Biochemical constituents of multivoltine mulberry silkworm (Bombyx mori Linn.) Influenced by Phytojuvenoid compound

The topical application of phytojuvenoid on Bombyx mori larvae has been proved to be of biotechnological significance in the sericulture industry. Total DNA content in the fat body of Bombyx mori larvae at the initial and final stage of spinning was significantly (P1 < 0.01) influenced due to change in the phytojuvenoid concentration. Higher level of the total DNA content was recorded in case of 30% phytojuvenoid concentration – triple treatment of larvae at initial and final stage of spinning. The phytojuvenoid influences the level of DNA in the larvae and caused some beneficial effect on the life pattern of silkworm and the productivity of cocoon.
