%X Eggplant Shoot and Fruit Borer (ESFB), Leucinodes orbonalis Guenee, is an economically important pest in Bangladesh. Different toxic chemical insecticides are frequently applied in the field to control this notorious pest. In this study, we tested several non-toxic microbial insecticides for their efficacy against ESFB as well as marketable yield. Abamectin 1.2% + Emamectin benzoate 1%, Spinosad 45 SC and Bacillus thuringiensis var. Kurstaki 5% WP significantly prevents shoot infestation compared to control. Fruit infestation was also reduced by Abamectin + Emamectin benzoate, Spinosad 45 SC, and Bacillus thuringiensis var. Kurstaki 5% WP, in contrast, to control by both number and weight basis, respectively. Marketable yield increased exponentially upon Spinosad 45 SC and Abamectin 1.2% + Emamectin benzoate 1% application. Finally, gross yield also increased notably by Spinosad 45 SC application. From this study, we found that all the microbial insecticides especially Spinosad 45 SC and Abamectin 1.2% + Emamectin benzoate 1% found effective to reduce ESFB infestation both in the shoot and fruit. These also increase the marketable fruit yield by increasing the healthy fruit weight and decreasing the infested fruit weight individually.
