Published: 19 May 2021
...Natalia Capriotti; Paula Gioino; Sheila Ons; Juan P. Ianowski ABSTRACT Rhodnius prolixus is a blood-feeding insect vector of Tr y panosoma cruzi , a protozoan parasite that causes Chagas disease. During each blood meal, the animals ingest large volumes of blood, that may be up to 12 times the unfed...

...Geoffrey M. Coast SUMMARY The pioneering work of Simon Maddrell established that the rapid postprandial diuresis of the haematophagous insect Rhodnius prolixus is controlled by a diuretic hormone and demonstrated the role of the Malpighian tubules in meeting the volumic, osmotic and ionic...

...Victoria A. Te Brugge; David A. Schooley; Ian Orchard SUMMARY Diuresis in the blood-gorging hemipteran Rhodnius prolixus is under neurohormonal control and involves a variety of processes and tissues. These include ion and water movement across the epithelium of the crop and the Malpighian tubules...

... not affect intracellular pH. However, intracellular pH shifted 0.25 pH units more acid in Na + -free saline, suggesting that a Na + -dependent pH regulatory mechanism is at play in steady state pH regulation during fluid secretion by Malpighian tubules of Rhodnius prolixus . The data are consistent...

...Jean-Paul Paluzzi; Ian Orchard SUMMARY In the haematophagous insect Rhodnius prolixus , diuresis is accomplished through the combined actions of peptidergic diuretic hormones and 5-HT released from neurohaemal sites on the abdominal nerves. Preliminary work on anti-diuresis in this blood-feeder...

...C. S. Bjornsson; E. Huebner SUMMARY The spatiotemporal dynamics of transmembrane hydrogen ion (H + )fluxes during oogenesis were investigated in the telotrophic ovarioles of the insect, Rhodnius prolixus . Although Rhodnius ovarioles possess exaggerated morphological and electrical polarity between...

... of Rhodnius prolixus and Drosophila melanogaster . Secretion rates of Rhodnius tubules in amino-acid-free saline increase after addition of serotonin to a peak value, then slowly decline to a plateau. Addition of glutamine, glutamate or aspartate to such tubules increases secretion rates dramatically relative...

...Juan P. Ianowski; Robert J. Christensen; Michael J. O'Donnell SUMMARY Intracellular ion activities ( a ion ) and basolateral membrane potential ( V bl ) were measured in Malpighian tubule cells of Rhodnius prolixus using double-barrelled ion-selective microelectrodes. In saline containing 103mmoll...
