Abstract

Abstract: Millettia pachycarpa (Bentham), a perennial climbing tree, found endemic in north-east India used by tribes for treating various ailments. To ascertain the potential of M. pachycarpa for pest management, the present investigation was formulated against a polyphagous pest, Spodoptera litura (Fabricius). Growth inhibitory activity of various extracts and extract fractions was evaluated against third instar larvae of S. litura through topical as well as diet incorporation method. It was observed that dichloromethane extract showed very good growth inhibition in both topical (GI50 7.77 ppm) and diet incorporation methods (GI50 < 5 ppm). The growth inhibitory potential of this plant is also demonstrated by the presence of various abnormalities and reduction in larval and pupal weight.
