Although the country has been since 2008 considered as one of the countries that succeeded in interrupted the vector transmission of Chagas by Triatoma infestans<\/jats:italic> in houses of the eastern region, there are nine other species notified in the country that are potential vectors and also deserve attention from vector control programs. Thus, we carried out an entomoepidemiological study of T. sordida<\/jats:italic> in the eastern and western regions of the country and we developed an identification key for Paraguay's triatomines based on cytogenetic data. Between the years 2003 to 2004, 271 specimens of T. sordida<\/jats:italic> were captured in domestic, peridomestic, and wild ecotopes, with 131 insects caught in the eastern (Alto Paraguay, Boquer\u00f3n and Pte. Hayes) and 140 in the western region of Paraguay (Guair\u00e1 and Paraguar\u00ed). High rates of peridomicillary infestation were observed for both regions. Besides that, the natural infection of the captured insects was detected by optical microscopy in 12% and 10%, and by PCR in 21% and 20% in the eastern and western regions, respectively. Based on cytogenetic data from nine of ten species notified in Paraguay, an identification key was developed to differentiate all taxa. Thus, given the vectorial importance of T. sordida<\/jats:italic>, we highlight the need for continued attention from Paraguay's vector control programs for this species. Further, we provide a taxonomic key that assists in the correct classification of Paraguayan triatomines.<\/jats:p>","DOI":"10.4269\/ajtmh.20-1454","type":"journal-article","created":{"date-parts":[[2021,6,7]],"date-time":"2021-06-07T16:01:16Z","timestamp":1623081676000},"source":"Crossref","is-referenced-by-count":6,"title":["Chagas Disease Vectors of Paraguay: Entomoepidemiological Aspects of Triatoma sordida (St\u00e5l, 1859) and Development of an Identification Key for Paraguayan Triatomines Based on Cytogenetics Data"],"prefix":"10.4269","author":[{"given":"Nilsa Elizabeth","family":"Gonzalez Britez","sequence":"first","affiliation":[{"name":"1Departamento de Medicina Tropical, Instituto de Investigaciones en Ciencias de la Salud (IICS), Universidad Nacional de Asunci\u00f3n, Campus Universitario, San Lorenzo, Paraguay;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaio Cesar Chaboli","family":"Alevi","sequence":"additional","affiliation":[{"name":"2Universidade Estadual Paulista \u201cJ\u00falio de Mesquita Filho\u201d (UNESP), Instituto de Bioci\u00eancias de Botucatu, Rua Dr. Ant\u00f4nio Celso Wagner Zanin, Distrito de Rubi\u00e3o Junior, Botucatu, SP, Brazil;"},{"name":"3Laborat\u00f3rio de Parasitologia, Universidade Estadual Paulista \u201cJ\u00falio de Mesquita Filho\u201d (UNESP), Faculdade de Ci\u00eancias Farmac\u00eauticas, Rodovia Araraquara-Ja\u00fa km 1, Araraquara, SP, Brazil;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ariane Cristina","family":"Caris Garcia","sequence":"additional","affiliation":[{"name":"2Universidade Estadual Paulista \u201cJ\u00falio de Mesquita Filho\u201d (UNESP), Instituto de Bioci\u00eancias de Botucatu, Rua Dr. Ant\u00f4nio Celso Wagner Zanin, Distrito de Rubi\u00e3o Junior, Botucatu, SP, Brazil;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Clara Elena","family":"Mart\u00ednez Purroy","sequence":"additional","affiliation":[{"name":"4Laboratorio de Biolog\u00eda Molecular de Protozoarios, Facultad de Medicina, Instituto de Medicina Tropical, Universidad Central de Venezuela, Los Chaguaramos, Caracas, Venezuela;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cleber","family":"Galv\u00e3o","sequence":"additional","affiliation":[{"name":"5Laborat\u00f3rio Nacional e Internacional de Refer\u00eancia em Taxonomia de Triatom\u00edneos, Instituto Oswaldo Cruz (FIOCRUZ), Pavilh\u00e3o Rocha Lima, Rio de Janeiro, RJ, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hern\u00e1n Jos\u00e9","family":"Carrasco","sequence":"additional","affiliation":[{"name":"4Laboratorio de Biolog\u00eda Molecular de Protozoarios, Facultad de Medicina, Instituto de Medicina Tropical, Universidad Central de Venezuela, Los Chaguaramos, Caracas, Venezuela;"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2795","container-title":["The American Journal of Tropical Medicine and Hygiene"],"original-title":[],"link":[{"URL":"https:\/\/www.ajtmh.org\/view\/journals\/tpmd\/aop\/article-10.4269-ajtmh.20-1454\/article-10.4269-ajtmh.20-1454.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.ajtmh.org\/downloadpdf\/journals\/tpmd\/aop\/article-10.4269-ajtmh.20-1454\/article-10.4269-ajtmh.20-1454.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,6,7]],"date-time":"2021-06-07T16:01:17Z","timestamp":1623081677000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ajtmh.org\/view\/journals\/tpmd\/aop\/article-10.4269-ajtmh.20-1454\/article-10.4269-ajtmh.20-1454.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,6,7]]},"references-count":0,"URL":"https:\/\/doi.org\/10.4269\/ajtmh.20-1454","relation":{},"ISSN":["0002-9637","1476-1645"],"issn-type":[{"value":"0002-9637","type":"print"},{"value":"1476-1645","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,6,7]]}}}
