Female Anopheles freeborni discharge urine rapidly and copiously for a brief time after taking a meal of blood. This diuresis begins immediately upon cessation of feeding and continues for about 30 min at a constant rate. A decline in this rate follows and diuresis is completed by 50 min after feeding. This time-course of diuresis is independent of the size of the meal; diuresis after large meals occures at a higher rate, not over a longer time, than diuresis after small meals. Heat-stable and saline-soluble substances that induce rapid excretion by isolated Malpighian tubules can be extracted from the head and thoracic nervous system, suggesting the presence of a neurosecretory diuretic hormone similar to that found in other blood-sucking insects. Decapitation or section of the ventral nerve cord abolishes the rapid phase of diuresis after a bloodmeal. Therefore, in analogy to the situation in the tsetse fly, the head is required either as the source of a diuretic hormone or as link in the pathway that stimulates its release. © 1978.
