Panstrongylus megistus em ecótopos artificiais de ilhas do Alto Rio Paraná

Abstract

In response to complaints of triatomines on islands of the Alto Paraná River, an investigation to determine the presence of triatomines was conducted in 145 artificial ecotopes and 4 (2.8%) were infested, comprising a residence, a sports and leisure club, a former school and a woodpile. Of the 35 P. megistus collected, 17 were analyzed and 12 (70.6%) were found to be infected with Trypanosoma cruzi. Birds and rodents were the most common food sources. All serologic examinations (56 human, 18 dogs and 10 cats) were negative.

Phenetic analysis of Panstrongylus megistus Burmeister, 1835 (Hemiptera: Reduviidae: Triatominae) in the State of Paraná-Brazil

“…FalavignaGuilherme et al, (2001) have already found this species in domicile, in Paraná-BR. Another characteristic of it is its well-developed dispersing capacity, for its colonization in inhabited houses has constantly been observed in other regions of Brazil (Guilherme et al, 2001). This was the reason why the present compared the populations found in the State of Paraná and studied its genetic diversity, comparing it to those of other Brazilian states.…”

Foco de doença de Chagas em Arcádia, estado do Rio de Janeiro, Brasil

“…Panstrongylus megistus Burneister, 1835, 70,6% apresentavam-se infectados por T. cruzi e alimentando-se em ave, roedor e cão, no alto do Rio Paraná, Santa Catarina (Guilherme et al 2001).…”

Evaluation of natural foci of Panstrongylus megistus in a forest fragment in Porto Alegre, State of Rio Grande do Sul, Brazil

“…Aragão 46 showed that humidity followed by lower temperatures produces a greater wet surface permanence in residences, making such habitats unsuitable for these triatomines. However, the presence of P. megistus in artifi cial habitats in the States of Santa Catarina and Paraná demonstrates the species' ability to colonize this environment in the southern region of the country, even at a low intensity 50,51 . In the State of Rio Grande do Sul, the fi rst domiciliary species focus was described by Di Primio 30 in the municipality of Viamão.…”
