[Epidemiologic study of the sources of blood feeding of the triatominae of the Aroeira farm (Catolé do Rocha, Paraìba) and neighboring localities].
We have analysed the blood feeding sources of 94 triatomine bugs (51 T. brasiliensis, 42 T. pseudomaculata and one R. neglectus) from Fazenda Aroeira, in Catolé do Rocha Municipality, Paraíba State, and four neighbouring localities. The positivity for marsupial, man and bird blood were, respectively, 39.7, 6.2 and 23.0%. Three insects from Fazenda Aroeira were positive both for T. cruzi and marsupial blood while only one of the three was positive for another mammal. Marsupials are the most important source of T. cruzi for the insects of the area, which have little contact with man.
