Summary: | Abstract 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. RESULTS: In total, 116 triatomines of the species Eratyrus mucronatus, Rhodnius pictipes, R. stali, and R. montenegrensis were collected, of which 13.8% were positive for T. cruzi. CONCLUSIONS: Four species of triatomines presented an infection rate above 13% in the Boca do Moa community. |
