Abstract
FIFTH-STAGE larvæ of Rhodnius prolixus decapitated immediately (10–20 min) after feeding have been shown1 to excrete less urine than normal controls. These results apparently contradict the report of Maddrell that “ligating the fed insect anterior to the ganglionic mass has no effect on urine production”.
