Abstract

Multiplication rate of Steinernema feltiae Filipjev (DD-136 strain) on Corcyra cepbelonica (Staint.) larva was significantly influenced by the inoculum level with ten dauers per larva being the optimum for maximum multiplication. The relationship between the inoculum level and multiplication was curvilinear. The infectivity of the nematode to C. cephalonica was on a par at 25 and 30 °C, significantly less at 33°C and nil at 35 °C. Multiplication of the nematode was maximum at 25°C, signifincantly less at 30°C and absent at 33°C.
