Abstract

The feeding inhibition (FI) of different natural products viz., Neemastra, Agniastra, Brahmastra and garlic + chilli extract was evaluated against the third and sixth instar larvae of Agrotis segetum (Denis & Schiffermuller). The concentrations tested ranged from 2 to 32 per cent. The mortality due to natural products was found to be non significant in third and sixth instar larvae but resulted in significant feeding inhibition (FI). Based on FI50 values, the order of feeding inhibition of the natural products tested against the third and sixth instar larvae was observed as Brahmastra (5.81 and 6.61%) > Neemastra (6.12 and 7.04%) > garlic + chilli extract (6.39 and 7.49%) > Agniastra (6.44 and 8.62%), respectively.
