Succession and Incidence of Insect Pest on Green gram (Vigna radiata L. Wilzek) during Summer Season

Seasonal incidence of insect pests infesting green gram, variety Pusa Vishal was sown on 10 X 10 m plot at the Experimental Field of Department of Plant Breeding and Genetics, JNKVV. Jabalpur (M.P.) during summer season. The incidence of whitefly (Bemisia tabaci Gennadius), jassid (Empoasca kerri), thrips (Taeniothrips sp.) was started from 15^th standard week and continued up to22^nd standard week with peak population recorded in 20^th standard week. Significant positive correlation was observed with maximum temperature and jassid population and negative correlation between morning relative humidity with jassid and whitefly population and morning vapour pressure with whitefly population.
