Pink Bollworm management in cotton: Challenges, innovations, and sustainable solutions

Abstract

Pink bollworm (Pectinophora gossypiella) poses a significant threat to cotton production worldwide. Despite the initial success of Bt cotton, resistance has emerged, necessitating alternative management strategies. Integrated Pest Management (IPM) approaches, including mating disruption and the sterile insect technique (SIT), offer promising solutions. The SPLAT (Specialized Pheromone and Lure Application Technology) technique utilizes wax-based formulations to disrupt pink bollworm mating behaviour, reducing population growth and damage to cotton crops. Meanwhile, SIT utilizes radiation to induce sterility in pink bollworm populations, reducing reproductive rates and mitigating infestation levels. Embracing these innovative strategies collectively ensures sustainable cotton cultivation, safeguarding farmers' livelihoods and reinforcing resilience against the persistent threat of the pink bollworm.
