Abstract: An investigation was carried out to study the occurrence and biopesticidal management of shoot and fruit borer, Leucinodes orbonalis (Guenee) in brinjal during kharif 2014 at Crop Research Centre, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut. Eight different insecticides were tested in a randomized block design with three replications. During the crop season, ten insect species were found attacking the brinjal crop at different crop growth stages. Of these, shoot and fruit borer, Leucinodes orbonalis (Guenee) and whitefly, Bemisia tabaci (Gennadius) were recorded as major pests. The jassid, Amrasca biguttula biguttula (Ishida) and aphid, Aphis gossypii (Glover) were found to damage the crop moderately. The other insect pests recorded on the crop were of less importance. The incidence of shoot and fruit borer recorded first on second fortnight of July and reached to its peak during middle of October. The population of L. orbonalis showed positive correlation with the maximum and minimum temperature, while, relative humidity and rainfall had negative correlation. Efficacy of different treatments viz, spinosad 45SC @ 200ml/ha, Beauveria bassiana 1X108 spore/gm @ 2500gm/ha, chlorpyrifos 20EC @ 1lit/ha, neemarin 35% W/W @ 3lit/ha, Bacillus thuringiensis var. kurtsaki 54% 500gm/ha, neemarin-Bt- Bb and Bt - Bb – Bt against L. orbonalis revealed that all the treatments were found significantly effective in reducing the infestation of shoot and fruit borer and thus increasing the yield as compared to control. The most effective treatment was spinosad 45SC @ 200ml/ha followed by chlorpyrifos 20EC @ 1lit/ha. The higher yield (169.13q/ha) and cost benefit ratio (1: 10.62) were also obtained from spinosad 45SC.
