The Effects of Azadirachtin on the Percentage of Glycogen Contents in Larvae of Galleria mellonella

The most active ingredient against insects, azadirachtin, a tetranortriterpenoid, manifests antifeedant,growth regulatory and fecundity-reducing properties in insects. Effects of azadirachtin extracts obtainedfrom ripe fruits, seeds, trunk and flower of Melia azedarach and Azadirachta indica on total glycogen amountof 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.Azadirachta indica; azadirachtin; Galleria mellonella; glycogen
