Abstract:

The cold acclimation can improve the cold tolerance of insect significantly. This article reviewed the methods of insect cold acclimation and the biological indicators for cold tolerance, the biotic factors (insect development stage, gender and diapause) and abiotic factors (temperature, photoperiod, humidity, etc.) that affect the cold acclimation of insect were analyzed. Then, the impact of cold acclimation on insect in terms of growth and development, reproductive capacity and offspring was clarified. Furthermore, the mechanism of improving insect cold tolerance through cold acclimation was explored from the perspectives of cold resistance related proteins and metabolic regulation. It is expected to provide reference for the deep study of cold acclimation and cold storage techniques of insects, in order to promote the utilization of natural enemies and pest control.

Key words: cold acclimation, cold hardness, supercooling point, influence factor, fitness, mechanism
