus infection.

Defoliation reduced total and residual biomass yields and increased aboveground relative to belowground investment of total biomass and N in A. smithii individuals. Elevated N-addition rate increased tillering and leaf extension rates and residual biomass yield of A. smithii . Total biomass and N yields of A. smithii individuals were reduced, and proportional investment of biomass and N in roots was increased, by association with the larger A. frigida neighbor.

AN - 15472221; 2207804 AB - Membranes can be tethered easily to the incubation vessel with the aid of tabs or small pieces of membrane (10 x 15 mm). Other materials can be used; however, tabs of nitrocellulose or nylon membrane absorb very little of the incubation solution. The tab is lightly touched to a drop of cyanoacrylate glue so that just the edge (1 mm) is coated. The upper 1 mm of the membrane to be analyzed is attached to the tab. Attaching only one end to the vessel is usually sufficient to prevent multiple strips in the same container from making contact. Changing buffers is aided by this procedure, since solutions can be rapidly removed without concern over losing the membrane. JF - Biotechniques AU - Triplett, BA AD - USDA, ARS, Southern Reg. Res.

AN - 15468284; 2198324 AB - Habitat preferences and dispersal patterns of female screwworm, Cochliomyia hominivorax (Coquerel), flies were studied in tropical habitats in Mexico and Belize. Flies were captured and released in two contrasting habitat types, open pasture and dense forest, situated such that movements within and between habitats could be measured. Flies were abundant at both study areas, and about one third of marked flies were recaptured at least once. For original captures and subsequent recaptures, there was a clear preference for forest habitats. Dispersal behavior of flies was significantly related to habitat types; flies in open habitats tended to disperse greater distances than those within forested habitats. There was a net movement of flies from pasture into forest habitats. These data indicate that surveys or studies should consider forested habitats as preferred sampling locations.

AN - 15450630; 2180057 AB - Botryosphaeria dothidea invades bark of peach trees through wounds and lenticels. The effect of water stress on disease development at lenticels was studied in 1-yr-old peach trees that were inoculated by applying suspensions of conidia on nonwounded stems. From May to September 1985, inoculated trees were irrigated daily or had water withheld for 2,4, or 6 days in each 8-day cycle. At the end of the test, trees with the 6-day withholding had higher mean values for number of gum exudation sites and number of lesions and a higher percentage of bark necrosis than trees in the other treatment groups. Based on observations in November, stress imposed 2-6 mo after inoculation resulted in a dramatic increase in number of lesions and in percentage of bark necrosis. Stress imposed during the period of August to October consistently caused an increase in disease severity. JF - Plant Disease AU - Pusey, P L AD - USDA-ARS, Southeastern Fruit and Tree Nut Res.

AN - 15448477; 2183976 AB - This study was part of a larger investigation on the biological control of stalk rot of corn (Zea mays L.) through application of mycopathogenic fungi on above-ground surface (phylloplane) of the corn plant conducted at Iowa State University, Ames, IA. The objectives were to determine if grain yield is an effective trait for testing the interaction of selected mycopathogenic fungi with corn genotypes and whether the application of mycopathogens to the corn phylloplane had an effect on yield. Plants were treated in the phylloplane with aqueous spore suspension of mycopathogens Gliocladium roseum (Link) Bainier, Gonatobotrys simplex Corda, and Sphaeronaemella helvellae (Karsten) seeler, and water as control. Selection and breeding of inbreds with high yield response to mycopathogens could result in genotypes that, in the presence of a compatible mycopathogen, would suppress stalk rot development and have greater yield potentials.

AN - 15445002; 2179209 AB - Syrian hamsters were orally administered ground plant material from either Solanum sarrachoides, S. melongena, S. eleagnifolium or S. dulcamara . Six of eight hamsters administered S. eleagnifolium and eight of 10 hamsters administered S. dulcamara died following administration of plant material and had gastric glandular mucosal necrosis and small intestinal mucosal necrosis with little inflammation. Hamsters administered S. sarrachoides or S. melongena did not die and had only lesions compatible with gastric distension. Both S. eleagnifolium and S. dulcamara contained solasodine glycoalkaloids(s), and S. dulcamara also contained an equal amount of other glycoalkaloids which were probably derived from soladulcidine (dihydrosolasodine). The lesions produced by these two plants were similar to those reported earlier to be caused by sprout material of S. tuberosum (in which solanidane alkaloids predominate) and by an alkaloid extract of S. tuberosum sprouts.

AN - 15444592; 2179063 AB - In the Delta area of Mississippi, a 13-month sampling program in old-field habitats adjacent to cotton fields demonstrated high densities of Pisaurina mira in June, which was coincident with high Lygus lineolaris populations. In July, P. mira populations were lower by 50% and L. lineolaris by almost 100%. From August through October, P. mira populations continued to decline while L. lineolaris increased. Field observations in the same old-field habitats indicated L. lineolaris to be the most frequently captured prey item of P. mira . In laboratory feeding experiments over a 3-year period, all P. mira individuals consumed L. lineolaris and 22 of 35 other species of co-occurring potential arthropod prey. These data suggest that the predator P. mira may affect L. lineolaris populations and can survive on other prey when L. lineolaris is less abundant.

Specimens were collected in 10 different habitat types and in four vegetational strata. Old-field habitats yielded the most species (152) and residential lawns the fewest (14). Considering all habitats sampled, the ground layer produced 111 species, the herbaceous strata 133, the shrub layer 49, and the tree strata 30 species. The sweepnet method of capture obtained 128 species, pitfall 95, hand 61, vacuum 53, and bagging 19 species. The largest number of species were obtained in spring and early summer (maximum of 125 in May), with the fewest in mid-winter (Jan. = 24). Twenty-one species were considered abundant, 51 common, 67 uncommon, and 95 rare. Additions to the state list of Dorris (1972) number 102 species, for a new state total of 364 species.

AN - 15442332; 2178624 AB - Soil microorganisms in the rhizosphere are important in the revegetation and stabilization of drastically disturbed areas in the semiarid Southwest, as the microbial community is often responsible for the modification of many adverse soil properties. In this study, the soil microbial community was evaluated in the rhizosphere and the nonrhizosphere of two grass species, galleta (Hilaria jamesii ) and alkali sacaton (Sporobolus airoides ), and a shrub, fourwing saltbush (Atriplex canescens ), growing on a reclaimed coal mine spoil 3 months to 2.25 years after topsoiling and revegetation. Many soil chemical properties and most microbial populations decreased in both soil zones with reclamation age. However, the rhizosphere of galleta and alkali sacaton still had significantly higher levels of soil N, P, organic matter (OM), and microbial populations than did the nonrhizosphere after 2.25 years of plant growth. The rhizosphere of fourwing saltbush had significantly higher EC and SAR values and fungal propagule levels than did the nonrhizosphere. The rhizospheres of the two grass species had significantly higher levels of N, P, OM, and bacterial populations than the rhizosphere of fourwing saltbush.

AN - 15439714; 2175406 AB - Aspergillus parasiticus Speare and A. sojae Sakaguchi & Yamada are two morphologically similar species belonging to Aspergillus sect. Flavi . Accurate identification of these species is important because A. sojae is used in oriental food fermentations while A. parasiticus is highly undesirable in food products because it produces the potent carcinogen, aflatoxin. In testing members of Aspergillus sect. Flavi for resistance to the glycopeptide antibiotic, bleomycin, it was noted that A. sojae and A. parasiticus responded differently to bleomycin in minimal media. In this study we compared growth of A. parasiticus and A. sojae in media with and without bleomycin to determine if media with bleomycin could be used as a taxonomic tool in distinguishing between these two species.

AN - 15439693; 2174784 AB - The effect on sex ratio and size of progeny produced was examined for a greenhouse population of the gregarious bee Osmia lignaria propinqua Cresson under conditions of unlimited nest holes of four diameters. Significantly more female progeny (the larger sex) were produced in wide-diameter holes than in narrow-diameter holes. Progeny of both sexes were significantly larger in wider holes than in narrow holes. A significant interaction of sex and straw diameter suggests that females increased in size more than males with increasing hole diameter. Females made little selection based on hole diameter with two exceptions: few nests were made in the narrowest hole diameter (5 mm); and there was a minor, but statistically significant tendency for larger bees to make a greater proportion of their nests in the widest hole sizes (7 and 8 mm).

AN - 15437830; 2178918 AB - In 1981 the United States Department of Agriculture (USDA) Biological Control of Weeds Laboratory (BCWL, Rome, Italy) started investigating the host specificity of P. inspersa as a candidate for biological control of C. diffusa and C. maculosa , and in 1985 the investigation was completed at the USDA Biological Control of Weeds Laboratory at Albany, California. Thirty five species of plants in the family Asteraceae and 23 other species in 8 related families were tested. Larval survival beyond 1st instar occurred only on Centaurea spp. except for 1 larva found in Cnicus benedictus L. P. inspersa is stenophagous on Centaurea , therefore, a good candidate for introduction into North America.

AN - 15437080; 2175416 AB - The uptake and expression of cucumber mosaic viral (CMV) RNA by tobacco protoplasts was examined using both square wave and exponential wave electroporation pulses. These electropulses, when supplied at sufficient field strength for a critical duration, enabled RNA to be incorporated and expressed in more than 60% of the surviving protoplasts. The results of experiments using these two electroporation wave forms showed significant differences in RNA uptake and expression. The number of viable protoplasts and cells showing expression of RNA was higher over a much broader range of experimental conditions using the square rather than exponential wave generator, even when both machines were optimized for maximal performance.

A monoclonal antibody (MAB) to the arylphorin of Heliothis zea (Boddie) distinguishes remains of fifth instars in enzyme-linked immunosorbent assay (ELISA) of fed predator extracts from the remains of all other instars and eggs of this and related species. This demonstrates the feasibility of using MAB-based ELISA in life table and other long-term quantitative predation studies.

Duration of the larval stage and preoviposition period differed significantly between laboratory-reared and wild lines. Growth rates, growth times, and population structure also differed significantly. Intrinsic rates of increase, mean generation times, and mean ages of reproduction differed: 0.14 versus 0.09-0.11 females per d, 31.7 versus 40.9-43.9 d, and 58.5 versus 73.1-79.2 d, respectively.

AN - 15430026; 2165058 AB - Oviposition by overwintered univoltine, monomorphic adults of Neochlamisus platani (Brown) begins in mid-May. Stalked eggs encased in fecal material are deposited usually on the abaxial surface of American sycamore and London planetree leaves. The eggs are highly parasitized by Tetrastichus chlamytis Ashmead during the 6-wk oviposition period. Twelve caged females laid 1,826 eggs during 6 wk of adult life. Punctuated feeding by larva on expanding new leaves results in a pronounced shot-hole appearance. Case-bearing larvae use both mandibles and bifid tarsal claws to maintain defensive attachment to the leaf surface when disturbed. Last instars often wander from feeding site to molt; they attach at stipules and resemble leaf axillary buds. Eggs incubated under natural conditions develop in 13-15 d. Of eggs collected for seven successive weeks, 32% produced larvae, 37% produced parasites, and 27% were apparently fed upon by a predator.

The metal ions, Cu(II), Ni(II) and Zn(II), were immobilized by iminodiacetic acid (IDA) coupled to TSK gel 5PW (10 mu m). Two types of gradient elution (imidazole and pH) were used to evaluate peptide retention by the metal ions. A decreasing pH gradient and an increasing imidazole gradient eluted the peptides in similar order. Modified N-terminal residues resulted in negative contributions to retention.

Two peaks with RBP immunological activity were eluted: the smaller peak containing at least 86% of the vitamin A, which was identified as transthyretin-bound RBP; the larger peak containing a small amount (< 14%) of a highly fluorescent vitamin A-containing protein, identified as free RBP. Both free and transthyretin-bound RBP can be quantified by this method. JF - Clinical Chemistry AU - Burri, B J AU - Kutnink, MA AD - USDA/ARS/PWA, West. Hum. Nutr. Res. Cent., Biochem. Res.

AN - 15426657; 2165192 AB - The solitary pupal parasite Urolepis rufipes (Ashmead), a recent isolate from house fly and stable fly puparia in eastern Nebraska, was studied to evaluate its potential as a biological control agent for these fly species. Parasitism was highest at 25 degree C for two age classes of host pupae. Parasite-induced mortality attributed to host stinging, excluding emerged parasites, increased with temperature, and generally was significantly higher than parasitism. The number of emerging male to female parasites was about equal and males generally began emerging 1 day before females. Development was more rapid than for most other pteromalid parasites of filth flies requiring 10-15 days for first male emergence at 25 degree C. Apparent diapause was evident with this species and was activated by the temperature at which the developing progeny were subjected.

AN - 15425283; 2164929 AB - Interactions between larvae of the banded cucumber beetle (Diabrotica balteata LeConte), a resistant cultivar ("Regal"), a susceptible sweet potato clone (SC-1149-19), and a nematode arthropod parasite, Heterorhabditis heliothidis (Khan, Brooks, and Hirschman 1976) Poinar, Thomas, and Hess 1977, South Carolina strain, were evaluated. Plant resistance in the cultivar Regal was active against younger larvae. Reduced adult weights and fewer emerging adults were observed when second instars were exposed to the parasite on sweet potato tissue, and the eclosion period was longer for second instars and reduced for third instars. Exposure to the resistant cultivar reduced the eclosion period of second instars as compared with larvae exposed to the susceptible clone, whereas no differences were observed among plant entries for third instars. When second instars were exposed to the parasite, the eclosion period was reduced and no differences were noted for third instars. The duration of the eclosion period was negatively correlated with adult weight. JF - Environmental Entomology AU - Schalk, J M AU - Creighton, C S AD - U.S. Veg.

AN - 15422044; 2165464 AB - The design and operation of a semiautomated instrument for measuring total and radiolabeled CO sub(2) evolution from soil is described. In the recirculation mode, headspace gases are recirculated in a closed loop through an infrared (IR) detector. After a steady state is achieved, the concentration of total CO sub(2) is read and recorded. The variability associated with super(14)CO sub(2) evolution from soil (carbofuran hydrolysis) was greater with sprayed soil than with slurred soil, suggesting that the slurry method resulted in a more homogenous distribution of pesticide throughout the soil. The low analytical variability associated with measurements of total CO sub(2) and super(14)CO sub(2) production, as well as the large number of samples that can be accommodated make this instrument ideal for the execution of the large screening studies needed to obtain reliable estimates of the spatial variability of rates of pesticide degradation.

Three full generations and at least a partial fourth generation of the GBM occur in Missouri. Field testing established that the GBM pheromone incorporated into rubber septa was quite stable. The following treatments did not change effectiveness of such septa for collecting GBM: (1) aging in the field for 10 weeks, (2) refrigerating for 2 years and (3) fresh. Most moths were caught in traps located around the periphery of the vineyard. GBM population dynamics were asynchronous among locations suggesting monitoring programs should be tailored to specific vineyards when implementing pest management programs.

AN - 15417696; 2157861 AB - An outbreak of pine bark beetles (Coleoptera: Scolytidae) occurred in the central highlands of the Dominican Republic during 1986-1987. Initiation of the outbreak coincided with a period of severe drought. Thousands of native West Indian pines, Pinus occidentalis Sw., were killed by beetles attaching the trunk and branches. Ips calligraphus (Germar) was the principal mortality agent. Two other bark beetles infested the smaller branches (Pityophthorus antillicus Bright) and shoots (Pityophthorus pinavorus Bright). Spatial attack pattern, harem size, egg gallery length, egg density, and sex ratio of Dominican I. calligraphus populations were similar to values reported from the southeastern United States. However optimal pheromone blends differed between the two populations. JF - Florida Entomologist AU - Haack, R A AU - Billings, R F AU - Richter, A M AD - USDA Forest Serv., North Central Forest Exp.

AN - 15409734; 2157639 AB - Damage to oilseed sunflower by red-winged blackbirds (Agelaius phoeniceus ) can be severe. One promising means to reduce this damage is to develop bird resistant varieties of sunflower. We report field, outdoor aviary, and laboratory assessments of red-winged blackbird preference for 2 sunflower varieties: Jacques Discovery (JD, a commercial oilseed cultivar), and Neagra de Cluj (NdC, an experimental bird resistant cultivar) at 6 dates during the course of seed development. Field results showed that red-winged blackbirds preferred JD to NdC, although NdC was eaten when JD became unavailable. Aviary and laboratory findings were consistent with these data. Observed preferences for JD may reflect the relatively high oil content of this variety. Conversely, low consumption of NdC may result from levels of anthocyanins present in the seed hulls. Varietal resistance may represent a viable approach for the control of bird depredations in sunflowers. However, the influence of oil and anthocyanin levels and morphological characteristics require further clarification.

Total percentage of parasitism was not changed because of the disruption treatment. In treated areas, however, abundance of the most numerous moth parasite, Glypta zozanae Walley and Barron, was reduced significantly below check plantation levels. In contrast, abundance of the pupal parasite Mastrus aciculatus (Provancher) was higher in pheromone-disrupted areas.

AN - 15409553; 2157657 AB - The distribution and number of eggs deposited by the tachinid parasitoid Palexorista laxa (Curran) on instars of Heliothis zea (Boddie) were studied. Significantly more eggs were deposited on the thoracic segments of instars 2-5 than on the head or abdominal segments. This may be an adaptation by the parasitoid to avoid removal of the eggs by the host's mandibles. This selectivity of egg placement was not observed on first instars or prepupae. Significantly more eggs were deposited on fourth instars than on any other host developmental stage suggesting that this may be the preferred host stage for parasitization.

AN - 15408394; 2158013 AB - At present, 12 states have a total of 23 timber severance tax programs. These programs differ greatly regarding entities subject to taxation, methods and rates of taxation, reporting and payment intervals, authorized exemptions, and guidelines for revenue usage. The historical rationale for imposing taxes of this type was that they would discourage undue or wasteful cutting and provide a mechanism whereby society could be compensated by those who benefited from the exploitation of an essentially free gift of nature - i.e., virgin, old-growth timber. More recently, however, as cutting has become increasingly concentrated in second and third growth stands, this rationale has tended to change.

AN - 15408327; 2157970 AB - The abundance of Lyonetia speculella Clemens larvae on each tree of a 1.25-ha apple orchard, planted in 1986, was determined monthly from June to September 1986 and May to September 1987. In both years, the abundance of L. speculella was low initially, increased in early summer, remained constant through midsummer, and increased again at the end of the summer. L. speculella abundance per tree was aggregated, but the distribution of infested trees was initially random, then regular for the remainder of each year. The initial increase in abundance was caused by an increase in the percentage of the trees infested and the late summer increase by an increase in aggregation on infested trees. Random, systematic, random cluster, and systematic cluster sampling designs were all equally effective in simulated sampling from the field data.

AN - 15408063; 2155566 AB - A wasp (Orasema sp.) parasitic on the fire ant, Solenopsis invicta Buren, develops to the adult stage within the ant colony, where wasp larvae are ectoparasitic on ant pupae. This phase of the parasite's life cycle requires a mechanism of integration into the host colony. Gas chromatographic profiles of hexane soaks of various stages of the parasite and host suggest that during development within the ant colony the parasite acquires the colony odor of the host through a passive mechanism, based on simple contact and other social interactions. No parasite-specific components were observed. After leaving the host nest as adults, the parasite biosynthesizes a parasite-specific cuticular compound, while retaining residual amounts of the host acquired components.

AN - 15407991; 2157264 AB - The wing trap, although economical and commercially available, has never been seriously considered as a standard for monitoring populations of the corn earworm (CEW)/cotton bollworm, Heliothis zea (Boddie), mainly because it is considered inefficient relative to other available traps. Attempts were made to enhance the performance of the Pherocon 1C (P-1C) wing trap by modifying its structure and by varying the placement of the pheromone within the trap. P-1C traps receiving 40-50 g of supplemental adhesive captured 5.1-fold more CEW males than did the P-1C standard. The introduction of horizontal barriers of either Lexan or hardware cloth across the center of the P-1C trap or the placement of Lexan strips to close side trap opening had no effect on the number of CEW males captured. Traps with the pheromone located 1.0-1.5 cm form the top center of the trap captured more males than did traps with the pheromone placed an equivalent distance from the bottom of the trap.

The panels were then exposed outdoors for 7 years in Wisconsin, Mississippi, and Washington State. Panel edges did not delaminate to any marked degree. Surface weathering occurred to varying degrees depending on the exposure, finishing system, and number of coasts of stain or paint topcoat. Panels finished with latex primer and paint generally showed best weather resistance, followed by alkyd-primed latex-painted panels. Painted panels (primed with either latex or alkyd primer) in vertical exposure generally showed good weather resistance, particularly if finished with two topcoats of paint.

AN - 15407583; 2158066 AB - In a nondiapause culture of cereal leaf beetles, Oulema melanopus (Coleoptera: Chrysomelidae), females ovipositing within 20 days after emergence were considered nondiapause. However, sexually active males in the same generation could be nondiapause or prediapause. Changes in the nondiapause incidence were compared between progenies from > 15 day old males that were feeding actively and photopositive (considered "nondiapause" males) and progenies from younger males (nonselected males). Nondiapause females increased by 19% (n = 35 generation) and decreased 22% (n = 31 generations) in the progenies of "nondiapause" and nonselected males, respectively, suggesting that nondiapause males were selected in the former group, but prediapause males in the latter group substantially decreased nondiapause.

AN - 15406680; 2157047 AB - The phytophagous arthropod community on apple was studied in Virginia, West Virginia, Pennsylvania, and New York in 1983 and 1984. Managed, "organic" (reduced management), and abandoned orchards were sampled and the arthropod communities therein were compared to examine the effects of orchard management on the community. Communities were dominated by r-selected species in managed orchards and K-selected species in abandoned orchards. Community structure is hypothesized to be regulated by human-induced, environmental factors in managed orchards and by natural enemies in abandoned orchards.

Three methods of estimating stable fly populations (from leg counts on cattle, a stanchioned-calf technique, and Alsynite fiber glass traps) were compared at three times of day. Time of sampling significantly affected population estimates in 2 of the 3 years of the study. The correlation between sampling methods was determined for each sampling time and is discussed.

AN - 15404304; 2140491 AB - Food consumption by healthy fifth-instar gypsy moths, Lymantria dispar , and larvae infected with Entomophaga maimaiga was compared. Infected larvae ate less food than healthy larvae during the two days before death. Weight gain of infected larvae was less than weight gain of healthy larvae from 3 d after inoculation. Although death of infected larvae was hastened by starvation, E. maimaiga was able to develop successfully in larvae that received no food after infection, suggesting that larval feeding during the associated period of incubation is not necessary for fungal development.

AN - 15403268; 2137992 AB - In a 0 multiplied by 2-ha flight pen, flocks of twenty brown-headed cowbirds (Molothrus ater Boddaert) and twelve red-winged blackbirds (Agelaius phoeniceus L.) were observed as they foraged on plots sown with rice seed, 0%, 50% or 100% of which was treated with methiocarb. Seed removal by birds in plots with the 50% and 100% treatments was 95%-98% less than that in the 0% groups. Seed handling behaviour did not differ among treatments for either species. These results are consistent with previous experimental findings and with theoretical models of automimicry that predict substantial protection to the entire prey population even when only a small proportion of the prey is unpalatable. Cost-benefit analysis suggests that partial repellent treatment for protection from bird damage, in addition to being environmentally sound, is economically viable in many crops.

AN - 15401337; 2145302 AB - A simple input-output model was constructed to evaluate the long-term net nitrogen (N) gain or loss or N self-sufficiency of several silvicultural systems. In general, short-rotation, whole-tree-harvest systems are not self-sufficient in N. If they include an active biological nitrogen fixation (N sub(2)-fixation) component, however, they are highly N self-sufficient even when they sustain large losses of N in harvested biomass. Forestry systems, with or without substantial N sub(2) fixation, appear to be greatly superior in this respect to most annual agricultural crops with or without N sub(2) fixation. All N inputs and outputs must be measured in field experiments, however, before N self-sufficiency can be accurately evaluated. Better estimates of loss through harvest removal, and gain through N sub(2) fixation and atmospheric inputs, over more than one rotation are particularly needed.

In vitro-based biotechnologies may have more applicability to long-lived woody plants such as forest trees, compared to agronomic crops, because of difficulties in breeding to achieve genetic improvements. Although this review is about forest trees, it applies to other species that are related by their natures of being difficult-to-propagate, e.g., many horticultural species, palms, and certain agronomic crop species such as cereals and soybean.

AN - 15396477; 2146076 AB - Growth and development of cotton fibers in a developmental mutant, Ligon-lintless, and its near isogenic wild type, Texas Marker-1, were compared in ovule and cell suspension cultures. In both organ and cell cultures the pattern of growth of fiber cells from the two genotypes mimicked the pattern of in vivo growth. The timing of fiber cell initiation soon after anthesis in Ligon-lintless suggests that the fiber cells on this mutant are analogous to the commercially important lint fibers. Length distributions of elongated cells from cell suspension culture of Ligon-lintless and Texas Marker-1 indicate that the length attained in culture is affected by the genotype of the explant tissue.

AN - 15393079; 2140983 AB - The daily CO sub(2) flux of above-ground and below-ground components of Panicum coloratum) growing in the northern Chihuahuan desert was determined during a spring drought and following the autumn reproductive phase of growth. The objectives were (i) to determine the whole-plant carbon balance after a fifty-two-day drought when photosynthetic capacity was severely repressed, and (ii) to determine the whole-plant carbon balance during favourable soil-water conditions prevalent after the autumn reproductive period. Water stress severely repressed diurnal photosynthetic capacity during drought. The below-ground biomass, however, consisted of suberized roots with low respiratory activity. The net result was a positive whole-plant carbon gain of 2 multiplied by 6 mg C g dry wt super(-1) day super(-1). Precipitation, amounting to 1 multiplied by 12 cm, ended the fifty-two-day drought, and increased the whole-plant carbon gain approximately six-fold.

AN - 15392980; 2144212 AB - A vertically arranged (8.9 by 7.6 cm) wall-mounted trap made of layered, corrugated paper was designed for use in USDA, Animal and Plant Health Inspection Service, Plant Protection and Quarantine detection programs for Trogoderma granarium Everts (khapra beetle). The trap uses a membrane or septa pheromone lure for adult males and wheat germ oil as a larval food attractant. The placement of the pheromone lure directly over a plastic collection tray containing the oil resulted in increased efficiency. Fresh oils of oat, pumpkin seed, and sesame were more attractive to larvae than wheat germ oil, but they became less attractive as the oils aged. The trap caught 3.5 times more larvae in 5 d and 4.9 times more males in 1 d compared with a commercial flat-type trap.

AN - 15392626; 2141761 AB - Seedlings of four wheat cultivars were infested with virulent and avirulent Hessian fly, Mayetiola destructor (Say), biotypes. The presence of a single virulent larva resulted in an alteration of resistance in the plant, allowing survival of all normally avirulent larvae that concurrently or subsequently infested the plant. This phenomenon makes possible the genetic loading of a fly population with potentially large numbers of avirulence genes and could, in part, account for the durability of resistance genes following the release of fly-resistant wheat germ plasm in agricultural systems. Previous infestation with avirulent larvae did not affect the plants' susceptibility to subsequent infestation by virulent biotypes.

Insect captures and laboratory-measured release rates and residual contents showed that the cotton wick dispensers, which were formerly used for 2 g liquid TML (density = 1.0 g/ml), were generally ineffective after 2-4 wk of field exposure; a 4-g dose of TML increased the longevity, but not the initial biological activity of the cotton wick. Two controlled-release formulations, a polymeric plug (70% by weight TML) and a plastic laminate, extended the effective lifetime of 2 g TML to about 8 wk. A polymeric plug with 4 g TML further extended the duration of effectiveness to 12 wk or longer.

Predators of Heliothis also are found in this habitat; they include species of spiders and ground beetles. Test plots of two species of grasses, planted with and without ammonia nitrate applications at planting, and both planted in combination with six species of legumes (total of 16 treatments), were established along U.S. Highway 61 in Washington County, Mississippi in the fall of 1984. The effect of the treatments on spiders and ground beetles during March, April and May 1985 was determined by sampling populations of these predators with pitfall traps. Treatments differed little in species diversity or in species dominance for these two groups of predators.

AN - 15391010; 2141717 AB - The extent to which the relationship between environmental factors (temperature and grain moisture content) and life history traits can predict insect population trends in stored wheat was investigated by comparing nine measured population trends with predictions from population dynamics simulation models. Regression of measured against predicted insect population densities indicated that the predictions of the simulation model explained 87, 93, and 96% of the changes in the mean measured densities of Cryptolestes ferrugineus (Stephens), Rhyzopertha dominica F., and Tribolium castaneum (Herbst), respectively.

AN - 15390997; 2141719 AB - Exposure of shortleaf and loblolly pine lateral roots to oxygen concentrations of 0-0.25 mg/L for durations of 6-24 hr before inoculation increased root susceptibility to infection by Phytophthora cinnamomi as compared with roots maintained continuously under oxygen concentrations of 7 mg/L. Symptom development in lateral roots progressed more rapidly in roots that had been stressed with low oxygen than in roots maintained under high oxygen. Maintenance of pine seedlings at oxygen concentrations of 0.25-1.0 mg/L for 12 and 24 hr before inoculation had no subsequent effect on root susceptibility to infection or the rate of symptom development in infected roots of either pine species. Results suggest that essentially anaerobic conditions are necessary in the rhizosphere before pine root tips are predisposed to attack by P. cinnamomi .

Graft inoculations of Bing trees on Colt (P. avium x P. pseudocerasus ) rootstock produced chronic X-disease symptoms consisting of small leaves and small fruit with short pedicels, but no union aberration.

AN - 15389758; 2141756 AB - Lasioseius berlesei (Oudemans), Lasioseius youcefi Athias-Henriot, Lasioseius kinikinik n.sp., and Lasioseius confusus Evans were collected from grassland soils in Colorado. Lasioseius berlesei and L. youcefi are known only from the female, and for the first time in an ascid mite, the authors experimentally demonstrate that they reproduce by thelytokous parthenogenesis. Both species are omnivores that will feed on fungi and animal prey, and they share a multidenticulate ridge apposed to a groove on the paraxial faces of the chelicerae which appears to function as a mashing and filtering mechanism during mycophagy. Similar cheliceral structures are lacking in L. kinikinik n.sp. (described in this paper), a bisexual species that must mate to produce eggs, and does not feed on fungi. Diagnoses are presented for L. berlesei, L. youcefi , and L. confusus , and their sperm reception structures (spermatheca, etc.) are illustrated for the first time. JF - CAN. J. ZOOL./J. CAN. ZOOL.

In the new system, race designations are assigned according to the resistance genes that their virulence matches, i.e., according to their virulence formulae. Thus, isolates currently designated Race 1 become Race 0 in the new system, indicating their lack of virulence on corn with any of the Ht genes. Current Race 2 becomes Race 1 to indicate its virulence to Htl , and current Race 3 and Race 4 become Race 23 and Race 23N, respectively. Representatives of Race 0 (ATCC 64837), Race 23 (ATCC 64836), and Race 23N (ATCC 64834) have been deposited in the American Type Culture Collection under their old race designations.

AN - 15385115; 2127469 AB - Interactions between Enterobacter cloacae and Rhizopus stolonifer were evaluated to determine possible mechanisms by which E. cloacae protects peach fruit from postharvest rot caused by R. stolonifer . Inhibition of Rhizopus sporangiospore germination by E. cloacae was dependent on the concentration of the antagonist. Antagonist concentration (1 x 10 super(10) cfu multiplied by mL super(-1)) needed to completely inhibit germination was similar to that needed to prevent fruit infection. Significant inhibition of in vitro hyphal growth was achieve d at 1 x 10 super(5) cfu multiplied by mL super(-1) with simultaneous culturing of the fungus and antagonist. A reduction in inhibition occurred when addition of the antagonist was delayed. The presence of glucose in the growth medium did not prevent attachment of E. cloacae to hyphae and sporangiospores of R. stolonifer . Agglutination assays of sporangiospores by E. cloacae were positive whereas agglutination of cell-wall fragments was less distinct. Data indicate that nutrient competition, perhaps facilitated by bacterial attachment, may play a key role in E. cloacae and R. stolonifer interactions. JF - CAN. J. BOT./J. CAN. BOT.

Observations of moths with night vision-amplifying goggles verified the high attractiveness of the pheromone lure and revealed sustained direct lure contact by male moths. The IPS trap appeared to be most suitable to integrated pest management programs because of its high catch, economy, ease of service and transport, and apparent durability.

Larvae were most susceptible to the Mexican strain, less susceptible to the Agriotos and Breton strains, and least susceptible to the All strain. The Mexican strain was 22 times more virulent than the All strain. Rootworm larvae encapsulated invading nematodes of all strains, but the frequency of encapsulation was lower for the Mexican and Agriotos strains.

AN - 15380587; 2126530 AB - Variability of adult grasshoppers counts was studied for statewide collections made in Montana during 1987. Geostatistical techniques were used to compare the spatial relationships among counts from three recognized environmental regions. Related geostatistical methods also were used to develop macroscale (regional) grasshopper hazard maps based on spatial variability. Development of semivariograms and kriging (an interpolation method) for grasshopper count data are discussed, as well as potential for the applications of such methods for use in pest management. Results and methods will be useful to insect ecologists and pest managers interested in developing hazard maps and understanding the spatial relatedness of rangeland grasshopper populations.

AN - 15380408; 2126444 AB - The time of response of pink bollworm, Pectinophora gossypiella (Saunders), to gossyplure-baited traps (1:1 ratio of Z,Z and Z,E isomers of 7,11-hexadecadienyl acetate) was studied throughout the cotton growing season near Phoenix, Ariz. First capture means were 2213 hours (early season), 0108 hours (midseason), and 1726 hours (late season) (all times are given for Mountain Time). Similar relationships were observed in the time of peak and last capture means through the season except that they occurred later in the night. Temperature affected the time of capture; higher temperatures resulted in later captures and lower temperatures resulted in earlier captures. Regression models showed that the time of capture was predictable with the independent variables, time of sunset and temperature, accounting for 88 to 95% of the variation in time of capture.

AN - 15378326; 2128245 AB - The influence of leaf detachment and leaf storage conditions on survival of Liriomyza trifolii (Burgess) eggs, larvae, and reared pupae was studied. When kept at 26 plus or minus 1 degree C and at approximately 100% relative humidity (RH) so that leaf fresh weight and turgidity were maintained, chrysanthemum (Dendranthema grandiflora Tzvelev. cv. Iceberg) leaves that were detached immediately after oviposition yielded as many leafminers as did leaves left on plants. Detached foliage kept at 26 degree C but at a lower and fluctuating relative humidity (80 plus or minus 20%) did not yield leafminers if harvested immediately after oviposition. If, however, leaves were detached two days after oviposition (first instars present) and stored at 26 plus or minus 1 degree C and approximately 80% RH, the leafminer yield was comparable to that from undetached leaves.

Three sites were in uncut forest and one was in a permanent shrubfield. The remaining 47 had been logged one to several times in the previous 10 years. Mean BSR in "unforested" sites was 7.6 for 1978 and 1979, combined; that in "forested" sites was 20.1. On 6-ha subplots in the forested sites, BSR averaged 16.7 breeding species in 1978 and 16.5 in 1979. Total crown volume was the best single predictor of BSR in each year separately and in the pooled data set for both years. Total crown volume accounted for 76% of the variance in BSR in the pooled data. JF - Auk AU - Verner, J AU - Larson, T A AD - USDA Forest Serv., Pacific Southwest Forest and Range Exp.

Four weeks after initial P. haemolytica exposure, calves were exposed to infectious bovine rhinotracheitis virus and became clinically ill. Four calves were induced to shed P. haemolytica from both nostrils by the virus infection; thus, they were harboring the bacterium and were susceptible to active recolonization. Four calves were not induced to shed P. haemolytica .

AN - 15376696; 2127606 AB - The inheritance of resistance to culture 7434-1-IT of Puccinia recondita f. sp. tritici was examined in four triticales that were selected as potential sources of resistance genes for wheat. The resistant triticales were each crossed to the susceptible triticale PI 429007. The parents and the F sub(1), F sub(2), and F sub(3) progeny were evaluated for segregation of infection type (IT) to determine the number and dominance of genes for resistant IT that each cultivar possesses. The resistant cultivars were crossed to each other and the F sub(2) and F sub(3) progeny were evaluated to examine the relationships of the resistance genes. The F sub(3) progeny with susceptible IT derived from the resistant X susceptible crosses were evaluated for the presence of genes for long latent period, an important component of slow-rusting resistance. PI 429120 possesses two independent, incompletely dominant genes that together confer a 0; n IT in the adult plant, PI 429155 possesses one incompletely dominant gene that confers a 12c IT. PI429121 expresses a 0; In IT, and PI 429215 expresses a 0; n IT. Both cultivars possess one incompletely dominant gene with a major effect and an additional minor gene that confers a nearly susceptible, mesothetic IT.

The methods employed are based on one-dimensional turbulent diffusivities and use numerical solutions to the steady-state diffusion equation. The model formulates stomatal response as a function of vapor pressure deficit and the within-canopy profile of mean photosynthetically-active radiation (PAR). It is then used to assess the influence that foliage structure, density, and sheltering can have upon the bulk transfer coefficient, kB sub(v)- super(1) and the canopy resistance.

Biomass, and chlorophyll-a and carotenoid contents decreased with increasing fluridone concentration. No change was observed in C-phycocyanin content. Within the lipophilic pigment fraction, decreases in the relative abundances of individual carotenoids caused corresponding increases in the relative abundance of chlorophyll-a. The light-limited slope, the photosynthetic maximum, and the irradiance value at onset of light saturation decreased with increasing fluoridone concentration. Inhibition of growth and chlorophyll content was attributed to the photo-oxidation of chlorophyll molecules. Inhibition of the photosynthetic efficiency and maximum was attributed to reduced carotenoid content. JF - Journal of Phycology AU - Millie, D F AU - Greene, DA AD - Southern Reg. Res.

Second and third instars feed in male and female pine flowers during early May. Fourth and fifth instars tunnel in second-year cones for about 2-3 wk between mid-May and mid-June and often require two cones to complete development. Larvae pupate within cones during June, and adults are active from mid-June to late July. At 26 degree C, eggs hatch in 6-9 d.

AN - 15376063; 2129386 AB - Fluorescence spectrophotometry was used to assess the possible use of pteridines in the compound eyes to estimate the age of adult screwworms, Cochliomyia hominivorax (Coquerel). Factors affecting the quantities of pteridines include temperature and head size. No difference in pteridine levels was found among flies fed protein or carbohydrate. A regression model for estimating the age of female screwworms was constructed. The model uses head capsule size and relative pteridine quantities and assumes a constant body temperature of 30 degree C. This regression formula has an r super(2) of 0.74. The authors study extends the use of pteridine accumulation for age determination from obligate sanguinivorous Diptera to an autogenous species that feeds facultatively on nectar and wound exudates. The technique appears to provide a valid means to determine age of these flies. JF - Journal of Economic Entomology AU - Thomas, D B AU - Chen, A C AD - Screwworm Res.

AN - 15374767; 2129276 AB - Diapetimorpha introita (Cresson) occurred from May to November and was the primary parasitoid of fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), pupae in corn fields at Tifton, GA, from 1983 to 1985. Another previously unreported pupal parasitoid of FAW, Cryptus albitarsis (Cresson), occurred only during a single sample conducted in November 1984. Predation was the primary mortality factor, averaging 44.7, 37.8, and 95.8%, respectively, during 1983, 1984, and 1985. These studies indicate parasitoids and predators of FAW pupae play a primary role in regulating FAW populations following their development in corn and likely significantly reduce the numbers that subsequently disperse into new habitats for oviposition on other crops.

AN - 15373958; 2121423 AB - A needle cast disease caused by Lophodermium seditiosum has killed or severely damaged millions of red and Scotch pine seedlings in nurseries and Christmas tree plantations in many areas of the United States since the mid-1960s. Outbreaks of L. seditiosum periodically occur in nurseries when chemical control measures are not used or improperly applied. The impact of this disease on seedling height and diameter growth of three species grown in a Wisconsin nursery was studied. Pine seedlings were either protected with fungicides or left unprotected for 3 yr. In the nursery, seedling survival and height and diameter growth were significantly less in untreated than in treated plots. One year after outplanting, red pine seedling survival and height growth were not significantly different, but symptoms of Lophodermium needle cast were visible on 80% of the foliage of untreated seedlings and on only 20% of maneb-treated seedlings.

AN - 15373500; 2125219 AB - Watermelon cultivars differentially resistant to Fusarium wilt were preinoculated (induced) with Fusarium oxysporum f. sp. cucumerinum or avirulent races of F. o. niveum 24 or 72 hr prior to challenge with a virulent race of E. o. niveum . All of the inducer treatments significantly reduced wilt symptoms. Avirulent races of E. o. niveum induced a higher level of resistance than did F. o. cucumerinum . An interval of 24 hr between induction and challenge provided significant protection; a 72-hr interval further enhanced resistance. When roots of the wilt-susceptible watermelon cultivar Black Diamond were induced with E. o. cucumerinum and the leaves inoculated with Colletotrichum lagenarium 24 or 72 hr later, 50% fewer lesions developed on leaves of induced plants than on noninduced inoculated controls. This suggests that induced resistance to F. o. niveum is both local and systemic, as well as nonspecific. JF - Phytopathology AU - Biles, CL AU - Martyn, R D AD - USDA, ARS Appalachian Fruit Res.

Females developed on shoots and males developed on needles of loblolly pine, Pinus taeda L. Generations overlapped and crawlers were most abundant in May, mid-July to early August, and late October to early November. The average fecundity was 1865 crawlers per female. Parasitism averaged ca. 15%, but the predation rate reached 50%. Coccophagus lycimnia Walker (Hymenoptera: Aphelinidae) was the most common parasitoid reared from both males and females. A pyralid larva, Laetilia coccidivora (Comstock), was a frequent predator of females.

AN - 15371531; 2124945 AB - Survival of Ascochyta fabae f. sp. lentis in naturally infected lentil (Lens culinaris ) seed was studied over 4 yr at temperatures of 20, 5, -18, and -160 to -196 C (liquid nitrogen). The pathogen was isolated from 52 to 78% of the infected seeds during the experiment. There was an 18-25% increase in the incidence of seedborne A. f . f. sp. lentis between the third and fourth years at all temperatures. Incubation of infected seeds for 4 yr at 20 to -196 C did not adversely affect the pathogenicity of the fungus to lentil. Germination of infected seeds was appreciably lower than that of healthy seeds at all temperatures on each sampling date (1 day, 1, 2, 3, and 4 yr). These was a significant reduction in germination of infected, but not of healthy, seeds at each temperature over the 4-yr period.

AN - 15371413; 2120071 AB - Almost 40% of the world's land area is comprised of arid and semiarid regions that are inhabited by some 700 million people; approximately 60% of these drylands are in developing countries. Although these regions will continue to produce most of the world's food grains for expanding populations in the years ahead, the yields are extremely low. The key to improving the productivity, stability, and sustainability of these dryland farming systems is to halt any further deterioration of the soil resource.

AN - 15371403; 2120280 AB - Humus may account for 1 to 2% or less of the surface horizon in arid soils; however, it is still a very important fraction with many beneficial properties. Decomposition of fresh organic residues is discussed in terms of the fate of their constituent carbons. Before residues can be considered part of the true soil humus, they undergo profound transformations and no longer resemble the original material. Important factors influencing the degradation and stabilization of organic residues in soil are examined, along with information on the characterization of soil humic acids and polysaccharides that has a accumulated through the use of various degradative and spectral procedures.

AN - 15363568; 2119213 AB - Triploid grass carp Ctenopharyngodon idella were presented with three aquatic plant species (sago pondweed Potamogeton pectinatus , Eurasian watermilfoil Myriophyllum spicatum , and American pondweed P. nodosus ) in outdoor canals with static and flowing water in winter, spring, and summer. Plant consumption by triploid grass carp in winter was low but increased dramatically in spring and summer. Plants of all three species produced longer shoots in canals with flowing water than with static water. The differences in short length may have altered the triploid grass carp's consumption rate and preference. Flowing conditions also had varying effects on nutritional content of plants. None of the variables of the proximate analysis of plants correlated statistically with preference. This suggests that accessibility and ease of mastication were more important than nutritional quality of the plants. Algae consumption by triploid grass carp, however, made it difficult to discern correlations between nutritional factors and vascular plant consumption.

However, these models remain virtually unused outside the research environment because resource agencies/managers do not have the expertise required to use these models effectively. New concepts and techniques developed in the field of artificial intelligence (AI) offer the opportunity to develop expert system computer programs to assist resources managers in using complex models that simulate natural resource systems. Development is in progress on an expert system (EXSPUR) to aid in the use of an existing rangeland simulation model (SPUR).

AN - 15358941; 2120437 AB - A primary concern in applying existing 0 sub(3)-effects data on crop production is the relatively unknown influence of soil moisture, which may modify plant response to O sub(3). One deficiency in field experiments that have tested the influence of soil moisture on crop response to 0 sub(3) has been lack of control of soil moisture conditions in open-top chamber plots. Most experiments have relied on the occurrence of normal drought periods during the growing season and use of irrigation to adjust soil moisture conditions. This has not allowed the control of the water stress cycles that is desirable. In 1986 a field experiment was performed with soybean (Glycine max). (L.) Merr. cv.

The mixed culture produces exoenzymes functional up to 65 degree C in the presence of salts. Degradation products include the pyruvic acetal of mannose and branched oligosaccharides derived from cleavage of main-chain beta -(1 arrow right 4)-D-glucosyl linkages. Release of the terminal pyruvic acetal of D-mannose leads to oligosaccharide products that evidently contain the ene-4,5-unsaturated glucuronic acid residue.

AN - 15354449; 2102151 AB - Nonspecific serum plate agglutination reactions to some avian mycoplasma antigens were induced by injecting chickens with several commercial poultry disease vaccines. All of the vaccines were inactivated, and most of them had oil-emulsion adjuvants. The serum plate agglutination reactions appeared within 2 to 3 weeks post-vaccination and generally persisted for several weeks. The plate test reactions were noted with both Mycoplasma gallisepticum (MG) and M. synoviae (MS) antigens, although the degree and duration of the reactions varied with the vaccine involved and the source of MG and MS plate test antigens. Attempts to prevent the nonspecific reactions by heat-inactivation at 56 C for 30 minutes or by addition of equal volumes of solutions of 2-mercaptoethanol, dithiothreitol, or 3 M sodium chloride were ineffective. No hemagglutination-inhibition activity against MG or MS antigens was induced by the vaccines. JF - Avian Diseases AU - Yoder, HW Jr AD - USDA, ARS, Southeast Poult. Res.

Seventy-five urine samples were collected from pregnant cows challenge exposed with type hardjo-bovis. Twenty samples were collected from steers not exposed to hardjo-bovis. Sediments were examined, using fluorescent antibodies and a repetitive sequence element nucleic acid probe, to detect leptospires. Urine samples were processed for bacteriologic culture, using standard techniques. Under laboratory conditions typically used, leptospires were detected in 60 of 75 urine samples from challenge exposed cows by nucleic acid hybridization, in 24 samples by fluorescent antibody test, and in 13 samples by bacteriologic culture.

(2) Measuring instruments widely used in the field are precise. (3) Sampling techniques are comparable. (4) Investigator influence, for single and cooperative banders, is minimal even when small samples are compared. Seasonal and daily variation within the data did appear, however, and were attributed to seasonal fluctuations of food resources, feather wear, breeding activities, and the added mass of ingested food.

AN - 15344550; 2106152 AB - Russian wheat aphids survived on 47 of 48 cool-season grass species, 18 of 32 warm-season grass species, and none of the 27 legumes or 17 forbs. Jointed goatgrass (Triticum cylindricum (Host) Ces.) was the most suitable host, followed by barley, European dunegrass (Elymus arenarius L.), and little barley (Hordeum pusillum Nutt.). Russian wheat aphids survived equally well on several cool-season grass species as they did on wheat. Compared with wheat, warm-season grass species were poor hosts for Russian wheat aphids. Many cool-season grasses were as preferred as the most favored warm-season grass species. The importance of Russian wheat aphids in North America has increased because they can survive on a broad range of cool- and warm-season grasses that grow throughout areas that produce barley and wheat.

Although in vitro studies have shown that C. pylori is suscpetible to most commonly used antibiotics, predictions from in vitro sensitivity studies have not led to a safe and generally effective therapy; C. pylori has proved to be very difficult to eradicate in vivo. The authors used the urea breath test to assess the susceptibility of C. pylori in vivo to various drugs. C. pylori was susceptible to bismuth subsalicylate, bismuth subnitrate, and furazolidone. C. pylori was not susceptible (i.e., urease activity remained despite administration of the drug) to the following drugs, antiulcer agents, NSAIDS, antibiotics, salts and miscellaneous.

AN - 15335613; 2094298 AB - This study investigated the possibility of using aerial color infrared (CIR) photography as a survey technique for egg populations of Psorophora columbiae within a riceland agroecosystem. To accomplish this, eight photographic missions were flown over study fields during a variety of seasons and at various altitudes. Assessment of resulting photographic data indicates features reported in the literature as being attractive for oviposition by Ps. columbiae (i.e., rice field levees, tire tracks, ditches and low areas) can be readily detected on aerial CIR photographs. Features associated with Ps. columbiae oviposition sites were easily visible on photographs at scales as small as 1:42,000.

AN - 15334827; 2091015 AB - Design of REPASS included a forward air intake to avoid sampling of turbulent air, an aspirated spore trap, stable flight, and simple construction. Specifications were as follows: length, 150 cm; wingspan, 183 cm; weight, 4.5 kg; power, 10 cc engine and airspeed, 25-85 km/h. A vacuum motor pulled air over 1-12 plastic rods at 0.106 m super(3)/min. Single rods were seasonally exposed for 1 min at five altitudes to 62 m above ground over 97 ha of 1- to 2-year-old cottonwood near Fitler, MS. Fungus spore genera and quantity varied with altitude above ground and collection date. Spores of the genera Bispora, Cercospora, Epicoccum, Helminthosporium), Melampsora, Monilochaetes, Trichothecium and 12 other identified and some unidentified fungi were trapped during June to November. Total numbers of spores decreased as altitude increased. Spore genera decreased during November to May. A few Bipolaris sp. spores were collected in January. Urediospores of Melampsora medusae Thuem, were not trapped over 50 m above ground, after leaf fall, or in the spring. REPASS can meter spore density over crop trees within visual range of the operator. JF - CAN. J. BOT./J. CAN. BOT. AU - McCracken, F I AD - USDA For. Serv., P.O.

AN - 15332855; 2091671 AB - On soybean leaves at 20 C in the dark, uredospores of Phakopsora pachyrhizi began germinating 1.5 hr after dew was provided and reached a maximum level after 6-7 hr. Susceptible soybeans inoculated with viable uredospores developed no rust at dew periods less than 6 hr. At 6 hr, trace levels of primary rust lesions developed at 18, 20, 23, and 26.5 C. After 8 hr of dew at 18-26.5 C, lesion intensities were 10-fold higher than those at 6 hr at the corresponding temperatures. Increasing dew duration from 12 to 16 hr resulted in no significant increase in rust intensity, even at the most favorable temperatures (18-26.5 C). No lesions developed at 9 and 28.5 C, even with dew periods as long as 20 hr. Uredospores on unwetted soybean leaves progressively lost infectivity during sunshine conditions, but exhibited enhanced infectivity during 1 or 2 days on dry foliage under cloudy conditions.

Five barrows (7 weeks old at beginning of study) per group were fed either control feed, 2.0 mg of aflatoxin (AF)/kg of feed, 2.0 mg of ochratoxin (OA)/kg of feed, or 2.0 mg of AF and 2.0 mg of OA/kg of feed for 28 days. Production performance, serum biochemical, hematologic, and pathologic evaluations were made. Body weights were reduced by the combination treatment, whereas body weight gain was decreased by all toxin treatments. The effect of AF and OA in combination on body weight gain was additive. Liver weights were increased by the combination treatment, whereas kidney weights were increased only in the OA group.

AN - 15320843; 2080166 AB - Mossbauer parameters at 125 K for both the oxidized and semi-reduced states of FeMoco isolated from the MoFe protein of Azotobacter vinelandii nitrogenase of delta /Fe = 0.32 and 0.37 mm/s and Delta Eq = 0.84 and 0.71 mm/s, respectively, are reported. FeMoco(ox) fits the Debye model perfectly from 4.2 - 125 K and has a S= 0 ground state. FeMoco(ox) apparently contains 10-20% FeMoco(s-r)and vice versa, possibly as a result of the spontaneous oxidation phenomenon. Quantitation of the spectra indicates a Fe:Mo ratio of 5 plus or minus 1:1 and the similar quadrupole splittings and isomer shifts suggest a similar environment for all iron atoms.

AN - 15319755; 2077942 AB - Carbon content was measured in sediments deposited in 58 small reservoirs across the United States. Reservoirs varied from 0.2 to 4000 km super(2) in surface area. The carbon content of sediment ranged from 0.3 to 5.6 percent, with a mean of 1.9 plus or minus 1.1 percent. High variability was found in carbon content, carbon accumulation, and sediment accumulation rates due to individual watershed and reservoir characteristics rather than to any broad physiographic patterns. The carbon accumulation rates in these reservoir sediments indicate that reservoir sediments could be a significant sink for organic carbon.

AN - 15311529; 2077207 AB - The authors have isolated and sequenced an anther-specific cDNA clone and a corresponding genomic clone from tomato. The gene (LAT52) encodes an 800-nucleotide-long transcript that is detectable in pollen, anthers and at 20- to 50-fold lower levels in petals. LAT52 mRNA is not detectable in pistils, sepals or non-reproductive tissues. Steady-state levels of LAT52 mRNA are detectable in immature anthers containing pollen at the tetrad stage and increase progressively throughout microsporogenesis until anthesis (pollen shed). The gene encodes a putative protein of 18 kDa that is cysteine rich and has an N-terminal hydrophobic region with characteristics similar to eucaryotic secretory signal sequences. LAT52 is a single or low copy gene in tomato and shares homology with sequences in tobacco.

AN - 15308571; 2064554 AB - Single-teliospore cultures of Tilletia indica , causal agent of Karnal bunt of wheat, were examined by horizontal starch gel electrophoresis and staining for 50 enzymes. Thirty-two were present in high concentrations and could be resolved. Of 36 presumed isozyme loci, 15 (42%) were polymorphic (having allelic variation) among cultures. The high number of alleles in common (Rogers' coefficient of similarity = 0.83) among isolates of T. indica facilitated their differentiation from those of Tilletia barclayana , the causal agent of kernel smut of rice. Teliospores of the latter are frequently confused with those of T. indica . The average coefficient of similarity comparing T. indica with T. barclayana was extremely low (0.04), emphasizing the large difference in their isozymes. Isozymes are being used at the Foreign Disease-Weed Science Research Unit to distinguish between teliospores of T. indica and T. barclayana in stored grain, storage facilities, and transportation vehicles.

AN - 15308400; 2064616 AB - Chlorosubstitution reactions occur readily during HCl hydrolysis of delta - and epsilon -hydroxynorleucines (Hnle), the products of deamination of poly-L-lysine by nitrite at low pH. During amino acid analysis, chloronorleucines elute as new peaks after delta - and epsilon -Hnle. To determine if other hydroxyamino acids undergo similar changes during hydrolysis, they were subjected individually to HCl hydrolysis conditions with and without added phenol. Amino acid analyses indicated that terminal hydroxy groups on linear side chains undergo reactions during HCl hydrolysis; the products appear as new peaks which may be chloroderivatives.

AN - 15307608; 2074273 AB - BEEPOP is a computer model that simulates honey bee colony population dynamics. Estimates of population size and composition (i.e., proportions of workers and drones) at time (t) are based upon initial colony population size, weather conditions, reproductive potential of the queen, and forager longevity. Results of a sensitivity analysis indicate that the queen's egg-laying potential has the greatest effect on colony population size. Yearly trends in population growth and age structure generated from simulations are also discussed.

This sequence contained a single long open reading frame (ORF) starting upstream of the cloned region. The ORF was expressed as a fusion protein in Escherichia coli , and the product was detected by antibodies specific for the coat protein of BYMV. The predicted length of the coat protein gene was 822 nucleotides, corresponding to a 273 amino acid coat protein of M sub(r) 30910. The deduced amino acid sequence of the BYMV coat protein was compared to the chemically determined amino acid composition of purified virion protein, and of protein prepared from trypsin-treated virions.

AN - 15305035; 2068424 AB - Prior to the impoundment of the lower Stones River in 1968, 48 species of unionoid mussels were known from its drainage basin. Thirty-nine stations were sampled upstream from the present reservoir between April, 1980 and March, 1981. Thirty species, including two previously unreported species, were collected. Compared to historical records, these data represent a 40% decline in the river's known fauna and a 25% loss of species within the portion of the river not inundated by the reservoir. Environmental perturbations, such as water quality degradation and illegal gravel dredging, appear to be significant causal factors in the reduction of species diversity within the upper Stones River.

The frequency of visits by parasites and successful parasitism in a 2-h exposure period were high for all age classes of pupae but markedly lower for pupae. Incidence of parasitism appeared to be higher on male hosts than female hosts, but the sex ratios were similarly skewed toward females in progeny emerging from hosts of both sexes.

AN - 15289431; 2048875 AB - Larval and pupal development times and behavior of the cotton bollworm, Heliothis zea (Boddie), were studied on foliage and blooms of crimson clover, Trifolium incarnatum (L.). Larvae reared on foliage required about 8 d longer to pupate than those reared on blooms. Duration of pupal period was not affected by food source. Food source did not affect numbers of eggs laid by adult females. Larvae ate unexpanded leaf terminals, expanded canopy leaves, and buds of vegetative clover and fed almost exclusively on blooms of reproductive clover. First to third instars bored into terminals and buds when available on vegetative and reproductive plants, whereas larger third to fifth instars remained exposed as they fed.

To test the hypothesis that loss of humus from nursery soils may affect Fusarium spp survival, three nursery soils were amended with four concentrations of three organic materials high in humic content. Amendment-induced increases and occasional decreases in tree growth varied with soil origin. A humic-rich amendment that stimulated tree growth in all soils also increased the numbers of several soil microbial groups ("total" bacteria, actinomycetes, extracellular-chitinase producers and facultative anaerobes).

AN - 15286296; 2049501 AB - The maintenance of biological diversity has emerged as a primary issue in natural resource management. The best change to establish biological diversity as a land management objective is on the public lands of the United States. These public lands contain 111 of the 135 Kuechler potential natural vegetation types in the United States. It seems unlike that large-scale reservation of much more land will occur. Therefore, the real test for maintenance of biological diversity will occur on lands dedicated to multiple-use management. Conservation biologists are desperately needed to focus attention on biodiversity as a management goal, to provide information necessary to guide management, to train agency personnel in the philosophy and mechanisms of prescribing biodiversity.

AN - 15286208; 2049474 AB - Opportunities for examining gap processes at a range of spatial and temporal scales are excellent in the Pacific Northwest where extensive, uncut forests still exist and stumps on many cutover areas retain a record of previous tree ages and fire scars. Canopy disturbances are of varied types and spatial and temporal scales, and intervals between stand-replacing disturbances potentially exceed 1000 yr on many sites (Dale et al. 1986). In this essay the authors focus on coniferous forests dominated by Douglas-fir (Pseudotsuga menziesii ) and western hemlock (Tsuga heterophylla ). Their objective is to contrast the roles and importance of fine- and coarse-scale disturbances, illustrating the importance of various disturbance characteristics and system context in controlling community dynamics.

AN - 15282121; 2030020 AB - There is evidence that lipid peroxidation initiated by O super(-)d2 radicals may be involved in altered plant cell membrane permeability in a bacteria-induced hypersensitive reaction. Such alterations have also been reported for paraquat-treated plants. Likely membrane targets for lipid peroxidation are unsaturated fatty acyl groups. The authors monitored levels of different fatty acyl groups in cucumber cotyledons during paraquat treatment and during a hypersensitive reaction induced by Pseudomonas syringae) pv. pisi . Fatty acyl groups from galactolipids (a lipid found specifically in plastids) and polar lipids (found in all cell membranes) were analyzed in a total lipid extract. The authors also analyzed fatty acyl groups from polar lipids of an enriched plasma membrane fraction. The results verified that paraquat treatment reduces fatty acid unsaturation in plastid lipids. Fatty acid unsaturation decreased in the enriched plasma membrane fraction during both paraquat treatment and the hypersensitive reaction.

Seven cows were vaccinated once and 8 cows were vaccinated twice with a USDA-licensed pentavalent leptospiral vaccine. Five cows were maintained as nonvaccinated controls. Cows were bred 1 to 2 months after the last vaccination. During the 4th to 6th month of gestation, all cows were challenge exposed on 4 occasions by conjunctival instillation of 10 super(8) serovar hardjo) type hardjo-bovis organisms and on 3 occasions by conjunctival instillation of urine from a cow shedding hardjo-bovis. All control cows and 13 of 15 vaccinated cows became infected and shed leptospires in the urine. Leptospires were detected in fewer urine samples collected from vaccinated cows, compared with those collected from control cows. Four stillborn calves and 3 weak calves were born to control and vaccinated cows. Leptospires were detected in the kidneys of 11 apparently healthy calves born to vaccinated and control cows. Agglutinating antibodies were not detected in the precolostral serum of these calves.

The strains were compared on the basis of immunologic, histopathologic, and bacteriologic responses. There were 4 treatment groups for each strain of mice: vaccinated with homologous lipopolysaccharide and challenge exposed to B. abortus strain 2308; not vaccinated but challenge exposed; vaccinated but not challenge exposed; and not vaccinated and not challenge exposed. Results indicated that mice can be used for comparative studies on the pathogenesis and immunogenesis of B. abortus infections; strains of mice may vary in their responses to Brucella infection, regardless of their vaccination status. Bacteriologic and immunologic responses in mouse strains BALB/c, CD-1, C3H/HeN, and C3H/HeJ, but not those of CBA/NJ, were extrapolative among strains.

AN - 15276989; 2036077 AB - The only attractant pheromone identified for a plant-feeding heteropteran is that of the southern green stink bug Nezara viridula , a species native to the Ethiopian Region but now cosmopolitan in distribution. The pheromone released by males of this Nezara species differs somewhat between Brazilian and North American populations suggesting that pheromone strains exist for this worldwide pest. The authors now confirm that pheromone strains of N. viridula do exist and report that green stink bug males from the sister genus Acrosternum emit bouquets comprised of distinctive ratios of the same sesquiterpenes as in N. viridula .

AN - 15275512; 2036693 AB - In Florida, Meloidogyne christiei is a widespread root parasite of the turkey oak (Quercus laevis ) forming nodulelike galls, mainly by hyperplasia. Motile, vermiform juveniles infect lateral root tips at or near the apex. Upon penetration, nematodes appear to migrate through cortical parenchyma in a spiral manner to the phloem where feeding sites are initiated. Feeding sites are comprised of giant cells (hypertrophied phloem parenchyma) which contain granular cytoplasma and many unusual nuclei. Initially, the enlarged ovoid spherical multinulceolate nuclei have smooth envelopes. These nuclei elongate, aggregate, and their envelopes become lobed with age. Giant cell cytoplasm commonly aggregates along the thickened walls which contain numerous pits. JF - REV. NEMATOL. AU - Kaplan, D T AU - Koevenig, J L AD - USDA, ARS, Hortic. Res.

AN - 15275354; 2037687 AB - Colostrum-deprived lambs (10 to 20 days old) were inoculated with either ovine adenovirus type 6 (OAV-6; n = 6), Pasteurella haemolytica type A1 (n = 6), or OAV-6 followed by P. haemolytica 5 days later (n = 10). Another group (n = 3) served as sham-inoculated controls. Lambs inoculated with OAV-6 or P. haemolytica developed mild and moderate respiratory tract disease of 6 and 3 days' duration, respectively. Lambs inoculated with virus and bacteria developed clinical signs of respiratory tract disease of greater intensity and duration (9 days) than with either agent alone. Within 3 hours of bacterial inoculation, all lambs that received P. haemolytica were anorectic, listless, and febrile, and had hyperpnea and dyspnea. Ovine adenovirus type 6 was isolated from all virus-inoculated lambs. Although P. haemolytica was not recovered from all bacteria-inoculated lambs, it was recovered for a longer period in the group that received both agents. Antibody to OAV-6 was detected in virus-inoculated lambs as early as day 6 after inoculation. The control lambs remained clinically normal and neither virus nor bacteria were recovered at necropsy.

AN - 15273914; 2040991 AB - An in vitro bactericidal assay that used bovine heparinized blood was investigated for its usefulness in detecting differences in the bactericidal immunity of calves against Pasteurella haemolytica serotype 1 (Ph1). The blood bactericidal assay was used to evaluate 30 calves under typical market stress from 4 farms in eastern Tennessee. All calves had decreased bactericidal activity, as they moved into a feedyard in Texas. The bactericidal activity was reduced among sick calves, based on the severity of clinical signs. Morbidity was highest during the first 14 days in the feedlot. During this period, healthy calves had a decreased bactericidal index (BI) of 4 points, and calves with clinical signs of bovine respiratory tract disease for 3 days had a decreased BI of 8 points. The average reduction in the BI of calves with clinical signs of bovine respiratory tract disease for 6 or more days was 14 points.

AN - 15272832; 2031260 AB - The sensitivity of an indirect enzyme-linked immunosorbent assay (ELISA) for bovine IgG serum antibody to Pasteurella haemolytica was compared with that of an indirect hemagglutination (IHA) test. Pasteurella haemolytica serotypes were grown in a chemically defined cell culture medium, and soluble antigens released into the growth medium were used in the ELISA and IHA test. An ELISA with serotype-1 antigen consistently detected antibody in sera that were positive by IHA test (correlation, 99%). Sera reacting with serotype-1 ELISA antigens also reacted with ELISA antigens prepared from other serotypes. Although ELISA titers averaged 5 log sub(2) units higher than IHA titers, plots of titers determined by the 2 methods were approximately linear. Titer increases detected in paired serum samples by either test were similar. The ELISA was more sensitive than was the IHA in detecting colostral IgG antibody in serum of newborn calves. The ELISA uses a simple, stable antigen preparation and detects antibody to P. haemolytica) serotypes that commonly infect cattle.

AN - 15272683; 2033737 AB - Phylogenetic relationship is an indication of shared abilities, or at least of shared constraints, on morphology, physiology, and behavior; but is phylogenetic relationship a sufficient criterion for predicting ecological function? Ecologists have assumed that the function of invertebrates in soil systems can be predicted at a low level of taxonomic resolution, but the authors' research indicates that critical functional parameters--e.g., feeding behavior, developmental rate, and reproductive mode--are rarely predictable above the generic level. Since morphology is more strongly conserved than behavior, feeding guilds or functional groups based on broad taxonomic relationship or untested assumptions about correlations between trophic morphology and feeding behavior have little meaning for nematophagous arthropods from grassland soils in Colorado.

AN - 15271976; 2037043 AB - Baermann funnels were modified to eliminate or reverse the small temperature gradient (1-2 C/cm) across the soil layer that normally results from water evaporation. Extraction of Meloidogyne incognita from sandy loam, Tylenchulus semipenetrans from sandy clay loam, and Rotylenchulus reniformis from silt was greatly accelerated simply by covering funnels to prevent evaporation. In most cases, covering increased the nematodes extracted by 10-100 times after 5.5-48 hours. Faster and more efficient extraction of R. reniformis occurred over a wide range of ambient temperature (18-29 C). Effects of ambient temperature and temperature gradient direction on Baermann funnel extraction of R. reniformis were partly inconsistent with the behavior of R. reniformis in agar.

The seed bank produced 84 taxa, including 5 tree species, 7 shrubs or woody vines, 14 grasses and 53 forbs identifiable at least to genus. The seed-bank treatment produced the greatest above ground biomass. Adding seed of reclamation species to the seed bank resulted in a community which had less total biomass, less total biomass in native species and fewer established native species with lower populations and biomass than native species community with out reclamation species.

AN - 15271265; 2037072 AB - This study examined the hypothesis that predation by forest birds restricts expansion of low-density populations of the spruce budworm Choristoneura fumiferana (Lepidoptera: Tortricidae). Only two species, Canada Warbler and Golden-crowned Kinglet, showed numerical responses to increasing budworm numbers. The percentage of the budworm population consumed by birds decreased as budworm numbers increased. Birds consumed 84% of the larvae and pupae where budworm populations were low, 22% where budworm populations were intermediate between low and high density. Once forth-instar larvae exceeded 10 super(6) individuals/hectare, bird predation was ineffectual. Birds are capable of dampening the seriousness of spruce budworm infestations when habitats are suitable for supporting adequate populations of these effective predators.

An aqueous extract of wheat acted as a non-competitive inhibitor (K sub(i) = 0.79 mu g/200 mu l) of MFM amylase. Inhibition occurred through the range pH 5.5 to 9.5. Mediterranean flour-moth amylase was not as sensitive as amylase from two granivorous coleopterans to two purified amylase inhibitors (ca 10 kDa) from wheat but was inhibited to a greater extent by partially purified wheat fractions that contained higher molecular weight albumins.

After the brine source was eliminated herbaceous plants, shrubs and forest tree seedlings became established and developed rapidly. Establishment began in the first year and by Year 4 the site had developed into a healthy young forest. Results show that Allegheny hardwood forest sites damaged by brine water will rapidly revegetate once the brine discharge is stopped if there is a seed supply and if the area is fenced to exclude deer.

AN - 15266826; 2026898 AB - Female eastern spruce budworm, Choristoneura fumiferana (Clemens), inoculated sublethally as fourth or fifth instars with Nosema fumiferanae (Thomson), exhibited significant reductions in size, fecundity, and total egg complement. Mating success and egg fertility were similar for treated and control insects. The presence of disease improved the positive correlation between fecundity or total egg complement and female pupal weight without significantly reducing the slope. Total egg complement was negatively correlated with disease load. JF - Environmental Entomology AU - Bauer, L S AU - Nordin, G L AD - North Cent. For. Exp. Stn., USDA, For.

AN - 15262884; 2026935 AB - A simple, complete mixing model is used to evaluate the degree of distortion involved in modeling chemical exchange and transport at the soil surface as a lumped rather than a distributed process. A complete mixing model was coupled to the kinematic cascade model, KINEROS, to provide a distributed representation of chemical exchange and transport. A lumped model was developed by ignoring spatial variations of chemical concentration in overland flow and in the mixing zone. The lumped model predicted significantly lower peak chemical concentrations and arrival times that were too short. Caution should be used when a lumped model is used to describe chemical exchange and transport on a cascade of planes.

Storm hydrographs were separated by using watershed-specific baseflow rise rates of 0.002-0.013 cfsm/hr. Median SF and QP were 0.0014 in and 0.43 cfsm, respectively, for all storms. Total storm rainfall (PPT) and initial flow (QI) were important stepwise regression variables in accounting for the variation in SF and peak flow above initial flow (QPI); 30- and 60-min rainfall intensities and rainfall duration were relatively unimportant.

Moon Lake, which receives channeled inflow from an intensively cultivated soybean, rice, and cotton watershed (166 km super(2)) and limited overland flow from surrounding lands, exhibited depositional patterns that were associated with (1) points of inflow, (2) flow patterns, and (3) lake morphology. From 1954 to 1965, 70 percent of the lake bottom experienced accumulation rates greater than 2 cm/yr. If current sediment accumulation rates continue, open water habitat in the lake will be reduced by only 3 to 7% during the next 50 years. JF - ENVIRON. GEOL. WATER SCI.

AN - 15251682; 2014762 AB - Soybean lipoxygenase-1 produces a preponderance of two chiral products from linoleic acid, (13S)-(9Z,11E)-13-hydroperoxy-9,11-octadecadienoic acid and (9S)-(10E,12Z)-9-hydroperoxy-10,12-octadecadienoic acid. The former of these hydroperoxides was generated at all pH values, but in the presence of Tween 20, the latter product did not form at pH values above 8.5. As the pH decreased below 8.5, the proportion of (9S)-hydroperoxide increased linearly until at pH 6 it constituted about 25% of the chiral products attributed to enzymic action. Below pH 6, lipoxygenase activity was barely measurable, and the hydroperoxide product arose mainly from autoxidation and possibly non-enzymic oxygenation of the pentadienyl radical formed by the enzyme. The change in percent enzymically formed 9-hydroperoxide between pH 6.0 and 8.5 paralleled the pH plot of a sodium linoleate/linoleic acid titration.

Results indicated that larvae parasitized before reaching the fifth instar by either Microplitis spp. may cause considerably less damage to the host plant than unparasitized larvae. The fifth instar apparently is suitable only for development of M. croceipes . JF - Journal of Economic Entomology AU - Powell, JE AD - USDA-ARS, Insect Rearing Res. Unit, P.O.

AN - 15246495; 2008427 AB - Recent analyses have shown that introduced parasitoids and predators have not differed significantly in their rates of establishment or success as agents of biological control. However, it is true that introductions of predators have been attempted much less often than introductions of parasitoids. This may be partly because of controversy over the attributes of the ideal natural enemy. A more basic obstacle has been the lack of a methodology for identifying any but the most pre-specific of predators of target pests. The authors proposes a new methodology, using on-the-spot serological stomach analysis of predators. The feasibility of this approach is illustrated with data from monoclonal antibody-based ELISA assays of predators fed larvae of species of the corn earworm complex.

AN - 15242839; 1998696 AB - A common practice for grazing land in the humid, eastern USA is continuous grazing with little or no fertilizer use. Concentrations and transport of nutrients from a 28-ha unimproved grassed watershed were assessed in east-central Ohio for 2 yr without the presence of livestock, for 3 yr with a 17-cow beef (Bos taurus ) herd grazing during the summer months only, and for an additional 6-yr period with all-year grazing with hay being brought in for winter feed. Nutrient concentrations remained low during all three grazing levels. An exception was K concentration, which increased with all-year grazing. All-year cattle grazing/feeding on an unimproved pasture in this area would not be expected to produce degradation of stream water quality from nutrient concentrations or transport.

AN - 15241406; 2001939 AB - Cloud water and rainwater were examined at remote sites in southeastern Alaska and coastal Oregon using standardized collection and analytical techniques. Cloud water and rainwater were characterized by extremely low concentrations of most ions except SO sub(4)u2 super(-), Na super(+), and Cl-. Acidity was greater than expected because of organic acids from unknown sources. Concentrations of NO sub(3)u- and NH sub(4)u+ were extremely low, especially compared to samples collected similarly in the eastern USA. Rainwater did not differ between Alaska and Oregon except in concentrations of Ca super(2+), Mg super(2+), K super(+), Na super(+), and Cl super(-). Cloud water generally had higher concentrations of ions than rainwater, especially in NO sub(3)u-, NH sub(4)u+, and SO sub(4)u2 super(-). Ion concentrations were highly variable and non-normally distributed. Sample sizes in future studies should be large (> 40). Cloud water deposition may be very important in terms of potential pollution effects and nutrient cycling in ecosystems with frequent cloud cover.

AN - 15221920; 1986693 AB - The balsam twig aphid, Mindarus abietinus Koch, infested nearly all trees in a range-wide provenance plantation of balsam fir, Abies balsamea (L.) Mill., in Michigan. Large populations of the aphid were correlated with low survival and reduced developmental rates of the spruce budworm, Choristoneura fumiferana (Clemens). The authors propose that chronic, high susceptibility of trees to aphids could reduce concomitant susceptibility to budworm through direct (competition) and indirect (host and community-level) effects.

Findings suggested that HSCAS can modulate the toxicity of AF in growing barrows (perhaps via sequestration and reduced bioavailability in vivo) and may offer a novel approach to the preventive management of aflatoxicosis in animals.

AN - 15219806; 1989349 AB - A chemical method for the purification of rat placental transferrin receptor is described. After initial solubilization and concentration by ammonium sulfate precipitation, radioiron-tagged diferric transferrin was added to the dialyzed receptor fraction and subjected to anion-exchange chromatography on DEAE-Sephacel. Elution with a Tris-HCl buffer gradient yields a single fraction of radioactivity containing both free transferrin and the receptor-transferrin as a complex. Further separation of the receptor-transferrin complex from the free transferrin is achieved by gel chromatography on a AcA34-Sepharose 6B separation system. Final purification is obtained by preparative gel electrophoresis in 5% polyacrylamide gels.

Body weight gains were significantly depressed by the AF and the AF + DON treatments for days 7, 14, 21, and 28. Body weights and body weight gains were only slightly reduced in the DON treatment. Changes in serum enzymatic activities of alkaline phosphatase, aspartate transaminase, creatine kinase, and gamma -glutamyl transferase were noticed in pigs given treatments with AF alone and those given AF + DON. Total iron binding capacity and serum total protein, albumin, cholesterol, BUN, and glucose concentrations were decreased, whereas prothrombin and activated thromboplastin times were increased by AF and AF + DON treatments.

Levels of fusaric acid comparable to those found near the fungus increased mortality of H. zea to gossypol, the saponin, and 6-methoxy-2-benzoxazolinone, and decreased the development rate of surviving larvae exposed to gossypol and 6-methoxy-2-benzoxazolinone. Some effect was also noted for levels of fusaric acid found generally distributed throughout infected plants.

AN - 15216525; 1983052 AB - The effect of temperature on developmental rates and demographic statistics of apterous and alate Russian wheat aphids (RWA), Diuraphis noxia (Mordvilko), was studied in the laboratory. An estimate of the lower threshold for development of immatures was determined (4.1 degree C). Degree-day (DD) requirements from birth to the onset of reproduction were determined for apterae (139 DD) and alatae (158 DD). Gross and net reproductive rates of both morphs were greatest at the low temperature regime and declined with increasing temperature. When expressed on a time scale of days, intrinsic rates of increase of both morphs were highest and mean generation time shortest at the high temperature regime.

AN - 15216337; 1983534 AB - Domatia are small invaginations and hair tufts usually found at vein junctions on the undersides of leaves in many woody dicots. Domatia of 32 plant species (of worldwide origin from 18 families) growing in California, Hawaii, and Costa Rica were examined for mites. Domatia of 31 of 32 (97%) of these plants contained mites, and 24 of 32 (75%) contained mite eggs. Mites were found within the domatia of 48% of the sampled leaves. The domatia of 26 of 31 (84%) plants had mite species considered beneficial (primarily in the families Phytoseiidae and Tydeidae, but also Bdellidae, Cheyletidae and Stigmaeidae), while 6 of 31 (19%) had mite species considered harmful (Tenuipalpidae and Eriophyidae).

About 50% of all larvae fed on the ears. A density assessment method which uses the number of A. americanum on less than or equal to 5 body areas to predict the total number of ticks (tick burden) on the left side of a calf is presented. Mean tick burden in a herd of calves can be estimated by an examination of from 14 to 100% of all calves depending on the level of precision required for the estimate.

AN - 15215391; 1977555 AB - Feeding preferences of individual American cockroaches (Periplaneta americana (L.)), smokybrown cockroaches (P. fuliginosa (Serville)), brownbanded cockroaches (Supella longipalpa (F.)), and Eurycotis floridana (Walker) were examined in the laboratory to test the hypothesis that dry distiller's grain is as attractive as dry cat chow, laboratory rat chow, or distiller's grain with uric acid. Except for E. floridana , females typically spent more time on baits than did males. Only the brownbanded cockroach showed a significant preference for cat chow. Data were variable for the other three species, but showed that adults readily accept dry distiller's grain. The authors conclude that this bait is preferable to the others for field studies of cockroach population dynamics.

AN - 15212754; 1983257 AB - A field study with controlled infestations of eggs of the western corn rootworm, Diabrotica virgifera virgifera LeConte, was conducted over a four-year period. The percentage of insects surviving to adulthood was significantly reduced at an infestation of 2,400 eggs per 0.3 m of row compared with rates of 300, 600, and 1,200 eggs per 0.3 m of row. Survival to adulthood varied among years suggesting that biotic or abiotic factors in the soil, possibly soil moisture, may have influenced survival. The Julian date associated with mean adult emergence was significantly later at the 2400 egg infestation rate than at lower rates.

AN - 15212373; 1986785 AB - Analyses were performed on a simulation model describing the population dynamics of adult Diabrotica barberi Smith and Lawrence in field corn. Overall goals were to gain a better understanding of the dynamics of this insect/plant system and explore possibilities for improved population management. Factorial analyses suggested that the timing of emergence and dispersal, relative to flowering, are the major factors contributing to the presence of beetles during the flowering period, but their relative contributions depend on the seasonal time of flowering. Simulation was used to examine the relationship between adult abundance, oviposition, and crop phenology and to formalize hypothetical improvements in current action thresholds for making recommendations for corn rootworm control based on adult sampling.

Developmental rates of cohorts exposed to variable temperatures were similar to expected developmental rates determined from constant temperature studies. Age-specific life table statistics differed among alate and apterous R. padi exposed to identical temperatures regimes.

AN - 15210063; 1983341 AB - Evidence of 58 predation events by Phidippus audax (Hentz) was obtained from a 0.1 ha old field site that included cotton in the Delta of Mississippi. Three crop pest species accounted for 60% of the prey records: tarnished plant bug (TPB) (22%), spotted cucumber beetle (SCB) (22%), and three-cornered alfalfa hopper (TAH) (16%). Censuses (35) of cotton at this site indicated that the most abundant potential prey, SCB, had one of the lowest capture rates by P. audax , 1.9%. Other spiders as a group were captured at a rate of 11.4%, TAH at a rate of 10.2%, and TPB at a rate of 4.3%.

AN - 15207445; 1977986 AB - The relationship of serum complement activity and bacteriostatic activity was investigated in male guinea pigs given aflatoxin and/or rubratoxin. In experiment 1, guinea pigs were give 0.6 mg of aflatoxin/kg of body weight, PO, once. In experiment 2, guinea pigs were given 0.02 mg of aflatoxin/kg, PO, and/or 8 mg rubratoxin, PO, 11 times. Aflatoxin (0.02 mg/kg) had no effect given alone, but potentiated the effect of rubratoxin. In both experiments, changes in complement activity were accompanied by similar but not always significant changes in bacteriostatic activity of serum. Guinea pigs given 0.06 mg of aflatoxin/kg had significant changes in complement titers and in serum alkaline phosphatase, alanine aminotransferase, and aspartate aminotransferase activities. Guinea pigs given repeated oral doses of aflatoxin and/or rubratoxin had changes in complement titers, bacteriostasis, and alkaline phosphatase and aspartate aminotransferase activities, but not in alanine aminotransferase activities.

AN - 15205387; 1980549 AB - Normal and irradiated laboratory-reared Heliothis zea (Boddie) moths were released in screened field cages and in fields of tobacco and cotton. Laboratory-reared moths irradiated with 10 krad and released in field cages were competitive with nonirradiated laboratory-reared moths. The competitiveness of irradiated moths was not altered by the time interval (5 and 30 h) between irradiation and release, the mating status of the male, or by the time interval (24 and 48 h) between mating and release. Normal and irradiated, laboratory-reared males released in the field in either the presence or absence of laboratory-reared females were not significantly different in their nocturnal behavior and mating competitiveness. The interaction of wild and laboratory-reared moths was largely limited to wild males mating with laboratory-reared females.

Royle, in the Punjab region of Pakistan and Karnataka State in southern India. Host range studies were conducted in a quarantine laboratory in Florida with a fly colony from India. Females tested on 29 plant species in choice tests oviposited on all, but preferred hydrilla. Fifty-one plant species were included in larval no-choice tests, resulting in small numbers of adults being produced on six species. Curly leaf pondweed, Potamogeton crispus L., an associate of hydrilla in Asia and an introduced weed in the United States, produced the most adults. The studies indicated that H. pakistanae was safe to release in the United States for biological control of hydrilla.

AN - 15187856; 1971740 AB - The biological control potential of Edovum puttleri Grissell, an exotic egg parasite of Leptinotarsa decemlineata (Say), was examined in experimental potato plots. The parasite does not overwinter in Maryland, but through annual inoculative releases it consistently parasitized Colorado potato beetle (CPB) egg masses throughout the season. Edovum puttleri reproduced and maintained itself in potato plots for 15 weeks. The random sampling of CPB egg masses to evaluate the parasite in the field is described.

A generalized density-integral model is developed on the basis of some calculus of mass theory. To demonstrate the application and efficacy of this new integral approach, specific equations are developed for slash pine in the West Gulf Coast of the United States. These integrated equations, when compared with weight-ratio equations, gave more precise estimates of sectional bole weight.

AN - 15182949; 1965440 AB - Wheat plots were established in central and eastern North Carolina in the falls of 1985 and 1986 to determine yield reduction caused by Erysiphe graminis f. sp. tritici on winter wheat cultivars Saluda and Coker 983. Check plots were compared with plots kept nearly disease-free with three to four foliar applications of triadimefon. The efficacy of triadimenol for mildew control when applied as a seed treatment, with or without different triadimefon foliar spray schedules, also was determined. Significant disease control resulted from foliar applications of triadimefon on both cultivars; however, the only consistent yield reductions were observed with Saluda. Triadimenol seed treatments lowered mildew severity and increased grain yields. Area under the powdery mildew curve was negatively correlated with yield.

AN - 15173073; 1949895 AB - The energy crisis of the 1970s stimulated renewed research on the use of forage legumes as inexpensive sources of N in cropping systems. New research programs were begun to improve the N assimilation of forage legumes, and to convert scientific knowledge about legume N sub(2) fixation into technological choices that would support a profitable and sustainable agriculture. The authors assess the status of selected technologies that have resulted from this research. Four technologies, viz. alfalfa germplasm with enhanced activities of nodule enzymes, alfalfa germplasm unable to fix N sub(2), alfalfa germplasm with improved N accumulation in herbage or roots, and improved rhizobial strains for inoculum have reached the developmental stage of field testing.

AN - 15171956; 1949916 AB - Bacteria, fungi, and algae differ in their responses to pesticides; responses are often related to the biochemical mechanisms of action of the pesticide and pesticide concentrations in the soil. Total microbial populations in soils are often unaffected or only slightly affected by pesticide applications, but populations and activities of individual species or groups (e.g. cellulose decomposers) of microorganisms may be greatly affected. Pesticide concentrations greater than those resulting from field applications can cause interruption of microbial activities and shifts in populations. Most pesticides used at field rates do not appear to cause significant lasting effects on the microbial activities most related to soil fertility.

AN - 15170820; 1951830 AB - The alfalfa seed chalcid, Bruchophagus roddi (Gussakovsky), is a host-specific insect that lays eggs in the developing seeds of alfalfa. In laboratory bioassay, females made in-flight evaluations of olfactory stimuli that emanated from an array of host and nonhost flowers. The outcome of choice tests depended on pretest conditions that varied in sequence and time of exposure to host and nonhost plants. Specific flight and landing behavior was elicited or inhibited by conditions that prevailed before the choice test.

AN - 15169092; 1948218 AB - The DNA from 31 isolates and a reference strain of Mycobacterium paratuberculosis was digested individually with restriction endonucleases BstE II and Pst I. DNA fragments were separated by gel electrophoresis and analyzed. The isolates were from 23 American states, Argentina and Nova Scotia. The results confirm other reports and indicate that organisms identified as typical M. paratuberculosis isolates are genetically very similar. It may be possible to use restriction endonuclease analysis to differentiate isolates of M. paratuberculosis from other slowly growing mycobacteria. The genetic similarity also indicates that it may be possible to develop a diagnostic probe that is specific for M. paratuberculosis .

AN - 15162443; 1941996 AB - Triticale PI 429155 was selected as a possible source of leaf-rust resistance for wheat. This cultivar expresses an infection type (IT) 1 super(+) and a latent period (T sub(50)) of 14 days when inoculated with culture 7434-1-1T of Puccinia recondita . The effects of the incomplete hypersensitivity and slow-rusting resistance of PI 429155 were evaluated by separating the genetic factors for resistant IT and long T sub(50) into different experimental cultivars, measuring the components of resistance on adult plants, and evaluating the resistances in epidemics. The derived cultivars possessed either no resistance factors (susceptible, SUSC), the factors for long T sub(50) and susceptible IT (slow rusting. SR), the factors for resistant IT and moderately short T sub(50) (hypersensitive resistance, HR), or factors for both forms of resistance combined (slow-rusting and hypersensitive resistances, SR + HR). SR, HR, and SR + HR all reduced the infection frequency on flag leaves. JF - Phytopathology AU - Wilson, J AU - Shaner, G AD - USDA-ARS, Coastal Plain Exp.

AN - 15134500; 1926752 AB - The leaf beetle Trirhabda bacharidis (Weber) is the dominant herbivore of the woody shrub Baccharis neglecta (Britt.) in central Texas. Eggs were deposited in clusters on the base of the main stem of the plant from April to June and remained dormant for 7-10 mo. In 1984 and 1985, mean populations of 91 and 572 neonate larvae per plant, respectively, were found in late winter from eggs deposited on the base of main stems. Larvae often defoliated the plant. Mature larvae dropped or crawled to the ground in March and April and pupated in the soil. Mean adult populations of 154 and 239 beetles per plant emerged in April 1984 and 1985, respectively; they also defoliated some plants.

Theoretically the crystalline protein matrix that occludes and surrounds each virion containing DNA should provide some protection against inactivation by sunlight-UV. No significant differences, however, were obtained in either the extent or rate of inactivation when nonoccluded, polyhedra derived virions (PDV) and tissue culture derived virions (TCNOV), or virions occluded in polyhedral inclusion bodies (PIBOV) of the singly-enveloped nuclear polyhedrosis virus of Heliothis species (HzSNPV) were exposed to a simulated sunlight-UV source (SUV). There was smearing of the EcoRI restriction enzyme (REN) patterns and an increase in lower molecular-weight species after exposure to SUV of both naked viral DNA and DNA of virions occluded in polyhedral inclusion bodies (PIB).

The alkalinities of clear lakes decreased with respect to calcium and magnesium concentrations. Lake sulphate levels increased with increasing sulphate deposition. At present deposition levels, about 5-10 per cent of the clear lakes were acidified. Coloured lakes were less affected by acid deposition. The decrease in coloured lake alkalinity compared to calcium and magnesium concentrations with increasing sulphate deposition levels was only about 60 per cent of that in coloured lakes. Lake sulphate decreased with increasing colour at all deposition levels. JF - Environmental Monitoring and Assessment AU - Nichols, D S AD - USDA Forest Service, Grand Rapids, Minn.

An upper reactor represented surface runoff water, and a lower represented the Effective Depth Transfer (EDT) which was defined as a surface homogeneous soil layer with constant dissolved concentration. Solute concentrations in the EDT were assumed to equal the solution concentration at the soil surface as determined by an analytical solution of the one-dimensional diffusion equation subject to mass transfer through a laminar boundary layer at the soil surface/runoff interface. The time-dependent EDT varied as a linear function of the square root of time, and calculated soil surface concentrations were comparable to the exact analytical solution of the solute diffusion equation. The EDT model should predict chemical data more accurately than previous empirical models, and the ability to change the physically-based parameters enabled application to different locations with different runoff regimes, soil properties and solute characteristics.

The chemical composition of leachates from the upper parts of the soil columns differed between the different rainfall treatments, but this difference disappeared at the bottom of the columns. The leachates from the bottom of the columns became more acidic with time. Other aspects of this problem were being studied.

These remotely measurable optical properties had potential applications in the estimation of lake water quality on the basis of remote sensing data. However, no relationship was found between reflectance and acidification status. Regression models were developed to predict total pigments and dissolved organic carbon using reflectance data. These parameters could be estimated remotely, though remote estimation of pH, alkalinity and aluminium was not possible on the basis of reflectance. There are 73 references.

The amendments comprised 4 rates of compost application (0-135 Mg per ha in greenhouse and growth chamber; 0-240 Mg per ha in field plots) and a lime treatment with 4 combinations of nitrogen and phosphorus (at rates of 0 and 200 kg per ha). Determination of total nitrogen in fescue clippings, roots and crowns showed a linear growth response to compost amendment in all 3 environments, with residual compost in the second year producing 50 and 60 per cent of the first year yields in growth chamber and field, respectively. Fescue nitrogen utilization in the greenhouse and growth chamber experiments, estimated from total nitrogen concentrations in the entire plant, was 8 per cent for the first year and 5 per cent for the second, compared to 7 per cent in field plots for first-year clippings alone. Yields equivalent to those obtained with complete fertilizer were realised by the 135 Mg per ha compost amendment in the greenhouse, and by 60 Mg per ha in field plots. Compost treatment of soil for fescue production appeared feasible but predictions of growth and nitrogen utilization based on greenhouse and growth chamber studies should be validated with field trials.

Fractile diagrams and variances showed that the generalized Kozeny-Carman equation with exponent value of 4 or 5 yielded good estimates of the frequency distribution of hydraulic conductivity scaling factors from effective porosity measurements, although 4 was the more widely applicable exponent. Results for combined data from 8 soils indicated that the proposed method could be applied across different layered soil types. Direct estimates of hydraulic conductivities across an area obtained with the empirical equation for combined soils produced a fair first order approximation to experimental data, and could be applied in resource management models where measured data were not available.

Planning and common property equilibria were derived. The model was applied to an area in the Texas High Plains. Simulation indicated that transition away from the irrigation of sorghum was twice as fast when optimized. Economic benefits to groundwater management ranged from 0.36 to 4.16 million U.S. dollars as the interest rate varied from 5 to 2 per cent.

Thus, measured lake chemistry in the Adirondack Park region of N.Y., was compared with field reflectance measurements, remote reflectance measurements (aircraft and satellite) and laboratory and airborne laser fluorosensor data. Of the methods investigated, laser fluorosensing was feasible for the remote prediction of lake dissolved organic carbon (DOC), hydrogen ion and aluminium concentration while reflectance measurements were feasible for estimating lake chlorophyll, DOC and transparency. Remote sensing methods might provide an alternative, less precise, method of monitoring lake chemistry in the very large numbers of wilderness lakes.

Stream gauge analysis for areas such as the Atlantic coastal plain suggested that another dimensionless unit hydrograph with a significantly different shape would be required for coastal flatlands. An average dimensionless unit hydrograph was developed for such areas using the U.S. Army Corps of Engineers' Flood Hydrograph Package (HEC-1). Peak-flow frequency curves were then generated for stream gauge sites in the Delmarva peninsula. The resulting peak discharges approximated observed values reasonably closely.

Drought effects on the final leaf area of individual leaves were hypothesized to depend on the leaf developmental stage at which drought occurred. To evaluate this hypothesis, final leaf area and cell number were measured for soybean (Glycine max (L.) Merr.) leaves that were at different stages of development when single or cyclical drought treatment was imposed. Leaf emergence rate from the meristem, as depicted by changes in the plastochron index, was not as sensitive as leaf expansion to cyclical droughts. For leaf expansion, small leaves, once they emerged from the meristem, suffered larger decreases in growth than leaves undergoing rapid leaf area expansion. Decreases in final leaf area as a result of a cyclical drought were correlated with decreases in final cell number. Decreases resulting from a single 8-d drought were dependent on the age of the leaf at the time of drought, because small leaves were found to have proportionately larger decreases in final cell number and area than larger leaves. These results indicated that age-dependent leaf responses to drought are based on the relative activity of cell division and expansion at the time stress was imposed.

AN - 78724243; 3239851 AB - The effect of Fusarium-produced T-2 toxin on tumor growth was evaluated in ICR, CFW, and C57B6/6 mice inoculated with murine sarcoma, Ehrlich ascites carcinoma, or B16F1 melanoma tumor cell lines. Mice were given T-2 toxin intragastrically either at the rate of 2 mg of toxin/kg of body weight daily for 5 days or a single dosage of 4 mg of toxin/kg and were inoculated SC with tumor cells 1 or 2 days after administration of toxin. Tumor growth was assessed 15 to 41 days after tumor challenge by determining the frequency of tumor development and tumor weights. Significant increases in the frequency of development of murine sarcoma (P less than 0.005), Ehrlich ascites carcinoma (P less than 0.01), and B16F1 melanoma tumors (P less than 0.05) were detected in toxin-treated mice, compared with control mice. Murine sarcoma and B16F1 melanoma tumor weights also were significantly (P less than 0.01) higher in toxin-treated mice. The effect of T-2 toxin on tumor growth was more marked after 5 daily treatments than after a single dose.

AN - 78709455; 3071196 AB - The influence of immunosuppression by T-2 mycotoxin on the fungal disease aspergillosis was investigated in rabbits. Four groups of rabbits (groups 1A, 1B, 3A, and 3B) were given 0.5 mg of T-2 toxin/kg of body weight/day, PO; in addition, rabbits of groups 3A and 3B were exposed to aerosols of Aspergillus fumigatus conidia from days 7 through 16. Rabbits of groups 2A and 2B were exposed to A fumigatus aerosols, but were not given T-2 toxin, and rabbits of group 0 served as controls. Two rabbits of group 1A, 1 rabbit of group 1B, and 1 rabbit of group 3A died before scheduled necropsy. Rabbits of groups 1A, 2A, and 3A were killed and necropsied on day 17, and the remaining rabbits (groups 0, 1B, 2B, and 3B) were killed and necropsied on day 28. Changes caused by T-2 toxin included leukopenia, marginal anemia, and increased number of and morphologic changes in nucleated erythrocytes by day 21, followed by a regenerative hematologic response. Serum alkaline phosphatase and sorbitol dehydrogenase activities and antibody response to A fumigatus (as measured by an indirect hemagglutination test) were decreased by T-2 toxin ingestion. Rabbits with aspergillosis had leukocytosis, increased PCV, and increased antibody response to A fumigatus. Histologic lesions consisting of centrilobular hepatocellular swelling, portal and periportal fibrosis, and lymphocyte necrosis and/or depletion within secondary lymphoid tissue were observed in most rabbits treated with T-2 toxin. Normal defense mechanisms against A fumigatus infection were compromised by T-2 treatment, as evidenced by the severity and extent of lung lesions, greater number of hyphal elements observed, and greater number of colonies of A fumigatus isolated from rabbits of groups 3A and 3B. There were no significant changes in group-0 rabbits.

AN - 78685074; 3230074 AB - Cattle's grazing of the locoweed Wahweap milkvetch (Astragalus lentiginosus var. wahweapensis) was evaluated on desert and foothill winter range during the winter of 1986 to 1987. Dry, dead stalks of Wahweap milkvetch that had grown in 1985 and 1986 made up 15% of cattle diets overall, and 24% of diets when cattle grazed gravelly benches where it was abundant. Nutritional quality of Wahweap milkvetch was higher than of most associated forage, but its alkaloid concentration varied among the senescent stages. One cow aborted and two cows developed clinical signs of locoweed poisoning, including water belly (hydrops amnii). Microscopic lesions consisting of cytoplasmic foamy vacuolation were evident in both the dam and fetus. Because senescent stalks of Wahweap milkvetch are palatable and readily grazed by cattle, ranchers should not permit cattle to graze infested sites until other green forage is available in the spring.

AN - 78591483; 3062145 AB - Nutrient requirements for proliferation and differentiated function of individual cell types can be determined using cell culture methodologies. Human epidermal keratinocytes are stimulated to grow by choline supplementation in the presence of myo-inositol when grown in a commercial nutrient medium containing six other defined supplements. The optimal range of choline concentrations varied among donor cell lines, but consistently fell between 36 microM and 180 microM. Addition of 72 microM choline increased cell yield to 250 +/- 38% of that produced by myo-inositol supplementation alone and 92 +/- 8% of that produced by addition of a highly mitogenic hypothalamic extract, which was previously required for good growth in this culture system. Supplementation of the basal medium with both the extract and choline resulted in 165 +/- 13% of the cell yield observed with the extract addition alone. Supplementation with other phospholipid precursors did not further increase keratinocyte growth. Neither dermal fibroblasts nor epidermal melanocytes were stimulated by supplementation with choline, suggesting the high keratinocyte requirement is unusual. This completely defined culture medium for keratinocyte growth should prove useful in analyzing the role of phospholipids and other nutrients in human epidermis.

AN - 78743251; 3247926 AB - The effect of T-2 toxin on host resistance to acute and latent Babesia microti infections was evaluated in mice and was compared with the effects of the immunosuppressive drugs dexamethasone and cyclophosphamide. Mice with acute or latent B microti infection were treated with 2 mg of T-2 toxin/kg of body weight, 0.2 mg of dexamethasone/kg, or 30 mg of cyclophosphamide/kg daily for 5 days. Treatment with dexamethasone or cyclophosphamide caused significant (P less than 0.05) increases in Babesia parasitemia during acute infection and significantly (P less than 0.05) prolonged the duration of parasitemia during acute babesiosis. Treatment with T-2 toxin caused a transient significant (P less than 0.05) increase in Babesia parasitemia on day 10 after acute infection and numerical, though statistically nonsignificant, increases in the maximal level and duration of parasitemia during acute babesiosis. Significant (P less than 0.005) recrudescence of parasitemia was observed in the dexamethasone- and cyclophosphamide-treated mice with latent Babesia infection. Treatment with T-2 toxin did not cause recrudescence of parasitemia in mice with latent Babesia infection.

AN - 78554001; 3143346 AB - Interactions between vascular endothelium and low density lipoprotein (LDL) have been implicated in the development of atherosclerosis. The effect of normal and oxidized LDL (Ox-LDL) on prostaglandin release by cultured adult human saphenous vein endothelial cells was investigated. Ox-LDL induced a rapid release of prostacyclin (PGI2) to levels which were several-fold higher than those observed with control LDL. PGI2 release was concentration-dependent and was biphasic, with a first peak occurring within 30 minutes (followed by a decrease), and a second peak occurring after several hours of incubation. PGI2 production was inhibited by lipoprotein-depleted serum and by indomethacin, an antagonist of cyclooxygenase activity. These cells produced mainly PGF2 alpha, with some PGE2 and PGI2 when stimulated by the ionophore A23187 at confluency. However, among these prostanoids, mainly PGI2 was produced in response to Ox-LDL. The data indicate that Ox-LDL induces the production of PGI2 by human vascular endothelial cells.

A program was needed to reduce saline pollution in the Colorado River. The program implemented provided 75 % federal cost-share money for installation of on-farm improvements. The new irrigation systems saved farmers water, fertilizer, and labor and increased yields made irrigating easier. Through water management tactics such as upgrading level basin systems, installing accurate measuring devices and adopting good water conservation systems, the farmers reduced diversions to the valley by 20 % and irrigation return flow by half. In addition, the Bureau of Reclamation is currently building the world 's largest reverse osmosis desalting plant to treat smaller volumes of drainage flow now going into the Gulf of California.

In glacial tills causes for joints include stresses from overriding ice, stress release, desiccation and rebound. They may also be propagated from fracture traces in the underlying rock. In loess, alluvium, and lacustrine materials, many of the joints appear to be propagated upward indicating a tectonic relationship. Joints in some lacustrine and alluvial deposits have been attributed to desiccation and stress release. Further investigations will probably show that many soil joints are tectonically related and that joints in many terrestrially deposited sedimentary rocks predate induration. Soil joints are common in nonindurated materials. In most cases soil joints can be measured and defined and should be used in developing new models for water movement in the unsaturated zone. These models could improve our understanding of the movement of nutrients, pesticides, and agricultural waste through the unsaturated zone into the groundwater.

AN - 78543456; 3194334 AB - The individual and combined effects of aflatoxin and T-2 toxin were studied in male broiler chicks (Hubbard X Hubbard). The experimental design was a 2 X 2 factorial design with dietary treatments of 0 and 2.5 micrograms/g aflatoxin and 0 and 4.0 micrograms/g T-2 toxin. The broilers were obtained at 1 day of age and housed in electrically heated batteries with feed and water available ad libitum until they reached 3 wk of age. Aflatoxicosis in this study was characterized by a significant (P less than .05) reduction in body weight, changes in red blood cell counts and serum levels of protein, albumin, glucose, cholesterol, and calcium, and magnesium, activity of the serum enzymes lactic dehydrogenase and alkaline phosphatase, and a significant (P less than .05) increase in relative weights of the liver, kidney, spleen, pancreas, proventriculus, and heart. Dietary T-2 toxin alone caused oral lesions, a significant (P less than .05) decrease in serum protein, albumin, potassium, and magnesium levels, and a significant (P less than .05) decrease in the activity of the serum enzymes lactic dehydrogenase and alkaline phosphatase. In the combination treatment of aflatoxin and T-2 toxin, significant (P less than .05) interactive effects were seen through a decrease in body weights, increase in the relative weights of the kidney, gizzard, and heart, and decrease in mean corpuscular volume and serum levels of potassium. These data indicate that aflatoxin and T-2 toxin can interact to produce synergistic toxicity. This synergism is a threat to poultry production due to the prevalence of these mycotoxins and severity of the interactive toxicity of these mycotoxins.

AN - 78521993; 3056139 AB - Rabbits were given T-2 mycotoxin orally at 0, 0.25, 0.5, and 0.75 mg/kg of body weight/day for 21 days. Only rabbits in the 0.75 mg/kg/day group (4 of 5 rabbits) died. Alveolar macrophages were harvested on day 22 and used for in vitro phagocytosis of killed Aspergillus fumigatus conidia. Cultures included sera from untreated rabbits or rabbits treated with T-2. Phagocytosis was significantly (P less than 0.01) reduced in cultures that used serum from rabbits treated with 0.5 mg of T-2/kg/day and alveolar macrophages from untreated rabbits or rabbits treated with T-2. There was little reduction in phagocytosis when alveolar macrophages from rabbits treated with T-2 and normal serum were used. Ingestion of 0.5 mg of T-2 toxin/kg/day significantly (P less than 0.05) reduced weight gain, serum alkaline phosphatase activity, serum sorbitol dehydrogenase activity, and serum bacteriostasis. Similar changes were found in the 0.75 mg/kg/day group, as well as a significant (P less than 0.05) reduction in PCV, total WBC, and differential leukocyte counts. Neutrophil counts decreased, but not significantly (0.05 less than P less than 0.10). Significant changes were not detected in alanine transaminase activity, aspartate transaminase activity, blood urea nitrogen concentration, or complement hemolytic activity. Histopathologic changes consisting of centrilobular hepatocellular swelling, mild portal and periportal fibrosis and lymphocyte necrosis within secondary lymphoid tissues developed in most rabbits treated with T-2. Thymic atrophy, bile duct reduplication, and lymphocyte depletion of secondary lymphoid tissues developed in the group given 0.75 mg/kg/day.(ABSTRACT TRUNCATED AT 250 WORDS) JF - American journal of veterinary research AU - Niyo, K A AU - Richard, J L AU - Niyo, Y AU - Tiffany, L H AD - USDA, Agricultural Research Service, National Animal Disease Center, Ames, IA 50010.

The erosion control and animal waste management practices in the National Handbook of Conservation Practices published by the Soil Conservation Service were readily accepted for BMPs. Similar practices were developed for forestry. Integrated Pest Management served as a BMP to reduce pesticide usage. Two major flaws of the process were: (1) the actual surface water quality problems and anticipated effects were often not defined, and (2) groundwater was not considered. BMPs in groundwater sensitive areas should be tailored to the local soil, climate and geological conditions. Recommendations for BMP development include: monthly meeting of all county USDA agencies; meeting of agencies at the state level; and targeting funds and staff time to solve recognized problems. It is concluded that, while some progress has been made in reducing NPS pollution of surface waters, considerable work on BMPs for the reduction of NPS loads to groundwater is required. BMPs for groundwater protection will rely heavily on management practices rather than structural practices.

AN - 78666422; 3066242 AB - The in vitro biologic effects of T-2 mycotoxin on the immune response of mice was undertaken. Twenty nanograms of toxin abrogated the immune response to the T-dependent antigen sheep RBC, whereas a partial response was observed when 2 ng was used. Analysis of cell culture viabilities indicated that cell death occurred with toxin doses that coincided with the diminished immune responses. A similar decreased response was observed against the T-independent antigen, TNP-lipopolysaccharide, indicating toxic effects on both B and T lymphocyte populations. Delay of toxin administration as much as 116 hours of the 120-hour incubation period still resulted in a substantially diminished immune response, indicating the toxin acts on both the afferent and efferent immune systems. Equal effects were observed for mice of the b, d, and k haplotype, indicating no apparent strain variability in sensitivity to T-2 mycotoxin effects. These results indicated that T-2 mycotoxin can modulate the immune response, and that this modulation is attributable to direct toxic effects on the cells of the immune system.

The comprehensible diseases are divided into those due to four classes of etiologic agents: toxicity, heredity, infection and deficiency. Cooperations between two members of these classes are described to illustrate the concepts of hereditary intoxication, infectious intoxication, toxic deficiency, hereditary infection, hereditary deficiency and infectious deficiency. Examples in which cooperations among members of three or four classes of etiologic agents are required to produce illness also are provided. It is concluded that there are only four known ways of becoming ill and that cooperations can explain much variability of human disease.

AN - 78413906; 3415240 AB - Calcium-induced changes in protein solubility play a role in a variety of important biological processes including the deposition of bone and dentin and the secretion of milk. The phenomena of salt-induced (calcium) precipitation of proteins (salting-out), and the resolubilization of these proteins at higher salt concentrations (salting-in) have been studied and quantitated using an approach based on the concepts of Wyman's thermodynamic linkage. Salting-out has been described by a salt-binding constant, k1, the number of moles of salt bound per mole of protein, n, and S1, the fraction soluble at saturation of n; salting-in has been described by corresponding constants k2, m, and S2. Analysis of salt-induced solubility profiles was performed using nonlinear regression analysis. Results of calcium-induced solubility profiles of two genetic variants of alpha s1-casein (alpha s1-A), (alpha s1-B), and beta-casein C (beta-C) at 37 degrees C, where hydrophobic interactions are maximized, showed no salting-in behavior and for salting-out, yielded k1 values of 157, 186, and 156 liters.mol-1 and n values of 8, 8, and 4, respectively. The values of k1 can be correlated with the apparent association constant for calcium binding to casein, while the values of n can be correlated with the number of calcium binding sites of the respective caseins. At 1 degree C, where hydrophobic interactions are minimized, nominally only hydrophilic and electrostatic interactions can be linked to the salt-induced solubility profiles; here beta-C is totally soluble at all calcium concentrations and alpha s1-B and alpha s1-A were now found to have salting-in parameters, k2 and m, of 2.5 liters.mol-1 and 4, and 11 liters.mol-1 and 8, respectively. alpha s1-A is more readily salted-in and studies on the variation of S1 with added KCl for this protein at 1 degree C indicated that salting-in is also mainly electrostatic in nature and may result from competition between K+ and Ca2+ for binding sites rather than from solute-solvent interactions as previously proposed. Comparison of k1 and k2 values between the two genetic variants, coupled with the known sequence differences (the A variant is a linear deletion of 13 amino acids) suggest the existence of a hydrophobically stabilized ion pair in alpha s1-B which is deleted in alpha s1-A; it is speculated that such bonds may play a role in other calcium-induced changes in protein solubility.

AN - 78503374; 3185108 AB - Cholesterol 5 alpha,6 alpha-epoxide (alpha-epoxide) and cholesterol 5 beta,6 beta-epoxide (beta-epoxide) were individually suspended in simulated gastric juice (pH 1.2) at 37 C, and their reaction was followed by gradient high performance liquid chromatography (HPLC) with flame ionization (FID) detection. Both epoxides reacted rapidly in the aqueous acid medium. The alpha-epoxide formed 6 beta-chlorocholestane-3 beta,5 alpha-diol (alpha-chlorohydrin) and 5 alpha-cholestane-3 beta,5,6 beta-triol (triol), while the beta-epoxide formed 5 alpha-chlorocholestane-3 beta,6 beta-diol (beta-chlorohydrin) and triol. The isomeric chlorohydrins reacted further to form the triol. In mildly alkaline aqueous medium, each chlorohydrin reverted to the epoxide from which it was formed. The data suggest that both epoxides, which have been reported to have adverse health effects in animals, would be largely hydrolyzed in the stomach and to the triol, which also has been reported to have biological activity. The data further suggest that residual chlorohydrins surviving stomach residence can be expected to revert to epoxide in the more alkaline intestinal environment.

Potassium bromide was uniformly applied to an 8 by 12-m plot and then ponded with a 100-mm irrigation. Twenty sites were sampled on a 1.8 by 2.5-m grid 6 days after irrigation. A 103-mm-diameter sample tube was inserted into the soil at 15-cm intervals. A 22-mm concentric subsample was obtained from the larger sample. The variances of the Br(-) concentration, water content, and total Br(-) recovery were not significantly different between the two sample sizes at the 0.05 significance level. The mean difference between the large and small samples was significantly different at the 0.1 level for Br(-) concentration and Br(-) recovery. The slope of the regression line was significantly different from 1 for Br(-) concentration only. Geostatistical structure analysis indicated that the variance of solute velocity using the large sample would only be about 3% smaller than that of the small sample. Although there was a significant bias toward the larger sample size for Br(-) concentration and recovery, spatial variability effects are far greater than sample size effects, and the Br(-) transport was adequately represented by the data collected using the small sample. The representative elementary volume was equaled or exceeded with the 22-mm diameter sample.

This change in yield reflects an integrated response of the parameters involved such as increased water-application efficiency, increased infiltration and storage from snow or rainfall, reduced evaporation from the soil surface , and the ability of plants to use the stored moisture more efficiently. A standard method is proposed for evaluating the benefits of windbreaks based on converting the change in crop yield to an equivalent change in water use. The equivalent water can be used to estimate changes in yields for other crops in the rotation system. The method is also applicable for evaluating the benefit of other conservation practices where yield differences are known. A distance of 10 windbreak heights (10h) is proposed as a standard for evaluating the effects of windbreaks on crop yield.

AN - 85269036; pmid-3412851 AB - An acoustic plethysmograph designed to measure body volumes of infants is described. This method uses the principle of the Helmholtz resonator in which the resonant frequency of a chamber is inversely proportional to the square root of the volume of air inside the chamber. After an object is placed inside the chamber, the change in resonant frequency is used to measure the volume of the object. The coefficient of variation of repeated measures of body volumes of 13 miniature piglets (5 to 18 days old, body weights 1253 to 2631 g) ranged from 0.3 to 3.2%. Body volumes measured by the acoustic method agree closely with those calculated from carcass analysis in which body volume is the sum of the volumes of total body water, fat, protein, and minerals. Fat-free mass computed from densitometry using a four-compartment model and body volume measurements from the acoustic method agrees with fat-free mass obtained from carcass analysis. The mean difference between methods was not significant: 1 ml for body volume and 3 g for fat-free mass. The limits of agreement between methods was +/- 75 ml for body volume and +/- 214 g for fat-free mass. Our results indicate that the acoustic method can measure a change in body volume of 75 ml and a change in fat-free mass of 214 g in a 2000 g infant.

AN - 78799574; 2484544 AB - In two fully crossed, two-factor experiments, F1 generation male rats were fed a basal diet supplemented with lead (lead acetate) at 0 or 2 micrograms/g and iron (ferric sulfate) at 50 or 250 micrograms/g (Experiment 1). Supplements in Experiment 2 were lead at 0 or 1 micrograms/g and iron at 50, 250, or 1000 micrograms/g. After 28 or 50 d in Experiment 1, and 35 d in Experiment 2, a relationship between lead and iron was found. Body weight was lower in low-lead than lead-supplemented 28-d-old rats regardless of dietary iron, whereas hematocrit and hemoglobin were lower in low-lead than lead-supplemented rats fed 50 micrograms iron/g diet. A similar finding was obtained with hematocrit and hemoglobin in 35-d-old rats. Dietary lead did not affect rats fed 250 or 1000 micrograms iron/g diet. Also, feeding low dietary lead did not affect 50-d-old rats regardless of dietary iron. Liver and bone concentrations of lead were markedly affected by dietary lead and iron. The concentration of lead in liver and bone was lower in low-lead than lead-supplemented rats. Compared to rats fed 50 micrograms iron/g diet, rats fed 250 micrograms iron/g diet exhibited a decreased lead concentration in liver and bone. This decrease was accentuated by lead supplementation. The findings suggest that lead acted pharmacologically to affect iron metabolism in rats.

In analyzing data from the 1983 Survey of Consumer Finances (N = 3,509 families), using this new income/wealth measure caused numerous shifts in the location & demography of the poverty population, as compared to that identified using the conventional measure. Among those more often found to be in poverty under the new measure were young, renter, & large central city resident households. Age, homeownership, farm employment, education, retirement status, public assistance participation, & residence in the West were important factors in explaining the divergence of the conventional & modified measures. The age & retirement impacts were significantly different in rural & urban areas, but rural residence itself was not an important factor in explaining differences between the two measures. 6 Tables, 3 Figures, 11 References.

AN - 78395900; 3413020 AB - Salmonellosis, a common human intestinal disorder primarily caused by Salmonella-contaminated meats and poultry, was estimated to cost Americans around one billion dollars in 1987. Only medical costs and productivity losses were included in the estimate of costs of the two million cases estimated to occur annually. If pain and suffering, lost leisure time, and chronic disease costs could be easily quantified, the estimate would increase significantly. Other procedures for calculating the value of life could change the estimates of economic benefits of reducing human salmonellosis. Incorporating losses to farmers, whose animals have reduced feed efficiency, reduced weight gain, or deaths because of chronic salmonellosis, would increase the size of estimates. Costs of food safety regulatory programs and costs to the industry for product recalls and plant closures due to foodborne salmonellosis outbreaks, if included, would also increase the size of estimates. The National Academy of Sciences has endorsed risk assessment as a necessary method for evaluating and improving food safety regulatory programs, especially as applied to Salmonella contamination of poultry. This report reviews and updates research on cost estimates of salmonellosis. Understanding the costs of salmonellosis is an important part of risk assessment, as a key objective of regulatory programs is reducing human salmonellosis.

AN - 78388494; 3413021 AB - Recent publicity about Salmonella contamination in poultry and the report of the National Research Council (NRC) on poultry inspection have focused public attention on the problem of microbial contamination in commercially processed poultry. Despite the public perception that such contamination is a relatively new phenomenon, benchmark studies over the years indicate this is not the case. New solutions to the problem have been suggested by the NRC and others, but the fundamental nature of the problem has remained the same. Food Safety and Inspection Service programs to deal with the problem will need to be supplemented by efforts by other agencies and the industry and consumer sectors if significant public health gains are to be achieved.

AN - 78334966; 3400928 AB - To study the distribution of tissue cysts in porcine tissues, 16 pigs were fed oocysts of 4 strains of Toxoplasma gondii (4 pigs/strain). Pigs were euthanatized between postinoculation days 103 and 875 and portions of 5 to 14 organs were bioassayed in mice and/or cats for T gondii. For bioassays, 50- to 100-g portions of tissue were incubated in acidic pepsin solution to free bradyzoites from cysts in parenchyma, and washed sediment from the digests of each specimen was inoculated SC into mice (6 mice/organ). For bioassays in cats, a 500-g portion or whole organ was fed to Toxoplasma-free cats (1 cat/organ). Toxoplasma gondii was recovered from tissues of 14 of the 16 pigs (from the brains of 12, hearts of 11, tongues of 10, and diaphragms of 6). Toxoplasma gondii was isolated from commercial cuts of meat from 5 infected pigs; from the arm picnic and ham of 3, Boston butt, spareribs, and tenderloin of 2, and bacon and tailbone of 1. Regarding the 4 pigs euthanatized between postinoculation days 759 and 865, cats shed T gondii oocysts after the ingestion of hearts of all 4; tongues of 3; bacons, hams, arm picnics, Boston butts, spareribs, and diaphragms of 2; and livers, kidneys, and tenderloins of 1. Toxoplasma gondii was found to be inconsistently distributed among the organs and muscles, but overall, tongue and heart were more heavily infected than were other tissues. Tissue cysts in pork were rendered nonviable at -12 C for 3 days.

AN - 78307590; 3388746 AB - Selected case reports from closely controlled experimental feedings of Senecio jacobaea (tansy ragwort), S longilobus (threadleaf groundsel) and S riddellii (Riddell's groundsel) to cattle are presented to show that all 3 of these pyrrolizidine alkaloid-containing plants may not necessarily induce proximate toxicity, but may cause typical signs and death many months after the plants are ingested. Results of the experimental intoxications indicate that if the daily dosage is of sufficient size to insult hepatocytes, a chronic lethal dose of plant may be eaten in only a few days. Early signs of intoxication may be absent, or mild and transitory, and serum enzyme changes that reflect liver injury may not always be detectable. Latent pyrrolizidine alkaloidosis signs can develop many months after the plants are eaten, and death imminent soon thereafter. The prepatent period and eventual time of death appears to be dependent on the time-dose relationship that determines the rate of progressive hepatocellular injury.

AN - 78309732; 3134339 AB - A method was developed specifically to detect naturally occurring Listeria monocytogenes in meat because the traditional cold enrichment procedure was extremely slow and other procedures were ineffective. This method could identify beta-hemolytic Listeria colonies in 3-4 days. The use of a 2-stage enrichment, highly selective LPM agar, and a thin-layer horse blood agar plate for the detection of beta-hemolytic Listeria isolates are the important steps of this method. L. monocytogenes was recovered from 20 of 41 samples of frozen ground beef, 12 of 23 samples of pork sausage, and 7 of 22 samples of poultry. These results indicate that L. monocytogenes is common in raw meat and that this method is effective for its recovery.

AN - 78184587; 2452215 AB - An extract prepared from newborn calf thymus stimulated proliferation of human keratinocytes cultured from newborn foreskins and from skin biopsies of 26 adult volunteers aged 19 to 70 years. Growth over the 7-day assay period in the basal medium was age-dependent, with newborn cultures achieving a 10-fold increase in cell number over seeding density, old adult cultures barely maintaining their seeding density and young adult cultures intermediate in proliferative capacity. Maximally stimulatory extract concentration was 5-fold higher for newborn than for adult keratinocytes, with adult cultures experiencing toxicity at doses still growth-promoting for newborn cultures. At optimal extract concentration the maximal average increase in cell yield (66.3% for newborn, 53.6% for young adult, and 18.1% for old) indicated decreased mitogen responsiveness or increased inhibitor sensitivity with increasing donor age. Stimulation of cholera toxin-treated cultures was equally high, ranging from 39.4% to 145.9%, suggesting that the extract acts through a cyclic AMP-independent pathway. Thymic extract did not increase colony forming efficiency. Our findings provide further support for the concept of functional interactions between the skin and the immune system, in addition to the recognized morphologic similarities between thymic cells and keratinocytes. Furthermore, these data confirm earlier findings of an inverse relationship between mitogen responsiveness and donor age for cultured cells.

Cracks extended to the foundation and had openings to 4 cm wide and frequently at 2 m intervals. Seepage through this cracked embankment was studied in four rectangular cells built within the reservoir. Two of the cells were test embankments in repaired conditions, one was in an unrepaired condition and the fourth had an impervious geomembrane in place along the downstream trench face. Piezometers were installed in each cell at locations of known cracks. After piezometer placement, the cells were filled for 30 days. The seepage within the cracks of this embankment was self healing and little or no advance of the phreatic line occurred. The cracked embankment appears to be safe against seepage and subsequent failure. (Stoehr-PTT) JF - Transactions of the ASAE TAAEAJ Vol. 31, No. 3, p 701-705, May-June 1988. 10 fig.

Each of these latter coefficients was then divided by the appropriate subregional on-farm irrigation-efficiency-percentage coefficient to obtain the average per-acre irrigation consumptive use for the groundwater-mining subregions. These consumptive-use rates were then multiplied by the corresponding acreages within each groundwater-mining subregion to obtain the acre feet of groundwater used in 1982. Single-year estimates of water-decline irrigated acres greatly improve the foundation for estimating certain annual-basis values useful to managers of agribusiness firms and to public decision makers. Among these annual-basis values are acre feet of water consumed and amounts of pesticides and fertilizers applied. Especially important to federal decision makers concerned with influencing farm-production decisions would be a continuing series of annual-basis estimates revealing the trend of irrigated production as it depends on declining water supplies.

AN - 78248594; 3377307 AB - Two lactating Nubian goats were dermally treated with [14C]coumaphos (O-[3-chloro-4-methyl-2-oxo-2H-benzopyran-7-yl] O,O-diethyl phosphorothioate) as a 4% active ingredient pour-on formulation. Doses were administered, along the dorsal midline from withers to sacrum, at a rate equivalent to 14 mg of coumaphos/kg of body weight. During the 7 days after treatment, an average of less than 0.1, 4.7, and 1% of the administered dose was eliminated in the milk, urine, and feces, respectively. When goats were killed after 7 days, about 45% of the administered radiocarbon remained on the hair and skin, and this consisted almost entirely of intact coumaphos. Residues in selected tissues collected after 7 days were, in every case, less than 1 mg of coumaphos equivalent/kg of tissue, with highest residues in adipose tissue, followed by residues in kidney and liver. In milk, residue amounts plateaued after about 2 days and remained relatively constant at about 0.1 mg of coumaphos equivalent/kg of milk. Residues in adipose tissue and in milk consisted mainly of unmetabolized coumaphos. In urine, most radiocarbon was present as metabolites of coumaphos, but in feces, most radiocarbon was present as the intact parent compound. Coumaphos was absorbed slowly and at a constant rate after dermal application to lactating goats as a pour-on formulation.

Any effective regulations to ban or restrict agricultural chemical or land use practices in order to improve water quality will affect the farm economy. Some farmers will benefit; some will not. Most agricultural pollutants reach surface waterways in runoff; some leach through soil into groundwater. Because surface water systems and groundwater systems are interrelated, farm management practices need to focus on water quality in both systems. Modifying farm management practices may raise production costs in some areas. Farmers can reduce runoff losses by reducing input use, implementing soil conservation practices, and changing land use. Also at issue is who should pay for improving water quality; farmers, governments, consumers, or those who benefit from improved water quality.

Matching the amount and timing of nutrient applications to the needs of crops is the most cost-effective and efficient way to control nutrient contamination of surface and groundwater. Soil conservation practices reduce surface-water pollution, but can increase nitrate leaching through the soil. Misdirected practices, such as excessive or mistimed manure applications, can increase nutrient contamination of surface and groundwater. A field-scale computer simulation model, CREAMS (Chemicals, Runoff, and Erosion from Agricultural Management Systems) was used to assess pollutant losses from agricultural land to water. A central theme of the analysis is the tradeoff between nutrient loadings in surface water versus groundwater.

AN - 78279132; 3384765 AB - On Mueller Hinton (MH) agar, Campylobacter jejuni showed 20.0 and 30.9 mm zones of inhibition surrounding discs impregnated with 2.5 and 20 micrograms CdCl2 respectively. The minimal inhibitory concentration (MIC) ranged from 0.64 to 3.2 micrograms CdCl2/ml of MH agar for four C. jejuni strains. In the presence of 23 micrograms FeSO4/ml of MH the MIC increased to a range of 1.5-5.4 micrograms CdCl2/ml of MH. Moreover, the numbers of colonies present on MH supplemented with FeSO4 were greater than on MH without iron. The growth response of C. jejuni in the presence of 0.025% (w/v) FeSO4 in MH broth was increased about 10,000 fold in three of four strains when compared with the growth in unsupplemented MH broth. Zones of inhibition surrounding 20 micrograms discs of CdCl, were 50.6 and 24.4 mm on MH and Campy-BAP media respectively, with cells grown on MH. These results suggest that the blood-containing medium 'neutralized' the biocidal influence of the CdCl2. In comparison, C. jejuni inoculum from fluid thioglycollate (FT) medium showed smaller zones of inhibition. These decreased from 34.9 mm on MH agar to 19.6 mm on Campy-BAP agar, suggesting that components in the FT growth medium ameliorated the toxic influence of CdCl2. Atomic absorption spectroscopy analysis indicated mean values (mg/100 g dry weight) of selected metals bound by C. jejuni as: Cu, 10.4; Mg, 146; Na, 2385; Fe, 45.1; Zn, 13.0; and K, 172.

AN - 78139623; 3351635 AB - Weight gains in mice fed amino acid diets containing methionine and 16 methionine derivatives and analogs were compared at graded dietary concentrations. Linear response was closely approximated for concentrations below those yielding maximum growth. Derivatization of L-methionine generally lowered potency, calculated as the ratio of the slopes of the two dose-response curves. However, the three isomeric dipeptides L-L-, L-D- and D-L-methionylmethionine, N-acetyl- and N-formyl-L-methionine, L-methionine sulfoxide and D-methionine were well utilized. The double derivative N-acetyl-L-methionine sulfoxide reduced potency below 60%. D-Methionine sulfoxide, N-acetyl-D-methionine and D-methionyl-D-methionine had potencies between 4 and 40%. The calcium salts of L- and D-alpha-hydroxy analogs of methionine had potencies of 55.4 and 85.7%, respectively. Several of the analogs were less growth-inhibiting or toxic at high concentrations in the diet than was L-methionine. These results imply that some methionine dipeptides or analogs may be better candidates for fortifying foods than L-methionine. Possible biochemical pathways for the utilization of methionine derivatives and analogs are also described.

AN - 78126403; 3279098 AB - Copper is known to be an essential nutrient for human beings, but a Recommended Dietary Allowance has not yet been established. A safe and adequate range of intake was established in 1980 for copper and five other trace elements. The range for copper, 2 to 3 mg/day, is higher than the usual dietary copper intake of many individuals in this country. On the basis of balance studies, a requirement of 1.3 mg/day has been suggested. Recent data on copper intake and bioavailability should aid in reevaluating the dietary copper requirement. Copper deficiency symptoms have seldom been observed in human beings. When copper deficiency has been recognized, it has been under unusual conditions, such as in patients receiving parenteral nutrition. Interactions between copper and other dietary components may alter copper status, but the impact of those interactions is not yet well understood. Dietary factors that may affect the bioavailability of copper include the levels of copper, zinc, and molybdenum in the diet; iron deficiency; ascorbic acid intake; intake of carbohydrates, including fructose, glucose, and starch; and fiber and phytate intakes. Some drugs may also affect copper bioavailability.

Although current enrollment is limited to highly erodible soils and stream buffers, salinity is cited as one of several criteria which may be used to determine future cropland eligibility. Extending CRP eligibility to highly saline irrigated soils has an effect on acreage enrollment, water quality, production control, and program cost. Modification of program eligibility criteria to include irrigated saline croplands will not significantly expand the national acreage pool, although local effects may be important. Potential new enrollment is limited by additional eligible acreage, county enrollment ceilings, and enrollment incentives for irrigated lands. Offsite water quality benefits attributable to reduced salt-loading may be very significant. However, enrollment of irrigated saline cropland is less cost-effective than currently eligible cropland from a commodity supply perspective. State involvement in support of a CRP salinity provision is likely to increase program effectiveness.

Although the CRP retired only highly erodible cropland in its first two years, other environmental problem cropland could gain CRP eligibility at the discretion of the Secretary of Agriculture. Stream buffers, which became eligible in 1988, are expected to provide much higher water quality benefits per acre than highly erodible acres. Enrolling saline, irrigated cropland would, however, produce higher off-site benefits only in certain river basins. Addressing groundwater mining through the CRP would result in much lower off-site benefits per acre than highly erodible acres currently enrolled. CRP rental payments for both surface and groundwater irrigated cropland would also be relatively high. The recent CRP changes and proposals being considered by Congress are increasingly focused on local water quality problems and can increase the overall environmental benefits from the program. Additional changes under consideration could in some instances also increase these benefits, but would affect other CRP program objectives, such as supply reductions and program costs. Only wet croplands appear to offer substantive potential for expanding the CRP unless program costs per acre enrolled are allowed to increase.

The primary problem is surface water and groundwater contamination by agricultural chemicals through leaching, rainwater runoff, or soil erosion. A recent study of groundwater in the U.S. estimated that about 1,400 counties (of 3,000 studied) showed the potential for either nitrate contamination, pesticide contamination, or both. Another study of freshwater systems showed that 48 of 90 watersheds were found to have excessive levels of nutrients or sediment caused by agriculture. For most types of water pollution, especially chronic conditions like excessive levels of nutrients and high concentrations of pesticides and other farm chemicals, the most significant coastal effects are usually found in estuaries and bays. The degradation of water quality from agricultural residuals results in an economic cost of several billion dollars annually. Three principal costs of groundwater contamination are health impacts, informational costs, and remedial costs. The social costs of human exposure to chemicals in groundwater are not yet known. A variety of federal, state, and local laws provide a legal or administrative basis for addressing the problem of agricultural nonpoint source pollution of surface and groundwater. Programs and policies to manage and control the impact of agriculture on U.S. water resources encompass many objectives and must involve tradeoffs among conflicting needs; the goals of environmental protection and enhancement of water quality may at times conflict with other social goals such as ensuring profitable food and fiber production.

There has been some uncertainty about the reduction in water use forthcoming from the imposition of a tax. Present water demand analysis using water use and pumping cost data from 1,927 farms sampled by the Farm and Ranch Irrigation Survey, found only modest water savings per acre from the imposition of a pumping tax. This lack of responsiveness held true for both Nebraska, a state that only partially depends on irrigation, and for New Mexico, where farmers depend more heavily on irrigation. The lack of water conservation can be partly attributed to the relative unresponsiveness of adoption of water saving technologies, such as sprinkler irrigation, to the cost of water.

Past uses of consumptive use estimates are contrasted with needs to address water resource issues in the current and future decision making environment. Public policy analysts may have problems using consumptive use estimates that were developed for use by irrigation developers and irrigated producers, who have historically required increasing absolute accuracy for a small geographic area. Point accurate estimators most appropriate for historical uses are not well suited to public policy analysis which is broader in geographic coverage and focuses on relative change due to policy action. Current estimation methods have also supplied consumptive use estimates for on-farm water management information. These techniques have focused correctly on developing increasingly precise estimates for a shrinking geographic area.

Persons (farmers) who convert wetland and plant annual crops lose eligibility for certain U.S. Department of Agriculture (USDA) program benefits. Swampbuster is proving to be effective in North Carolina for protecting wetlands. With a depressed farm economy, farmers need USDA farm support, storage loans and commodity payments, etc., to survive; therefore they cannot afford to clear land that meets the wetland criteria of the 1985 Farm Bill and lose their USDA program benefits. From a farmer 's perspective, a lot of land that isn t very wet is considered wetlands. Land that was once considered as potentially good cropland can no longer be converted. This is having a significant impact on the price of undeveloped land and will affect the value of farms. (See also W90-10584) (Author 's abstract) JF - Coastal Water Resources.

After an initial growth period (21 days), plants were exposed to cycles of severe, moderate, or no drought stress over a subsequent 28-day period. Dry weights of fungus-inoculated plants were greater at severe stress and smaller at no stress than those of uninoculated plants. Phosphorus fertilization was applied to produce inoculated and uninoculated plants of the same size at moderate stress. Root and leaf phosphorus were higher in uninoculated plants at all stress levels. All plants were stressed to permanent wilting prior to harvest. Inoculated plants had lower soil moisture content at harvest than uninoculated plants. Colonization of roots by G. mosseae did not vary with stress, but the biomass and length of the extraradical mycelium was greater in severely-stressed than in non-stressed plants. Growth enhancement of inoculated plants relative to phosphorus-fertilized uninoculated plants under severe stress was attributed to increased uptake of water as well as to more efficient phosphorus uptake. The ability of inoculated plants to deplete soil water to a greater extent than uninoculated plants suggests lower permanent wilting potentials attributable to fungus inoculation.

AN - 78797178; 2475130 AB - Disulfide bonds of bovine serum albumin and wool were reduced by n-tributylphosphine to sulfhydryl groups that were then modified by methyl or ethyl vinyl sulfone in a nucleophilic addition reaction to S-(beta-ethylsulfonylmethyl)-L-cysteine and S(beta-ethylsulfonylethyl)-L-cysteine, respectively. The reductive alkylation was carried out either simultaneously, with both the reducing and alkylating agents present in the reaction mixture, or sequentially, with the reduced proteins first isolated before alkylation. Amino acid analysis studies showed that authentic, synthetic S-(beta-ethylsulfonylethyl)-L-cysteine eluted as a well-resolved peak after serine but that the peak associated with the corresponding methyl derivative overlapped the corresponding peak due to threonine. The extent of alkylation of the sulfhydryl groups of cysteine, epsilon-NH2 of lysine, and NH groups of the imidazole ring of histidine was also measured by amino acid analysis. The results show that alkyl vinyl sulfones have a strong chemical affinity for protein functional groups.

AN - 78544753; 3194655 AB - Greened or sprouted potatoes contain increased concentrations of steroidal alkaloids that have caused intoxication and death in a wide variety of animal species, however, the cause of death in these animals has not been determined. Potato alkaloids can cause death when parenterally administered, and is attributed to the acetylcholinesterase inhibitory activity of solanine and chaconine. To determine the cause of death in animals ingesting potato sprout material, 40 Syrian hamsters were divided into 4 equal groups and gavaged once on day 0 either water, 300 mg of potato sprout material, 400 mg of potato sprout material, or 500 mg of potato sprout material. Tissues were examined grossly and microscopically at 72 hr post-gavaging and brain acetylcholinesterase activity of each hamster was measured. The 300-mg dose group had increased mean acetylcholinesterase activity compared with control hamster mean activity, and the 400-mg and 500-mg dose groups had 90% and 84% of the mean acetylcholinesterase activity of the control hamster mean activity. There was severe gastric and proximal small intestinal mucosal necrosis in those hamsters which died prior to euthanasia. Additionally, several hamsters had valvular endocarditis and infarcts. Death could not be attributed to the slight acetylcholinesterase inhibition in the 2 higher dose hamster groups and was related to the severe gastrointestinal necrosis which occurred in hamsters of these groups.

AN - 78508797; 3185013 AB - Studies were done to ascertain whether dietary magnesium, manganese and boron affect the response of the rat to high dietary aluminum. Four factorially arranged experiments of 7 weeks duration were performed with weanling Sprague-Dawley male rats. The variables were the following supplements (microgram/g fresh diet): boron as boric acid, 0 and 3; aluminum as aluminum chloride, 0 and 1,000; and magnesium as magnesium acetate, 100 and 400 (experiments 1 and 4) or 100, 200 and 400 (experiments 2 and 3). In experiments 1 and 2, the diet was supplemented with 20 micrograms manganese/g as manganese acetate, in experiments 3 and 4 the supplement was 50 micrograms/g. High dietary aluminum seemed most toxic when dietary magnesium was low enough to cause a marked growth depression (100 micrograms/g). High dietary aluminum elevated the spleen weight/body weight and liver weight/body weight ratios in magnesium-deficient, but not in magnesium-adequate rats. High dietary aluminum depressed the concentrations of magnesium in bone more markedly in magnesium-deficient than adequate rats. On the other hand, aluminum seemed most toxic when dietary boron was not low. Aluminum more markedly depressed growth in boron-supplemented than boron-deprived rats. In the boron-deprived rats fed 400 micrograms magnesium/g of diet, high dietary aluminum (1,000 micrograms/g) apparently was beneficial, in experiments 2 and 3, hematocrit, and hemoglobin were actually normalized by high dietary aluminum. Plasma magnesium was significantly depressed by high dietary aluminum when the manganese supplement was 50 micrograms/g diet but not when it was 20 micrograms/g diet. On the other hand, growth was more markedly depressed by high dietary aluminum in boron-supplemented rats when the manganese supplement was 20 rather than 50 micrograms/g diet. The findings indicate that the response of rats to high dietary aluminum is influenced by magnesium, boron, and manganese nutriture.

AN - 78475282; 3176049 AB - We developed a colorimetric assay for determining metabolic activity (viability) of cells exposed to toxic agents. This system is based on the ability of mitochondrial enzymes in viable cells to modify a tetrazolium salt into a blue formazan product that can be detected spectrophotometrically at 570 nm. The assay works equally well for mammalian and insect cell lines and at 48 hr color formation is linear over a cell input range of 1.56-50 X 10(4) cells/ml. The inhibitory effects of T-2 mycotoxin on tetrazolium cleavage in L929 cells is comparable to that observed for protein and DNA synthesis (50% inhibition = 6-8 ng/ml). Using this system to analyze the lethal effect of T-2 toxin on cells from various animal species, it was found that bovine cells were the most sensitive (50% inhibition at 2.2 ng/ml) while hamster cells were the most resistant (50% inhibition at 26.2 ng/ml). Murine cells exhibited intermediate sensitivity (50% inhibition at 10.9 ng/ml). Variable toxin susceptibility was also observed among different cell types. Lymphocytes were 3-fold more sensitive to the T-2 inhibitory effects than comparable tissue culture cell lines. These data indicate that the colorimetric assay system could have broad applications in toxicological studies. Further, the observed differences in species sensitivity may provide insight into the primary mechanism of the T-2 toxin-cell interaction that ultimately leads to cell death.

Fetal movement was observed by radio ultrasound at 45, 54 and 60 days of gestation in control ewes and on days 45, 54, and 60 of gestation immediately before and 1 hour following poison-hemlock feeding in treated ewes. Fetal movement was significantly reduced (P less than 0.01) 1 hour after poison-hemlock administration, but returned to normal within 18 hours post treatment. At parturition seven of eleven lambs born to seven treated ewes had varying degrees of front limb abnormalities. Modest to moderate flexure of the carpal joints, some lateral deviation in the front limbs at the pastern joint and kinked tails were observed. These malformations were transient and resolved spontaneously by 8 weeks after lambing. JF - Journal of toxicology.

AN - 78164180; 3281829 AB - Cigarette smoke contains carcinogens and mutagens and affects the health of smokers. Recently, increased research has proven the potentially protective activity of selenium (Se) against heavy metal toxicity, cancer, and other health disorders. Accordingly, we have proposed the fortification of tobacco with Se to develop safer cigarettes. As a start in evaluating any biological effects of added Se, we have determined the mutagenicity of inhaled, mainstream (MS) cigarette smoke condensate (CSC), with and without Se, in the preincubation assay of the Ames test. Initially, it was shown that Se, as sodium selenite, was not mutagenic at high concentrations (up to 80 micrograms/plate) with strains TA1538 and TA1978. Subsequently, the effects of different levels of Se, added to MS CSC, were examined with TA98, TA100, and TA1538. On the average, addition of 10 micrograms Se produced mutagenicity reductions of about 50%. Higher levels of added Se yielded further reductions. Cigarette sidestream (SS) smoke, collected between puffs, was also tested. Again, Se added to SS-CSC gave similar reductions, confirming its antimutagenic effect for both mainstream and sidestream smoke.

The mutagenic potencies of a prototype agent of each class, quercetin (3,3',4',5,7-hydroxyflavone) and norwogonin (5,7,8-hydroxyflavone), were determined in tester strains differing in excision-repair capability and in the presence or absence of plasmid pKM101. Two series of strains were used, one with the hisD3052 frameshift mutation and one with the hisG46 missense mutation. With both agents and for both series of strains, the mutagenic response was markedly dependent on the absence of excision repair and the presence of the pKM101 plasmid.

AN - 78119801; 3345079 AB - Aflatoxin concentrations in agar media were estimated with a direct technique that quantifies the fluorescence of agar containing aflatoxins. Tubes containing 5 ml of an agar medium inoculated with spores of aflatoxin-producing Aspergillus isolates were incubated for 3 days at 30 degrees C and set in a carriage specifically designed to carry culture tubes in a scanning densitometer. Fluorescence (450 nm and above) was elicited in the agar by UV light (365 nm) and photometrically measured. Agar fluorescence directly correlated (r2 = 0.89 +/- 0.05, P less than 0.001) with the concentration of aflatoxin within the range 0 to 18.7 micrograms/g. The lowest aflatoxin concentration detected was 50 ng/g. The technique successfully differentiated the aflatoxigenic potentials of Aspergillus isolates.

AN - 78104924; 3344568 AB - Turbinate osteoporosis, induced by intranasal inoculation of purified toxin isolated from serotype D Pasteurella multocida, was investigated in 3- to 5-week-old, caesarean-derived, colostrum-deprived, isolation-reared pigs. Marked bilateral reduction in relative volume of trabecular bone occurred in osseous cores of turbinates of toxin-treated pigs relative to control pigs on post-inoculation day (p.i.d.) 3, 6, 9, 12, and 15. The fractional resorptive surface along turbinate bone was greater in toxin-treated pigs when compared to controls on p.i.d. 3 and 6. A significant decrease in resorptive surface occurred over time in toxin-treated pigs, whereas the fractional resorptive surface was constant over time in control pigs. Osteoclasts in medullary spaces separating bony trabeculae of turbinates were abundant in toxin-treated pigs and scant in controls on p.i.d. 3, 6, and 9. Degeneration and necrosis of bone forming cells, principally osteoblasts, were progressively more extensive with time and were associated with decreased mineralization and reduced thickness of osteoid and woven bone matrix. Osteoclasts along resorptive surfaces of turbinate bone in toxin-treated pigs had more abundant, more highly vacuolated cytoplasm, a more prominent microvillous border, and a greater number of nuclei per cell than osteoclasts from control pigs on p.i.d. 3 and 6. We conclude that this Pasteurella toxin stimulates osteoclastic osteolysis and inhibits osteogenesis in turbinates by causing degeneration and death of osteoblasts.

This distortion has little influence on orbital interactions within the frame. These effects can be traced to next-nearest-neighbour, oxygen-oxygen interactions. The interactions between Si(3s,3p) and O(2s) atomic orbitals account for half the bonding overlap in the Si-O bond. Crystal orbitals within the 066 (super 2) (sub infinity ) (Si (sub 2) O (sub 5) (super 2-) ) frame are perturbed in these phyllosilicates through interactions of the apical oxygens with octahedrally coordinated Al(III) and Mg(II) . These interactions appear to involve states that are non-bonding in an isolated frame having little effect on the Si-O (sub apical) bond while significantly reducing the apical oxygen atomic population.

Well-water quality generally improved with increased well depth and with natural geologic protection related to thickness of overlying bedrock or Quaternary aquitards. Nitrate levels were highest in areas where sinkholes were present; areas without sinkholes but with relatively thin protective cover had similar but somewhat lower levels of nitrate. A detailed analysis of a single karst groundwater basin found the same systematic nitrate contamination along with low but persistent levels of herbicides. Agricultural practices were judged to be the source of the contaminants and infiltration was the principal mechanism. Ninety-five percent of the nitrate and 55 to 85% of the atrazine were delivered by infiltration and percolation. Various state and Federal agencies, university researchers, local groups, and private organizations are cooperating in a seven-year project in the Big Spring basin to demonstrate and evaluate the effectiveness of best management practices on groundwater quality and on crop production. The project will provide research results to serve as a foundation for future policies and programs that agriculture must address relative to environmental problems.

Principles of soil and water conservation consist of increasing infiltration to furnish water for plant use instead of contributing to runoff. This can be done by covering the soil with living or dead vegetation to slow runoff or stop runoff with terraces or contoured ridges and storing that runoff until it infiltrates. In order to be successful programs must demonstrate the advantages of the changes to the farmers. Comparative field trials established by the land owners on their own land have been very effective. On cropland, level bench terraces, level ridging of contour rows, mulching, and gully plugs have been successfully tested and demonstrated. On grassland, practices that proved effective were natural seeding, short-duration grazing, small infiltration ditches, watering holes, and gully plugs. For existing trees and for establishing any type of new tree crops, terraces, natural seeding, level absorption ditches, residue management, and gully plugs proved adequate. These methods have produced substantial increases in yields of 42 crops that were compared. (See also W92-11761) (White-Reimer-PTT) JF - IN: Conservation Farming on Steep Lands.

Because of the radioactive properties of these contaminants, there is growing concern that accumulation of these greenhouse gases will contribute to global warming and other adverse changes in climate. There is also concern that decreases in stratospheric ozone concentration will increase the level of biologically effective radiation in the 28-320 nm (UV-B) region. Such changes in the atmosphere could have a significant impact on production of crops and natural ecosystems. Single and multiple-factor studies are needed to assess the agricultural impact of increased levels of CO-2, air pollutants, UV-B radiation, drought, and high temperature stress and to determine the mechanisms of tolerance or adaptation to these stress factors. Policy options available to reduce emissions of green house gases include making changes in energy production and use, developing environmentally safe substitutes, altering methods for agricultural production, increasing reforestation, and changing land management practices. Any overall solution will require international cooperation among many nations and significant reductions in many sources.

The Soil Conservation Service (SCS) was established in 1935 and became the technical or engineering arm of the U.S. Department of Agriculture (USDA). Water resources and flood plain management activities came with the realization that flood runoff could be reduced by dealing with the water where it falls on the land rather than where it runs off downstream. The SCS has become involved in watershed protection, flood prevention, erosion control, flood control, and has cooperated with other federal, state, and local agencies to train specialists in hydrology and hydraulics. Some obvious concerns when looking at the SCS 's ability to participate in flood plain management are appropriated funds, development on flood-prone lands, and changing economic and environmental conditions. Priority will continue to be given to studies that identify areas where flood damages are increasing and that focus on cost-effective solutions to reduce damages, including structural and nonstructural alternatives. The SCS plans to shift more resources into their Flood Plain Management Studies, geared to help local, upstream communities identify their flood hazards and to evaluate cost-effective solutions. The SCS also plans to provide technical assistance to rural communities in storm water management. Efforts must be intensified to work more closely with other agencies to achieve common goals.

AN - 15969730; 2549770 AB - A distinctive foliar chlorosis of soybean, Glycine max (L.) Merr., has been traced to nodulation by certain strains of bradyrhizobia that produce the substance rhizobitoxine in the root nodules. Strains of Bradyrhizobium nodulating soybean have been classified into three groups by relative DNA homology. To define the possible relationship between chlorosis induction and DNA homology group, 25 bradyrhizobial strains identified by DNA homology group were tested for chlorosis induction on the chlorosis susceptible soybean line N53-3494. Five of the nine strains examined in Group 2 produced chlorosis symptoms in this test. Of the four remaining strains one was previously reported by another investigator to produce mild chlorosis symptoms and another strain was reported to produce rhizobitoxine in vitro.

AN - 15853553; 2452306 AB - Fire is an ecosystem property rather than an exogenous force in southern California chaparral, and it interacts with processes of drought-mediated canopy development, production, and mortality to affect stability of community composition. Where species that must reproduce from seed, such as Ceanothus crassifolius or Ceanothus oliganthus , are predominant, composition can be altered by a single fire with little or no recruitment after initial postfire establishment. Water balance apparently regulates subsequent leaf area development; after 15-22 yr of postfire growth, foliage biomass in monospecific C. crassifolius stands in this study had approached a maximum that was unrelated to incident solar radiation and insensitive to initial population density over a 10-fold range. Thus, establishment success, above that required for canopy closure, should have little effect on the foliage biomass that sustains combustion.

AN - 15844862; 2437330 AB - A population outbreak of Wahweap milkvetch (A. lentiginosus var. wahweapensis Welsh) occurred in the Henry Mountains area of southeastern Utah in 1985 and 1986, causing extensive locoweed poisoning in cattle grazing these winter ranges. Weather conditions supporting this population outbreak included above average precipitation in the fall of 1984 and 1985, which presumably allowed germination of seed lying dormant in the soil. Above average spring precipitation in the subsequent year supported the population growth. Part of the population died in the summer of 1985, and nearly all plants died in the summer of 1986. Historically, population outbreaks occurred every six to eight years: 1949, 1957, 1965, 1973, 1979, and 1985-1986. Correlation with weather records indicated that population outbreaks occurred in years of high spring and total annual precipitation. Wahweap milkvetch seed lying dormant in the soil ranged from 940 to 4,346 seed/m super(2) where old stands occurred, and 20 to 40 seed/m super(2) where old plants were not evident.

Flight traps (or wing traps) collected the most specimens but represented the fewest species; this method was not recommended because of difficulty in removing specimens from adhesive. Water traps amassed the next largest number of specimens and the most species. The weekly collections from pitfall traps between the sites were significantly different (P < .05) in number of specimens and species. Malaise traps were the most convenient. Black Malaise traps collected more specimens and species than white malaise traps, although this difference was not significant. JF - Great Basin Naturalist AU - Hansen, J D AD - Trop. Fruit and Veg.

Tree canopy cover decreased significantly between 1977 and 1985, but changes in density of trees and shrubs and herbaceous cover were small. Exclusion of cattle use did not prevent channel erosion or deterioration of vegetation; rather, changes were attributed to a wildfire in the headwaters and subsequent storm events that temporarily upset the dynamic equilibrium of the steam.

Dewey, was examined on a field site in northern Utah in 1985. With egg hatch beginning in April, the bug completed its life cycle within two months. Ovarian development was completed by 11 June, a week after all bugs had become adults. The proportion of feeding damage per leaf (35.1%) peaked on the seventh week of the twelve-week study (18 July). Green leaf area per tiller decreased initially from bug feeding and then continued to decrease because of seasonal aging. All plants senesced within three months. Grass bugs predominantly attacked the second and third youngest leaves. Analyses of age-specific leaf cohorts demonstrated that the major effect on bug feeding was the loss of green leaf area and potential foliage production over time. Bug feeding may also exacerbate other physiological stresses on the host plants. JF - Great Basin Naturalist AU - Hansen, J D AD - USDA-ARS, Trop. Fruit and Veg. Res.

Because pretreatment data were not available, differences in macroinvertebrate populations and relative tolerances of taxa in grazed and ungrazed areas could be as easily attributed to linear changes in stream habitat as to removal of domestic livestock. Results of this study have implications for the design of future research on the effects of livestock grazing on stream environments and biota: (1) baseline/pretreatment information is prerequisite, and (2) the study should take a watershed (ecosystem) approach.

AN - 15726501; 2347864 AB - Two endangered native southwestern trouts (Salmo gilae and S. apache ) have been brought to a "secure" status through over three decades of intensive research and conservation efforts. Introductions of non-native salmonids and habitat loss and degradation forced these two natives into the extreme headwaters of their former range. Although well-adapted to survive at a small size ( 30 cm) in lakes and larger downstream waters. Monitoring of genetically pure populations, habitat enhancement-and most importantly-development of sport fisheries for both species are recommended goals for the future management and conservation of these two salmonids.

AN - 15722836; 2346538 AB - Comparison of abiotic and biotic variables that could influence trout populations in six headwater streams, central Arizona (USA) suggests that physical habitat strongly influences salmonid density and standing crop. Stepwise regression analysis indicated that stream depth explained most of the variation in density and biomass of trout (66 and 77%, respectively). Stream substrate explained 11 and 9% of the variation in trout density and biomass, respectively. Livestock grazing is suggested as a significant contributor to increased substrate fines (< 0.25) and reduced fish populations in several of these streams.

AN - 15660636; 2305438 AB - Recent field research has shown that ambient concentrations of ozone (O sub(3)) have the potential to reduce yield of a number of economically important crop species. Soil water levels have been shown sometimes to modify the extent of the reduction. The primary emphasis of most of these studies has been on the plant component that represents economic yield. Less emphasis has been placed on characterization of the effects of O sub(3) on growth of the total plant that ultimately determines yield. In this study, the authors measured season-long growth of field-grown cotton (Gossypium hirsutum) L. "McNair-235") that was exposed to a range of O sub(3) concentrations at two levels of soil moisture, well-watered (WW) and water-stressed (WS). The cotton was exposed for 12 h d super(-1) throughout the growing season in open-top chambers to five O sub(3) concentrations that ranged from 0.020 to 0.074 mu L L super(-1) (seasonal mean 12 h d super(-1) concentration).

AN - 15659338; 2305662 AB - Removal of soluble soil organic carbon (SSOC) during herbicide desorption studies using the batch equilibration method may affect the herbicide-soil-solution equilibrium particularly if herbicide-SSOC complexes can form. Desorption characteristics of atrazine (2-chloro-4-ethylamino)-6-isopropylamino-s-triazine) and cyanazine (2-{(4-chloro-6-(ethylamino)-s-triazine-2-yl)amino}-2-methylpropio nitrile) were determined in a Ves clay loam (Aquic Hapludolls). For adsorption, the soil was equilibrated with 0.01 M CaCl sub(2) each day for 5 d resulted in hysteresis when compared to the adsorption isotherm. Replacement of the equilibration solution with soil extract for 5 d, while maintaining a higher SSOC content in the desorption equilibration solution than did the CaCl sub(2) solution, did not change desorption isotherm equations. The SSOC-herbicide complexes were not detected in any of the adsorption and desorption equilibration solutions by ultrafiltration, HPLC, or TLC techniques.

AN - 15657909; 2305716 AB - Streamflow and water quality parameters were measured on five watersheds (262 ha-11 487 ha) of the Little River in the coastal plain near Tifton, GA. Concentrations of nitrate, ammonium, chloride, ortho-P, total P, total N, and electrical conductivity were determined. Loads and flow-weighted concentrations were calculated for the five watersheds and for six subwatersheds formed by subtraction of smaller watersheds from larger ones. Mean concentrations and total loads calculated from samples taken every 3 h were not significantly different from samples taken every 12 h on two watersheds. In general, nitrate was enriched and chloride diluted relative to baseflow during storm events. This was attributed to reduction of nitrate in soils and aquifers of riparian areas. Both nitrate loads and concentrations were decreased during low flow years, whereas chloride concentrations were significantly higher in a year with abnormally low flows. Ortho-P concentrations increased during storm events, but total P showed the opposite response. Enrichment of NO sub(3)-N and ortho-P and dilution of Cl and conductivity were due, in part, to concentrations in rainfall.

AN - 15657103; 2305458 AB - Plant response to ozone (O sub(3)) is known to be modified by soil moisture deficit, which occurs in varying degrees during most growing seasons. Thus, the authors examined the response of cotton (Gossypium hirsutum) L. "McNair 235") to different levels of seasonal stress by O sub(3) when grown at two soil moisture levels. The cotton was exposed for 12 h d super(-1) in open-top field chambers to five O sub(3) doses under well-watered (WW) conditions or under water-stressed (WS) conditions with periodic cycles of low soil moisture. Exposures began when the fifth leaves were expanding and continued for 124 d when most leaves where chlorotic or had abscised. Ozone caused significant yield loss in WW plots but not in WS plots. Based on estimates from polynomial regression analysis, ambient O sub(3) caused a yield decrease of 19% in the WW plots compared to the O sub(3) level in our charcoal-filtered air plots. The comparable estimate for data from the WS plot was 7%, but this regression was not statistically significant. Results indicate that soil moisture deficit can decrease the impact of O sub(3) on cotton yield.

Chicks were fed either unmedicated feed or one of five commercial broiler starter rations or nine experimental feed mixtures containing varying amounts and combinations of anticoccidial and antimicrobial medicaments. After 2 days, they were challenged with approximately 10 super(6) colony-forming units of a nalidixic-acid-resistant strain of Salmonella typhimurium). Six days later, chicks were sacrificed and ceca were analyzed for S. typhimurium . Colonization of 2-day-old chicks was prevented or at least greatly reduced in most instances by treatment of chicks with a CE culture, but the efficacy of CE broth cultures stored at -70 degree C diminished over time. Of the commercial or experimental feed tested, only the feed containing the combination of nicarbazin an bacitracin interfered with the protective effect of the CE culture.

AN - 15589908; 2241195 AB - A reproducible model of postweaning colibacillosis was obtained by controlling management and environmental variables to simulate conditions often seen at weaning. Suckling pigs were exposed briefly to starter diet at 1 week of age, weaned at 3 weeks of age, held at an ambient temperature of 20 plus or minus 2 C, and again given the starter diet. One day after weaning, each pig was given 10 super(10) colony-forming units of enterotoxigenic Escherichia coli strain M1823B (0157:K88ac:H43-LT super(+) STb super(+)) in broth containing 1.2% sodium bicarbonate via stomach tube. In vitro adhesion by strain M1823B to isolated intestinal branch borders was used to test pigs for susceptibility to K88. In this model, 3 syndromes were induced in susceptible pigs: (1) peracute fatal diarrhea; (2) moderate diarrhea, weight loss, and fecal shedding of the inoculum strain; and (3) no diarrhea, weight loss, and fecal shedding of the inoculum strain.

AN - 15584806; 2235871 AB - Spiders of 11 families, 22 genera, and at least 33 species were collected from crown foliage samples of Abies balsamea (L.) Mill., Picea rubens Sarg., and Picea glauca (Moench) Voss in east-central Maine. For both study years (1985, 1986), spider species composition varied by foraging strategy (web spinner, hunter) and among 10 study sites. Numbers, life stages, and sex ratios of spiders also differed between study years. Spider densities per m super(2) of foliage area generally were greater (P less than or equal to 0.05) on spruces (X super(-) = 16.3 plus or minus 1.1) than on fir (X super(-) = 10.9 plus or minus 1.0). Estimates of absolute populations of arboreal spiders ranged from 35,139 to 323,080/ha; of spruce budworm from 271,401 to 6,122,919/ha. Spider-budworm densities/ha covaried significantly (P less than or equal to 0.001) each year (r = 0.84, 1985; r = 0.71, 1986). None of the measured forest-stand parameters (basal area, tree species percentage) were reliable predictors of spider populations/ha.

AN - 15483772; 2214978 AB - The U.S. Department of Agriculture developed a sophisticated physical process model to simulate the soil-climate-plant-management processes in agricultural production and to estimate the impact of soil erosion on resource productivity and fertilizer requirements for the 1985 Resources Conservation Act appraisal. Estimates from this model, the erosion productivity impact calculator (EPIC), show that if cropping patterns and the mix of management, tillage, and conservation practices inventoried in the 1982 National Resources Inventory are continued for 100 years, sheet and rill erosion and wind erosion will exceed the erosion tolerance (T) on 127 million acres and 64 million acres, respectively. This rate of soil loss will reduce productivity in the 100th year by an estimated 2.3 percent--the equivalent to taking 7.4 million acres of cropland out of production.

AN - 15475636; 2207169 AB - Seed production of broadleaved birdsfoot trefoil, Lotus corniculatus L., is critical in southern latitudes to ensure the long-term persistence of stands. Reproductive success of umbels produced early through late season was compared in a field test of 30 F sub(1) genotypes grown on a Mexico silt loam (fine, montmorillonitic, mesic Udollic Ochraqualf) near Columbia, MO in 1984 and 1985. The F sub(1) genotypes represented the progenies of three crosses among parental genotypes of PI 302921, "Norcen", and "MO-20". All genotypes with 10 umbels, each with five flowers, were tagged at weekly intervals between 23 May and 5 July in 1984 and 1985, then harvested at pod maturity. Data were collected on number of pods produced per 10 umbels, number of viable seed per pod, mass of 100 seed, and number of days from tagging to pod maturity. Umbels produced at the early tagging dates produced more pods (P < 0.01), more seed per pod (P < 0.01), and had a greater 100-seed mass (P < 0.01) than umbels produced at later dates. The responses noted appeared to be temperature related. JF - Crop Science AU - Beuselinck, PR AU - McGraw, R L AD - USDA-ARS, Univ.

AN - 15468695; 2198320 AB - Data on offspring production by the alfalfa leafcutting bee, Megachile rotundata (F.), from three site-years were used to examine predictions of parental investment and sex ratio theory. In northern Utah, spring-emergent adults produce two types of offspring: those that develop directly to the adult stage and emerge in midsummer, and those that develop to the prepupal stage and enter diapause until the following year. For species with this kind of life cycle, it has been hypothesized that spring parents should bias their investment in summer emergent progeny towards females if spring males survive to participate in the summer mating. Results from all site-years support the theory. The sex ratio of summer-emergent progeny is always biased towards females, that of diapausing progeny is usually biased towards males, and there is always a significant difference between the two; and there is no difference in the sex ratio of diapausing offspring, whether produced by the spring or summer generations.

AN - 15466394; 2198509 AB - A survey of published and unpublished information was used to compile a list of insect parasitoids recorded emerging from Nezara viridula (L.) in the field worldwide. Fifty-seven species among two families of Diptera and five families of Hymenoptera are recorded; 41 are egg parasitoids. No hyperparasitoids are known. Most species are not closely associated with N. viridula , although some are well adapted and the status of others is unclear. Six species of Nearctic and Neotropical Tachinidae are well adapted to adult N. viridula and could become established in new areas; they also attack large nymphs. There are no effective parasitoids specific to nymphs. The scelionid Trissolcus basalis (Wollaston), probably of Old World origin, is the most widespread egg parasitoid and now occurs with N. viridula in the New World, coastal Africa, southern Europe, Pakistan, Australia, New Zealand, and some Pacific islands.

One sandstone block was placed in a greenhouse at Logan, Utah, where two emerging females established nests within glass tubes inserted into observation boxes and one female excavated a nest in soil beneath the sandstone block from which she emerged. Observations of nesting biology in glass tube nests showed for the first time that polyester cell linings are composed of a mixture of salivary and Dufour's gland materials. Salivary secretion is first brushed onto nest walls with the glossa; Dufour's gland liquid is deposited on top of the salivary layer and brushed into a thin cover layer with the bifid glossa.

Smokybrown cockroaches, Periplaneta fuliginosa (Serville), and Eurycotis floridana (Walker) accounted for at least 67% of cumulative recaptures at each site. Populations were strongly concentrated in palms, trees with treeholes, woodpiles, and (to a lesser extent) various mulches; salient differences were observed for each species, indicating a partitioning of resources. Recapture rates were high, averaging > 62% over all three sites for females of both species; rates were significantly lower for males (P 40%. Mean distances traveled were generally less than 2 m.

Love, and intermediate wheatgrass, Thinopyrum intermedium (Host) Barkw. & D.R. Dewey, was studied in the greenhouse. At peak production, control plants of Great Basin wildrye had more than twice as much green leaf area per tiller than bug-infested ones, and intermediate wheatgrass controls had three times as much as the bug-infested plants. Total leaf area of control plants also exceeded that of bug-infested plants. Watered plants of both species recovered very little after bugs were removed. Drought conditions augmented the reduction in green leaf area on previously bug-infested plants of Great Basin wildrye but not on previously infested intermediate wheatgrass plants.

AN - 15420635; 2164773 AB - The Asian cockroach, Blattella asahinai Mizukubo, a close relative of the German cockroach, B. germanica (L.), has been discovered in over 900 km super(2) from Tampa to Lakeland, Fla., and is prevalent in citrus groves, wooded areas, lawns and homes. Differentiation of the two species is best accomplished by the diagnostic behavior of the Asian cockroach--it is crepuscular (sunset) and nocturnal, readily flies, is attracted at sunset to light-colored or brightly lit surfaces, and lives outdoors in large numbers. Analyses of microhabitat composition of 86 trap sites indicate that the principal habitat of the Asian cockroach is leaf litter in shaded areas. Here, the densities of nymphs and females bearing oothecae were highest. All other adults were more diffusely distributed. Asian cockroaches may be difficult to control because of the mobility of the species and the common occurrence of feral reservoirs.

AN - 15403667; 2138039 AB - Nearly one-quarter of all lands in the United States are managed by the Bureau of Land Management (BLM) and the Forest Service. As a results of laws passed in 1976, the agencies are now developing management plans for this land. The public has many opportunities to provide information and comment as the plans are being developed. Nevertheless, each agency provides an administrative "last chance" to influence informally the way the lands will be managed. One can "protest" a BLM plan between issuance of the proposed plan/Final EIS and the Record of Decision or "appeal" a Forest Service Plan Record of Decision. A key difference between the two processes is that the BLM protest is made prior to the final decision while the Forest Service appeal is of a decision already made.

AN - 15398158; 2146142 AB - Passage of plant cells through a tissue culture culture cycle can induce somaclonal variation (SCV). A potential benefit of SCV is the creation of useful genetic variability, such as disease resistance, without hybridization. Application of SCV technology, coupled with in vitro bioassays for early detection of disease resistance, can benefit tree breeding by reducing the time required for tree improvement.

Bacterial surface properties may influence root colonization ability. Two colony types of the above strains were selected in vitro and tested for ability to colonize seminal roots of wheat in natural soil with or without Ggt. In soil with no Ggt, the frequencies of root colonization were 78% and 48% for 2-79 rough and smooth colony types, respectively, and 60% and 40% for R4a-80 mucoid and nonmucoid types, respectively. Similar trends were observed in experiments using soil amended with Ggt.

Biocontrol of postharvest decay of apples, caused by Botrytis cinerea , has also been documented. In this study, performance of 8 isolates of D. hansenii , obtained from the American Type Culture Collection, was assessed in comparison to the biocontrol activity of US-7, isolated from citrus fruit at AFRS. Pathogens and isolated of D. hansenii were applied to wounded fruit and lesion development was monitored over a 12 day period. Water/pathogen inoculations served as controls. In apples, challenged with Botrytis , US-7 reduced lesion size by 63% compared to controls. Performance of other isolats ranged from a 12-37% reduction.

All four pairwise fusions involving two Met super(-) Leu super(-) and two His super(-) Asn super(-) parents resulted in progeny that grew on minimal medium. Nonparental fusion progeny were recovered at a frequency of 1 x 10 super(-3). Stable recombinants were isolated only after several successive, single conidial isolations on selective media. Fifteen stable His super(-) Asn super(+) and three stable His super(+) Asn super(+) fusion products were isolated.

Strain 30-84 produces phenazine-1-carboxylate and 2-hydroxy-phenazine-1-carboxylate. Previous work with P. fluorescens 2-79 showed that phenazine-1-carboxylate is involved in suppression of take-all. Genetic studies were undertaken to determine if phenazines are also important in take-all suppression by 30-84. Tn5 mutants defective in phenazine production were noninhibitory to Ggt in vitro and were less suppressive of take-all in greenhouse tests. Complementation of mutants by a 30-84 DNa library fully restored phenazine production and fungal inhibition.

It produces both a yellow-green fluorescent siderophore and the antibiotic phenazine-1-carboxylate. Both compounds have been implicated as mechanisms of biological control. To determine the relative importance of each compound in take-all suppression, a set of 2-79 mutants deficient in production of the fluorescent siderophore, the phenazine, or both factors was constructed by recombinant DNA techniques. In all cases the phenazine was the predominant factor contributing to biological control by 2-79 and the fluorescent siderophore made only a small contribution.

BURP is the model name and is not an acronym. Tests of model performance showed BURP is capable of producing accurate simulations of monthly flow for mountainous, snow-dominated watersheds with shallow (< 4 ft) soils when calibrated with 2 to 4 years of streamflow data. A regression of observed versus simulated monthly flows with data from all watersheds combined showed that BURP accounted for 85 percent of the variability in observed flows, which ranged from 0.01 to 20.8 inches, but underpredicted high flow months, with a slope of 1.15 that is significantly different from 1.0 (p = 0.05).

Thirty-five colony-forming units (CFU) of a composite culture of C. jejuni colonized the ceca of one-half of the newly hatched chicks challenged by oral gavage. A challenge dose of 3500 CFU/chick consistently colonized the ceca of all chicks challenged. Challenge doses of approximately 10 super(5) CFU of C. jejuni) per chick resulted in consistent cecal colonization, regardless of whether the birds were challenged 1, 2, or 3 days posthatch. Birds treated with five different CE cultures were colonized at a rate of 81 of 84 chicks; control chicks were similarly consistently colonized (45 of 46 chicks).

AN - 15385927; 2139872 AB - Pollen foraging activity of honeybees (Apis mellifera L.) in a Costa Rican cacao (Theobroma cacao L.) plantation was studied for 6 days during a period of intense flowering (late September). The purpose was to determine the potential of honeybees as pollinators of cacao. Honeybee colonies, with an unknown complement of African (A. mellifera scutellata ) genes, were placed in two distinct habitats: near the centre of the plantation, and at the border between the cacao and surrounding forest. The relative frequency of pollen collection from different pollen sources, was determined daily. Eleven major pollen types were gathered, among which Moraceae, Zea mays , other Gramineae, and Palmae, predominated. No cacao pollen was found in the pollen loads of returning foragers and no honeybees were seen visiting cacao flowers within the vicinity of colonies.

AN - 15317290; 2086985 AB - Nematodes and bacteria are two important interacting members of the soil biota. Of the several possible ecological interactions that occur between nematodes and bacteria, only two, amensalism and parasitism, are considered in depth here. Amensalism, bacterial antibiosis towards nematodes, happens in soil largely as the result of the stepwise bacterial degradation of plant and animal residues. The second interaction, parasitism, emphasizes the bacterium, Pasteuria penetrans , and its interaction with the root-knot nematodes, major crop pests. The ability of P. penetrans to prevent reproduction and eventually kill these root-knot nematodes offers the real possibility of biological control for these major plant pests.

AN - 15290835; 2051292 AB - Host specificity of the flower head weevil Eustenopus hirtus (Waltl) was investigated in Italy and supported its potential and safety as a biological control agent for yellow starthistle, Centaurea solstitialis L., in the United States. Adults damaged yellow starthistle by feeding on young buds and larvae consumed developing seeds. In the laboratory, adults fed and damage capitula of several test plants but females oviposited only on C. solstitialis and two congeneric species. Females experienced little or no oocyte development when confined to plants other than Centaurea .

AN - 15287831; 2049259 AB - Medicago sativa was seeded into an established sward of Bothriochloa caucasica . Two frequencies of sward defoliation were compared to a nondefoliated control. Although 84 to 92% of the root mass at 0-20 cm belonged to B. caucasica during the spring and summer samplings, defoliation generally reduced the root mass of B. caucasica . Defoliation apparently reduced the competitive effects of B. caucasica on M. sativa , as taproot and lateral root mass of M. sativa was much higher in defoliated than in control plots by the end of the growing season. Predawn xylem potential of M. sativa was 0.4 to 0.8 MPa more negative in control than in defoliated plots from mid-summer to fall. Thus, the authors suggest that the transpirational demand of undefoliated B. caucasica reduced soil moisture available to M. sativa , thereby reducing its growth and survival during late summer and fall, compared to defoliated treatments.

AN - 15272962; 2033640 AB - The bioassay has been one of the most widely used tests to demonstrate allelopathic activity. Often, claims that a particular plant species inhibits the growth of another are based entirely on the seed germination response to solvent extracts of the suspected allelopathic plant. The veracity of the bioassay for evaluating naturally occurring compounds for phytotoxicity depends upon the physiological and biochemical response capacity for the bioassay organism and the mechanism(s) of action of the allelochemicals. The possibility that more than one allelochemical, acting in concert at very low concentrations, may be responsible for an observed allelopathic effect makes it imperative that bioassays be extremely sensitive to chemical growth perturbation agents.

Over 80% of the activity extracted from the callus tissue bound to a concanavalin A-Sepharose 4B column. The bound activity was eluted from the column by the addition of methylmannose to the eluting buffer. On the basis of this result, it appears that most of the cyokinin oxidase activity present in Great Northern callus cultures exists in the form of a glycoprotein.

AN - 15209756; 1977271 AB - Analytical (50 mu g) reversed-phase high-performance liquid chromatography (RP-HPLC) of fractions from soy protein purifications has been scaled up to injections in the preparative (1-200 mg) range to obtain sufficient quantities of glycinin subunits for sodium dodecyl sulfate-polyacrylamide gel electrophoresis characterization. The authors describe here the glycinin separations obtained by using analytical, semi-preparative, and preparative columns with an analytical gradient HPLC system. Parameters such as injection volume, flow-rate, and detector sensitivity are noted. The results suggest that analytical RP-HPLC separations of proteins can be conveniently scaled up in most HPLC systems. JF - Journal of Chromatography A AU - Peterson, R E AU - Wolf, W J AD - North.

AN - 15202419; 1974759 AB - Thirty calves (3 to 4 months old) were exposed conjuctivally to a pathogenic strain of Brucella abortus . Experimental infection of cattle is commonly achieved via topical administration of brucellae to conjunctivae. Because numerous brucellosis studies use the conjunctival route and exposure, it is important to determine the route for mechanism by which organisms enter the host. The purpose of the study reported here was to evaluate localization of brucellae at selected times after conjunctival exposure of calves to a pathogenic strain of B. abortus .

AN - 15185696; 1956330 AB - Road building, clearcutting 25 percent of the watershed, and slash disposal by broadcast burning or by natural decomposition caused changes in water quality of two small streams in the Bull Run Watershed in Oregon, which supplies water to the Portland, Oregon, metropolitan area. Concentrations of suspended sediment increased slightly, primarily owing to construction of a permanent logging road that crossed streams. Changes in nutrient cycling occurred due to logging and slash disposal in both watersheds where cutting was done. NO sub(3)-N concentrations, which increased most where logging residue was left to decompose naturally, increased more than sixfold and commonly exceeded 100 mu g/l during the October-June high-flow season for seven years after logging.

Sarg and J. osteosperma (Torr.) Little) woodlands of the southwestern United States. Maximum-size/density relations, leaf area and growth of pure and mixed-species woodlands are compared. Structure of pure and mixed-species woodlands appeared to be restricted by maximum-size/density relations. Maximum Stand Density Index (SDI) for mixed-species woodlands was 30% greater than for pure woodlands. Ceiling leaf areas were 3.6 for mixed-species, 3.5 for pure pinyon and 1.0 for pure juniper woodlands. Ceiling leaf area varied with species mix and soil type.

Larvae were found in clusters of 25 to 5544 individuals on the tips of vegetation and averaged 20.8 to 26.2 cm above ground. Larvae did not exhibit any obvious preference among 25 plant species for ascension. Differences in the height that larvae clumped depended on the vegetation available since > 90% of the larvae were found at the maximum plant height; larvae were not found on larger trees and shrubs.

AN - 15180610; 1951461 AB - Four types of spruce budworm pheromone lures were field-tested in sparse spruce budworm populations in Maine. BioLures with constant pheromone emission rates of less than 1.0, ca. 1.0-1.5, and ca. 15.0 micrograms of pheromone per day were compared to polyvinyl chloride (PVC) lures with rapidly decreasing pheromone emission rates. Mean trap catch was roughly proportional to lure emission rates. All lures continued to catch moths over the entire flight period but moth catches with the three lowest emission-rate lures were judged to be too low. BioLures with the highest emission rate (15.0 micrograms of pheromone per day) showed the lowest variability in trap catch and the fewest zero trap catches.

AN - 15173767; 1952141 AB - Weekly samples of cotton leaf, bract, fiber, and soil were taken during the 25-week growing season of 1985 at the Southern Regional Research Center, New Orleans, Louisiana. Total and gram-negative bacterial populations were determined. Both types of populations remained relatively stable until senescence and, later, frost resulted in higher counts for each. Pseudomonas sp. were the predominant types present on the plant parts, with Enterobacter agglomerans the second most common. Senescence affected bacterial populations on the cotton plants, with some bacterial types increasing and others decreasing after senescence. Statistical analysis partitioned by sample type showed strong correlations between certain microbial and environmental variables with endotoxin levels. Gram-negative bacterial count was the most accurate predictor of endotoxin levels. The multiple regression of endotoxin on environmental parameters suggests that week of growing season, ambient air temperature, or dew point also may be adequate predictors of endotoxin in hot, humid environments.

AN - 15172246; 1951834 AB - The authors attempted to determine whether weaning is required for induction of diarrhea in pigs with postweaning enterotoxigenic Escherichia coli infection. Three-week-old newly weaned pigs and their suckling littermates were inoculated with the K88 super(+) enterotoxigenic E. coli) strain M1823B. The incidences of diarrhea, weight gain rates, and the numbers of strain M1823B shed in feces of susceptible weaned and suckling pigs were not significantly different. Diarrhea scores of susceptible weaned pigs were significantly (P < 0.02) higher than those of susceptible suckling pigs on the second day after inoculation. In this experimental model, it was concluded that weaning is not required for induction of diarrhea, but may modestly increase its severity.

AN - 15171569; 1952197 AB - Two-dimensional polyacrylamide gel electrophoresis was used to analyze and compare the effects of short term treatments (24 h) of salt stress, water deficit (desiccation), and osmotic stress (polyethylene glycol and mannitol) on protein synthesis in roots of barley seedlings (Hordeum vulgare L.cv. CM 72). These comparisons were made to determine if the polypeptides of M sub(r) 26,000 and 27,000 and pI of 6.3 and 6.5 that were observed previously to increase significantly with salt stress also increased with water deficit and osmotic stress. The polypeptide patterns for control- and stress-treated plants were qualitatively similar, but the net synthesis of a number of polypeptides was quantitatively altered by each of the stress treatments.

AN - 15170676; 1951827 AB - A review of data from over 50 freshwater and about 50 salt-water sites revealed that freshwater and salt-water forested wetlands exhibit parallel responses to hydrologic factors. Greater ecosystem complexity and productivity are associated with higher hydrologic energy and more fertile conditions (riverine > fringe greater than or equal to basin > dwarf = scrub). However, structural complexity is greater in freshwater forested wetlands than in salt-water forested wetlands. Net primary productivity, litter fall, and export of organic matter are higher in slat-water forested wetlands. These differences raise questions about the efficiency with which nutrients are used in forested wetlands. Available data suggest that nutrient-use efficiency by litter fall and litter turnover are higher in tidal salt-water wetlands than in freshwater wetlands.

AN - 15167976; 1949151 AB - The effects of T-2-toxin on protein synthesis, respiratory chain activity of the mitochondria, cell lysis and toxin-cell binding were compared in the toxin-sensitive bovine kidney cell line (MDBK) and in the toxin-resistant Chinese hamster ovary cell line (CHO). Protein synthesis and mitochondrial activity were 10-fold less sensitive in CHO cells as compared to MDBK (50% inhibition = 10-15 ng/ml vs. 1-1.5 ng/ml, respectively). The results indicate that T-2 toxin mediates a number of effects on the cell at the level of the membrane, protein synthesis and probably mitochondrial activity toward 3-(-4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide reduction.

Cells in deep crevices which formed in muscle during water immersion were not visible by SEM until the tissue was shredded, suggesting entrapment of bacteria.

Stands ranged from 40 to 900 yr old, and most if not all, originated after fire. The dynamics of CWD were modeled for three histories, each beginning with an initial fire in an old-growth stand but differing in number and severity of subsequent fires. All three models exhibited low values of CWD between 80 and 200 yr. The results of the study indicate that a steady-state condition in CWD may not be reached for > 1,000 yr, and that the nature and timing of disturbance play a key role in the dynamics of CWD in the region.

AN - 15145599; 1930026 AB - A plant growth model has been developed as a component of a general rangeland production and utilization model (SPUR). The carbon and nitrogen content of standing green, live roots, propagules, standing dead, litter, dead roots, soil organic matter and soil inorganic nitrogen are simulated. The model can simultaneously simulate up to seven plant species or species groups on a total of nine heterogeneous range sites. It incorporates processes which are common to C sub(3) and C sub(4) plants but does not consider plants with Crassulacean Acid metabolism. When coupled with the other components of the SPUR model, the plant component allows testing of grazing management, environmental variation, and fertilizer application.

AN - 15140361; 1930325 AB - A 24 Kd peptide was produced upon inducing callus formation from excised seedling tissues and immature embryos in vitro of Sorghum bicolor (L.) Moench. Callus formation was always preceded by production of this callus-associated peptide (CAP1), as detected by two-dimensional polyacrylamide gel electrophoresis (2-D PAGE). CAP1 and a second callus-associated peptide, CAP2, are more abundant in callus tissue which has lost the ability to regenerate organ primordia in comparison to organogenic callus. Anti-serum developed to CAP1 was found to be reactive with both CAP1 and CAP2. Concanavalin A (Con A) bound both CAP1 and CAP2, indicating the presence of glycosyl residues associated with these peptides.

AN - 15138378; 1922116 AB - The ability of Bacillus circulans peptidoglutaminase to deamidate soy proteins was investigated. Peptidoglutaminase readily hydrolyzed the gamma -amide of glutamine residues in soy peptides, but its activity toward soy proteins was low (0.4-1.3% deamidation). Molecular size and conformation of soy protein may be critical to enzymatic deamidation. Gel adsorption was used to partially purify the enzyme. Gel eluates exhibited higher activity than the cell extract toward soy peptides and all soy proteins but 11S globulin. The specific activity of the gel eluate toward 7S globulin and a water extract of soy flakes was doubled over the original cell extract.

AN - 15130293; 1915461 AB - American foulbrood disease is dreaded by most beekeepers as many states destroy hives found with this disease. The disease can be transmitted by feeding honey contaminated with spores of Bacillus larvae . Honey samples were examined using this improved method and the authors found detectable levels of B. larvae in 33 of 58 samples from various sources. Bacillus larvae is not known to cause any adverse reactions in humans. The previous minimum detectable level of spores in honey was approximately 6,000 spores per milliliter. Using this method, it is now possible to detect 80 spores per milliliter of honey. JF - American Bee Journal AU - Shimanuki, H AU - Knox, DA AD - Benefic.

AN - 15125717; 1910234 AB - Laboratory studies on the effects of simulated solar radiation on Entomophaga grylli conidial viability showed definite interactions between the duration and intensity of exposure to the light source. When either variable was increased, the viability of E. grylli conidia was reduced. An exponential decay model was developed based on combining these two factors into a single predictive variable, exposure to cummulative solar radiation in Langleys. The model predicted over 95% mortality in the most open habitats after exposure to ca. 50 Langleys. As expected, conidia exposed in lower canopy areas and in canopies with more dense foliage survived significantly longer (ca. 95% mortality after exposure to 700 Langleys).

AN - 15122670; 1907406 AB - A 31-kilodalton (kDa) protein extracted from Brucella abortus was previously cloned into Escherichia coli and expressed at high levels. The E. coli -derived protein can be purified by a simple 2-step procedure entailing detergent extraction followed by ion-exchange chromatography. Using specific antiserum raised against the E. coli -derived protein, 34 strains of Brucella , representing all 6 recognized species, were examined for expression of the 31-kDa protein by Western blotting. This protein was detectable in all, but one Brucella species (B. ovis ), including all 8 biovars of B. abortus tested. This degree of conservation supports further study of the 31-kDa protein for potential exploitation as a vaccine or diagnostic component.

AN - 15118385; 1905981 AB - Pruning is a silvicultural practice that has generated much discussion but little action toward Douglas-fir management during the last four decades. This paper presents the results of a lumber and veneer product recovery study conducted on pruned and unpruned coastal Douglas-fir (Pseudotsuga menziesii ) butt logs. The study included 146 sawlogs (97 pruned, 49 unpruned) and 151 veneer logs (100 pruned, 51 unpruned). Logs were selected from a 75-year-old stand that was pruned about 35 years ago. The key results of the study are: 1) pruned logs recovered the same volume of products as unpruned logs but recovered more high-grade lumber or high-grade veneer; and 2) recovery of high-grade lumber of high-grade veneer increased as the diameter of the knotty, unpruned core decreased.

AN - 15118246; 1908530 AB - Soil populations of Macrophomina phaseolina , cause of charcoal rot of soybean and various rots and blights of a large number of cultivated plants, might be managed by crop rotation if the density of infective microsclerotia in soil could be reduced below damaging levels. The soybean cultivar Forrest was grown in monoculture and in a 2-, 3-, or 4-yr rotation with corn, cotton, and grain sorghum from 1980 to 1984 in soil infested with the soybean cyst nematode, Heterodera glycines .

The effect of these very small trees on means, variances, and variance ratios was evaluated for height and diameter in a 16-year-old plantation by systematically deleting from analyses the shortest individuals in wind-pollination (W) and diallel (D) progenies of six parent trees. The progenies were growing together in a common field test. The D population served as a control (no inbreds). JF - Forest Science AU - Sorensen, F C AU - White, T L AD - USDA For.

Female Swiss ICR mice were given a single dose of T-2 toxin (4 mg/kg of body weight) by gastric gavage. On the seventh day after toxin administration, the mice were infected by intraperitoneal inoculation with L. monocytogenes, S. typhimurium , or M. bovis . The effect of the toxin on the course of infection was monitored by observing mortality or by enumeration of bacteria in the spleen or lungs of infected mice. The toxin increased resistance to infection with L. monocytogenes initiated by intraperitoneal inoculation, but reduced resistance to M. bovis infection initiated by intraperitoneal inoculation.

Soybean and cottonseed meals contain about 60% and 50% of total phytate as water-soluble forms, respectively. The water-insoluble portion of phytate was further hydrolyzed and removed by application of microbial phytase. Treatment at higher temperature (50 degree C), pH 4-5.5, and heating the substrate (1 h at 121 degree C) prior to enzyme treatment facilitated the hydrolysis of phytate by the microbial phytase. The heat treatment also reduced the level of total extractable phytate from these substrates. JF - Journal of Agricultural and Food Chemistry AU - Han, Y W AU - Wilfred, A G AD - Southern Reg. Res.

AN - 15110323; 1911609 AB - Long-term records of precipitation and streamwater chemistry are rare; such records from forested watersheds relatively free of acidic deposition are even rarer. Precipitation and streamwater chemistry have been measured on two undisturbed forested watersheds at the H.J. Andrews Experimental Forest located on the western slopes of the Cascade Mountains of Oregon. Data from one watershed spans the period 1973-1985, the other 1969-1985. The mean annual pH of precipitation was 5.5 with a range of 4.7 to 6.0. HCO super(-) sub(3) was the dominant anion; Ca super(2+) and Na super(+) were the dominant cations. The mean annual pH of streamwater was 7.3, and was dominated by HCO super(-) sub(3) and Ca super(2+). THese data contrast sharply with data from other calibrated watersheds in the north Cascade Mountains of Washington and British Columbia, and with data from New Hampshire and North Carolina where pH of precipitation averages 4.14 and 4.43, respectively, with SO super(2) sub(4) super(-) the dominant anion.

AN - 15102161; 1895662 AB - Wingless insects and very small insects generally depend on air currents to carry them to new sites, but they tend to settle in areas with low windspeeds. It is often more advantageous for a flying insect to remain within its boundary layer where windspeeds are lower than the insect's flight speed. Flying insects tend to accumulate in areas of reduced windspeed where they have greater control of flight; however, distribution patterns can be modified by directed movements in response to olfactory and visual stimuli. Windbreaks can concentrate insects in particular areas. Insects accumulate leeward of windbreaks as compared with unsheltered sites. The pattern of distribution may be affected by wind-speed, angle of incidence of the wind, permeability of the windbreak, turbulence, source of insects (windbreak, local fields, upwind sites), insect behavior, insect species and vegetative composition.

AN - 15100932; 1894943 AB - A method for scheduling southern pine beetle detection flights was developed and implemented as a computer program entitled OVERFLIGHT. The program determines the seasonal arrangement of flights that minimizes spot age, and therefore, forest damage, at the time of detection. The only data input to the program are the percentage of annual spots initiated in each month. These data were obtained from state pest control officers and the methodology applied to two regions of the South. The results indicate the best seasonal positioning of flights. Also incremental flights showed decreasing marginal gains in reducing spot age with little improvement beyond five flights per year.

Plant resistance has been suggested as a potential control. In this study, dent corn genotypes varying in resistance to second-generation European corn borer (ECB), Ostrinia nubilalis (Huebner), damage were evaluated at two locations for insect tunneling and aflatoxin formation in kernels of preharvest ears. To insure uniform exposure, plants were inoculated with Aspergillus flavus (Link) spores applied to the ear node and silk and were infested with ECB eggs applied to either the ear node or ear tip. Corn germplasm classified as resistant to second-generation ECB damage sustained significantly less ear damage than susceptible genotypes.

AN - 15098978; 1894867 AB - Population growth was compared in 21 colonies of honey bees, Apis mellifera L., during the period of maximal population growth in Louisiana. Each colony began with 1.25 kg of bees, no brood, and 40 liters of hive space (measured empty). Colonies differed in comb size (13 by 19, 13 by 43, 20 by 43, or 26 by 43 cm), but each hive had the same comb surface area (1.1 m super(2)). Bees were put into hives on 12 March, queens were released 15 March, and hives were expanded to 1.4 m super(2) of comb surface area and 48 liters on 10 April. Colonies with the largest combs produced more brood and had more adult workers on 13 May than colonies with the two smallest combs. At the end of the experiment, mean adult populations were 19,300, 22,900, 23,600, and 28,400 in colonies with the smallest to largest combs, respectively.

Three-day exposures to these volatiles significantly inhibited germination of all assay seeds, and the degree of inhibition was dependent upon seed species, exposure time, and concentration. The activities of these compounds appear to be additive and dependent on relative volatility and hydrophilicity. JF - Journal of Chemical Ecology AU - Bradow, J M AU - Connick, WJ Jr AD - Agric. Res.

AN - 15096691; 1885515 AB - Saccharomyces cerevisiae and Saccharomyces rosei were tested for use in mixed culture fermentation of cucumber juice with Lactobacillus plantarum . Extent of sugar utilization and the ratio of products formed (lactic acid:ethanol) were influenced by time of inoculation and cell numbers of each microorganism. Sugar fermentation was complete within 6 days at 28 degree C when similar numbers of bacteria and yeasts were added simultaneously, or when yeasts were added before the bacteria. Sugar remained when only L. plantarum was added, or when yeasts were added in low numbers. Glycerol was produced when yeasts were present, the concentration being directly related to NaCl concentration. Results suggest advantageous uses of yeasts to complete fermentation and to modify acidity.

AN - 15096096; 1884095 AB - The requirements for regenerating northern red oak can be hypothesized from an understanding of the species' ecological life-history characteristics along with a knowledge of past and present disturbance patterns. Frequent fires and heavy cutting favored oak because of its sprouting ability, while fires reduced common competitors. Its regeneration requires an edge environment; one that is more mesic than exposed, open sites, but less competitive than the deep shade of a forest understory. Intense competition can be expected on the mesic sites suitable for northern red oak, and this competition must be controlled when regenerating this species.

AN - 15095740; 1889997 AB - Four-week old chickens were administered 0.5, 5.0, or 10.0 mg of cyclopiazonic acid (CPA)/kg of body weight by crop intubation and were killed 3, 24, 48, or 96 h later. Breast and thigh muscle was removed from the carcasses, and the content of CPA in the meat was measured by a high-performance liquid chromatographic procedure. CPA was found in the meat from birds in each dose group, and the amount found was dependent on both dose given and the elapsed time after dosing. The maximum muscle content of CPA occurred 3 h after administration and ranged from 50 ppb in birds given 0.5 mg/kg to over 5000 ppb in some birds given 10.0 mg/kg.

AN - 15093015; 1889695 AB - While diurnal cycles in nitrogen fixation rates are sometimes assumed to result from diurnal variation in photosynthetically active radiation, contradicting evidence exists that indicate soil temperature is the primary environmental influence. These studies assessed the significance of temperature on soybean nitrogen fixation under field conditions. Two groups of intact field-grown soybean plants, one at ambient and the other exposed to a 10 degree C diurnal variation in soil temperature, were nondestructively assayed for acetylene reduction rates.

AN - 15092828; 1890157 AB - Effects of fire on vesicular-arbuscular mycorrhizal fungi were tested using microcosms constructed from soil, litter, and duff collected beneath canopies of pinyon pine, Utah juniper, and in the open space (interspace). Burning was conducted over wet and dry soils. Soil temperatures were monitored continuously throughout the microcosms during burning. Plants grown in soils burned when dry had a lower VAM colonization than soils burned when wet. Juniper soils demonstrated the greatest reduction, over 95%, compared to their respective controls. Plants grown in interspace soils burned when wet were least affected. There was a positive correlation between the decrease in VAM colonization and the soil temperature as a result of the fire. Temperature effects, and associated reductions in VAM, were related to amount of litter burned in each microcosm and the moisture content of the soils.

AN - 15083606; 1883550 AB - Marginal farmlands seeded to grasses in the Southern Great Plains usually have been depleted in N by cropping, cultivation, and erosion. This study measured soil N accumulation over 20 to 22 years in N fertilized weeping lovegrass (Eragrostis curvula ) or Old World bluestem (Bothriochloa caucasica ) pastures seeded into old fields as compared to adjacent unfertilized old field pastures dominated by sand dropseed (Sporobolus cryptandrus ). Significantly more (P < 0.05) total N was found in the surface 5 cm of soil from the fertilized pastures. The N accumulation rate in the N fertilized pastures appears to be considerably slower than the N depletion rate under past farming practices.

AN - 15083598; 1875978 AB - Inhibition or stimulation of porphyrin synthesis was found to influence th activity of the p-nitrodiphenyl ether herbicide acifluorfen (2-chloro-4-(trifluoromethyl)phenoxy-2-nitrobenzoate) in cucumber (Cucumis sativus L.) cotyledon disks exposed to light after being loaded with acifluorfen in darkness. Gabaculine (3-amino-2,3,dihydrobenzoic acid) and 4,6-dioxoheptanoic acid, inhibitors of porphyrin synthesis, greatly (> 90%) reduced the activity of acifluorfen. Similar results were obtained with primary leaves of redroot pigweed (Amaranthus retroflexus L.) and velveltleaf (Abutilon theophrasti Medic.). Gabaculine dramatically (> 85%) reduced the activities of other diphenyl ether herbicides (fluorodifen, oxyfluorfen, and nitrofen) while having no effect on the activity of the nondiphenyl ether herbicides paraquat and rose bengal. Gabaculine also decreased the activity of acifluorfen in tentoxin-treated tissues which normally accumulate very little chlorophyll although they do have the capacity for porphyrin synthesis.

AN - 15081443; 1880361 AB - Earthworm feeding and casting activities are difficult to monitor because of problems associated with assessing subsurface activity in the field. Thus it is difficult to predict the effect of a change in cropping pattern on earthworm activity with its attendant effects on soil structure and nutrient cycling. Therefore, feeding and casting activities of Lumbricus terrestris L. and L. rubellus Hoff. were monitored in laboratory cultures with each species provided with alfalfa, bromegrass, corn, red clover or no-food diets. Both species produced predominately surface casts under experimental conditions. Food consumption values of L. rubellus ranged from 5 to 52 mg g super(-1) live worm day super(-1) and were several times higher than those for L. terrestris (2-13 mg g super(-1) live worm day super(-1)) for all food sources except bromegrass, which both species rejected as food.

Bacteroids of root nodules of stem-nodulating species are relatively complex structurally and contain extensive invaginations of the membranes, clusters of DNA organized into nucleoids, and several electron opaque inclusions. The bacteroids in all of the stem-nodulating Aeschynomene species examined are generally enclosed singly in peribacteroid membranes and are oval-shaped. The data indicate that bacteroid ultrastructure might serve as structural clue as to potential stem-nodulating species and may relate to an underlying metabolic difference between stem-nodulating and non-stem-nodulating spp. JF - Cytologia AU - Stegink, S J AU - Vaughn, K C AD - Southern Reg.

AN - 15075859; 1878591 AB - The conservation of old-growth forests has become a major conservation issue. The maintenance of wildlife diversity is an important value associated with old-growth conservation. Lately, policies related to managing old-growth wildlife have emphasized just one management strategy, habitat preservation. The ecology of the red-cockaded woodpecker (Picoides borealis ), a species dependent on old-growth pine forests in the South, suggests that additional management strategies are appropriate for some old-growth species.

AN - 15075545; 1878656 AB - Changes in the structure and function of Douglas-fir forests as they develop from young stands to old growth are examined. Old-growth Douglas-fir/western hemlock forests are a long-lived phase of a potentially very long successional sequence. After disturbance, some ecosystem attributes, such as leaf area and water quality, recover relatively quickly, while others, such as live and dead woody structures, which are important for wildlife, return to predisturbance maxima and toward a relative steady state only after four or five centuries. The gradual and variable nature of succession and stand development make the task of precisely defining old growth difficult. The authors propose an index of "old-growthness" or structural diversity that may be a useful tool in maintaining and managing successional diversity in forest landscapes.

AN - 15073155; 1876609 AB - Spatial distribution of soil and water properties and the correlations between them and crop yield were determined for a natural rainfall environment. Hydraulic conductivity, soil texture, water retention, and soil-water flux were variables used to investigate their relationship to crop yield using multiple regression techniques. Variations in crop yields on a watershed with a 3 to 4 percent slope and moderately erosive soils were related to soil-water characteristics and soil properties along slope and with depth. Climatic conditions to sustain crop growth and yield ranged from inadequate soil water in 1983 to adequate soil water in 1984. Crop yield was predicted with models using both available and measured soil-water content. Available water content provided a better model for the prediction of water yield and does not require field measurements of actual soil-water content.

AN - 15065772; 1866622 AB - In 1983, while monitoring a Bald Eagle nest in Arizona, the authors observed mate replacement and full adoption, which provided an opportunity to verity one aspect of adoption theory under natural circumstances. Given that habitat familiarization contributes to experience of pairs, and that perch use is one mechanism of that familiarization process, the authors hypothesized that the replacement adult should perch more selectively as the season progressed, i.e., exhibit less movement between fewer perches. In this paper, they present results of the perch analysis, along with documentation of the mate replacement and full adoption.

The metabolite, trivially named cinereain, was a ruby red crystalline product with the molecular formula C sub(18)H sub(21)N sub(3)O sub(3) and melting point 201 similar to 203 degree C. The structure was unequivocally established by single crystal X-ray diffraction; UV, IR, NMR ( super(1)H and super(13C) and mass spectrometry supported the crystallographic data. Cinereain significantly inhibited the growth of etiolated wheat coleoptiles at 10) super(-)3a)nd 10 super(-4) M in bioassays. No effects were noted on treated intact greenhouse-grown bean and tobacco plants, but there was mild necrosis and chlorosis in corn.

Product inhibition studies showed competitive inhibition between acetyl-coenzyme A and coenzyme A and between NADH and NAD. Uncompetitive inhibition was found between pyruvate and NADH or acetyl-coenzyme A, while noncompetitive inhibition was found for NAD or coenzyme A.

AN - 15061499; 1864543 AB - Forage cell walls were fermented with ruminal inocula to release phenolic-carbohydrate complexes. Fluid portions of the fermentations were centrifuged to collect a small-particle fraction. Solutions were separated on a Sephadex G50 molecular sieve column into five fractions. Original solutions and the six fractions of each forage solution were used to replace 50 or 100% of the buffer in a ruminal fermentation of cellulose or hemicellulose. Alkaline-extractable phenolic composition differed among forages for the solutions and among the fractions. All solutions depressed fermentation of both carbohydrates, and volatile fatty acid proportions were different from controls.

Groups of poults were exposed intramuscularly to various concentrations of organisms of each strain. Both strains were virulent. The strain isolated from a turkey was highly virulent. The high degree of virulence of a B capsular group strain isolated from a turkey indicates a disease-producing potential for members of this uncommon serogroup of P. multocida .

AN - 15060430; 1848150 AB - The ability of modern biotechnology to produce new or modified proteins has outpaced current understanding of the relationship between protein structure and protein function. Resolution-enhanced infrared spectroscopy and Raman spectroscopy are excellent non-destructive techniques for investigating the secondary structure of proteins under a wide variety of conditions. The techniques yield rapid, reliable estimates of the proportion of helical structure, beta -strands, and turns of proteins in solution, as gels, or as solids. These methodologies can also detect subtle variations in protein conformation that frequently occur upon change of the biomolecular environment.

However, most M. demolitor females reared from H. zea larvae fed an artificial diet were not responsive at emergence to the same volatile semiochemicals. A preflight contact with frass from H. zea fed cowpea was needed to stimulate a response of sustained flight in a wind tunnel. Chilling the parasitoid pupae rendered most of the emerging females unresponsive to volatile semiochemicals.

Treatment in two pastures consisted of sagebrush removal and interseeding alfalfa and cicer milk-vetch. Two pastures were not treated. Treated pastures were grazed half as long untreated pastures but with twice the number of steers. Forage yield decreased in all pastures because of below-average precipitation and grasshopper density increases. Melanoplus sanguinipes (F.), increased more in treated than untreated pastures; six additional abundant species, did not increase more in treated pastures. Thus, treatments did not markedly affect total grasshopper population trends but did influence species composition and provided additional food plants for some species.

Larvae hatch shortly thereafter and there are three larval instars. Larval feeding causes the needles to at first droop, discolor, and eventually drop, reducing the quality of Christmas trees and occasionally killing shoots. Larvae overwinter on the ground in cocoons, and pupate in spring.

AN - 15052904; 1855234 AB - Rate of development of the immigrant azalea lace bug, Stephanitis pyrioides (Scott), reared on hybrid evergreen azalea, was measured at three constant temperatures. Egg development across temperatures was nonlinear and ranged from a mean of 11.6 d at 31.7 degree C to 23 d at 20.6 degree C. Stadial development rate between instars for both sexes was similar at each temperature. Development of instars across temperature was nonlinear. Single males and females lived longer at 20.6 degree C than single and paired cohorts at 26.1 and 31.7 degree C. Single males lived as long as 246 d and females 253 d at 20.6 degree C. Fecundity and average oviposition rate varied nonlinearly with temperature. Presence of the male was found to affect oviposition rate. Postoviposition longevity for females is reported.

AN - 15050483; 1845540 AB - The physical basis of the linkage between magnitude and timing of channel flow hydrographs and drainage network morphometry is reviewed. Small Hortonian and structurally Hortonian networks are analysed using numerical runoff simulation. For Hortonian networks the variability of the geometry of individual channels and subcatchments within each Strahler order has little effect upon the overall character of the hydrograph in channels of higher order. If the network is structurally Hortonian, the analysis of the simultaneous formation, travel, and concentration of the hydrographs in all channels of the network can be simplified to a sequence of one representative hydrograph per channel order. Three major runoff processes control the flow hydrograph characteristics: the overland flow process which determines the water supply to the drainage network; the channel flow process which translates the hydrograph in space and time; and the drainage network process which concentrates and magnifies the flow at the junctions of the drainage network. Functional relations for the hydrograph peak, timing, and flow velocity are presented. JF - HYDROL. PROC. AU - Garbrecht, J AU - Shen, H W AD - USDA, Agric. Res. Serv., Ft.

These two isolates were very similar to, but distinguishable from, a third isolate from Italy (CLRV-WRS) that induced ringspots on leaves of English walnut. In pathogenicity tests, all three walnut isolates (CLRV-W8, -Wsp, and -WRS) infected Hartley English walnut cultivar and caused blackline symptoms at the English walnut/Juglans hindsii graft union. Uninoculated control trees and trees inoculated with CLRV cherry and golden elderberry strains remained healthy and virus-free.

AN - 15040982; 1846579 AB - Basic wind erosion processes are discussed under the major headings of soil particle dynamics, particle flow rates, and principles and general strategies of control. Particle dynamics are described in terms of suspension, saltation, surface creep, abrasion, sorting and threshold conditions. Soil particle flow rates are divided between the all-erodible-particle case and the more common but more complex case of mixtures of erodible particles and non-erodible elements. Specific principles of wind erosion control are identified. A wind erosion equation, which estimates potential erosion from a particular field, and the conditions necessary to reduce potential erosion to tolerable amounts are discussed.

AN - 15040932; 1846661 AB - Wind erosion is a problem where soil movement exceeds the tolerable limit for the soil or where soil movement begins to damage the crops being grown. On soils with a wind erosion potential and where adequate residues are not available to control wind erosion, it is necessary to divide that field into a series of isolated fields. By using a combination of practices, properly designed wind erosion control systems can be tailored to fit specific crops, irrigation methods and farming practices of individual landowners.

AN - 15038418; 1838905 AB - Apples were pressure infiltrated at harvest with solutions of CaCl sub(2) and stored at 0 C. After 6 mo, fruit were removed from storage and cell walls were extracted and analyzed for Ca content. Polygalacturonase was purified from the decayed area of nontreated apples that had been inoculated with Penicillium expansum). Cell wall Ca content was positively correlated with the present Ca used in the infiltration solutions. Extracted walls with varying Ca content were then used as substrate for P. expansum polygalacturonase to test the effect of wall Ca on in vitro enzyme activity. Approximately 60% less product was formed when high Ca cell walls were used as substrate compared with low Ca cell walls. Since Ca in known to stabilize the cell wall, decay in apples with high levels of Ca may be decreased because maceration by polygalacturonase is reduced.

In vitro, 12 mg/L of sodium hypochlorite (NaOCl) and 62 mg/L of benzalkonium chloride (BC) eliminated all viable bacteria. Time of exposure to the bactericides had a significant effect on survival of E. amylovora . Addition of Ortho X-77 surfactant to the bactericides reduced the efficacy of the NaOCl solution, but had no apparent effect on BC. On artificially infested apple fruits, NaOCl at 450 and 500 mg/L plus 0.25% of surfactant greatly reduced, but did not totally eliminate, viable bacteria.

AN - 15036186; 1846643 AB - Wind erosion is controlled by reducing the wind erosion forces on erodible soil particles and/or by creating aggregates or soil surfaces more resistant to wind erosion forces. This can be accomplished by reducing field width, maintaining vegetation residues on the soil surface, utilizing stable soil aggregates or clods, roughing of the land surface and leveling of the land. While individual conservation practices can be successful in controlling erosion, a combination of practices should always be considered when a wind erosion control system is being planned. Droughts will cause a shortage of residue in the stubble mulch program, erosive winds will not always blow in the prevailing direction when barriers are used, and aggregation, soil clods and ridging for erosion control are all temporary control measures and serve best as supplemental practices.

The detection of injury was based on the use of differential media: plating on tryptose phosphate broth + 2% agar and 1% sodium pyruvate (TPBA + P) and on tryptose phosphate broth + 2% agar and 5% NaCl (TPBA + S). Only non-injured Listeria formed colonies on TPBA + S whereas both heat-injured and non-injured cells formed colonies on TPBA + P. The bacterial count on TPBA + P minus that on TPBA + S represents the extent of heat injury.

Prevention strategies encourage producers to adopt quality control measures in their production management. These activities have been effective in reducing the occurrence of violative residues and the potential for adverse health effects. Overall, the number of domestic monitoring samples containing violative residues is low-about 1% of samples. Violative residues are found less frequently in poultry than in livestock. More occur in swine than in other species; the least number occur in fed cattle and broilers. Testing results over 10 yr show that most drugs and pesticides used to enhance agricultural productivity are not causing a residue problem.

The post-microsomal fractions of both SRRC 163 and SRRC 2043 were able to convert sterigmatocystin (ST) into O-methylsterigmatocystin (OMST); whereas the microsomal preparation of only SRRC 163 was able to convert OMST into aflatoxin B sub(1) (AFB sub(1)). S-Adenosylmethionine (SAM) was the primary substrate for the ST to OMST (methyltransferase) enzymatic conversion; ( super(3)H)OMST of specific activity 0.93 Ci/mmol was obtained in a reaction containing the ( super(3)H)SAM substrate (specific activity 1 Ci/mmol). After the terminal enzymatic conversion of OMST into AFB sub(1), none of the radiolabel of the methyl group from OMST was found in AFB sub(1).

AN - 15029115; 1832588 AB - Nine months after inoculation of loblolly pine (Pinus taeda ) seedlings with basidiospores of Cronartium quercuum f.sp. fusiforme , most symptomatic tissues had necrotic cells in cortex. When infection caused depressed areas, necrosis included xylem and phloem cells. Whereas tissues in galls longer than 10 mm were heavily and extensively colonized by the rust, tissues from galls shorter than 10 mm had rust mycelium only in small, isolated areas in the cortex, phloem, or xylem. Seedlings with no stem symptoms or with purple stem spots but no swelling when outplanted at 9 mo were symptomless 24 mo after inoculation. Seedlings with galls shorter than 10 mm at 9 mo were symptomless 24 mo after inoculation. Seedlings with galls shorter than 10 mm at 9 mo usually were free from symptoms (63-67%) after 24 mo. Seedlings with galls 10-25 mm long at 9 mo had the highest frequency of galls and aecia at 24 mo, whereas those with galls 10-25 mm long with depressed areas and those with galls longer than 25 mm had the highest mortality rates.

AN - 15025562; 1831204 AB - Atmospheric fluidized-bed combustion represents an economical technology for the burning of high S fossil fuel. The combustion residue is a dry, alkaline material resulting from the burning of coal (or other fuel source) and limestone. Although the residue has been assessed as a limestone substitute, the current study examines the potential for disposing of relatively large quantities. Fluidized bed material (FBM) was applied at two rates to the surface area within the rows of an established apple (Malus domestica Borkh.) orchard containing four tree types. The rates were either 9.2 kg/m super(2), 36 kg/m super(2), or untreated control. The tree types used were "Spuree Rome" on M9, "Redchief Delicious" on M9 or M9/MM106, and "Sturdeespur Delicious" on M9. Cumulative yields were enhanced on three of four tree types over a period of 6 yr. A 15% reduction in yield was noted for Redchief Delicious on M9/MM106 stocks at the high FBM rate.

Tubers of the S. tuberosum fusion parent, and two potato cultivars, Katahdin and Russet Burbank, were susceptible to bacterial soft rot, whereas tubers of the somatic hybrids were resistant. Furthermore, some of the sexual progeny from crosses between the somatic hybrids and Katahdin had the same high level of resistances as the somatic hybrids. Thus, the resistance incorporated from S. brevidens by somatic fusion was sexually transferred.

AN - 15024847; 1828135 AB - Ascospores of Epichloe typhina germinated and produced phialides and conidia within a 24 h period, but produced no mycelium. This type of microcycle conidiation was referred to as iterative germination. All attempts at producing mycelium from ascospores failed; ascospores developed conidia under all cultural conditions tried in the study. Conidia produced during the process were viable, and morphologically similar to those produced in culture by mycelium, and to those produced by the fungus on its host meadow grass, Sphenopholis obtusata . This is the first report of microcycle conidiation by ascospores. Since the ascospores required no thermal or precultural induction period, it was concluded that in contrast to this phenomenon by conidia of other fungi, iterative germination to form conidia by ascospores of E. typhina is obligatory.

Variables included the presence or absence of certain habitat types near the survey field, the size of the survey field, the distance between rows, and the average head size and plant height. Other factors that had significant associations in at least 1 year were row spacing; presence or absence of adjacent plowed fields, pastures, and trees; and weed density in the survey field. The ecological relevance of these factors to blackbirds is discussed. JF - FISH WILDL. SERV. TECH. REP. AU - Otis, D L AU - Kilburn, C M AD - USDA, Anim. and Plant Health Inspect.

A decision support system was developed to aid in selecting inputs to a basin scale soil and water resources model. The system prompts users for input values and formats them in the model input file. The system also accesses large data bases, interfaces with expert systems, gives explanations, suggests default values, and provides graphics. Technology transfer will be enhanced by decreasing the time and money spent during model use and increasing user confidence in the model.

AN - 15019318; 1830377 AB - The output from a pesticide screening model indicated that chemicals with low Henry's Law constants (K sub(H)) will tend to accumulate at the soil surface when water is evaporating, resulting in an increased volatilization with time. Volatilization losses and surface distributions of two pesticides with widely differing K sub(H) were measured to test the predictions of the screening model, particularly with respect to the importance of K sub(H) in controlling relative volatilization and vapor behavior. Volatilization of prometon (2,4-bis(isopropylamino)-6-methoxy-s-triazine), a Category III compound with low K sub(H), increased with time with water evaporating and prometon accumulated at the soil surface.

AN - 15018629; 1830588 AB - This approach has the potential to be simpler and more efficient than some previously developed models. Another important attribute of queuing theory is its ability to model almost unlimited detail. Many simulation languages based on queueing theory have been developed and tested and are available. Applications of the languages include manufacturing operations, transportation systems, computer systems, financial planning, and health care systems. A model was developed, using a simulation language, to predict runoff hydrographs from storms occurring on small homogeneous watersheds. With continued development, queueing theory could provide an efficient, detailed approach to simulating many natural processes.

A network optimization model was used to simulate water flow, storage, consumptive use, and loss within the entire Colorado River Basin with and without the flow increases, according to various scenarios incorporating both current and future consumptive use levels as well as existing and potential institutional constraints. Results indicate that very little of the flow increases would be consumptively used at current use levels, or even at future use levels, if water allocation institutions remain unchanged.

AN - 15016052; 1830823 AB - Citrus B viroid (CBV), differing from the citrus exocortis viroid in host range, symptom expression, and reaction with viroid-specific molecular probes, has been identified in many commercial citrus trees in Sicily. Citrus B viroid replicates in cucumber (Cucumis sativus L. "Suyo") plants and produces symptoms similar to those induced in cucumber by the hop stunt viroid (HSV). Molecular hybridization with HSV-specific RNA probes has demonstrated that the nucleotide sequence of CBV is closely homologous to that of HSV, indicating that the viroid is a strain of HSV. Citrus B viroid, alone or in conjunction with other viroids, may be responsible for inducing the citrus cachexia (xyloporosis) disease.

AN - 15015258; 1828241 AB - Phanerochaete chrysosporium ligninase (+ H sub(2)O sub(2)) oxidized the lignin substructure-related compound acetosyringone to a phenoxy radical which was identified by ESR spectroscopy. Cellobiose:quinone oxidoreductase (CBQase) + cellobiose was without effect on the radical. Ligninase polymerized guaiacol and increased the molecular size of a synthetic lignin. These polymerizations were unaffected by the CBQase system. The authors conclude that ligninase catalyzes phenol polymerization via phenoxy radicals, which CBQase does not affect. The CBQase system did not produce H sub(2)O sub(2), and its physiological role remains obscure. Glucose oxidase + glucose did produce H sub(2)O sub(2), but it did not reduce the phenoxy radical of acetosyringone. Because intact cultures of P. chrysosporium) depolymerize lignins, it is likely phenol polymerization by ligninase is prevented or reversed in vivo. JF - Biochimie.

Gregarine protozoans and Beauveria bassiana have been reported to cause mortality in cultures of Diabrotica virgifera virgifera and D. undecimpunctata howardi . B. bassiana occasionally causes significant mortality of adult D. barberi and D. v. virgifera in Illinois and Nebraska. During studies on the population ecology of D. barberi in central New York, an entomophthoralean pathogen was found to cause moderate levels of mortality of field-collected adult beetles in the laboratory.

AN - 15012257; 1817891 AB - Carboxyarabinitol-1-phosphate (CA1P) is a naturally occurring inhibitor of ribulose-1,5-bisphosphate carboxylase/oxygenase (rubisco) which appears in the leaves of some plants during darkness and occupies the ribulose-1,5-bisphosphate binding site. The involvement of the rubisco activase protein in the regulation of rubisco activity by CA1P was investigated. The data suggest that rubisco activase interacts with rubisco to alter the RuBP binding site, thereby increasing the dissociation rate of bound CA1P from the enzyme.

AN - 15010421; 1823853 AB - To protect cattle against bovine genital campylobacteriosis, the interaction of vaccine dose, strains(s) of Campylobacter fetus and type of adjuvant was studied in the pregnant guinea pig model. Five strains of C. fetus were used in the preparation of 20 monovalent vaccines containing various doses of bacteria (0.1 mg to 20 mg, dry weight) in Freund incomplete adjuvant, Freund complete adjuvant, or aluminum hydroxide gel adjuvant. Vaccinal protection against homologous or heterologous challenge exposure with viable C. fetus strains was measured in terms of infection, abortion, and serum antibody titers. Major emphasis was placed on vaccines containing highly virulent C. fetus subsp. venerealis (1289 and 17761) that possess most the heat-labile K antigens that have been identified. Vaccines incorporating strain 1289 provided greater protection against abortion than did strain 17761 vaccines.

AN - 15009502; 1826903 AB - Data from 25 experiments on seedling of 43 tree species and hybrids show that ozone (O sub(3)) can reduce growth and photosynthesis at concentrations common in many areas of the USA. Seedlings have been primarily employed for such studies for logistic reasons, and will likely provide the greatest breadth of information for some to come. However, a number of impediments limit application of seedling response studies to assessment of impact on regional timber production. Large trees differ from seedlings in a number of ways, including C allocation and canopy structure, and methods must be developed to account for these differences if information from seedling studies is to prove useful to forest impact assessment. Understanding how competition mediates individual tree responses will require investigation of whether systematic differences of microclimate leaf morphology that exist across canopies affects foliage sensitivity to O sub(3), and whether the maximum growth rates of genotypes are correlated with susceptibility to O sub(3).

AN - 15007096; 1822144 AB - Several oomycetous fungi have shown potential as microbial control agents for mosquito larvae. Unfortunately the most promising among them, Lagenidium giganteum Couch, cannot infect larvae in water with greater than 1 ppt (part per thousand) of NaCl. This precludes its use in the salt marsh breeding sites of many important pest species. The experiments indicate that NaCl at concentrations up to about 5 ppt enhances mycelial growth. Higher salt concentrations are progressively inhibitory, with growth failing to occur at 20 ppt. This is similar to the growth rate pattern of Lagenidium giganteum on saline agar. In practical terms, salinity would not affect parasitic development of the fungus within its host, and it would probably not be an impediment to potential saprophytic growth in the breeding sites of most salt marsh mosquitoes.

On day 28, pigs were euthanatized and necropsied, and tissues were removed for histologic examination. Neither liver weights nor bone ash values were altered, although liver lipid values were increased. Serum aspartate transaminase, gamma -glutamyl transferase, and alkaline phosphatase activities were increased, whereas creatine kinase activity was decreased. Aflatoxin diets resulted in decreases in serum concentrations of urea nitrogen, phosphorus, cholesterol, albumin, and total protein. Histologic alterations in liver included interlobular fibrosis, periportal lipidosis, bile duct hyperplasia, and periportal lymphocytic infiltration. Lymphocytes in the thymus were depleted, and numbers of granulocytic cells in the bone marrow were reduced. The frequency and severity of lesions increased with increased doses of AF.

Two methods of inoculation of Culex quinquefasciatus were examined and compared as to rate of kill, route of invasions, histopathology and pathogenesis, and presence or absence of toxin-related mortality. Toxin is apparently released during digestion; partially digested conidia are evident in electron micrographs of midguts of moribund larvae. Some conidia were shown to be at the beginning stages of germination in the midguts of moribund larvae but no invasion of tissue was apparent. In both treatments, conidia must be viable in order to cause mortality in mosquito larvae. JF - Journal of Invertebrate Pathology AU - Lacey, C M AU - Lacey, LA AU - Roberts AD - USDA, Agric. Res.

AN - 14992773; 1806745 AB - In previous mark-recapture studies, laboratory-reared male gypsy moths, Lymantria dispar (L.), tended to arrive at pheromone sources 1-3 h later feral males. In this study, laboratory-reared male pupae were exposed to five different temperature regimes, and the resulting adults were tested in an actograph at 25 degree C. Males that had been held at lower temperatures as pupae became active earlier than males that had been held in warmer treatments. Temperature-mediated programming provides a potential means of synchronizing activity rhythms of sterile males with those of wild males in target populations.

AN - 14992291; 1803045 AB - Indian ricegrass (Oryzopsis hymenoides (Roem. and Schult.) Ricker) is a valuable forage species in the western United States; however, low fresh-seed germination has limited its use in range-land revegetation. Seed damage and germination effects were evaluated on 2 seedlots of "Nezpar" Indian ricegrass exposed to 3 mechanical treatments. The air-gun scarifier and the Quaker Oats dehuller improved germination whereas the Forsberg dehuller decreased germination. Disruption of the seed coat before storage appears to be a practical method of reducing storage time required for improved germination of freshly harvested seed.

The technique was tested in a postseason experiment in which 6,000 larvae were released in a stand. Frass yield was measured by individually caging several larvae in the field on cut host foliage. The most reliable and efficient method of measuring frass drop was the deployment of several large funnel-shaped frass traps near the forest floor.

AN - 14989980; 1805530 AB - The dispersal of mass released Muscidifurax zaraptor Kogan & Legner, a solitary pupal parasitoid of house flies and stable flies, was monitored in two fly breeding habitats. Under a raised feedbunk, parasitism ranged from 32.5 to 63.5% when monitored by a linear arrangement of sentinel house fly pupae. Dispersal pattern were not apparent; average parasitoid emergence from sentinel pupae on each side of the release point were not significantly different. Parasitoid releases in open-piled manure generally produced lower parasitism levels than under the feedbunk.

AN - 14989455; 1805514 AB - Increased range of virulence of stripe rust (Puccinia striiformis West.) on wheat (Triticum aestivum L.) in the northwestern USA has required assemblage of a broad genetic base of resistance. This study genetically differentiated among 14 sources of stripe rust resistance represented by near-isogenic lines developed in stripe rust-susceptible "Lemhi 53." Plant reactions of the lines were evaluated in F sub(1), F sub(2), and BC sub(1) populations from resistant by susceptible crosses and in F sub(1) and F sub(2) populations from resistant by resistant crosses. Greenhouse-grown seedlings and field-grown adult plants were tested for their reactions to the fungus.

AN - 14989436; 1805511 AB - Teat disinfection after milking and nonlactating cow treatment are effective procedures to control contagious mastitis pathogens. However, these procedures do not effectively control infection caused by environmental mastitis pathogens. The intramammary device (IMD) was developed for the control of intramammary infection by environmental mastitis pathogens. The purpose of the study were to determine the pattern of the SCC response to the abraded IMD during the milking and intermilking periods and to determine whether the abraded IMD would provide protection against infection after challenge exposure with Streptococcus uberis . After challenge exposure, 2 of 5 of the quarters with abraded IMD, 4 of 5 of the quarters with smooth IMD, and 8 of 9 control quarters became infected. Results indicated that abraded IMD increased SCC in stripping milk to concentrations that provided 60% protection against challenge exposure with S. uberis .

AN - 14985203; 1805149 AB - Field trials were conducted for three fungicides (Captan, Botran, and Carbendazim) to determine their influence on chalkbrood of the alfalfa leafcutting bee, Megachile rotundata (F.) in paper, wood, and plastic nesting units. Captan reduced disease incidence significantly in bee nests in both wood and plastic; Carbendazim had no effect; and Botran repelled adults. Bees preferred to nest in plastic units, and percentage of cells infected with chalkbrood was higher in plastic. Numbers of cells per nest and disease incidence were related; as nest size increased, percentage of chalkbrood increased in both wood and plastic nest units. Percentage of live larvae was related to nest size in wood units, but not in plastic units. When bees were given a choice, paper nesting units were unattractive.

In field tests, impact of the mite on buffalo fly survival was measured in natural field pats enclosed in screen cages. Buffalo fly mortality was highest when eggs of this species were placed on top of dung pats rather than beneath them. Maximum mortality obtained was 83%; there was no increase in mortality at predator/prey ratios above one mite per two fly eggs. The mite caused highest mortality when exposed to hatching eggs and young larvae of buffalo fly, but it showed a strong preference for eggs of other dipteran species that have softer egg chorions.

AN - 14980208; 1802567 AB - Bacillus thuringiensis was encapsulated within a starch matrix and assayed for biological activity against larvae of the European corn borer, Ostrinia nubilalis . When larvae ingested encapsulated B. thuringiensis , they digested the starch matrix and released into their guts B. thuringiensis crystals and spores, which initiated infection. Nearly 100% mortality occurred at all dosages and concentrations tested whenever the starch granules were hydrated and high relative humidity conditions (> 80%) were maintained during the 24-h exposure period of the assay.

AN - 14974405; 1798319 AB - The potential of Bacillus subtilis for postharvest control of peach brown rot caused by Monilinia fructicola was assessed in pilot tests on simulated commercial packing lines at Byron, GA, and Clemson, SC, and in a commercial packinghouse in Musella, GA. Because disease pressure was low due to drought conditions (1986), inoculum was introduced either in the dump tank water or as a spray onto the fruit after treatment on the line. In packing line tests, the number of colony-forming units of the bacterium added to each fruit was between 2 x 10 super(7) and 7 x 10 super(7) for B-3 from flask cultures and approximately 2 x 10 super(9) for B-3 from the fermentor culture. In a test at Byron, B-3, cultured in flasks and applied fresh or after being stored (as paste or powder), was equal to benomyl (1-2 ppm residue in fruit) for brown rot control.

AN - 14966133; 1786592 AB - Carpenterworm, Prionoxystus robiniae (Peck), survival ranged from 0-86% among 15 southern, bottomland hardwood host species. Carpenterworm survival, rate of development, and fecundity were generally greatest in the oaks (Quercus spp.), cottonwood (Populus deltoides Bartr. ex Marsh.), and boxelder (Acer negundo L.). Favored host species usually had smaller, more uniform cambial cavities, whereas less preferred species had larger, more irregularly shaped cavities with long, narrow lateral extensions. Gallery lengths and diameters varied little among host species but were significantly shortest for 1-yr males and longest for 2-yr females.

AN - 14965670; 1793246 AB - Ecological impacts on camp and picnic sites were examined in three National Park Service units along the Delaware and New rivers, in the eastern United States. All sites experienced pronounced impact to trees, groundcover vegetation, and soils. The nature and magnitude of impacts in these riparian forests were quite similar to those reported in wilderness in the mountainous western states and northern Minnesota. This suggests that the effectiveness of basic strategies for managing impact should not differ greatly between regions.

The average developmental period of two nematode populations from Lewiston, Utah, and Rupert, Idaho, from J2 to J3, J4, adult, and the next generation J2 at soil temperatures of 18-28 degree C were 100, 140, 225, and 399 degree-days (base 8 C), respectively. There was a positive relationship (P < 0.05) between nematode Pi, nematode generations, and sugarbeet yields. The greatest sugarbeet growth inhibition (87%) occurred when sugarbeets were exposed to a Pi of 12 eggs/cm super(3) soil for five generations (1,995 degree-days), compared with a 47% inhibition when plants were exposed to the same Pi for two generations.

No nematode infection occurred at 10 C with any R. reniformis population, and the population from Puerto Rico did not reproduce at 15 C. Nematode survival was not influenced by temperature, since populations from Texas and Louisiana survived for 6 months without a host at -5, -1, 4, and 25 C. Survival of R. reniformis was substantially influenced by soil moisture. Soil moistures greater than 7% ( 15 bars) favored nematode survival below freezing but adversely affected nematodes in soils stored at 25 C.

Predawn xylem water potential of low sagebrush declined rapidly, reaching -3.5 to -5.5 MPa by late summer. Big sagebrush values dropped to -2.0 to -3.0 MPa during summer drought. The drop in sagebrush xylem water potential was related to the decline in soil water potential (r = 0.68 and 0.82). The change in pinyon predawn xylem water potential was moderate, declining to values of -1.5 to -2.5 MPa. Pinyon seedlings appear to have greater drought avoidance than sagebrush nurse plants.

AN - 14956235; 1774035 AB - Waters from 20 wells in a primarily agricultural Pennsylvania watershed were analyzed for the most heavily and extensively applied pesticides as determined by farm survey. Those analyzed were atrazine, metolachlor, cyanazine, alachlor, terbufos, chlorpyrifos, fonofos, and carbofuran. No metolachlor, alachlor, terbufos, chlorpyrifos, fonofos, or carbofuran were detected. However, atrazine concentrations ranging from 13 to 1110 ng/L were found in 14 of the 20 wells. These findings suggest widespread atrazine contamination of the groundwaters, but at extremely low concentrations. Cyanazine was found above trace concentrations in one well. Although there was only one record of application, simazine was found in seven wells within the range of 10 to 170 ng/L. The degree and spatial distribution of atrazine contamination depended mostly on the frequency and distribution of corn production.

AN - 14955280; 1778977 AB - A greenhouse study was conducted to evaluate the effect of fly ash and agricultural lime on ameliorating the low pH of acidic coal mine spoils. Topsoil depths of 0, 10, and 20 cm placed over the spoil were also evaluated. Two crops of barley (Hordeum vulgare L.) were grown to evaluate effects of the amendments and topsoil on aboveground plant biomass, root biomass and distribution, and element content of the vegetation. All levels of lime and fly ash significantly increased the spoil pH, aboveground plant biomass, and significantly increased the spoil pH, aboveground plant biomass, and root biomass. Topsoil placement over the spoil also generally increased plant biomass. When the spoil was amended with either fly ash or lime root growth occurred throughout the material. Fly ash and lime did not cause elemental toxicities to the plants, except for B. Although visual B toxicity symptoms and elevated levels of plant B were evident, no reduction in plant biomass occurred.

AN - 14954180; 1784016 AB - Using a model system of cotton and the causative agent of bacterial blight, Xanthomonas campestris pv. malvacearum (Smith) Dye (XCM), microbial transmission by feeding of the cotton fleahopper, Pseudatomoscelis seriatus (Reuter) (CFH), was studied. In controlled feeding tests, artificially infected CFH infected 51% of the plans they attacked. Of these infected plants, 81% exhibited symptoms of the disease, while 19% did not exhibit symptoms, but contained the bacterium. After feeding to acquire XCM, salivary glands and alimentary tracts were dissected and assayed for the presence of XCM. The bacterium was reisolated from 60% of the salivary gland pairs examined, and 95% of the alimentary tracts that were analyzed.

The combined population reductions caused by threshing and drying were calculated to be 89, 89, and 92% for hybrids F-4507, D-1214, and P-3030, respectively. Correlations between storage populations (STOR-6 and STOR-12) versus earlier populations (UNDRIED and DRIED) were highly significant (P < 0.0001) with r super(2) values from 0.48 to 0.72. This suggest that sampling of seed after threshing may help in predicting future populations densities in storage.

AN - 14953853; 1775742 AB - This study examined the contribution of agriculture to the nutrient (N and P) concentrations in the Wye River, an estuarine tributary of the Chesapeake Bay. The river drains a watershed that is devoted mainly to farming and is devoid of any sources of municipal and industrial wastes. Water samples were analyzed for NO sub(3)-N + NO sub(2)-N and molybdate-reactive P (MRP). The concentrations of these forms of nutrient were then examined in relation to sampling site, sample salinity, and time of year. Freshwater entering the river (brackish) from the watershed contained consistently high concentrations of NO sub(3)-N and low concentrations of PO sub(4)-P. Once these nutrients entered the estuarine part of the river, however, the concentrations of NO sub(3)N decreased to low levels within a short distance (500-700 m) from the point of riverine discharge, through both dilution with brackish water and apparent microbial action.

AN - 14953635; 1779086 AB - Kojic acid is a secondary fungal metabolite that is commonly produced by many species of Aspergillus and Penicillium . These fungi also produce mycotoxins that occur as components of distinctive secondary metabolite profiles, which can serve as reliable chemotaxonomic characters at the species level. The mycotoxin aflatoxin B sub(1), produced by Aspergillus flavus) Link: Fr., is highly toxic (LD sub(50) of 7.2 mg/kg to rats). However, kojic acid, which is also produced by A. flavus , is relatively nontoxic and has not been implicated in any naturally occurring toxicoses to man or animals. This research investigates the toxicity of aflatoxin B sub(1) and kojic acid, alone and in combination, to Spodoptera frugiperda) and Heliothis zea .

In central Oregon, key features of the insect's seasonal history were related to heat accumulation (degree-days (DD) above 5.5 degree C) and phenological characteristics of one of its hosts, ponderosa pine, Pinus ponderosa Douglas ex Laws, and eight other associated shrubs and forbs. These relationships permit the status of the shoot borer's seasonal history, such as the egg-laying period, to be established indirectly from local temperature records or by observations of some obvious phenological characteristics of its host and associated plants.

AN - 14949602; 1768977 AB - Growth of ponderosa pines with visible symptoms of ozone injury was compared with that of asymptomatic trees in the southern Sierra Nevada, California. Time series analysis indicated that there was no significant reduction in annual radial increment of symptomatic trees during recent years compared to past growth of asymptomatic trees. First order autocorrelation and climatic variables accounted for a large proportion of the variance in growth index, and winter precipitation was positively correlated with growth for all size and age classes. Although ozone concentrations are high enough to cause chlorosis and premature needle senescence in ponderosa pine, there has been no significant change in growth associated with ozone injury.

AN - 14941293; 1773560 AB - Recent work has identified ethanol toxicity as a major factor preventing continuous production of ethanol at the concentrations obtainable in batch culture. In this paper the authors investigate the use of a continuous two-stage bioreactor design to circumvent toxic effects of ethanol. Biomass is produced via continuous culture in the first stage reactor in which ethanol concentrations are either absent or maintained at low levels. The freshly grown cells are fed into the second bioreactor in which high ethanol concentrations are produced. The steady influx of fresh cells and continuous removal of spent cells helps minimize the loss of fermentative activity that results from anaerobiosis and exposure to high ethanol concentrations.

AN - 14939625; 1764715 AB - By behaviourally thermoregulating, T. eques maintain their temperature between 30 and 40 degree C for much of the day, and thus optimize its effects. T. eques survives in a desert environment with a short and unpredictable favourable season that a erages 692 degree-days (DD). However, this grasshopper requires 850 DD to develop. By thermoregulating, T. eques increases its developmental rate, enabling it to complete its life cycle before the habitat fails. In this sense T. eques is a 'maxitherm'. For this grasshopper, the antipredation features of black aposematic coloration and unpalatability allow rapid radiative heating, and extended conspicuous exposure.

AN - 14937689; 1764792 AB - Ingestion of tall larkspur (Delphinium barbeyi L. Huth) is a major cause of cattle death on ranges where the plant occurs. The amount and timing of tall larkspur ingestion by grazing cattle was studied from 30 July to 2 September 1986 on high mountain rangeland in central Utah. At the time of major consumption, leaves were relatively low and declining in total alkaloid concentration (TAC) (1.0-0.6%) while pods were approximately 1.0% TAC and increasing when the study ended. Time spent per feeding station (TFS) was influenced by the vegetation area where animals foraged. Cattle ate large quantities of tall larkspur during the study with no deaths, probably due to the low alkaloid levels in the tall larkspur.

AN - 14935868; 1768204 AB - Land managers have recommended burning or mowing big sacaton (Sporobolus wrightii ) grassland in either fall or winter for 100 years. The objective of this study was to determine how seasonal burning and mowing influences big sacaton forage quantity and quality. Plants defoliated in fall produced leaves within 215 to 245 days, those defoliated in summer within 3 days, and those in winter within 20 days. Green and dead forage that accumulated after the burning and mowing in the same seasons were similar, but differences occurred among seasons. Burning or mowing at any season removes green forage available to livestock and reduces the amount of green forage that may accumulate for at least 2 summer growing seasons.

Torr.), poverty threeawn (Aristida divaricata Willd.), tobosa (Hilaria mutica (Buckl.) Benth.), and burrograss (Scleropogon brevifolius Phil.) were used to examine changes in perennial grass basal area and forb densities. Quadrats originally dominated by black grama had large reductions in basal area during droughts, and basal area increased slowly following droughts. Perennial forb densities were low and fluctuated among years in all types. Annual forbs and grasses displayed large fluctuations in densities among years.

During active growth (May and June) when temperatures were not limiting, photosynthesis (PS) was higher for burned (25-27 mu moles super(-2) s super(-1)) relative to unburned plants (20-25 mu moles m super(-2) s super(-1)); but during summer drought, PS declined to < 10 mu moles m super(-2) s super(-1) and treatment rank reversed. The authors concluded that burning big bluestem increased leaf area during the active growth period and stimulated PS, resulting in higher carbon uptake of burned relative to unburned plants.

AN - 14912903; 1744568 AB - The sex ratios were determined for Boophilus microplus (Canestrini), B. annulatus (Say), and hybridized Boophilus ticks reaching the adult stage on cattle. The sex ratios (females to males) of B. microplus and B. annulatus were 1.36:1 and 1.35:1, respectively. In a hybrid of these two species, the ratio was 1.20:1. Thus, proportionately more hybrid males reached adulthood than in either pure strain. The proportion of male hybrids reaching adulthood may have been the result of hybrid vigor. The fact that more females than males reached adulthood in the three types of ticks is probably because these ticks have an XX-XO sex-determining mechanisms.

AN - 14908638; 1738552 AB - Migration of extractives to the wood surface alters the properties of wood as an adherent. Extractives change the wettability and the curing properties of adhesives. A desirable wettability-permeability relationship ship is sometimes affected by extractives, thus reducing the gluebond strength and performance. Past efforts to determine which of the components of extractives affect adhesion are reviewed. The most common deleterious effect of extractives on finishing is discoloration of coatings and paint films. Another adverse effect is that extractives retard the hardening of finishes. Not all the effects are unfavorable, however. Some extractives significantly improve the durability of the surface coating and contribute to paint holding.

Fewer and generally smaller cysts developed on Rosa than on Katahdin. Although cyst size significantly influenced VEC, cyst age (8 or 13 weeks) had no effect. Regardless of size, cysts produced on Rosa contained significantly fewer viable eggs than did cysts produced on Katahdin. The fecundity of progeny from cysts produced on Rosa was significantly reduced compared with that of progeny from cysts produced on Katahdin.

AN - 14902426; 1729420 AB - Potential herbicide loadings to groundwater are determined by soil, chemical, management, and climatic factors. Several simple assessment procedures to rank pesticides according to their potential impact on groundwater are available. Most of these procedures are not specific to any climatic region, cropping practice, or soil. Using a continuous simulation model, GLEAMS (Groundwater Loading Effects of Agricultural Management Systems), to assess potential herbicide leaching allows more condition-specific assessment. Simple relationships for relative comparisons in a specific soil/climatic setting were developed by relating simulated 50-yr mean leaching losses to the herbicide half-life/K sub(OC) ratio. Other criteria of herbicide leaching potential such as 50-yr maxima or other values based on probability distributions could be used.

AN - 14888029; 1730618 AB - The relative abundance of small mammals in 5 forest land cover types on the upper Coastal Plain of north Mississippi was determined. Burrowing mammals accounted for one-half of the total captures; one shrew species that accounted for over one-fourth of the total captures had a strong affinity for well-stocked pine plantations. The opportunity for detention and retention of rainfall was enhanced by burrowing activity. Reductions of stormflow volumes 12 to 15 years after replacing poor quality, upland hardwoods with locally pine were only partially explained by increased interceptions of rainfall; much of the residual reductions are postulated to be due to small mammal burrows.

AN - 14884931; 1726072 AB - Patterns of spread of 85 weed species alien to the northwestern U.S. were simulated using principal coordinate analysis on primarily herbaria-derived data. The primary pattern detected was a west-to-east migration of weeds. The point of introduction for most weeds following this pattern appeared to be near Portland, OR, an important shipping port in the past. An east-to-west migration represented a secondary pattern. The major cattle and wheat-cropping areas of east-central Montana were the apparent introduction points for weeds following this pattern.

Behavioral and chemical evidence for the role of age and social experience. AN - 14884765; 1726516 AB - A combination of behavioral and chemical analyses was used to investigate the nature of nestmate recognition cues and the effects of worker age and social experience on these cues in the ant Camponotus floridanus . Freeze-killed workers from each category elicited more aggressive behavior in the alien colony than in its own. By comparing gas chromatography profiles, a worker from any category can be assigned to its colony of origin. Thus all studied worker categories are colony-specific. Solvent-washed ants did not induce more aggressive behaviors in the alien colony than in their own, but they induced significantly less aggressivity in an alien colony than nontreated dead ants from the same category.

AN - 14881707; 1718092 AB - The progress of alfalfa leaf spot diseases, caused primarily by Leptosphaerulina briosiana , was monitored to compare characteristics of disease development among five cultivars in successive growth cycles within a growing season. The rate of disease progress and the shape of the disease progress curve were generally similar among cultivars but varied among growth cycles. Disease severity often decreased toward the end of an epidemic within a growth cycle. Defoliation and accumulation of debris toward the end of epidemics generally corresponded to decreased levels of visible disease near the time of harvest. A simple theoretical simulator, constructed to examine some of the unique factors that appear to influence disease development in the alfalfa leaf spot pathosystem, indicated that defoliation was not the sole cause of the decreased disease severity at the end of an epidemic.

AN - 14879657; 1718500 AB - Open-pollinated progeny from 156 loblolly pine trees in the USFS-Georgia Forestry Commission orchards were inoculated with Cronartium quercuum f. sp. fusiforme . Nine months after inoculation, the incidence of galls among the 156 families ranged from 2 to 97%. The susceptible control family had significantly more galls than 116 of the 156 other families tested according to the 0.70 disease ratio computation. The 0.70 disease ratio was more conservative than a chi-square test of independence in separating resistant and susceptible families. Responses to infection were compared between resistant and susceptible families to determine the relative frequency of resistant responses. The absence of stem symptoms was the most common resistant response in many resistant families. The third-generation progeny derived from resistant selections 2318, 10-5, and 42R had 50% or more seedlings with this response.

AN - 14870378; 1714937 AB - Winter wheat (Triticum aestivum L.) was either subjected to fall grazing or left ungrazed and was examined the following spring for above and below ground growth, carbohydrate pools, and root length colonized by vesicular-arbuscular mycorrhizae (VAM). Root colonization by VAM occurred in both grazed and ungrazed winter wheat during reproductive growth (late spring). Prior to May, low soil temperatures apparently inhibited VAM colonization. Percent VAM colonization did not differ between treatments during reproductive growth, but root length per unit of soil volume was reduced by grazing, resulting in a greater colonized root length for ungrazed plants. Grazing reduced total carbohydrate pools. Although grazing and VAM colonization were separated in time, a grazing effect on colonization was evident.

AN - 14866200; 1692141 AB - Fluorescent pseudomonads and nonpathogenic isolates of Fusarium oxysporum were effective in inducing suppressiveness to Fusarium wilt of cucumber when added to soil together (pH 6.7) but ineffective when added separately. Suppressiveness by such combination treatments was enhanced in nearly neutral (pH 6.7) to alkaline soils (pH 8.1), in comparison with acid soil (pH 5.5). Strains of fluorescent pseudomonads reduced the germination of chlamydospores of nonpathogenic and pathogenic isolates of F. oxysporum in the rhizospheres of cucumber plants. It is hypothesized that the activity of fluorescent pseudomonads and their siderophore production are enhanced by increased root exudates induced by relatively high population densities of nonpathogenic isolates of F. oxysporum . This, in turn, leads to competition for iron, which is essential for successful germination of the pathogen and penetration of the host.

AN - 14842555; 1691086 AB - Tall fescue (Festuca arundinacea Schreb.), has a reputation for poor animal performance. Discovery of an association between the fungal endophyte (Acremonium coenophialum Morgan-Jones and Gams) and fescue toxicosis made it possible to achieve high levels of animal performance on low-endophyte tall fescue. Steer average daily gain (ADG) has been 30 to over 100% higher on low-endophyte than on high-endophyte tall fescue pasture. For each 10% increase in endophyte level there is 0.1 lb depression in ADG over an entire grazing season. Adverse effects of the endophyte have been demonstrated in hay and seed. It has been shown to reduce milk production, and there are indications that it adversely affects reproduction. Intake is reduced on endophyte infected fall fescue.

AN - 14838516; 1689323 AB - The parasitism of tall fescue (Festuca arundinacea Schreb.) by an endophytic fungus is reviewed relative to the biology of the fungus and the symptomless expression within the grass. A consideration of the taxonomy of the fungus as Acremonium coenophialum is presented and justifications for the affinity of the fungus with the clavicipitacious fungus tribe Balansiae is discussed. The in vitro physiology and growth of the fungus in culture is reviewed and related to fungus specific compounds, as well as compounds specific to the association.

Bed load transport was measured in Bambi creek, a small gravel-bedded stream on Chichago Island, Alaska, for 33 autumn storm flows from 1980 to 1985. The transport of fine sediment was more frequent than coarse sediment, and scouring of coarse material in the reach was triggered only by high flows. Within a given storm season, both antecedent storm history and cumulative flow (above the threshold for bed load transport of 0.25 m3 per second) influenced bed load transport. During the six year period, both riffles scoured along most of the channel width while the middle portion of the pool filled.

In test furrows irrigated with clean water, intake rates at the top end were 50-100 times higher than in downstream sections where fine sediment adsorbed on the wetted perimeter formed a thin seal that decreased erosion by reducing water intake rates and increasing soil water tension forces (as measured with tensiometer sensors). Damage to part of the sediment seal reduced soil water tension, with formation of scour holes and development of head cuts. Irrigation with sediment-free water resulted in substantial erosion at furrow flow rates of 8, 12 and 15 litres per minute on 0.04, 0.012 and 0.007 slopes respectively. These observations suggested that fine sediment should not be removed from irrigation water supplied to silt loam soils.

AN - 78006538; 3128394 AB - Individual reaction requirements were determined for each of two enzyme activities present in Aspergillus parasiticus mycelia which together catalyze conversion of sterigmatocystin (ST) to aflatoxin B1 (AFB1). A postmicrosomal activity (PMA) catalyzed conversion of ST to O-methylsterigmatocystin (OMST) and a microsomal activity (MA) catalyzed conversion of OMST to AFB1. PMA was stimulated two- to three-fold in the presence of S-adenosylmethionine. Addition of NADPH promoted the maximum MA; this activity was not detected when FAD, FMN, NAD, or NADH were utilized individually as cofactors in reaction mixtures. A substantial amount (62%) of MA was lost during isolation of the microsomal fraction, but the activity was completely restored by reconstitution with a heat-treated (100 degrees C) postmicrosomal fraction. The reaction catalyzed by MA was optimum at pH 7.0 and at 17-23 degrees C, whereas the PMA reaction was optimum at pH 8.0-8.5 and at 35-40 degrees C. Apparent Km values of approximately 2.6 X 10(-6) M (for ST) and 6.6 X 10(-7) M (for OMST) were determined for PMA and MA, respectively.

AN - 77931650; 3435144 AB - A new metabolite which could be converted to aflatoxin (AF) B2 was detected during cofermentation analysis of two nonaflatoxigenic strains (SRRC 2043 and SRRC 163) of Aspergillus parasiticus. SRRC 2043, which accumulates the xanthone O-methylsterigmatocystin (OMST), a late precursor in the AFB1 pathway, was observed to accumulate another chemically related compound (HOMST; molecular weight, 356); SRRC 163 is blocked early in the pathway and accumulates averantin. During cofermentation of the two strains, levels of OMST and HOMST were observed to be greatly reduced in the culture, with simultaneous production of AFB1, AFB2, and AFG1. Intact cells of SRRC 163 were able to convert pure OMST or its precursor, sterigmatocystin, to AFB1 and AFG1 without AFB2 accumulation; the same cells converted isolated HOMST to AFB2 with no AFB1 or AFG1 production. The results indicate that AFB2 is produced from a separate branch in the AF biosynthetic pathway than are AFB1 and AFG1; AFB2 arises from HOMST, and AFB1 and AFG1 arise from sterigmatocystin and OMST.

AN - 77849669; 3686557 AB - A colorimetric method of determining cell viabilities in cultured cells is described. The system is based on the ability of mitochondrial enzymes in live but not dead cells to chemically reduce a tetrazolium salt (MTT) into a colored formazan dye which can be detected at 570 nm using a multiwell scanning spectrophotometer. 48 h Chinese hamster ovary (CHO) cell cultures are used in the assay and the amount of colored product formed is directly proportional to cell number over a range of 0.39-12.5 X 10(4) cells/ml. The cytotoxic effects of T-2 mycotoxin can also be detected colorimetrically using this method. The toxin dose which inhibits formazan formation (50% endpoint = 14-16 ng/ml) is very comparable to that which inhibits cell viability (17 ng/ml), or protein and DNA synthesis (10 ng/ml). This system also works well with mitogen-stimulated primary lymphocyte cultures but these cells exhibit a much more sensitive response to T-2 effects having a 50% inhibition endpoint of 2 ng/ml. The assay is rapid to perform and gives a high degree of precision and could serve as a valid alternative to viability assays currently in use.

AN - 77829197; 3686547 AB - T-2 mycotoxin, given to mice 4 days prior to an intraperitoneal inoculation with Listeria monocytogenes EGD, increases the acute phase response as determined by measurements of serum amyloid protein-P (SAP), and decreases the severity of the infection. Conversely, when T-2 toxin is given simultaneously with L. monocytogenes the mice become more susceptible to the infection, and the SAP levels attained are diminished relative to the non-toxin-treated Listeria-infected controls. T-2 toxin given 4 days prior to intraperitoneal inoculation with Salmonella typhimurium had no effect on either the resultant infection or SAP levels. These results indicate that T-2 toxin modulates the acute phase response to infection, and are consistent with an in vivo role for SAP as a nonspecific host resistance factor.

In general, a ground meat sample is homogenized with acetonitrile-formate buffer in the presence of dithiothreitol, and then is centrifuged, filtered, and recentrifuged in a disposable microfilter. The thiols are quantitated by liquid chromatography using an amperometric detector equipped with a gold/mercury electrode, operated in the oxidative mode. Cysteamine was found in 6 of 20 samples of raw pork belly in concentrations ranging from 150 to 450 ppb, and cysteine was found in all samples in concentrations ranging from 2.4 to 36.5 ppm. Analysis for the thiols and their corresponding nitrosamines--NTHZ and NTHZC--of bacon before and after processing showed no correlation between cysteamine and cysteine levels before processing nor with nitrosamine levels after processing.

AN - 77860117; 3121482 AB - This study was conducted to determine whether exposure to cyclopiazonic acid (CPA) and aflatoxin B1 (AFB1) would alter the toxicity associated with exposure to either toxin individually. Groups of male rats were administered 0, 0.1 or 4.0 mg CPA/kg body weight/day intragastrically (three groups per dose level) for three consecutive days and 30 min after each of these CPA doses the rats were dosed by gavage with 0, 0.1 or 2.0 mg AFB1/kg body weight/day. Six of the 12 rats given each of these nine treatments were killed on day 4 after the initial dosing, and the rest were allowed a recovery period of 4 days prior to being killed. Weight loss in the three groups receiving 2.0 mg AFB1/kg/day occurred within 24 hr of the first doses. Feed consumption by these rats was about 60% of that in the other groups. By the end of the recovery period, rats in these three groups had lost an average of 31-38 g. Feed consumption throughout the recovery period by rats in the 2.0-mg AFB1 groups was about 50% of the control value, except in the group that also received the high dose of CPA, in which it was 75%. Gross pathological findings were primarily limited to rats in the high AFB1 group, and included icterus, shrunken liver and lesions in the kidney at the cortico-medullary junction. Microscopic changes were characteristic of aflatoxicosis in rats. Glycocholic acid assays indicated liver damage only in those groups that received the high AFB1 dose. We conclude that neither toxin potentiates the action of the other at the dose levels used in this study.

The appropriateness of minor civil divisions (MCDs) as a small ecological unit in nonmetropolitan areas to measure segregation between poor & nonpoor people is examined. Using US census data, the index of dissimilarity (D) & P-type contiguity indices are evaluated for nonmetropolitan portions of Miss & Wisc. MCDs are different in the two states, which affects the interpretation of the indices. Segregation, as measured by D, is low in both states. The low value of D in Miss may have resulted from how the state's MCDs were delineated. Although the P indices are highly correlated with the poverty rate, they do provide more information than the poverty rate alone. 1 Table, 28 References.

AN - 85219941; pmid-2821800 AB - Studies on effects of fiber, phytic acid, and oxalic acid on mineral bioavailability are reviewed. It is difficult to separate the effects of fiber and phytic acid when cereal products are fed, because they occur together in these foods. However, even the combination of fiber and phytic acid does not appear to affect mineral balances unless unrefined cereal intakes are high and mineral intakes are low. Also, the body may be able to adjust to the decreased availability by increased absorption of the available mineral. Oxalic acid may result in decreases in mineral bioavailability if consumed with a high fiber diet, but the decrease may also be transient.

AN - 81116810; 3678529 AB - A multi-residue HETLC (High Efficiency Thin Layer Chromatography) screening procedure for 17 beta-oestradiol, diethylstilboesterol (DES), zearalanol (zeranol), zearalenone and their metabolites oestrone, zearalanone, and zearalenol is described. The anabolic oestrogens were analyzed on HETLC plates coated with silica gel and were developed in methylene chloride:methanol: 2-propanol (97:1:2 v/v). The spots were visualized by exposure to iodine vapours and subsequently sprayed with 1% starch solution. Analysis of standards by HETLC at 4 degrees C as a seven-component mixture showed six discrete bands with mean Rfs of 0.37 (oestrone), 0.35 (zearalanone and zearalenone), 0.26 (t-DES), 0.23 (oestradiol), 0.17 (zearalenol and zearalanol), and 0.15 (c-DES). Chicken muscle tissues (1, 2.5, or 5 g) were extracted with 95% acetone. Extracts were then fortified with 50-250 ng each of the anabolic oestrogens, purified in alumina and ion-exchange columns and analyzed by HETLC. Oestradiol, zeranol or DES in fortified tissue extracts were clearly detected when an equivalent of 4 ng were analyzed by HETLC after purification in alumina and ion-exchange columns. The intensity of their bands suggested near quantitative recovery when compared to intensity of bands of known amounts of standards. The described extraction, purification, and TLC procedures can be used to screen these oestrogens at low ppb amounts in chicken muscle tissues and should be applicable to screen tissues of cattle and sheep.

AN - 81062007; 2822734 AB - In humans the major stimulus for cutaneous pigmentation is ultraviolet radiation (UVR). Little is known about the mechanism underlying this response, in part because of the complexity of interactions in whole epidermis. Using a recently developed culture system, human melanocytes were exposed daily to a physiologic range of UVR doses from a solar simulator. Responses were determined 24 hours after the last exposure. There was a dose-related increase in melanin content per cell and uptake of 14C-DOPA, accompanied by growth inhibition. Cells from donors of different racial origin gave proportionately similar increases in melanin, although there were approximately tenfold differences in basal values. Light and electron microscopy revealed UVR-stimulated increases in dendricity as well as melanosome number and degree of melanization, analogous to the well-recognized melanocyte changes following sun exposure of intact skin. Similar responses were seen with Cloudman S91 melanoma cells, although this murine cell line required lower UVR dosages and fewer exposures for maximal stimulation. These data establish that UVR is capable of directly stimulating melanogenesis. Because cyclic AMP elevation has been associated in some settings with increased pigment production by cultured melanocytes, preliminary experiments were conducted to see if the effects of UVR were mediated by cAMP. Both alpha-MSH and isobutylmethylxanthine (IBMX), as positive controls, caused a fourfold increase in cAMP level in human melanocytes and/or S91 cells, but following a dose of UVR sufficient to stimulate pigment production there was no change in cAMP level up to 4 hours after exposure. Thus it appears that the UVR-induced melanogenesis is mediated by cAMP-independent mechanisms.

The tradeoffs between the costs of soil conservation practices and water quality are reported, and the economic implications of such tradeoffs are discussed. Soil and nutrient losses resulting from crop production practices are analyzed using a field-scale computer simulation model (CREAMS). No-till planting, reduced tillage, and sod waterway systems are more cost effective than other practices for controlling soil and nutrient runoff losses. Nitrate leaching losses are increased slightly by most soil conservation practices. Terrace systems and permanent vegetative cover impose the greatest societal cost for water quality protection. Public cost sharing and tax incentives encourage farmers to adopt expensive structural practices, and policies are needed to get cost-effective practices implemented on critical acreage.

AN - 77861065; 3690425 AB - Previous studies have established that aflatoxin production is induced by high levels of glucose (or other compatible carbohydrates). However, the minimal amount of glucose needed to achieve this effect had not been determined. Aspergillus parasiticus was induced to produce aflatoxin when incubated for 18 h in the presence of greater than or equal to 0.1 M glucose before addition of cycloheximide. Toxin formation was not induced at any glucose concentration in the mycelia incubated for 8 h. These results suggest that aflatoxin synthesis would not be expected in substrate containing less than 0.1 M of a carbohydrate source.

The most sensitive species tested was Schizaphis graminum (Rondani), the least sensitive was Acyrthosiphon pisum (Harris). Myzus persicae (Sulzer) was of intermediate sensitivity. Ellagic acid (ED50 = 15 ppm) and n-decyl gallate (ED50 = 16 ppm) were particularly potent against S. graminum, while n-octyl gallate was the most active compound tested against A. pisum (ED50 = 182 ppm) and M. persicae (ED50 = 56 ppm). The ellagitannins, geraniin and pedunculagin, were active against S. graminum and M. persicae, but not against A. pisum. Methylation of the free hydroxyl groups of gallic acid resulted in a large decrease in activity, while esterification of its carboxyl group with alkyl chains of increasing length resulted in increasing activity against S. graminum. Against A. pisum and M. persicae, ellagic acid, gallic acid and 3,4,5-trimethoxybenzoic acid were inactive, whereas pyrogallol and the gallate esters were at least moderately active as feeding deterrents.Original Abstract: Action repulsive des ellagitanins, de leurs produits phenoliques d'hydrolyse et de derives phenoles voisins, sur les pucerons. L'examen a porte sur l'action repulsive, lors de l'alimentation de trois especes de pucerons, de l'acide ellagique, de deux ellagitanins, de l'acide gallique, du pyrogallol et de plusieurs derives de l'acide gallique. Schizaphis graminum Rondani a ete l'espece la plus sensible, tandis que Acyrthosiphon pisum Harris a ete la moins sensible; la sensibilite de Myzus persicae Sulzer etait intermediaire. L'acide ellagic (ED50 = 15 ppm) et le n-decyl gallate (ED50 = 16 ppm) ont ete particulierement actifs contre S. graminum, tandis que le n-octyl gallate a ete le produit le plus actif contre A. pisum (ED50 = 182 ppm) et M. persicae (ED50 = 56 ppm). Les ellagitanins, geraniine et pedunculagine ont ete actifs contre S. graminum et M. persicae, mais pas contre A. pisum. La methylation des groupes hydroxyl libres de l'acide gallique a reduit fortement l'activite, tandis qul'esterification de son groupe carboxyl avec des chaines alkyl de longuers croissantes a augmente l'activite contre S. graminum. Les acides ellagique, gallique et 3,4,5-trimethoxybenzoique ont ete inactifs contre A. pisum et M. persicae, tandis que le pyrogallol et les esters de gallate on ete pour le moins des repulsifs moderement actifs au cours de l'alimentation.

AN - 81057773; 3116930 AB - Two activities involved in terminal pathway conversion of sterigmatocystin to aflatoxin B1 were isolated from an aflatoxin-nonproducing mutant of Aspergillus parasiticus (avn-1), and the time course of appearance of the activities in culture was determined. Subcellular fractionation of fungal mycelia resolved the two activities into a postmicrosomal activity which catalyzed conversion of sterigmatocystin to O-methylsterigmatocystin and a microsomal activity which converted O-methylsterigmatocystin to aflatoxin B1. The two activities were absent in 24-h-old cells, increased to optimum levels during the stationary phase, and then declined.

Leaf Tissue. AN - 733491794; 16665360 AB - The intracellular distribution of the neurotoxin 2,4-diaminobutyric acid (DABA) in mature leaves of the perennial legume Lathyrus sylvestris L. var ;Lathco' (flatpea) was determined using subcellular fractions from mesophyll protoplasts. Chloroplasts contained about 15% of the cellular DABA. At least 75% of the DABA was vacuolar, based on the assumptions that each protoplast contained a single vacuole and that acid phosphatase occurred exclusively in the vacuole. DABA was not detectable in peroxisomal and mitochondrial fractions. Because the vacuole is not a major site of amino acid synthesis, this distribution implicates synthesis of DABA within chloroplasts with subsequent transport to and storage within the vacuoles of the mesophyll cells.

AN - 733492589; 16665286 AB - Aluminum is a major constituent of most soils and limits crop productivity in many regions. Amelioration is of theoretical as well as practical interest because understanding amelioration may contribute to an understanding of the mechanisms of toxicity. In the experiments reported here 2-day-old wheat (Triticum aestivum L. cv Tyler) seedlings with 15-millimeter roots were transferred to solutions containing 0.4 millimolar CaCl(2) at pH 4.3 variously supplemented with AlCl(3) and additional amounts of a chloride salt. Root lengths, measured after 2 days in the test solutions, were a function of both Al activity and the cation activity of the added salt. Percent inhibition = 100 {Al(3+)}/({Al(3+)} + K(m) + alpha{C}(beta)) where {Al(3+)} is the activity of Al(3+) expressed in micromolar, {C} is the activity of the added cation expressed in millimolar, and K(m) (= 1.2 micromolar) is the {Al(3+)} required for 50% inhibition in the absence of added salt. For Ca(2+), Mg(2+), and Na(+) the values of alpha were 2.4, 1.6, and 0.011, respectively, and the values for beta were 1.5, 1.5, and 1.8, respectively. With regard to relative ameliorative effectiveness, Ca(2+) > Mg(2+) approximately Sr(2+) >> K(+) approximately Na(+). Other cations were tested, but La(3+), Sc(3+), Li(+), Rb(+), and Cs(+) were toxic at potentially ameliorative levels. The salt amelioration is not solely attributable to reductions in {Al(3+)} caused by increases in ionic strength.

Although this aquifer is not a principal source for potable water, questions of quality and quantity of groundwater remain a concern, primarily due to the enormous economic impact of irrigated agriculture. Recent studies indicate that localized shortages may occur in the central delta region. Just over 1 billion gallons of water per day is pumped from the ground for rice, catfish, cotton, and soybean production. This is two times the daily consumption of the cities of Jackson, Tupelo, and Vicksburg combined. To help Mississippi farmers use their water resources most efficiently, the USDA-Soil Conservation Service initiated an Irrigation Water Management (IWM) program in the summer of 1985. The initial thrust of the irrigation team has been directed toward evaluating the performance of existing center-pivot irrigation systems for water and energy use efficiency and the intake characteristics of the soil under these systems. There are approximately 1000 center pivot systems in the delta. One center pivot system pumping 1200 gpm will pump 1-3/4 million gallons/day, which is the equivalent to the water use of the town of Indianola. The irrigation team is also responsible for updating the Mississippi irrigation guide with information on the intake capability of different soils under different cropping patterns. Briefly explained here are the 1986 test methods, accomplishments, and goals of the IWM team. The work performed indicates that irrigation systems are being designed on values of infiltration that are inaccurate and outdated. A center pivot evaluation increases a farmer 's ability to manage his crops. Compaction is undoubtedly a widespread problem. Compaction can limit the amount of rainfall stored by the soil, thereby increasing the demand on groundwater supplies.
