Mechanisms and implications of diapause and seasonal adaptation in insects

Abstract

Diapause and seasonal adaptation are vital strategies that enable insects to survive adverse environmental conditions, ensuring their persistence across diverse ecosystems. This review explores the mechanisms of diapause, including hormonal control, metabolic changes, and genetic regulation, which collectively allow insects to pause development during unfavourable seasons. The ecological implications are significant, as these adaptations influence insect population dynamics, species distribution and ecosystem interactions. In pest management, understanding diapause offers practical applications, such as predicting pest emergence and optimizing control measures. By targeting diapause mechanisms, novel strategies could be developed to manage pest populations more effectively, reducing the need for chemical interventions. The review concludes that while diapause is a well-established adaptation, climate change poses new challenges by potentially disrupting these finely tuned processes. Continued research is essential to unravel the complexities of diapause and to apply this knowledge in both agricultural practices and conservation efforts.
