Through a citizen science program and field collections from 2012 to 2016, we collected 3,215 triatomines, mainly from Texas. Using morphological and molecular approaches, we identified seven <jats:italic>Triatoma<\/jats:italic> species and report sex, length, and blood engorgement status. Many citizen-collected triatomines (92.9%) were encountered indoors, in peridomestic settings, or in dog kennels and represent spillover transmission risk of <jats:italic>T. cruzi<\/jats:italic> to humans and domestic animals. The most commonly collected species were <jats:italic>Triatoma gerstaeckeri<\/jats:italic> and <jats:italic>Triatoma sanguisuga<\/jats:italic>. Adult <jats:italic>T. gerstaeckeri<\/jats:italic> were collected from May to September, peaking from June to July, whereas adult <jats:italic>T. sanguisuga<\/jats:italic> were active later, from June to October, peaking from July to September. Based on cross correlation analyses, peaks of captures varied by species and across years. Point pattern analyses revealed unique occurrences of <jats:italic>T. sanguisuga<\/jats:italic> in north and east Texas, <jats:italic>T. gerstaeckeri<\/jats:italic> in south and west Texas, <jats:italic>Triatoma indictiva<\/jats:italic> and <jats:italic>Triatoma lecticularia<\/jats:italic> in central Texas, and <jats:italic>Triatoma rubida<\/jats:italic> in west Texas. These relatively unique spatial occurrences suggest associations with different suitable habitats and serve as a basis for future models evaluating the ecological niches of different vector species. Understanding the temporal and spatial heterogeneity of triatomines in the southern United States will improve targeted interventions of vector control and will guide public outreach and education to reduce human and animal contact with vectors and reduce the risk of exposure to <jats:italic>T. cruzi<\/jats:italic>.<\/jats:p>","DOI":"10.4269\/ajtmh.17-0526","type":"journal-article","created":{"date-parts":[[2017,12,7]],"date-time":"2017-12-07T16:28:57Z","timestamp":1512664137000},"page":"113-121","source":"Crossref","is-referenced-by-count":78,"title":["Bionomics and Spatial Distribution of Triatomine Vectors of Trypanosoma cruzi in Texas and Other Southern States, USA"],"prefix":"10.4269","volume":"98","author":[{"given":"Rachel","family":"Curtis-Robles","sequence":"first","affiliation":[{"name":"Department of Veterinary Integrative Biosciences, Texas A&M University, College Station, Texas;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah A.","family":"Hamer","sequence":"additional","affiliation":[{"name":"Department of Veterinary Integrative Biosciences, Texas A&M University, College Station, Texas;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sage","family":"Lane","sequence":"additional","affiliation":[{"name":"Department of Epidemiology and Biostatistics, Texas A&M Health Science Center, College Station, Texas;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael Z.","family":"Levy","sequence":"additional","affiliation":[{"name":"Department of Biostatistics and Epidemiology, University of Pennsylvania School of Medicine, Philadelphia, Pennsylvania;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriel L.","family":"Hamer","sequence":"additional","affiliation":[{"name":"Department of Entomology, Texas A&M University, College Station, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2795","reference":[{"key":"b1","series-title":"Wkly Epidemiol Rec","first-page":"33","article-title":"Chagas disease in Latin America: an epidemiological update based on 2010 estimates","volume":"6","author":"World Health Organization","year":"2015"},{"key":"b2","series-title":"Clin Microbiol Rev","first-page":"655","article-title":"Trypanosoma cruzi and Chagas\u2019 disease in the United States","volume":"24","author":"Bern","year":"2011"},{"key":"b3","series-title":"Bull Am Mus Nat Hist","first-page":"123","article-title":"Revision of the Triatominae (Hemiptera, Reduviidae), and their significance as vectors of Chagas\u2019 disease","volume":"163","author":"Lent","year":"1979"},{"key":"b4","series-title":"PLoS Negl Trop Dis","first-page":"e656","article-title":"Estimating contact process saturation in sylvatic transmission of Trypanosoma cruzi in the United States","volume":"4","author":"Kribs-Zaleta","year":"2010"},{"key":"b5","series-title":"J Parasitol","first-page":"520","article-title":"The biology of the triatomine bugs native to south central Texas and assessment of the risk they pose for autochthonous Chagas disease exposure","volume":"101","author":"Wozniak","year":"2015"},{"key":"b6","series-title":"J Med Entomol","first-page":"81","article-title":"Epizootiology of Trypanosoma cruzi in southwestern North America.
