The study on the biology of shoot and fruit borer wascarried out in the Research Laboratory of Department of Entomology, College of Agriculture, R.V.S.K.V.V., Gwalior (M.P.) India, Kharif during 2018-19. White creamy eggs were laid single in bunches which were oval to elongate in shape. The incubation period of the brinjal shoot and fruit borer on brinjal food varied from 4-6 days with a mean duration of 4.95 ± 0.60 days. Whitish to dark pinkish larva period through instar to became full grown the average larval period varied from 10 to 13 days with a mean duration of 11.25 ± 0.95 days in brinjal food part. under laboratory condition. Pinkish to dark brown pupa took place an average of 7.18 ± 0.74days and pupal period varied from 6 to 8days become an adult. The adult moths were small in size with whitish wings the adult longevity varies from 4.0 to 5.5 days during experiment, with an averageof 4.92 ± 0.54days thus, the total life cycle completed period from 24 to 29 days with a mean duration of 27.08 ± 1.52 days in brinjal food. The male and female ratio varied from 1 to 2during experiment, with an average ratio of 1:2under laboratory conditions.
