A study on the antifeedant activity of Cassia fistula leaves

Abstract

Plant derived metabolites as molecule to counter the damage caused by pests has been a usual way of practise in the traditional method of farming. It is the most sought method as it has reduced effect on the human and environment than the conventional pesticides. In this study the leaves of Cassia fistula were screened for active phytochemicals using various solvents namely petroleum ether, chloroform, ethanol and methanol. The bioactivity of the molecules of these extracts were analysed as feeding deterrent activity against Sitophilus granarius. The antifeedant indices for all the extracts were dose dependent. The greatest effect for feeding inhibition was observed for petroleum ether extract having the highest value followed by ethanol.
