title: [Kinetics of the effect of noradrenaline, dopa and dopamine on the glycemia of bees in vivo].
abstract: Following intra-abdominal injection of noradrenaline, dopamine and dopa to living workerbees, an increase of haemolymph glucose occurred respectively after 30 min, 90 min and 120 min. In each case the trehalose first undergoes a slight increase within 30 to 45 min followed by a more important decrease becoming significant after 2 to 3 h. The kinetics effects of noradrenaline on glucose look very close to those of adrenaline, while the other two precursors seem to wear an hyperglycaemic action only after their conversion into an active form.
