Studies on resistance of rice to Sogatodes oryzicola (Muir) and a parasitoid, Haplogonatopus sp., in Costa Rica

Creator:: Alvarez B., Francisco
Abstract:: Twenty-one rice cultivars were evaluated to determine the difference between populations of Sogatodes oryzicola (Muir) (Homoptera: Delphacidae) in Costa Rica and Colombia, Survival, mortality and population development of S. oryzicola on five selected cultivars was used to determine levels of plant resistance. The importance and potential of the parasitoid-predator Haplogonatopus...

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...

A systematic study of the genus Phytocoris Fallén (Heteroptera:Miridae) in western North America

Creator:: Stonedahl, Gary Michael
Abstract:: The western Nearctic species of the genus Phytocoris Fallen were taxonomically revised. Over 15,000 specimens were examined. Information concerning host plant associations and distributions was compiled and summarized for use by future researchers. External morphological features and characters of the male genitalia were used to distinguish species. The genital tubercles...

Gamma irradiation of the western cherry fruit fly for the sterile male control technique

Creator:: Brown, Robert David
Abstract:: The western cherry fruit fly, Rhagoletis indifferens Curran, was studied to determine the suitability of the sterile insect technique for its control. To obtain insect material, field collection of maggots is preferred to sifting of soil or rearing on artificial diet. The western cherry fruit fly is strictly univoltine; only...

A three-trophic-level perspective on factors influencing herbivore abundance on collard

Creator:: McIver, James D.
Abstract:: The influence of natural enemies and plant apparency in determining the abundance of the cabbage aphid Brevicoryne brassicae L. and the imported cabbageworm Pieris rapae L. was examined on collards grown in a collard monoculture and in a collard-alfalfa biculture. This design was used to examine the factors affecting collardherbivore...
