Abstract

GUHL, Felipe; AGUILERA, Germán; PINTO, Néstor  and  VERGARA, Daniela. Updated geographical distribution and ecoepidemiology of the triatomine fauna (Reduviidae: Triatominae) in Colombia. Biomédica [online]. 2007, vol.27, suppl.1, pp.143-162. ISSN 0120-4157.

Information concerning triatomine records from provinces and municipalities was accumulated-including data indicating natural infections with trypanosomatides-that has been previously published or reported by Colombian provincial health services and research institutes. Altitude appeared to be the main factor responsible for the distribution of the insects. Illustrations summarize the information provided by the above records. A triatomine fauna classification is presented that corresponds to the eco-epidemiological conditions of the country, considering altitude as the factor determining the geographical distribution of these vectors. Rhodnius prolixus, Triatoma dimidiata, Triatoma maculata and Triatoma venosa are considered the major transmission risk species in Colombia, according to the frequency in which they are reported inside dwellings and peridomiciliary areas. Entomological surveillance providess a necessary tool to reinforce the control strategies for Chagas disease. This also allows the evaluation of transmission risk that the sylvatic triatomines represent in Colombia.

Keywords : Triatominae; ecology; vector; geographic locations; Chagas disease; vector control.
