Resistance in snap beans, Phaseolus vulgaris L., to adult western spotted cucumber beetle, Diabrotica u. indecimpunctata Mann

Creator:: Eltoum, Elameen M. A.
Abstract:: Studies to evaluate resistance in snap beans, Phaseolus vulgaris L. to adult western spotted cucumber beetles, Diabrotica u. undecimpunctata Mann. were conducted in greenhouse cages, field cages, field plots, and in temperature controlled cabinet in the laboratory. Results showed that there were differences in susceptibility to adult feeding injury between...

Oil sprays to prevent the spread of bean yellow mosaic virus (BYMV) by aphids

Creator:: Vargas, Timothy Carl
Abstract:: The influence of oil sprays on the field spread of the aphid-borne bean yellow mosaic virus (BYMV) in bean was studied in 1972 and 1973. Oil sprays failed to significantly reduce virus spread in the 1972 BYMV experiment. However, the data did suggest that the efficiency of the oil sprays...

Riparian and adjacent upslope beetle communities along a third order stream in the western Cascade Mountain Range, Oregon

Creator:: Brenner, Gregory John
Abstract:: Monitoring wildlife habitats has become important to forest ecosystem management because it provides valuable information about the response of forests and their species to harvest practices, impacts from recreational use, conservation efforts, and natural and human-caused disturbances. Monitoring is a complex task that requires a variety of abiotic and biotic...

Use of petroleum oils to prevent spread of stylet-borne viruses by aphids

Creator:: Ascerno, Mark E.
Abstract:: The use of petroleum oil prevented, to varying degrees: the transmission of three stylet-borne viruses in three different crops. The use of oils resulted in a marked improvement in the number of lily bulbs harvested from treated plots as compared to the number of lily bulbs harvested from untreated plots....

Conservation of arthropod natural enemies in broccoli with relay strip-cropping

Creator:: McGrath, Daniel M. (Daniel Morton)
Abstract:: Relay strip-cropping combines two vegetation management tactics, under-sowing and strip-management. In this study conducted from 1994 though 1997, a cover crop seed-mixture containing oats (Avena sativa L. var. "Monida"), common vetch (Vicia sativa L.), red clover (Trifolium pratense L.), annual ryegrass (Lolium multflorum Lam.), and buckwheat (Fagopyrum esculentum Moench) was...

Effects of early season immigration on acaricide resistance of Tetranychus urticae Koch on strawberry in the California Pajaro and Salinas valleys

Creator:: Miller, Richard W. (Richard William), 1958-
Abstract:: In the Pajaro Valley near Watsonville, California, twospotted spider mite (Tetranychus urticae Koch) populations were surveyed in 1983 and '84 to detect the influence of immigrants from nursery plants or surrounding vegetation on subsequent resistance development to cyhexatin and formetanate in strawberry fields. Susceptible mites (cyhexatin LC50 = 0.0039 %...

Population development of Scutigerella immaculata (Newport), in laboratory and greenhouse cultures

Creator:: Ramsey, Henry Lee
Abstract:: Population development of the symphylan, Scutigerella immaculata (Newport), was studied in laboratory cultures. Also symphylan injury to greenhouse plants was investigated. Plastic polyethylene containers partly filled with damp ground hemlock bark were used to culture symphylan in the laboratory. Fresh lettuce food was supplied to the cultures weekly. Factors which...

Effects of tillage on emergence of mint root borer, Fumibotys fumalis Guenée, and on other agronomic factors in peppermint, Mentha piperita L.

Creator:: Talkington, Michael Lee
Abstract:: Studies were conducted in the Willamette Valley of western Oregon to evaluate the effects of plowing (7.5-15 cm deep) and disking (5-10 cm deep) in peppermint, Mentha piperita L., on the following factors: 1) emergence of adult "mint root borer", Fumibotys fumalis Guenée; 2) suppression of common groundsel, Senecio vulgaris...
