Abstract
During prolonged flight, locusts predominantly utilize lipids for energy generation. Lipid stores are mainly located in the fat body. Flight is accompanied by release of adipokinetic hormones from the corpora cardiaca. Under the influence of these hormones, fat body triacylglycerol is converted to diacylglycérol, which is released into the haemolymph. This release requires the presence of specific lipoproteins. The lipid mobilizing effect of adipokinetic hormone on the fat body is attended by the association of a high density lipophorin and a non-lipid containing protein, both already present in the haemolymph, and the increased amount of released lipid to form a new lipoprotein, low density lipophorin. Upon delivery of the lipid to the flight muscles, participating proteins dissociate again and can be reused for lipid uptake at the fat body (lipoprotein shuttle system). The flight-specific metabolic systems could be starting-points for new devices in control strategies.
Résumé
Durant le vol prolongé, le criquet utilise surtout les lipides comme source d’énergie. Les réserves de lipides sont principalement localisées dans le corps gras. Le vol est accompagné par la libération d’hormones adipokinétique sécrétées par les corpora cardiaca. Sous l’influence de ces hormones, le triacylglycérol du corps gras est transformé en diacylglycérol, qui est libéré dans l’hémolymphe. Cette libération demande la présence de lipoprotéines spécifiques. Parallèlement à l’effet de mobilisation des lipides de l’hormone adipokinétique dans le corps gras, il y a un regroupement d’une lipophorine de haute densité avec une protéine sans lipide, les deux composants étant déjà présent dans l’hémolymphe. Ce regroupement associé avec les lipides mobilisés forme une nouvelle lipoprotéine: la lipophorine de basse densité. Après la répartition des lipides dans les muscles du vol, le complexe des protéines est dissocié à nouveau et peut-être réutilisé pour prendre des lipides au corps gras (système de navette de lipoprotéines). La particularité du système métabolique du vol pourrait être le départ pour un moyen stratégique de contrôle du criquet.
