The freshly collected mulberry leaves were smeared with solutions of nanoparticles of riboflavin a vitamin (B2) in different concentrations. The enriched leaves were air dried. The fifth instar larvae of mulberry silkworm Bombyx mori L. were fed with enriched leaves thrice a day. Feeding parameters,Food conversion efficiency, growth and economic characters were studied and recorded. Supplementation of nanoparticles of vitamin B2 showed a positive impact and significantly enhanced the growth of the larvae (28.985%), silk gland weight (111.392%) and silk yield (194.44%) when compared to control. So vitamin B2 nanoparticles can be used as a fortification agent for improving the silk production.
