Two insecticides were used to elicit oxidative stress conditions in the firebug Pyrrhocoris apterus, and their ability of adipokinetic hormones (AKHs) to activate protective antioxidative reactions were studied. The insecticide treatments resulted in a significant increase of catalase activity and depletion of the reduced glutathione pool in the haemolymph. Co-application of the insecticides with the AKH (80 pmol) reduced the effect. It has also been found that co-application of the insecticides with AKH increased significantly the bug mortality. This enhanced effect of the insecticides probably resulted from the stimulatory role of AKH on bug metabolism. It was hypothesized that the increased metabolic rate could intensify the insecticide action by faster penetration of insecticides into tissues.
