Abstract

Investigations were carried out to determine the infectivity of Steinernema carpocapsae recovered from rice moth (Corcyra cephalonica), greater wax moth (Galleria mellonella), gram pod borer (Helicoverpa armigera) and tobacco caterpillar (Spodoptera litura) against S. litura at different temperature under laboratory conditions. The experimental results revealed that at 300C maximum (100.00) percent mortality of S. litura was achieved within 96 hrs of inoculation of S. carpocapsae obtained from S. litura. Whereas, the populations recovered from other hosts viz. G. mellonella, H. armigera and C. cephalonica caused (100.00) percent mortality after 120 hrs of inoculation.
