Abstract

Abstract:

To reduce the economic cost of feeding Tenebrio molitor and improve the utilization of mulberry leaf, different proportions of mulberry leaf powder were added into the feed of Tenebrio molitor, the effects of adding mulberry leaf powder on the growth and development of Tenebrio molitor larvae, and the contents of crude protein, crude fat and water were studied. When the adding proportion was less than 25%, it promoted the weight increasing of Tenebrio molitor larvae and shortened the growth cycle. While when the adding proportion was more than 25%, it inhibited growth and development of Tenebrio molitor larvae. The feeding proportion of mulberry leaf powder of 7.5% increased the weight and crude protein content of Tenebrio molitor larvae significantly, and decreased the content of crude fat. The addition of mulberry leaf powder in the feed did not affect the water content of Tenebrio molitor larvae. Taken together, adding appropriate mulberry leaf powder can improve the growth and development of Tenebrio molitor larvae, and the accumulation of the crude protein, but it is not beneficial to the accumulation of crude fat in Tenebrio molitor larvae.

Key words: Tenebrio molitor, Mulberry Leaf Powder, Feed, Growth and Development, Artificial Feeding
