Abstract: Field study was conducted to determine the insecticides and biopesticides were applied as foliar spray to manage the infestation of gram pod borer of chick pea. The insecticides were applied when there was appearance of gram pod borer, average population from 0.1-1.1 per plant. Estimation of losses in yield due to infestation by gram pod borer of chick pea in Kabirdham district. The efficacy of insecticides, Biopesticides and Bird perchar on mean caterpillar population differed considerably. The mean number of gram pod borer before spray varied from 0.1-1.1 per plant but when the treatments were applied there was drastic reduction in overall mean population of gram pod bore. The gram pod borer overall mean population was considerably less in replication RI, overall mean population 0.18 per plant which was treated in Endosulphan. RII, overall mean population 0.17 per plant which was treated in Chlorpyriphos + Cypermethrin (Super D). RIII, overall mean population 0.13 per plant which was treated in Endosulphan. However, the gram pod borer overall mean population was maximum in RI, 0.33 per plant which was NPV treated as compared to 0.38 per plant mean population of gram pod borer in control. RII, 0.28 per plant which was Azadirachtin (Neemplex) and Bird perchar treated as compared to 0.31 per plant mean population of gram pod borer in control. RIII, 0.36 per plant which was Bird preacher treated as compared to 0.41 per plant mean population of gram pod borer in control. The Overall mean population of gram pod borer in RI, RII and RIII, was minimum 0.17 per plant Endosulphan treated as compared to 0.37 per plant overall mean population of gram pod borer in control. The effect of insecticide/ bio insecticides and bird preacher on mean yield in qt. /ha is also varied greatly. The mean yield in qt. /ha was maximum 5qt./ha which was Quinalphos treated while minimum was 4.33qt./ha which was Endosulphan treated as compared to 3.78qt./ha yield in control.
