Isolation and characterization of bacteria-induced protein P4 from hemolymph of Manduca sexta.

abstract：:Honey bees Apis mellifera L. are one of the most studied insect species due to their economic importance. The interest in studying honey bees chiefly stems from the recent rapid decrease in their world population, which has become a problem of food security. Nevertheless, there are no systemic studies on the propertie...
