We conducted laboratory and field studies to gain new understanding of biology and biocontrol potential of Campoletis chlorideae Uchida on Helicoverpa armigera (Hubner). Development time, adult longevity and fecundity of parasitoid were studied at 28±2℃ and 70±10% RH. It was revealed that the parasitoid laid on an average 13.40±3.02 and 42.00±2.21 eggs after single mating and throughout its life span, respectively. The egg-larval and pupal period was 13.5±0.45 and 7.0±0.44 days, respectively. The emergence rate varied from 78.3 to 85.2%.
