Abstract

Triatomines are hematophagous insects belonging to the Hemiptera order, Heteroptera suborder, family Reduviidae, and Triatominae subfamily. Currently, are admitted 148 species grouped in 18 genera and six tribes. The Rhodniini tribe is composed of 22 species, three of genus Psammolestes and 19 of the genus Rhodnius. The triatomines of the genus Rhodnius are morphologically very similar, which makes differentiation of species. Cytogenetic analysis in this genus began in 1950 with the description of the karyotype of R. prolixus. Despite the reported knowledge of the cytogenetic characteristics and cytotaxonomics these hematophagous insects of medical-sanitary importance also is necessary to expand the study on the genus Rhodnius. Thus, this project will examine the cytogenetic characteristics of species of the genus Rhodnius unstudied, in order to assist in cytogenetic, evolutionary, and taxonomic knowledge of these vectors of Chagas disease.
