The result raveled that thrips population was recorded least imposition in dinotefuran 20 SG @ 0.3g/ l (8.69 thrips/ 3 leaves), thiamethoxam 25 WG @ 0.25g/ l (4.81 thrips/ 3 leaves) and imidacloprid 17.8 SL @ 0.25 ml/ l (2.59 thrips/ 3 leaves) were most effective treatments in reducing incidence of thrips on Bt cotton as compared to other chemicals. However, in leafhoppers population significantly lowest number of leafhoppers was recorded in thiamethoxam 25 WG @ 0.25 g/ l (4.30 leafhoppers/ 3 leaves), imidacloprid 17.8 SL @ 0.25 ml/ l (3.64 leafhoppers/ 3 leaves) and imidacloprid 70 WG @ 0.25g/ l (2.43 leafhoppers/ 3 leaves) were effective chemical against cotton leaf hopper compared to other chemicals.
