Abstract: 
Azadirachtin, a potent antifeedant and growth regulator from the neem tree, Azadirachta indica A. Juss, was tested against 3 holometabolous insects belonging to different orders: Mexican bean beetle, Epilachna varivestis Muls.; Mediterranean flour moth, Ephestia kuehniella Zell.; and honeybee, Apis mellifera L. Different amounts of azadirachtin were either fed (E. varivestis, 4th instar larvae) or topically applied (E. kuehniella, last larval instar, spinning stage; A. mellifera, 3rd instar larvae) to the test insects. The larval development to adults was reduced and the reduction was dose-dependent; pupal mortality was also observed. Weight gains were comparable with control larvae, indicating no feeding inhibition. The effect of azadirachtin on larval-pupal and pupal-adult molts is interpreted as an interference with molting hormone pools.
