Abstract: In order to understand the physiological adaptability of Tenebrio molitor larvae to different food proportions, the effects of five different food comparisons on the growth characteristics and the activities of digestive enzymes and protective enzymes in Tenebrio molitor larvae were determined. The results showed that different food comparisons had a significant effect on the development, digestive enzyme and protective enzyme activities of T. molitor larvae. Adding green fodder with high water content in wheat bran, especially high sugar content of apples, pears and other fruits were conducive to promoting the growth of T. molitor larvae. There was a positive correlation between the development and the protease activity of T. molitor larvae in different food proportions. The growth rate of the larvae of T. molitor was not correlated with the activity of protective enzymes, but the activity of SOD and CAT was the lowest in the larvae with the fastest growth of the treatment 5(83% wheat bran with 17% pear).

Key words: Tenebrio molitor larvae, food proportions, development, digestive enzyme, protective enzyme
