<![CDATA[Antifeedant activity of neem leaf (A. indica A. Juss) has been identified by against Tenebrio molitor bio-indicator. The highest activity was obtained on ethyl acetate extract at 0.5% concentration having Antifeedant Index (AI) of 51.53% and most active at 10% concentration of 82.05%. The method used to test the antifeedant activity is the no choice leaf disk method. Secondary metabolites contained in neem leaf extract (A. indica A. juss) include terpenoids, steroids, flavonoids, saponins and phenolics.
