Twenty five genotypes of cotton viz, MNH-2007, CIM-588, FH-942, PB-900, NN-3, CIM-573, BH-173, NIAB-852, NIAB-2009, CIM-473, BH-172, FH-941, MNH-886, N-2008, FH-113/1000/P7, FH-113/126, CIM-496, FH-2015, VH-289, CIM-552, VH-280, MNH-814, SLH-317, RH-625 and FH-4243 were tested for resistance against insect pests: whitefly (Bemisia tabaci Genn.), Jassid (Amrasca devastans Dist.), Thrips (Thrips tabaci Linn.), Spotted bollworm (Earias spp.), and Cotton leaf curl virus (CLCV) cin field conditions during 2012 and 2013. Out of twenty five cultivars MNH-2007 and CIM-588 were found comparatively resistant, showing minimum average population of white-fly (3.26 & 3.43 /leaf), FH-941 and PB-900 against Jassid (1.54 & 1.47 /leaf), VH-280 and FH-942 against Thrips (6.46 & 6.59/ leaf). FH-113/126 and PB-900 showed minimum bolls infestation by Spotted Bollworm (1.05 & 1.87%).rnVH-289 and VH-280 exhibited minimum CLCV incidence (2.83% & 3.0%) respectively. Maximum average population of whitefly was found on cultivars FH-4243 and RH-625 (4.75 & 4.72/leaf), cultivars BH-172 and MNH-814 against Jassid (10.90 & 2.61/leaf), MNH-814 and NIAB-852 against thrips (10.44 & 10.18/leaf) respectively. NIAB-852 and VH-280 showed maximum bolls infestation by Spotted Bollworm (10.56 & 8.51%), FH-942 and MNH-886 exhibited maximum CLCV incidence (78.67% & 73.67%) respectively during 2012.
