To study biorational approaches for the management of brinjal shoot and fruit borer

The present work entitled “Studies on insect-pests succession and biorational management with special reference to Leucinodes orbonalis (Guenee) on brinjal”was carried out at the Entomology Field, in RMD College of Agriculture & Research Station, Ambikapur, Chhattisgarh during the Kharif season of 2024-25 In this study, several biorational treatments was cmpared. Emamectin benzoate had the lowest rate of brinjal shoot and fruit infestation (3.26%), followed by Bacillus thuringiensis (3.78%), Beauveria bassiana (4.21%), Metarhizium anisopliae (4.84%), Nimbicidine (5.66%), and Verticillium lecanii (6.12%). Emamectin benzoate > Bacillus thuringiensis > Beauveria bassiana > Metarhizium anisopliae > Nimbicidine > Verticillium lecanii > Control plot was the order of the effective treatment. Some biopesticides, especially Bacillus thuringiensis, Beauveria bassiana and Metarhizium anisopliae showed comparable effectiveness over the long term.
