A field experiment was carried out to investigate the seasonal incidence and influence under unprotected conditions of abiotic factors on infestation of shoot and fruit borer (Leucinodes orbonalis Guenee) in brinjal during Kharif 2013-14 and 2014-15 of Varanasi region. The results revealed that the incidence of shoot and fruit borer and shoot infestation started from first week of August whereas, fruit infestation started from third week of September during both the years. The highest per cent shoot infestation was recorded in second week of September during both the years and the highest per cent fruit infestation of shoot and fruit borer was recorded on third week of October during both years. The shoot and fruit borer was active throughout the cropping season. Among the weather parameters, maximum temperature, minimum temperature, morning relative humidity and sunshine hours showed positive correlation but with rainfall and evening relative humidity showed negative correlation on the incidence of both shoot and fruit infestation by the pest. Thus the management of brinjal shoot and fruit borer during Kharif sown brinjal should therefore be initiated from August onwards using an integrated approach.
