Tenebrio molitor pupae stored at 9,3,-3 and-9 ℃ for 5,15,25,35 and 45 d respectively,the pupae content of protein,total sugar,trehalose,glycogen,polysaccharide and fat were measured.Results indicated storage temperature and time had significant influence on the nutrition content of the pupae.The content of protein,total sugar,trehalose,glycogen and fat decreased gradually along with the time,but the decline rate speed was different among them.Total sugar,trehalose and glycogen were exhausted more under higher temperature than lower temperature.While,the protein and fat only expeditiously reduced from3 to 9 ℃.And the data of protein and fat at-9 ℃ was lower than-3 ℃ at preservation time.It had opposite trend for polysaccharide content to the above mentioned nutrition.It was increased with adding preservation temperature and time combines,and the most value could be to four times than before.
