The study on “Incidence of sucking pests and natural enemies in cotton under high density planting system (HDPS)” was conducted at RARS, Lam, Guntur during kharif, 2016-17 to observe the incidence of sucking pests such as leafhoppers, aphids, thrips and whitefly and also the incidence of natural enemies (Spiders and Coccinellids). Among the sucking pests thrips population was found dominating other sucking pests during initial days of crop growth period i.e., up to 90 DAS there after aphid population was dominated i.e., from 90-135 DAS both in normal and HDPS. Leafhopper and whitefly population did not show any significant difference between both normal and HDPS. Leafhopper population crossed ETL only at 45 and 75 DAS but whitefly population did not cross the ETL throughout crop growth period. Spider population was coincided with the incidence of aphid population during 90-135 DAS.
