Population dynamics studies on sucking insect pests viz., whitefly (Bemisia tabaci), jassid (Empoasca kerri) and thrips (Caliothrips indicus) of mungbean [Vigna radiata (L.) Wilczek] were carried out at Genetics and Plant Breeding Research Farm of Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya (UP), India during Kharif 2017. The weekly observation of sucking insect pests of mungbean recorded from 20 days after sowing till harvest. Population of whitefly and jassid were observed from 36^th SW and continued up to 42^nd SW. The maximum and minimum population of whitefly was recorded in 41^st SW (4.9 whitefly/cage) and 36^th SW (3.6 whitefly/cage), respectively. The overall population of jassid ranged from 3.6 (42^nd SW) to 4.7 (39^th SW) jassid/cage. The thrips population recorded from 38^th SW to 42^nd SW and had highest population of 1.2 thrips/5 plants during 41^st SW. Lowest population of thrips was recorded in 38^th SW (1.1 thrips/5 plants).
