Description
Summary:The C. cerifera palm tree (carnaúba) is widely distributed in the Northeastem Brazil, including the State of Piauí. This investigation revealed that R. nasutus is the ortly triatomine species captured on that palm tree, in five different localities. 78% of palm trees were infested with triatomines, and 4.0% were infected with flagellates morphologically and biologically indistinguishable from Trypanosoma cruzi. Birds, rodents and marsupials were found as major blood meai sources for R. nasutus. A palmeira C. cerifera (carnaúba) é largamente distribuída no Nordeste do Brasil onde está situado o Estado do Piauí. Esta investigação revelou que R. nasutus foi a única espécie de triatomíneo capturada neste tipo de palmeira, na área rural deste Estado, em cinco localidades diferentes. Setenta e oito por cento das palmeiras estavam infestadas com triatomíneos, dos quais 4,0% estavam infectados com flagelados morfologicamente e biologicamente indistingüíveis do T. cruzi. Aves, roedores e marsupiais foram identificados como as principais fontes alimentares para o R. nasutus.
