Abstract

Regular survey for the parasitoids of Helicoverpa armigera (Hübner) in chickpea ecosystem was conducted during post-winter months (March-April) in Kanpur (Uttar Pradesh, India) during 2006-2008 cropping seasons. Fourth and fifth instar larvae of H. armigera were found parasitized by Bracon hebetor Say (Hymenoptera: Braconidae). The per cent parasitization of B. hebetor on H. armigera larvae in chickpea ecosystem ranged from 0.24 to 1.59 under field conditions. This is the first record of B. hebetor from chickpea ecosystem. A study was also conducted on the effect of adult diets on the longevity of the parasitoid. Highest longevity of 34.7 days in case of female and 22.0 days in case of male was recorded when fed with 50% honey solution.
