  abstract = {{T}riatoma infestans, the major vector of {C}hagas disease south of the {A}mazon in {S}outh {A}merica, has a large distribution of wild populations, contrary to what has previously been stated. {T}hese populations have been suspected of being the source of reinfestation of human habitats and could impede the full success of vector control campaigns. {T}his study examined gene flow between intra-peridomestic populations and wild populations collected in the surround areas in three {A}ndean localities in {B}olivia. {T}he populations were defined according to temporal, ecological, and spatial criteria. {A}fter {DNA} extraction from the legs of each insect, the samples were analyzed using seven microsatellite markers. {F}irst, the analysis of molecular variance ({AMOVA}) detected an absence of differentiation between wild and intra-peridomestic populations, although strong structuring was observed between the populations within each environment. {T}hen for some populations, the {B}ayesian method of assignment to inferred populations showed very similar assignment patterns of the members of wild or intra-peridomestic populations in each locality. {F}inally, the detection of the first-generation migrants within the different populations provided evidence of insect displacement from the wild to the intra-peridomestic environment. {T}his result indicates that, after control campaigns in the {A}ndes, controlling this new paradigm of vector transmission risk stemming from the invasion of human habitats by wild populations of {T}. infestans requires long-term maintenance of public monitoring to keep the risk at a minimal level. {S}ince wild populations of {T}. infestans have also been detected elsewhere in {A}rgentina, {P}araguay, and {C}hile, there is an urgent need to take these populations into account in future monitoring of {C}hagas disease transmission.},
