Can Feeding of Silkworm on Different Mulberry Variety Affect Its Performance?

This study attempted to identify a suitable host plant for rearing hybrid 31*32 silkworms. Four varieties of mulberry leaves including Ichinose, Kenmochi, Kines, and local were supplied to hybrid 31*32 of silkworm and their performance was assessed. Variables measured included nutrition, biochemistry, and economic parameters of silkworm. Number of cocoons, individual and total cocoon weight, cocoon shell weight, and cocoon yield/10,000 per larvae were significantly greater on the Kines variety compared with the others. Similarly, nutritional indices including efficiency of conversion of ingested food (ECI), efficiency of conversion of digested food (ECD), relative growth rate (RGR), and consumption index (CI) were greater for the larvae fed on Kines. Digestive and antioxidant enzyme activity of the larvae differed with variety. Our results suggest that Kines could be considered as an appropriate host plant for rearing of silkworms based on the study parameters.
