Studies were conducted to assess the role of natural mortality factors in Helicoverpa armigera (Hubner) on chickpea in Punjab. The larval parasitoid Campoletis chlorideae Uchida has been recorded as the most important mortality factor. Parasitism due to C. chlorideae ranged from 0.98 to 68.50 per cent throughout the crop season. The maximum parasitism was recorded during 3rd week of February, 1999 when the minimum mean temperatures and relative humidity were 11.9[degree]C and 95 per cent, respectively. As C.chlorideae helps in suppressing the pest population both at vegetative and flowering/pod formation stage of the crop, it suggests that the conservation of C. chlorideae in chickpea is important. none
