Laboratory experiment was conducted during Kharif 2017-18 at Department of Entomology, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani (Maharashtra) to study biology of Leucinodes orbonalis Guenee on Brinjal under laboratory condition. The results revealed that the oviposition, incubation, larval, pupal and total developmental period were 3.20±0.79, 3.40±0.97, 15.35±1.16, 6.90±1.37 and 25.65±2.75 days respectively, In the present study, the average longevity of female moth and male moth were 6.4±1.35 and 4.1±1.20 days respectively. The mean number of eggs laid by female moth of shoot and fruit borer were 93.40±6.50 eggs. The sex ratio (F/M) of emerged adults of L. orbonalis after feeding on hosts i.e. brinjal was found 1.94:1 while the mean duration of mating i.e. coitus was 20.08 ± 2.94 minutes.
