Abstract
Field experiment was conducted to evaluate the efficacy of egg parasitoid, Trichogramma chilonis Ishii against sugarcane Plassey borer Chilo tumidicastalis Hampson. It was observed that the incidence of C. tumidicostalis in chemical control plot was 15.02% in comparison to 11.49% in parasitoid released plot. These revealed a significant difference between the treatments resulting in 55.77% reduction in damage. The mean % parasitism of eggs of C. tumidicostalis in parasitoid released plot was 28.13% as against 9.85% in chemical control plot. The cane yield attributed in parasitoid released plot was 74.15 t/ha as compared to 69.23 and 49.74 t/ha in chemical and untreated plots, respectively. A net return of Rs. 101221/ha was achieved in the parasitoid released plots as against Rs. 87179/ha in case of chemical control plot. Maximum cost benefit ratio was obtained with T. chilonis released plot (1:2.15) followed by chemical control (1:1.70).
