Haemolymph protein estimation in six different strains of Eri silk worm, Samia ricini (Donovan)

Abstract

The present study was conducted to evaluate the haemolymph protein in six different Eri silk worm strains in their 5th instar- in the middle of the instar and at ripening or just before pupation. The result showed that in all the strains the concentration of protein was found highest at ripening when the worm is fully matured. Significant differences were found in protein level in two different study period of fifth instar larva in all six strains. Among all the strains Yellow Spotted (YS) was reported to have highest haemolymph protein concentration followed by Yellow Plain (YP). The protein concentration in ascending order was –GBZ
