incidence of pest complex in three cultivars viz., in MECH 162 Bt, MECH 162 non-Bt and Brahma cotton cultivars. The treatments were replicated nine times in randomized block design. The incidence of leafhopper, aphid and whitefly was found in all the three cultivars throughout the crop season, but the cotton bollworm, Helicoverpa armigera and spotted bollworm, Earias vitella infestation was comparatively less in MECH 162 Bt cotton than other cultivars. The maximum incidence of H. armigera was recorded during 14th and 15th weeks after sowing in all the three cultivars.
