Abstract

The extent of natural parasitism of Helicoverpa armigera (Hubner) by Campoletis chlorideae Uchida on different chickpea cultivars was studied at different locations in Jalandbar district of Punjab. The parasitoid population varied from 0.02-1.S0 cocoons per metre row length and the larval population ranged between 0.86-14.50 larvae per metre row length. The maximum numbers of cocoons were recorded on PBG S (0.88) followed by L SSO (0.74). The H. armigera population was also high on PBG S (9.38 larvae I m row length) followed by L 550 (6.75 larvael Ul row length).
