Morales Multidisciplinaria (Ciencias Naturales y Exactas) hormones fluid secretion Rhodnius prolixus Malpighian tubules Rhodnius prolixus Malpighian tubules (MTs) are a good model for fluid and ion secretion studies in view of the dramaticpostprandial diuresis, which follows its massive blood meals. Ingestion of a blood meal equals to 10-12 times their initialbody mass, leads to rapid activation of high output by excretory system, which eliminates 40-50% of the fluid mass.Secretion of ions and water is stimulated 1000-fold by serotonin and diuretic hormone. These hormones cooperatesynergistically to activate adenylate cyclase activity from MTs cells, which increase the level of intracellular cAMP.The anti-diuretic hormones have also an important role in the fluid maintenance of Rhodnius prolixus. Several hoursafter insect feeding occurs a reduction in urine flow, that has been thought to result from a decreased diuretic hormonerelease or from a novel mechanism of anti-diuresis involving insect cardioacceleratory peptide 2b (CAP2b) and cyclicGMP.
