Abstract: Insects are one of the most biodiversity-rich ecological groups in the organic sphere. In order to resist to adverse environment, complete life history and survive from the long process of adaptation, insects have evolved a series of strategies to improve the ability of cold resistance and the ability of withstanding low temperature changes. For better understanding the specific characters of cold-resistance ability of insects, this paper reviewed research progresses in the following aspects: overwintering stages, overwintering behavior, as well as physiological and biochemical mechanisms of cold tolerance. Detail strategies were also discussed, such as moisture content adjusting, ice nucleator in the body, metabolic pathways changing, antifreeze small molecular substances accumulating, antifreeze proteins producing and antifreeze material system establishing. Previous studies were summarized, basis information was provided for the future studies of insect coldresistance.
