Résumé

Quand les mouches tsétsé (Glossina austeni) se nourrissent de sang contenant du3H2O et du14C-dextran, le3H2O réapparaît après 5 min dans l'urine à des concentrations qui se rapprochent de celles de son absorption. La concentration du3H2O dans l'hémolymphe est nettement moins élevée que dans l'urine. Le14C-dextran est présent au moins dans l'urine des mouches. Ces résultats suggèrent un compartimentage de l'eau durant la diurèse, ce qui prévient la dilution de l'hémolymph.
