Among different hybrids of Bt cotton, Brahma recorded least number of mirid bugs (1.72 bugs/5 squares/plant) followed by VICH 303 (1.80 bugs/5 squares/plant), while non Bt hybrid DCH-32 recorded high incidence of 3.84 bugs/5 squares per plant. Mirid bug incidence was found to be high on genotypes which had higher trichome density, and hence the hairy varieties NCS-145, MRC-7351 and Tulsi-144 might have been prone to mirid attack as compared to glabrous varieties like Brahma, VICH-303 and RCH-530.
