First report of Panstrongylus megistus sylvatic focus in municipality of Bambuí, state of Minas Gerais, Brazil

Abstract

In 1943, the Center for the Study and Prophylaxis of Chagas Disease, Oswaldo Cruz Foundation, state of Minas Gerais (MG), was created in the municipality of Bambuí to carry out studies related to Chagas disease in the mid-western region of MG. Since that time, several investigations have been conducted to determine the natural habitat of triatomines, but Panstrongylus megistus colonies have never been found in this region. This paper records the first finding of a P. megistus sylvatic colony in 69 years of research. The characteristics of this ecotope and its implications for the epidemiology of Chagas disease are discussed

Occurrence of Panstrongylus megistus (Burmeister, 1835) in an area under entomological surveillance in the Southeast Region of Brazil

“…The mid-western region of Minas Gerais has been important for studies on Chagas disease epidemiology, both historically and in the present day, due to the high incidence of the disease in the past and the continuing presence of triatomines, P. megistus, the most important species in the region from an epidemiological pointof-view [6][7] . The mid-western region comprises 54 municipalities coordinated by the Regional Health Management of Divinópolis (RHMD).…”
