Abstract

ALDANA, Elis; ZAMORA, Ezequiel  and  LIZANO, Eliécer. Biological cycle of Rhodnius robustus Larrousse 1927 feeding with human blood in laboratory conditions. Entomol. vectores [online]. 2005, vol.12, n.1, pp. 53-60. ISSN 0328-0381.  http://dx.doi.org/10.1590/S0328-03812005000100004.

The aim of this work was the study of biological cycle of R. robustus feeding with human blood. Triatomines were collected in Caño Tigre, state of Mérida, Venezuela.Triatomines were fed through latex membrane with human blood at 37ºC and sodium citrate as anticoagulant. The results showed 13,9 eggs/female/week, a 78,32 % fertility and a biological cycle from egg to adult lasting 70 days. Breeding of R. robustus when fed with human blood shows its potential human dwelling domiciliation and Chagas Disease transmission.

Keywords : Triatominae; fitness; behavior; Rhodnius robustus.
