Resumo em Inglês
Rhodnius prolixus is the main vector of Chagas disease in Venezuela. Here, domestic infestations of poor
quality rural housing have persisted despite four decades of vector control. This is in contrast to the Southern Cone region
of South America, where the main vector, Triatoma infestans, has been eliminated over large areas. The repeated
colonisation of houses by silvatic populations of R. prolixus potentially explains the control difficulties. However, controversy
surrounds the existence of silvatic R. prolixus: it has been suggested that all silvatic populations are in fact Rhodnius robustus,
a related species of minor epidemiological importance. Here we investigate, by direct sequencing (mtcytb, D2) and by
microsatellite analysis, 1) the identity of silvatic Rhodnius and 2) whether silvatic populations of Rhodnius are isolated from
domestic populations.
