The effect of Pyrap-AKH on the mortality of the firebug Pyrrhocoris apterus treated by the insecticide permethrin was studied. Co-injection of permethrin with Pyrap-AKH induced a significant increase in the bug mortality compared to the insecticide alone. The results were confirmed also by topical co-application of both agents. Injections of permethrin elicited also significant increase of the AKH level in the body. The results indicate an involvement of AKH in stress response to permethrin. The enhanced effect of insecticide by AKH treatments probably results from the stimulatory role on bug metabolism: the carbon dioxide production was increased after the permethrin treatment, and after the permethrin plus AKH co-treatment, compared to control. The elevation of metabolism could intensify the permethrin action by its faster penetration into tissues and by stimulation of biochemically active cells.
