Abstract: The aim of this study was to investigate the effects of low temperature storage duration and storage density at 5 ℃ on the survival rate, the contents of main biochemical substances and the activities of enzymes in adult Arma chinensis, in order to determine the relationship between the storage duration and the physiological and biochemical responses of A. chinensis. It was found that the survival rate of adult A. chinensis decreased with prolonged storage. The optimal storage density is 100 per box, with a survival rate as high as 91% after 60 days. In response to the low temperature stress, A. chinensis showed a positive response in biochemical substances. The adults accumulated more energy materials such as fat and glycogen, and cold resistant substances such as trehalose, glycerol, triglyceride and sorbitol. At the same time, the activities of trehalase, peroxidase and superoxide dismutase were significantly enhanced. With the extension of storage duration, the content of these substances and enzyme activity gradually decreased or remained unchanged. The results of this study have great significance for the low temperature storage and physiological response mechanism of A. chinensis.
