Le métabolisme est la somme des réactions chimiques dans un organisme. L’énergie leur permet d’effectuer la biosynthèse, le maintien des fonctions vitales et l’activité physique. Si l’énergie est transformée en chaleur nous pouvons déterminer le taux de transformation d’énergie chimique en taux métabolique (TM) et nous pouvons donc calculer les besoins énergétiques d’un animal. Le principal objectif de ce travail est d’évaluer le métabolisme énergétique chez la punaise hématophage Rhodnius prolixus. Nos résultats montrent, que le TM de l’alimentation chez R. prolixus atteint jusqu’à 17 fois le TM au repos. Le quotient respiratoire est de 0,83 pendant le repos et 0,52 pendant l’alimentation. De plus, la désactivation des protéines permettant...
