Recording and survey of Triatomine fauna (Hemiptera: Reduviidae: Triatominae) distributed in different biomes of the state of Mato Grosso, central region of Brazil

The Triatominae subfamily includes 158 currently existing species, three of which are fossils. Several species of them can transmit the parasitic protozoan Trypanosoma cruzi (Chagas, 1909), the causative agent of Chagas disease (CD), significantly impacting public health in Latin American countries. In this way, the species presente in the central region of Brazil were characterized with a focus on the state of Mato Grosso (MT) and its respective municipalities. Clarification of these factors can hel in the design of vector control strategies. From 2001 to 2024, collections were carried out in 94 municipalities of the state of MT, with active capture of triatomine specimens. A total of 1,720 specimens of triatomines belonging to five genera were collected: Triatoma Laporte, 1832 (1,357; 78.9%), Panstrongylus Berg, 1859 (224; 13%), Rhodnius Stål, 1859 (130; 7.6%), Eratyrus Stål, 1859 (8; 0.5%) and Psammolestes Bergroth, 1911 (1; 0.1%). In the faunistic analysis of the captured species. Triatoma sordida (Stål, 1859) (1,394, 81%) was characterized as the most abundant, being very frequent, constant and dominant species in the Central-West region of Brazil. The present study aims to contribute to health surveillance by identifying the species existing in the state and presenting the potential vector risk of these species for CD.
