Braconid Venom: Biochemical Effects on Immune System in Larvae of a Pyralid Moth.

Effects of the venom gland from the ectoparasitoid Habrobracon hebetor on the prophenoloxidase system of the stored product pest, Plodia interpunctella, were analyzed. Baseline levels of hemolymph phenoloxidase activity in P. interpunctella were established in vitro. These levels were then compared to activity levels of phenoloxidase in the presence of fractionated venom gland components. In addition, a cDNA encoding prophenoloxidase (PPO I) was cloned from a lambda-phage library from whole body P. interpunctella larvae.



Species 1: Lepidoptera Pyralidae Plodia interpunctella (Indian meal moth)
Species 2: Hymenoptera Braconidae Habrobracon hebetor
Keywords: prophenoloxidase, venom
