The present investigation on seasonal incidence of insect pests of brinjal were carried out at entomology research field, Institute of Agriculture and Natural Science, (Diksha Bhavan) Deen Dayal Upadhyaya Gorakhpur university Gorakhpur (Uttar Pradesh) during Rabi-2022-23. The first appearance of aphid in 46th SMW, whitefly in 47th SMW and jassid in 48th SMW was recorded. Aphid population was recorded maximum during 7th SMW whitefly in 8th SMW and jassid in 9th SMW. Aphid population showed negatively non-significant correlation with the min. temperature, max. temperature and rainfall whereas positively non-significant correlation with the relative humidity morning and relative humidity evening. The whitefly and jassid population showed positively non-significant correlation with the min. temperature and max. temperature and non-significant correlation with morning relative humidity, evening relative humidity and rainfall. This work tackles the problem of knowing the complicated dynamics of insect infestations in eggplant agriculture. Sucking insect pests such as aphids, whiteflies, and jassids threaten crop health and productivity by sucking sap from plants. This is a difficult task since we must determine when these bugs will appear, how much damage they will inflict, and how to stop them without damaging the ecosystem.

The present investigation has concluded that the sucking pests (aphid, jassid, whitefly). Aphid and whitefly population was recorded maximum during 7th SMW and jassid in 9th SMW. Aphid population showed negatively non-significant correlation with the minimum temperature, maximum temperature and rainfall while positively non-significant correlation with the relative humidity morning and relative humidity evening. The whitefly and jassid population showed positively non-significant correlation with the maximum and minimum temperature and non-significant correlation with morning relative humidity, evening relative humidity and rainfall.
