Sylvatic triatominae of the phyllosoma complex (Hemiptera: Reduviidae) around the community of Carrillo Puerto, Nayarit, Mexico.

Research on domestic and sylvatic triatomines within the community of Carrillo Puerto and neighboring areas of Nayarit, Mexico, documented that Triatoma longipennis (Usinger) and Triatoma picturata (Usinger) were infected with Trypanosoma cruzi (L.) in both habitats. T. picturata was the predominant species in both habitats. Mouse baited-traps increased the effectiveness of collecting sylvatic triatomines, which were difficult to sample by inspecting habitats such as burrows, caves, and cliffs. The colonization of sylvatic and peridomestic habitats by Triatoma, the occurrence of high rates of infection with T. cruzi and the possibility that bugs move between habitats may require modification of current control strategies in Mexico.
