Mating and Oviposition Behaviour of Brinjal Shoot And Fruit Borer, Leucinodes Orbonalis Guenee

Mating and oviposition behaviour of brinjal shoot fruit borer (BSFB), Leucinodes orbonalis Guenee (Lepidoptera:Pyralidae) were carried out in the laboratory on plants maintaining temperature (20-250C) relative humidity (80-85%). The moths found active at night for mating oviposition. usually occurred late but a few to continue up 8.0 hour day. Maximum completed between 4.00 6.00 period ranged from 28-50 minutes. first second adult emergence. Majority (90.80%) mate rest went following night.
