[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 کاملThe Proctolin Gene and Biological Effects of Proctolin in the Blood-Feeding Bug, Rhodnius prolixus
We have reinvestigated the possible presence or absence of the pentapeptide proctolin in Rhodnius prolixus and report here the cloning of the proctolin cDNA. The transcript is expressed in the central nervous system (CNS) and some peripheral tissues. The proctolin prepropeptide encodes a single copy of proctolin along with a possible proctolin-precursor-associated peptide. We have biochemically...
متن کاملPhysiological Activity of Neuropeptide F on the Hindgut of the Blood-Feeding Hemipteran, Rhodnius prolixus
Current hypotheses propose that, in the invertebrates, neuropeptide F (NPF), the vertebrate NPY homologue, may be capable of regulating responses to diverse cues related to nutritional status and feeding. An investigation into the effects of Drosophila melanogaster NPF (DrmNPF) and Anopheles gambiae NPF (AngNPF) on hindgut physiology of Rhodnius prolixus Stal (Heimptera: Reduviidae) suggests a ...
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...
