Relative performance of Trichogramma chilonis, chemical insecticides and botanicals against brinjal shoot and fruit borer, Leucinodes orbonalis Guen.

The field investigation was carried out in the Insectary and at the Field of Entomology Section, College of Agriculture, Nagpur during the kharif season of 2024-25. The experiment was carried out in Randomized Block Design (RBD) with seven treatments and three replications. Treatments were applied at 10 days interval. The fruit infestation ranged from (12.34 to 29.01%) in various treatments on weight basis. The results revealed that the treatments (T2) Two release of Trichogramma chilonis @ 1.00 lakh/ha followed by spraying alternatively of Emamectin Benzoate 5 SG @ 0.4 g/l and Spinosad 45 SC @ 0.5 ml/l and (T4) Emamectin Benzoate 5 SG @ 0.4 g/l followed by Spinosad 45 SC @ 0.5 ml/l were superior to all other treatments and statistically at par with each other, wherein 12.34 and 13.14 percent fruit infestation recorded with 57.46 and 54.71 percent reduction over control respectively. However, the next effective treatments were observed (T4) Emamectin Benzoate 5 SG @ 0.4 g/l followed by Spinosad 45 SC @ 0.5 ml/l and (T1) Release of Trichogramma chilonis @ 1.00 lakh/ha which were at par with each other and recorded 13.14 and 14.05 percent fruit infestation with 54.71 and 51.57 percent reduction over control respectively, on weight basis as compared to control (29.01%) against brinjal shoot and fruit borer Leucinodes orbonalis.
