title: [Interaction of propranolol and somatostatin with the octopaminergic response of honeybee lipemia in vivo].
abstract: The injection of DL-octopamine to emerging adult honey bees (1 nanomol per individual) promptly rises the haemolymph levels of steroids, diacyl and triacylglycerols (over 100% increase occurring after 10 min). Free fatty acids are then increased (by 131%) 45 mn after injections. These responses are completely abolished by 2.5 nanomol propranolol and 0.07 nanomol cyclic somatostatin. Octopamine thus seems to be more strongly involved in the lipemia than in the glycemia regulation, by contrast with noradrenaline which is, apparently, more active on carbohydrates.
