- Molecular research and the control of Chagas disease vectors Fernando Abad-Franch Fernando A. Monteiro Multidisciplinaria (Ciencias Naturales y Exactas) DNA allozymes Triatominae Chagas disease molecular systematics ABSTRACTChagas disease control initiatives are yielding promising results. Molecular research has helped successfulprograms by identifying and characterizing introduced vector populations and by defining intervention targetsaccurately. However, researchers and health officials are facing new challenges throughout Latin America.Native vectors persistently reinfest insecticide-treated households, and sylvatic triatomines maintain diseasetransmission in humid forest regions (including Amazonia) without colonizing human dwellings. In thesescenarios, fine-scale vector studies are essential to define epidemiological risk patterns and clarify the involvementof little-known triatomine taxa in disease transmission. These eco-epidemiological investigations,as well as the planning and monitoring of control interventions, rely by necessity on accurate taxonomic judgments.The problems of cryptic speciation and phenotypic plasticity illustrate this need and how molecularsystematics can provide the fitting answers. Molecular data analyses also illuminate basic aspects of vectorevolution and adaptive trends. Here we review the applications of molecular markers (concentratingon allozymes and DNA sequencing) to the study of triatomines. We analyze the suitability, strengths andweaknesses of the various techniques for taxonomic, systematic and evolutionary investigations at differentlevels (populations, species, and higher taxonomic categories). 2005 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32777307 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.3 Vol.77
