Monitoring the domiciliary and peridomiciliary invasion process of Triatoma rubrovaria in the State of Rio Grande do Sul, Brazil

Biology, diversity and strategies for the monitoring and control of triatomines - Chagas disease vectors

“…Today, field data have shown that the following sylvatic species are frequently found in domiciliary and peridomiciliary areas: Triatoma vitticeps (Stål, 1859), Triatoma rubrovaria (Blanchard, 1843) and Panstrongylus lutzi (Neiva & Pinto, 1923) (Gonçalves et al 1998, Almeida et al 2000, Freitas et al 2004, Souza et al 2008, among others. More recently, Triatoma sherlocki Papa, Jurberg, Carcavallo, Cerqueira & Barata 2002 was captured in Gentio do Ouro, in the north central part of BA, colonising human dwellings (Almeida et al 2009, unpublished observations).…”

Olfaction in vector-host interactions

“…Most of their hosts are warm-blooded vertebrates (birds and mammals), but some species live in association and feed on ectothermic animals or even are able to suck haemolymph from other insects (e.g. Almeida et al 2000).…”

Re-infestation of houses by Triatoma dimidiata after intra-domicile insecticide application in the Yucatán peninsula, Mexico

“…The interruption of natural transmission is thus underway in the Southern Cone countries (Argentina, Brazil, Bolivia, and Chile) (WHO 1997). However, recolonization of houses by migrating insects (from the same or other species) from sylvatic/peridomestic environments has been documented, as well as the reemergence of populations from surviving bugs (Forattini et al 1984, Gorla 1991, Schofield 1991, Scorza et al 1994, Gajate et al 1996, Oliveira-Filho 1997, Dujardin et al 1999, Almeida et al 2000.…”
