Antifeedant Effects of Citrus Limonoids Differing in A-Ring Structure on Colorado Potato Beetle (Coleoptera: Chrysomelidae) Larvae Journal of Economic Entomology (1991)
The antifeedant effects of three citrus limonoids (limonin, obacunone, and nomilin) which differ only in the structure of the A-ring were compared in feeding assays with fourth-instar Colorado potato beetles, Leptinotarsa decemljneata (Say). In contrast ...
Developmental Rates, Thresholds and Thermal Constants of the Egg Parasitoid Anastatus semiflavidus (Hymenoptera: Eupelmidae) and Its Host Hemileuca oliviae (Lepidoptera: Saturniidae) Journal of Kansas Entomological Society (1989)
The effects of temperature on the development of the egg parasitoid, Anastatus semiflavidus Gahan (Eupelmidae, Hymenoptera), and its host the range caterpillar, Hemileuca oliviae Cockerell (Saturniidae, Lepidoptera), were examined. The egg of H. oliviae had ...
