Introduction: Triatomines are insect vectors of Trypanosoma cruzi, the etiological agent of Chagas disease.
Methods: Triatomines were collected from households and by dissecting palm trees in the peri-urban areas of Cruzeiro do Sul (Acre); they were identified using a specific key and via genital analyses. Trypanosomatid infection was determined through microscopy and polymerase chain reaction.
Article Synopsis
- Triatomines, which are blood-feeding insects, are significant because they transmit Chagas disease, and this study reports the discovery of Rhodnius montenegrensis in Amazonas, Brazil.
- The research involved collecting Triatomines from Attalea butyracea palm trees in Guajará, where two adult female specimens of R. montenegrensis were found.
- This finding increases the known triatomine species in the Amazon from 10 to 11 and expands the presence of R. montenegrensis in Brazil from two to three states.
