abstract
The present study was aimed at investigate the economic parameter of the silkworm cocoon. The topical application of phytojuvenoid on Bombyx mori larvae has been proved to be of biotechnological significance in the sericulture industry. Maximum denier of cocoon was recorded to be 1.98 d. in case of 30% phytojuvenoid concentration – triple treated larvae while it was minimum 1.23 d. in 40% phytojuvenoid concentration at triple treated larvae. The outcome of this work is expected to have applied significance and the knowledge derived from the present study will be helpful in the rearing of silkworm on industrial scale and generate more employment opportunities.
