Bt cotton has revolutionized pest management in cotton cultivation by providing an effective means of controlling major pests, such as the pink bollworm and cotton bollworm. However, the widespread adoption of Bt cotton has also led to the emergence of resistance in target pests, threatening its long-term efficacy. This study explores the development of resistance in cotton pests, the factors contributing to this challenge, and the current strategies implemented to manage resistance, such as refuge strategies and integrated pest management (IPM). A specific case study is presented, detailing the successful application of resistance management techniques in a Bt cotton-growing region. This study also discusses recent advancements in genetic and biotechnological approaches aimed at enhancing Bt cotton’s efficacy and addressing resistance issues. It concludes with future perspectives, emphasizing the need for collaborative efforts, continuous monitoring, and the development of policies to sustain the benefits of Bt cotton in global cotton production.
