A bulk plot of 100 m2 was raised duly following the recommended agronomic practices to study the population buildup of sucking pest complex in black gram during Rabi 207-18 at Students farm, College of agriculture, Rajendranagar, Hyderabad. Sucking pests like leafhoppers, whiteflies and thrips were recorded during the entire crop period. Incidence of aphids in black gram during the entire crop season did not occur. The results indicated that the population of sucking pest in Rabi black gram were started from 2nd week after sowing with 1.80, 2.00 and 2.40 leafhoppers, whiteflies and thrips per six leaves respectively and their population were high during the vegetative stages and reached its peak during the reproductive stage with 6.80, 6.90 and 8.10 leafhoppers, whiteflies and thrips per six leaves respectively and later declined to a population of 1.20, 2.20 and 2.20 leafhoppers, whiteflies and thrips per six leaves respectively
