Abstract

This research was conducted in Nuevo Zapotal, Los Ríos province, Ecuador. There
was no previous evidence of Chagas until 2002. In this year, an acute case of Chagas
and the presence of Rhodnius ecuadoriensis in intradomicile were reported. With
this information, active entomological searches were conducted and training of the
population of the localities was conducted to detect the presence of triatomines.
A total of 110 houses, from 4 localities, were examined and an infestation rate of
11.8% was determined. Three species were found (R. ecuadoriensis, Panstrongylus
rufotuberculatus, Triatoma dimidiata). Nymphs of R. ecuadoriensis and T. dimidiata
were found inside of houses, these findings showed that the process of colonization
could be involved. These results extend the range of distribution of these species and
posed the importance of continuing with research to determine the epidemiological
importance of these findings in Trypanosoma cruzi transmission in the studied area.
