Résumé:
Triatomine bugs (Hemiptera: Reduviidae), known in Brazil with barbers, are hematophagous insect vectors of Trypanosoma cruzi, etiologic agent of Chagas disease human. The present study aimed to evaluate triatomine fauna captured in the municipalities of Curimataú and Seridó paraibanos region during Campaign Control Program of Chagas disease ( PCDCh ) in 2013 , while they conducted a retrospective survey of the species caught between 2008 and 2012 for the same region from the triatomine registration documents belonging to 4th Regional Health Management , headquartered by Cuité . Presents the triatomine species in the region, as well as species distribution by municipality, these prevalence in domestic and peridomestic environments and infection rate similar to T. cruzi flagellates. The analysis of the two periods (2013 and 2008/ 2012) considered for survey showed that 1896 copies were captured triatomine in the region, noting the presence of seven species, but with prevalence T. pseudomaculata, T. brasiliensis and P. lutzi. The counties that recorded the highest number of catches were: Barra Santa Rosa (58.1 %), Cuité (20.4 %) and Picuí (12.8%) compared to the total catches in 2013. The results of the analyzes of variance showed significant differences (P <0.05) between the developmental stage and location of capture, for T. brasiliensis and T. pseudomaculata, which were found more frequently colonizing and / or infecting, in indoors and outside the home, respectively. The infection by trypanosomes were 0.70% for insects examined in 2013, 0.08% for the species examined between 2008 and 2012 and 0.20% in the two periods studied, although low, check the indices may indicate that the cycle T. cruzi in the region remains active.
