摘要: Neem is derived from the neem tree Azadirachta indica A. Juss. (Meliaceae), and its primary insecticidal component tetranortriterpenoid azadirachtin other limonoids. The effect of limonoids azadirachtin, salannin, deacetylgedunin, gedunin, 17-hydroxyazadiradione deacetylnimbin on enzyme lactate dehydrogenase (LDH) activity rice leaffolder (RLF) Cnaphalocrocis medinalis (Lepidoptera: Pyralidae) larvae was investigated. There a decrease in relative to control at all concentrations tested. When fed diet leaves treated with bioassays, gut tissue enzyme, LDH levels are affected. These results indicate affect activity. effects most pronounced early instar larvae. Azadirachtin potent experiments indicating strong inhibition. Clear dose-response relationships were established respect
