摘要：The pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae) is an important insect pest of the cotton crop worldwide. Sex-pheromone and light traps were used to monitor the adult P. gossypiella population in Bt cotton ﬁeld for the years 2017-18 at southern Punjab, Pakistan. The sampling of infested bolls was done to record the damage level of P. gossypiella. The sex-pheromone traps captured approximately 2-3 times more adults than light traps in all locations during 2017-18. For sex-pheromone traps, temperature showed negative and strong relation (R2 = 0.63-0.80) with trap catches. Fewer bolls (7.0-9.0%) were infested in plots where sex-pheromone traps were installed compared to check plots (32-37%). Therefore, the pheromone trapping proved an effective and eco-friendly tool for the monitoring and management of P. gossypiella. Our findings enable forecasting of seasonal P. gossypiella population providing additional information for the development of an integrated pest management program for this pest.
