ABSTRACT

Population of gram pod borer Helieoverpa armigera (Hubn.) and their biological suppressing agents were studied at four places. Maximum pod borer population (10.8 ± 4,9 larvae/m2) was recorded at Bhendari followed by Chamari (9.8±3.1 larvae/m2). Natural enemy play a key role in population suppression of pod borer and during peak 52.7 to 90.1% parasitization were noticed in different location. Among natural enemy recorded, fungi, Beauvaria bassiana Balsamo and ichneumonid, Campoletis chlorideae Uchida were dominant and during their peak infectivity were ranged from 2.4± 1.8 to 5.0±4.0 infected larvae/m2 and from 1.8±1.0 to 4.0± 1.5 diseased larvae/m2 at different Eriborus sp. were minor in status.
