Abstract: In order to enhance the effect of Dastarcus helophoroides on prophylaxis and treatment of walnut Batocera horsfieldi,used walnut leaf,which is host plant of B. horsfieldi,to artificially feed Tenebrio molitor larvae that substitutes original host D. helophoroides,the suitability of walnut leaf as fodder through the determination of growth of T. molitor larvae was evaluated. The results indicated that walnut leaf fodder had obvious effects on digestive enzyme activity in T. molitor larvae and growth condition. Adding unfermented walnut leaf to wheat bran fodder can inhibit the growth of T. molitor larvae. Instead,wheat bran fodder with fermented walnut leaf showed increasing trend of T. molitor larvae,of whom the growing speed was fastest under treatment 50% wheat bran plus 50% fermented walnut leaf. Growing amount of T. molitor larvae was correlated with internal protease activity,but no correlation with amylase and saccharase activity.

Key words: Tenebrio molitor larvae, walnut leaf, fermentation, development, digestive enzy
