Abstract
Eclosion, longevity, and reproduction of three braconid parasitoid species that parasitized tephritid fruit flies exposed to azadiracthin were determined. Psytallia incise (Silvestri) and Diachasmimorpha longicaudata (Ashmead) developed in and eclosed from oriental fruit flies, Dacus dorsalis Hendel, exposed to azadirachtin concentrations that completely inhibited adult fly eclosion. Diachasmimorpha tryoni (Cameron) also eclosed from Mediterranean fruit fly, Ceratitis capitata (Wiedemann) exposed to concentrations of azadirachtin that inhibited fly eclosion. Lifespans of parasitoids that emerged from treated flies were not significantly different from controls. Reproduction of P. incisi that developed in flies exposed to azadirachtin concentrations of > 20 ppm was reduced 63-88%. D. longicaudata and D. tryoni reproduction was unaffected. The potential use ofneem-based insecticides in conjunction with biological control programs is discussed.Keywords
