Tissue specific glucose-trehalose variations during spinning in the eri-silkworm, (Philosamia ricini).

The beginning of spinning process in Eri-silkworm is characterized by sharp fall in the levels of glucose and trehalose in silkgland which gets completely decomposed after 6 days of spinning. Fatbody actively synthesizes trehalose during early days of spinning which results in enhanced level of this disaccharide in haemolymph. On the other hand, decreased glucose concentration of body fluid during early days of spinning is apparently because of its absorption by silkgland for its energetic needs.
