The virulence of Steinernema feltiae Filipjev to Spodoptera litura Fab. (Noctuidae: Lepidoptera) and Heliothis armigera Hbn. (Noduldae: Lepidoptera) was reduced as the temperature lnaeased from 24 to 30 °C. Between the two insects, H. armigera was more susceptible than S. litura. The LC50 values for both the insects were higher at the final instar when compared to the third instar.Keywords
