![]() Based on current knowledge, despite common threads, molecular mechanisms of winter survival vary considerably across species, and taxonomic biases must be addressed to fully appreciate the mechanistic basis of winter survival across the insect phylogeny.Įxpected final online publication date for the Annual Review of Entomology, Volume 68 is January 2023. In addition, we highlight mechanisms that are subject to selection as insects evolve to variable winter conditions. Molecular responses to low temperature are also dynamic and include signaling events during and after a cold stressor to prevent and repair cold injury.

Anticipatory processes such as cold acclimation and diapause cause wholesale transcriptional reorganization that increases cold resistance and promotes cryoprotectant production and energy storage. In this review, we summarize molecular processes associated with winter survival, with a particular focus on coping with cold injury and energetic challenges. As a result, the geographic distribution of many species is tightly coupled to their ability to survive winter. Winter provides many challenges for insects, including direct injury to tissues and energy drain due to low food availability.
