Field experiments on screening of twenty nine chilli germplasm against yellow mite and thrips damage was conducted during rabi seasons of 2012-13 and 2013-14 at Kalyani ‘C’ Block Farm, BCKV, West Bengal. The results on the basis of percent of plant showing visible symptoms revealed that hybrids like 2012/CHYB-11 (15.96%), 2011/CHYB-4 (16.60%), 2013/CHYB-1 (17.60%) and 2012/CHYB-5 (18.00%) were found field tolerant to yellow mite whereas BSS-453 (21.38%), 2011/CHYB-3 (22.53%) and 2012/CHYB-3 (23.54%) were found most moderately field tolerant. The hybrids BSS-453 (18.41%), 2012/CHYB-5 (19.06%) and 2013/CHYB-1(19.46%) were identified as field tolerant to thrips whereas 2012/CHYB-11 (21.59%), 2013/CHYB-4 (22.37%) and 2011/CHYB-4 (22.85%) were recorded as mostly moderately tolerant. The most susceptible hybrid to yellow mite recorded was 2011/CHYB-8 (38.60%) whereas for thrips was 2012/CHYB-10 (37.26%). Chilli hybrid lines 2013/CHYB-1 and 2012/CHYB-5 were found less affected or tolerant against both mites and thrips and could be exploited in the resistance breeding programme.
