Hello Gustavo. We carried out an assessment of the Chagas disease situation and Triatominae populations in the Tapajos region in the PLUPH project. A student, now colleague, Fernando Braga Stehling Dias, who works at Belo Horizonte ( Fiocruz Centro René Rachou) conducted studies on the origin of blood meals of the Triatominae we captured. He will be published soon his work. You can find him in Research gate and ask him. You will probably have more technical information. Regards

Christine Romana
