The gram pod borer, H. armigera started appearing on gram crop during the fourth week of October and touched the peak in the third week of November. The gram pod borer reappeared in the last week of December and reached to a peak in the first week of February. The larval population of Helicoverpa armigera was positively correlated to the atmospheric temperature, but negatively correlated to the relative humidity, though the correlation coefficient values were non-significant. Parasitization was observed in November and the maximum parasitization (24%) due to larval parasitoid, Campoletis chloridae Uchida was recorded in the last week of November; whereas in February the gram Caterpillar parasitization (20%) was recorded due to pupal parasitoid, Carcelia illota Curran. The efficacy of different bio-pesticides in a descending order were as follows: M. anisopliae (oil formulation) > M. anisopliae (aqueous formulation) > M. anisopliae (water emulsion) > Karanj oil 2% > Pseudomonas aeruginosa > Neem oil 2% > NSKE 10%.ennullThesis
