APPLICATION OF PHYTOJUVENOID ENHANCES THE AMINO ACIDS IN THE MULTIVOLTINE MULBERRY SILKWORM (BOMBYX MORI LINN.)

ABSTRACT Impact of phytojuvenoid on total free amino acids content in the haemolymph in Bombyx mori, a monophagous insect, was studied. Total free amino acids content in the haemolymph of Bombyx mori larvae at the initial and final stage of spinning increased with the increasing number of larval treatment in 10, 20 and 30% phytojuvenoid concentration which reached to the maximum level of 34.64 ± 0.05 µg/mg in the initial and 11.70 µg/mg in the final stage of spinning while in 40% phytojuvenoid concentration the total free amino acids content increased in single treatment of larvae but further increase in the number of larval treatment caused considerable decline. The results show that topical application of bioactive phytojuvenoid improved the commercial parameters in Bombyx mori
