A selective method of application of insecticide viz, 'Skip row coverage' has been employed against sucking pests in cotton. Skip row coverage with monocrotrophos (as alternate row or as alternate pair row) was as effective as full coverage against the leafhopper, Amrasca biguttula biguttula Ishida and the aphid, Aphis gossypii Glov. Deltamethrin, endosulfan and monocrotophos as skip row spray coverage harboured more population of the predator, Chrysoperla carnea (Steph), while monocrotophos, carbaryl and deltamethrin spared the predator, Menochilus sexmaculata (Fab.) by 2 .0 to 2.4, 1.6 to 2.2 and 1.2 to 2.8 times more than full coverage with the respective insecticides.Keywords
