Item type: Item , “Andean” and “non-Andean” ITS-2 and mtCytB haplotypes of Triatoma infestans are observed in the Gran Chaco (Bolivia): Population genetics and the origin of reinfestation(Elsevier BV, 2011) Sergio Quisberth; Etienne Waleckx; Marcelo Monje; Boris Chang; François Noireau; Simone Frédérique BrénièreItem type: Item , New Discoveries of Sylvatic Triatoma infestans (Hemiptera: Reduviidae) Throughout the Bolivian Chaco(American Society of Tropical Medicine and Hygiene, 2012) Etienne Waleckx; Stéphanie Depickère; Renata Salas; Claudia Aliaga; Marcelo Monje; Hiber Calle; Rosio Buitrago; François Noireau; Simone Frédérique BrénièreSylvatic populations of Triatoma infestans might be involved in the recolonization of human dwellings. We report here the discoveries of new T. infestans sylvatic foci in the Bolivian Chaco. Eighty-one triatomines were caught, 38 of which were identified as T. infestans. Triatoma sordida and Panstrongylus geniculatus were the other species collected. One T. infestans and one T. sordida were infected with Trypanosoma cruzi TcI; one T. infestans was infected with TcII. These discoveries add to the debate on the geographic distribution of sylvatic T. infestans populations, the geographic origin of the species, and the epidemiological role of these populations.Item type: Item , New insights on the Chagas disease main vector Triatoma infestans (Reduviidae, Triatominae) brought by the genetic analysis of Bolivian sylvatic populations(Elsevier BV, 2011) Etienne Waleckx; Renata Salas; Nerida Huamán; Rosio Buitrago; Marie-France Bosseno; Claudia Aliaga; Christian Barnabé; Roberto Rodríguez; Faustine Zovéda; Marcelo MonjeItem type: Item , Predominance of hybrid discrete typing units of Trypanosoma cruzi in domestic Triatoma infestans from the Bolivian Gran Chaco region(Elsevier BV, 2012) Esdenka Pérez-Cascales; Marcelo Monje; Boris Chang; Rosio Buitrago; Rudy Parrado; Christian Barnabé; François Noireau; Simone Frédérique BrénièreItem type: Item , Susceptibility and resistance to deltamethrin of wild and domestic populations of Triatoma infestans (Reduviidae: Triatominae) in Bolivia: new discoveries(Instituto Oswaldo Cruz, Ministério da Saúde, 2012) Stéphanie Depickère; Rosio Buitrago; Edda Siñani; Marianne Baune; Marcelo Monje; Ronald López; Etienne Waleckx; Tamara Chávez; Simone Frédérique BrénièreBolivia is a high-endemic country for Chagas disease, for which the principal vector is Triatoma infestans (Triatominae). This is a mainly domestic species that is also found in the wild environment. Recently, an increasing number of studies have shown the importance of Triatominae resistance to insecticides, especially in Bolivia. Data regarding the susceptibility/resistance of wild and domestic populations of T. infestans to deltamethrin are presented. For the first time, domestic populations of the department of Santa Cruz were tested, showing low resistance. Although most of the wild populations were found to be susceptible to deltamethrin, three populations from three departments showed a mortality rate of less than 100%. This result is emphasised here.
