Abstract: Diapause is one of the primary developmental pathway for insects to escape from unfavorable environment. Knowledge of diapause regulation is essential for rational use of beneficial insects and development of effective pest management strategies. Diapause evokes a unique pattern of gene expression, such as heat shock proteins (Hsps) and acquisition of increased tolerance to environmental stresses. The purpose of this review is to consider the advance on heat shock proteins related to insect diapause, including the relationship between diapause and heat shock proteins, differential expression of heat shock protein gene at different life stages during diapuase and the comparative proteomic analysis between diapause and non-diapause individuals. Unlike other common stress responses that elicit synchronous up-regulation of all Hsps, however, expression of Hsps is different during diapause in different species. The up-regulation of Hsps during diapause is an important factor contributing to overwintering defense strategy and survival. This review may provide some reference to understanding the mechanisms of diapausing insect response to environmental stimuli.
