The Present study revealed that the incidence of eggs, I^st to III^rd instar larvae, IV^th and V^th instar larva, pre-pupal larva of H. armigera was observed from 49^th MW to 4^th MW, 48^th to 4^th MW, 49^th to 4^th MW, 49^th MW to 3^rd MW respectively. While studying the various life stages, parasitoids viz., Eriborus spp. and Campoletis chlorideae, NPV and other reasons were found the most effective mortality factors. The overall mortality in I^st to III^rd, IV^th to V^th instar larvae, pre-pupal larva, and pupa was 30.77 and 31.37 15.49, and 31.67 per cent respectively due to different reasons viz., unknown, incomplete pupation and HaNPV, pupal deformities (no adult emergence). The Male: Female sex ratio was 1:1.35. The adult emergence was 68.33 per cent and the fecundity observed was 409.64 eggs/female.
