A field experiment was carried out for the management of pink bollworm in Bt Cotton using different modules 2019-20 at Cotton Research Station, Vehari, Pakistan. During Kharif 2019 and 2020. Among different modules, the lowest number of pink bollworm (PBW) larvae (32.5/25 green bolls) and locule damage (71/100 fully opened bolls) was noticed in the chemical control module followed by biological control module (47 larvae/25 green bolls; 102 damaged locules/100 fully opened bolls) and biological + chemical control module (52.5 larvae/25 green bolls; 105.5 damaged locules/100 fully opened bolls). The highest number of PBW larvae (67 /25green bolls) and locule damage (130.5 damaged locules/100 fully opened bolls) was observed in the untreated control module. Overall, the highest benefit-cost ratio was recorded in the chemical control module as compared to other modules. From this study, it is concluded that for management of PBW insecticidal sprays at ETLs proved better than biological control and other methods.
