External quality assessment of the entomological identification of triatomines in the network of public laboratories in Rondônia, Brazil

Abstract

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.
