Última Activation of Prophenoloxidase and Removal of Bacillus subtilis from the Hemolymph of Acheta domesticus (L.) (Orthoptera: Gryllidae) Neotropical Entomology SILVA,CLEONOR C.A. DA. Insect phenoloxidase is considered an important mediator in defense reaction against pathogens and parasites. It is present in the hemolymph of most insects as an inactive proenzyme, called prophenoloxidase. In Acheta domesticus (L.) the phenoloxidase activity was studied in the presence of Bacillus subtilis. The bacteria induced the activation of the prophenoloxidase and increased the level of phenoloxidase activity when injected into the hemocoel of A. domesticus nymphs. The level of increase was comparable to those observed in nymphs injected with laminarin, an activator of the proenzyme. Incubating B. subtilis in serum with phenoloxidase activated in vitro and then injecting into the insects accelerated the removal of the bacteria from the hemolymph in...
