This juvenoid induced a significant reduction of haemolymph 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 AKH content 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 the AKHs 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.
