RESUMEN
ABSTRACT Background: An external quality assessment on the identification of triatomines within the laboratory network in the state of Rondônia. Methods: Seven laboratories participated in this evaluation. Each was provided with support materials and nine insects from the Hemiptera order for identification. Results: All samples were accurately identified at the species level. However, correct sex identification was achieved for only 79% of the samples. The most significant challenges were encountered in determining the sex of predators, phytophagous species, Rhodnius robustus, and Rhodnius pictipes. Conclusions: The identified shortcomings can inform enhancements in vector control programs for Chagas disease.
RESUMEN
Abstract INTRODUCTION: This short communication presents a novel report on the occurrence of Panstrongylus rufotuberculatus in the Brazilian state of Rondônia. METHODS: Two specimens were collected inside dwellings and identified using dichotomous keys. RESULTS: The present study showed the extensive geographic distribution of P. rufotuberculatus and the increased number of species in the state of Rondônia. CONCLUSIONS: This new record of P. rufotuberculatus is important for understanding the epidemiology of Chagas disease because this species is found naturally infected with Trypanosoma cruzi. Studies on the ecology, biology, and vector-host-parasite interactions of this species are essential for surveillance programs.
