Cotton is an important fibre crop that historically has experienced serious insect pest problems. Based on this background the present studies were carried out to manage the insect pests on cotton (cv. DHH-543) involving biocontrol agent, botanicals and intercrop. The results shows that intercrop with lucerne (1:1 row proportion), two sprays of NSKE (5%) on cotton at 38 and 60 DAS and release of Chrysoperla carnea (Stephens) grubs @ 0.75 and 1.0 lakhs / ha. starting from 43 DAS redused the sucking pests (leaf hopper, thrips, aphids and white flies) and boll worm, Helicoverpa armigera (Hub.) and increased the seed cotton yield from 5.2 q / ha. in untreated check to 8.40 to 9.00 q / ha. in treated plots. These treatments were on par with insecticidal sprays (Recommended package of practice). The mean H. armigera eggs and larval population was reduced from 1.14 to 0.39 / plant and 0.79 to 0.23 / plant, respectively by the green lacewing (C. carnea) larvae released twice at fortnight intervals @ 0.75 to 1.0 lakh / ha. and yield in the released plot was 8.40 to 9.0 q / ha, respectively.
