Abstract The study conducted at Regional Agricultural Research station, Lam, Guntur, Andhra Pradesh in greengram for three consecutive years during 2019, 2020 and 2021 using three commercially available double sided yellow, blue, and white sticky traps placed at 0, 1, 2, 3, 4, 5 ft height from the crop canopy in bulk crop showed that blue sticky traps were more attractive to thrips, yellow sticky traps for whiteflies and leafminers. while, the yellow sticky traps were found detrimental to coccinellids. The trapping of insects reduced with the increase in trap height from the crop canopy irrespective of the trap colour. The traps placed upto 2 ft above the crop canopy recorded higher number of sucking pests as well as coccinellids in greengram. Top Keywords Sticky traps, Trap height, Whiteflies, Thrips, Greengram.
