Climate change is reshaping the ecological balance between crops, insect pests, and their natural enemies, thereby creating new challenges for global food security. Rising global temperatures, altered precipitation patterns, and shifting seasonal cycles are driving changes in insect behavior, distribution, and life cycle, intensifying challenges in crop production. Warmer climates enable pests to expand their geographic range, enhance overwintering survival, increase the risk of invasive insect pest species and insect-vectored plant diseases, and shift their interaction with host plants and natural enemies. Simultaneously, elevated CO2 levels may alter host plant physiology, influence pest–plant interactions, and reduce the effects of natural predators. These changes threaten not only yield stability but also the efficacy of existing pest management strategies. Agricultural resilience involves encountering climate-driven insect population growth through adaptive pest management. Sustainable practices ensure protection against expanded pest ranges and increase disease risks.
