In West Mexico, Meccus longipennis plays an important epidemiological role. To understand the genetic structure of the domestic and wild populations of this species, a preliminary study with five polymorphic microsatellite loci was conducted. The population genetics analysis showed high structuring between peridomestic biotopes, with breeding subunits detected in a single peridomestic structure. In the wild environment, two genetic patterns were observed according to the biotope, possible breeding subunits in large rocky formations and a larger panmictic unit in agropastoral areas, suggesting considerable dispersal of bugs in this biotope. Moreover, the discovery of two foci of wild populations at the edge of Guadalajara city raises the question of new urban areas where the phenomenon of bug incursions into households could constitute a risk of transmission of Chagas disease. specialized Chagas disease Triatomine Mexico Population genetics Microsatellite 052 12 2 254-262 2012 1567-1348 https://www.documentation.ird.fr/hor/fdi:010055788 10.1016/j.meegid.2011.11.003 1567-1348 [F B010055788] https://www.documentation.ird.fr/hor/fdi:010055788 https://www.documentation.ird.fr/intranet/publi/2012/05/010055788.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2012-06-01 2024-06-14 fdi:010055788 fre
