Abstract

To complement the epidemiological data and assist in the prophylaxis of Chagas disease in the State of Sao Paulo, we examined entomological lifting conducted in 40 municipalities of the Western region of the state from 2004 to 2008, highlighted the main vector species in this region, and reanalyzed the cytogenetic characteristics of Rhodnius neglectus from 3 different Brazilian states (Formoso/GO, Frutal/MG, Guaira/SP, and Pitangueiras/SP). The municipalities of Castilho and Santo Antonio do Acarangua registered the highest relative amounts of notifications. The main species notified in Western Sao Paulo were Triatoma sordida and R. neglectus. We collected a large number of T. sordida in 2005 and noted the absence of notification of infected insects in 2008. We observed no variation in chromosomal characteristics of R. neglectus of different states. These data are complementary to the survey presented from 1990 to 1999, as the vector species were the same (T. sordida and R. neglectus), with emphasis on T. sordida. We corroborate the future colonization domiciliary initially proposed for T. sordida in the region and underscore the importance of vector control programs in the prophylaxis of Chagas disease. Furthermore, we observed that the populations of R. neglectus in Brazil showed no intraspecific variation and we corroborated the chromosomal patterns originally described. These data are important for understanding the evolution of these hematophagous insects, which are vectors of Chagas disease. (AU)
