Identification and characterization of microsatellite markers in the Chagas disease vector Triatoma infestans (Heteroptera: Reduviidae).

ABSTRACT: Triatoma infestans, the main vector of Chagas disease in the southern cone countries, is the principal target of a regional elimination program. A better understanding of its dispersal, sources of reinfestation, and insecticide resistance is key to an effective control program. To address such problems, we identified and characterized 13 microsatellite loci of T. infestans. For each locus, primer sequences and PCR conditions are presented. Allele variability and frequency were analyzed in 59 T. infestans specimens from different rural communities in northwestern Argentina; nine loci were considered suitable for population genetic studies. Departure from Hardy-Weinberg equilibrium was detected in 10/13 loci with F(IS) values ranging from 0.04 to 0.91, indicating heterozygote deficit and a p
