Biotechnological importance of topical application of phytojuvenoid with particular reference to biochemical performance of multivoltine mulberry silkworm (Bombyx mori Linn.)

ABSTRACT

The topical application of phytojuvenoid on Bombyx mori larvae has been proved to be of biotechnological significance in the sericulture industry. Variation in the phytojuvenoid concentration significantly (P₁<0.01) influenced the total protein level in the fat body of larvae at the initial stage of spinning. The maximum level of total   protein content was recorded in case of 30% phytojuvenoid concentration at triple treated(III^th - IV^th) larvae while it was lowest in 40% phytojuvenoid concentration at triple treated larvae at the initial stage of spinning. The phytojuvenoid influences the level of protein in the larvae and caused some beneficial effect on the life pattern of silkworm and the productivity of cocoon.

Key words: Phytojuvenoid, Protein content, Fat body, Larvae, Bombyx mori.
