Abstract:

The current paper introduces the recent research and development on the cryobiology of ticks， based on their overwinter behavior strategy and biochemical and physiological adaptation mechanisms， and provides detail information on the cold hardiness， biochemical and physiological mechanisms， the relationship between cold hardiness and diapause， which will give theoretical clues for subsequent research on the molecular regulation of cold hardiness of ticks.

Key words: Tick, Cold hardiness, Overwinter, Diapause
