Pesticide resistance in insects is a growing challenge that threatens the sustainability of modern agricultural practices. This resistance, which arises from genetic adaptations within pest populations, reduces the effectiveness of chemical controls and necessitates higher doses or alternative, often more toxic, pesticides. The rise in resistance has profound implications for crop yields, economic costs, environmental health, and human safety. This paper investigates the underlying mechanisms of insect pesticide resistance, including genetic mutations, selection pressures, and cross-resistance. It also explores the broad-spectrum impacts of resistance, such as disruptions to ecological balance, harm to beneficial organisms, and increased pesticide residues in the environment. To address these challenges, the paper advocates for a shift towards integrated pest management (IPM) strategies, which combine chemical, biological, and cultural controls. Emphasis is placed on practices such as rotation of active ingredients, use of resistant crop varieties, and the promotion of natural pest predators. By adopting these sustainable solutions, agriculture can mitigate the adverse effects of resistance, reduce reliance on chemical pesticides, and promote long-term ecological and economic resilience.
