Methoprene modifies adipokinetic hormone characteristics in the firebug Pyrrhoceris apterus (Heteropeta: Pyrrhocoridae)

Original language description

The hypothesis that there is a feedback between juvenile hormone and adipokinetic hormones (AKHs) was investigated by application of the juvenoid methoprene on the males of the firebug Pyrrhocoris apterus. This juvenoid induced a significant reduction ofhaemolymph lipids 24 hours after treatment; however, it did not significantly reduce the ability of Pyrap-AKH to mobilize fat body lipids 6 - 72 hours after the methoprene application. The same methoprene treatment elicited a significant increase of AKHcontent in the CNS of experimental males 24 and 48 hours after the juvenoid application. A significant decrease in the AKH level in the haemolymph was recorded under the same experimental conditions. Similar results were observed when production of theAKHs was measured under in vitro conditions. It is suggested that methoprene may reduce AKH release from the CNS resulting in an increase in the AKH content of the CNS due to accumulation rather than stimulation of AKH synthesis.
