It is evaluated from the study that the higher population of P. gossypiella was harboured on Bt and non Bt cotton hybrid. The population of P. gossypiella larvae was in PKV Hy-2 and RCH-2 BGII was ranging from 0.25 to 1.28 and 0.05 to 0.11, respectively. The lowest mean population of P. gossypiella larvae (0.40) was observed in plant spacing of cotton 120 x 45 cm followed by plant spacing of 90 x 45 cm.
