Abstract：To study the changes of immunity activity after the hemopoietic organs damaged, silkworm larvae were radiosurgery with carbon ion beams, each us the change of body weight in 5th instar, phenolxidase activity in hemolymph and the quantity of induced bacterial challenge-related proteins were investigated. The results showed: after the hemopoietic organs being damaged, the activity of phenolxidase was down, the quantity of bacterial challenge-related proteins induced by E. coli significantly decreased and the survival rate of larvae fed with Bacillus thuringiensis dropped obviously, the body weight of larvae fed with mulberry leaves hardly decreased, while for larvae fed with commercial artificial diet, the body weight increased and almost had no significant different with that of control’s. It is considerated: after the hemopoietic organs of silkworm being destroyed, they dropped body immune activity; raise by no bacteria condition can meliorate the effect caused by the hemopoietic organs functional obstacle.
