GUILHERME, Ana Lucia Falavigna et al. Panstrongylus megistus in artificial ecotopes on islands of the Paraná River. Rev. Soc. Bras. Med. Trop. [online]. 2001, vol.34, n.5, pp. 491-494. ISSN 0037-8682.  http://dx.doi.org/10.1590/S0037-86822001000500015.

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.
