An entomological and serological survey of a typical village was conducted between July and September 2003. The peridomestic areas of 100 dwellings were visited and triatormines were searched manually in 369 potential sites. A total of 1821 Triatoma longipennis (93.2%) or Triatoma barberi was captured. Both species frequently occurred in sympatry. The infestation index was 60% for T longipennis and 16% for T barberi. T longipennis occurred throughout the village. Colonization indices were high for T longipennis (93%) and T barberi (75%), suggesting that both species have adapted to peridomestic habitats. The bug population size was larger for T longipennis than for T barberi. Five very large colonies of T longipennis were recorded whereas only 1 or 2 bugs were observed in 38% of the positive sites, which suggests intense dispersal activity. Both species exhibited high infection prevalence with Trypanosoma cruzi (46%). Only T cruzi lineage I was detected. Human seroprevalence was 1.8%. This study serves as an entomological overview of peridomiciliar triatomine colonization in a Mexican village and highlights the current risk of Chagas disease transmission. specialized peridomiciliar area Triatoma longipennis Triatoma barberi seroprevalence risk of transmission Mexico 052 101 3 249-257 2007 0001-706X https://www.documentation.ird.fr/hor/fdi:010037980 10.1016/j.actatropica.2007.02.007 0001-706X [F B010037980] https://www.documentation.ird.fr/hor/fdi:010037980 https://www.documentation.ird.fr/intranet/publi/2007/07/010037980.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2007-08-06 2017-08-23 fdi:010037980 fre
