The silkworms are monophagous insect which feeds only on mulberry leaves. It takes necessary nutrients for growth and development only from the mulberry leaves. The nutritive value of mulberry depends on many factors. The biomolecules like carbohydrates and protein play a major role in its growth, development and silk productivity. Enzymes along with other factors like hormones have a crucial role in the growth and metamorphosis of silkworm. The availability of biomolecules as nutrients has an important role in conversion efficiency of it to silk by silkworm. The plant parameters were found to be better in Suvarna3 and Vishala mulberry variety among the varieties studied. Biochemical work was carried out for that different variety of mulberry to check the nutrition value of that leaves. The IMH × CSR2 (Bangalore Belli) improved crossbreed (ICB) silkworm larvae were fed with different varieties of mulberry leaves. Finally, the economic parameters of cocoons fed on different mulberry varieties were analyzed. The present study depicts Suvarna3 and Vishala has a better performance among the mulberry varieties studied.
