The effect of intercropping in cotton on the population of aphids, leafhoppers and bollworms and their natural enemies was investigated. Intercropping did not show any variations on the pest population of aphids and leafhoppers. Significantly increased activity of coccinellids in cotton inter-cropped with cowpea was observed. Higher parasitism on Earias spp. was recorded in cowpea and soybean intercropped cotton as compared to onion and pure cotton.
