[Blood-feeding of Rhodnius prolixus].
Triatomines (Hemiptera: Reduviidae) are blood-sucking insect vectors of the protozoan Trypanosoma cruzi which is the causative agent of Chagas' disease. Rhodnius prolixus is the most epidemiologically important vector of T. cruzi in Colombia. Triatomines are regarded to be vessel-feeders as they obtain their blood meals from vertebrate hosts by directly inserting their mouthparts into vessels. ...
متن کاملAn unusual myosuppressin from the blood-feeding bug Rhodnius prolixus.
The myosuppressin (MS) gene was cloned from a central nervous system (CNS) cDNA library of the hematophagous insect Rhodnius prolixus and is predicted to contain two introns and three exons. The mRNA transcribed from the myosuppressin gene encodes an 88 amino acid prepropeptide, which results in a mature decapeptide after post-translational modification. When compared with the myosuppressins is...
متن کاملPeptides and serotonin control feeding-related events in Rhodnius prolixus.
Rhodnius prolixus periodically gorges on a blood meal that could compromise salt and water balance. This, however, is prevented by rapid production of urine within minutes of feeding. The Malpighian tubules increase their rate of secretion 1,000 fold leading to the production of a hypo-osmotic urine that is high in NaCl content. Feeding and post-prandial diuresis in R. prolixus are tightly coor...
متن کاملInteraction of lipophorin with Rhodnius prolixus oocytes: biochemical properties and the importance of blood feeding
Lipophorin (Lp) is the main haemolymphatic lipoprotein in insects and transports lipids between different organs. In adult females, lipophorin delivers lipids to growing oocytes. In this study, the interaction of this lipoprotein with the ovaries of Rhodnius prolixus was characterised using an oocyte membrane preparation and purified radiolabelled Lp (125I-Lp). Lp-specific binding to the oocyte...
متن کاملThe Feeding Response of Rhodnius Prolixus to Blood Fractions, and the Role of Atp
Second-instar larvae of Rhodnius prolixus will gorge on washed human erythrocytes suspended in Ringer, but not on plasma, either with or without platelets. The ED 50 of erythrocytes is 4-5 vol of packed cells per 1000 vol of Ringer. Erythrocyte 'ghosts' are non-stimulatory, whereas the haemolysate induces gorging. Phagostimulation by 'ghosts' is restored by resealing them in 1 HIM adenosine tri...
