To find out the bioefficacy of different groups of insecticides, viz., Chitin inhibitor-Novaluron, O.R-profenofos, carbamate-thiodicarb, neo-nicotinyl-acetamiprid, thio-urea-diafenthiuron and microbial-Bt, against Brinjal shoot and fruit borer, Leucinodes orbonalis two field trials were conducted during 2000 and 2001. All the chemicals applied at two doses were found to result in significant reduction of infestation and increased yield over untreated control. Novaluron applied at 37.5 g ai/ha resulted in lowest percent shoot and fruit infestation followed by thiodicarb 375 g a.i. and profenofos 625 g a.i./ha, in both years. It was statistically on par with other insecticides also in their efficacy. The plots treated with Novaluron 37.5 gm a.i./ha resulted in maximum increased fruit yield of 45.00 and 57.67 q/ha over untreated control followed by thiodicarb 375 g a.i. (42.34 & 54.00 q/ha) and profenofos 625 g a.i. (42.00 & 46.67 q/ha). In another experiment Novaluron at different doses showed very little adverse effects on three important predators and parositoids of Brinjal pests infesting the plant in W. Bengal.
