Abstract


Experiments were conducted to study the influence of intercrops in chickpea on natural enemies of gram pod borer, Helicoverpa armigera (Hubner) and to monitor the adult population through pheromone traps. Highest chickpea equivalent grain yield was recorded in chickpea + mustard (6:2) during both the seasons followed by chickpea + barley (4:2) during rabi 2004-05 and chickpea + linseed / chickpea + coriander (4:2) during 2006-07. Pod damage by H. armigera was highest in chickpea sole crop. Parasitization by Campoletis chloridae (Uchida) did not vary with the intercrops during pre-winter months of rabi 2004-05 while, parasitization was higher in chickpea + linseed during rabi 2006-07. H. armigera catches in pheromone traps was peak during 14-15th standard week.
