Abstract:
... The presence of adult Cardiochiles nigriceps Viereck, a nearly obligatory parasitoid of tobacco budworm larvae, Heliothis virescens (F.) (Lepidoptera: Noctuidae), was monitored in fields with up to 117 accessions of Nicotiana species (Solanaceae) during 1985-1994 at Oxford, NC, Tifton, GA, and Athens, GA. Large numbers of wasps were observed flying over or reefing on several Nicotiana species, esp ...

Abstract:
... Northern Belize has extensive herbaceous wetlands. Those dominated by sparse emergent macrophytes, rushes (Eleocharis spp.) and sawgrass (Cladium jamaicense Crantz), often develop floating mats of cyanobacteria (blue-green algae). These mats provide suitable habitat for larvae of the malaria transmitting mosquito Anopheles albimanus Wiedemann. Presence/absence of A. albimanus larvae and cyanobacte ...

A series of assays were set up to evaluate several parameters affecting rubidium assimilation, excretion and effects on migratory grasshopper, Melanoplus sanguinipes (F.), development following ingestion of RbCl. Dosages of RbCl as high as 3.82 mg were found to elevate tissue concentrations of Rb as much as 4,900 ppm above background levels at 2 d after ingestion. The rate of ingestion was essenti ...

Abstract:
... Larval host associations in luperine rootworm beetles (Chrysomelidae), including the many pest species in the subtribes Diabroticina and Aulacophorina, remain largely unknown because adults often feed on plant species and families other than those favored for larval development. Because important questions concerning the evolutionary origins, systematic relationships, and pest management of luperi ...

Abstract:
... Insect herbivores that have high impacts on their host plants reduce the longevity of their habitats and require dispersal mechanisms. This hypothesis was tested by comparing the life history traits, particularly short- and lone-distance dispersal mechanisms, of 5 aphid species in relation to their impact on barley, Hordeum vulgare L. The aphids were bird cherry-oat aphid, Rhopalosiphum padi (L.), ...

Our results indicate that within 8-m3 arenas, large and small moths do not show assortative mating or preference for one size class over another. Within the same arenas, nonrandom mating did occur based on mating history coupled with age. Biologicall ...

Previous studies demonstrated that early in the growing season, E. terebrans adults are more abundant, and parasitize a greater proportion of O. nubilalis larvae, near wooded edges of cornfields. We hypothesized that E. terebrans requires a sourc ...
