The most active ingredient against insects, azadirachtin, a tetranortriterpenoid, manifests antifeedant, growth regulatory and fecundity-reducing properties in insects. Effects of azadirachtin extracts obtained from ripe fruits, seeds, trunk and flower of Melia azedarach and Azadirachta indica on total glycogen amount of Galleria mellonella was studied. Total glycogen synthesized were measured when the larvae reached their last larval stage after feeding them during 3rd stage with 1.00, 2.00, 4.00 and 6.00 mL/100 g azadirachtin compared with control insects while 33%, 42% and 50% decrease were observed in individual fed with 2.00, 4.00 and 6.00 mL/100 g azadirachtin containing feed respectively.
