So far Bolivia is the only country where true T. infestans wild foci are documented. The dispersal ability for wild T. infestans was studied at microgeographical scale in Bolivian Andes, to assess the possibility for wild populations to actively recolonize insecticide-treated villages. Nine microsatellite loci were used to detect the extent of gene flow between neighbouring collecting sites. The detection of restricted gene flow between close but distinct sylvatic sites supports the hypothesis that wild T. infestans does not disperse by flying at high altitude (2 750 m asl). It gradually disperses over small distances by walking within a 'patch' of continuous land cover. The genetic differentiation detected between sylvatic and domestic populations suggests a limited short-term role of wild insects in the process of recolonization of insecticide-treated houses in the Andes. specialized chagas disease Triatoma infestans dispersal microsatellite Bolivia 052 12 6 759-764 2007 1360-2276 https://www.documentation.ird.fr/hor/fdi:010040653 10.1111/j.1365-3156.2007.01846.x 1360-2276 [F B010040653] https://www.documentation.ird.fr/hor/fdi:010040653 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2024-12/010040653.pdf IRD - Base Horizon / Pleins textes 2007-09-04 2024-12-24 fdi:010040653 fre
