AN OVERVIEW ON SUITABILITY OF ECO-FRIENDLY IPM APPROACH FOR MANAGEMENT OF BT-RESISTANCE IN PINK BOLLWORM ON COTTON

Abstract

Pink Bollworm (Pectinophora gossypiella) member of the family Gelechiidae is known to be among the most destructive insect pest of cotton, causing huge damage to the cotton seed as well as heavy loss in fiber quality of the crop. Its larvae are active feeder of the reproductive parts of cotton and conceal in the damaged bolls. Large scale cultivation of transgenic cotton that produces Cry1Ac resulted in development of resistance in pink bollworm against Cry1Ac. A single control tactic even chemical control remains ineffective for their management and all possible tactics are integrated for their effective control. For its monitoring Sex pheromone traps, PB Ropes and light traps are installed. Growing of non Bt refugia also play an effective role for the management of pink bollworm. Keeping in view, the importance of Integrated Pest Management (IPM) is an ecofriendly and effective technique as compared with the use of conventional insecticidal technique.
