The population was recorded at different days after spraying of insecticides and it was found that the number of larvae varied non- significantly different from the control in both spray application. Significant effect of bio-pesticides on per cent webbing by M. vitrata, at First spray application showed minimum (32.00/25shoots) in NSKE 5.0 % @ 50 g/lit .The pod borer M. vitrata was found lowest in Spinosad 45%ww @73g.ai/ha (4.50%) , followed by NSKE 5 % (4.81%) and B. bassiana DOR SC @ 1.89gm/lit (5.39%) as compared to control (14.49%). The per cent pod damage by H. armigera varied significantly which was minimum (27.84%) in Spinosad 45%ww @73g.ai/ha followed by B. bassiana WP @ 1.5kg/ha (28.58%) and B. bassiana DOR SC @ 1.89gm/lit (28.73%) in comparison to control (51.68%). Grain yield varied from maximum of 1200 kg/ha in Spinosad 45%ww @73g.ai/ha followed by 1191.67 kg/ha in B. bassiana DOR SC @ 1.89gm/lit as compared to 708.33kg/ha in untreated control.
