| Abstract: | Several aspects of immune response in insects treated with an organophosphate (pirimiphosmethyl) have been assessed. Both humoral (phenoloxidase activity) and cellular (hemocyte count and encapsulation rate) immunity changes have been studied in larvae of the representatives of two insect orders, the Colorado potato beetle Leptinotarsa decemlineata (Coleoptera, Chrysomelidae) and the wax moth Galleria mellonella (Lepidoptera, Pyralidae). A direct contact with sublethal and half-lethal doses of the insecticide results in stimulation of immune reactions: phenoloxidase activity and encapsulation rate are heightened, and hemocyte count increases. |
