Abstract: Silkworm Bombyx mori is an important economic insect and also a tool to convert leaf protein into silk protein. This study was carried out to determine the feed efficacy of silkworm Bombyx mori fed by mulberry (Morus sinensis) leaves and different concentrations of silver nanoparticles treated mulberry (Morus sinensis) leaves in relation to physiological parameters like food consumption (FC), and Economical traits. Biogenic synthesis of silver nanoparticles by using two white rot fungi. The different concentrations (25%, 50%, 75% and 100%) of prepared silver nanoparticles were treated to the larval period. In the present study, it has been observed that the treatment of AgNps at the concentration of G-1 at 50%, GK-14 at 75% may have beneficial effects on the increase of the silkworm larval and pupal length, width, weight and quantity of silk production by enriching the feed effectiveness than control. This study has been indicated that the Silver nanoparticles exhibit the presence of certain growth stimulant activity and can be used to increase the silk yield in commercial silkworm rearing with reference to Sericulture.
