For the identification of Triatoma sordida feeding sources, using the precipitin test, authors studied 459 specimens collected in perydomiciliary environment and into the houses, in the North region of Goiás. 87 out of total numbers were from the Municipality of Damianopolis, 2 2 from Posse and 350 Aciara, subdistrict from Posse An eclectic behavior was observed having a high incidence for avian anti-sera in Damianopolis : 27 specimens (31,03%) for anti-avian, 12 (13,79%) for rodent, 9 (10,34%) for goat/ox, 7 (8,04%) for marsupials, 5 (5,57%) for humans, 2 (2,29%) for pig and 2 (2,29%) for horse. The material from Posse showed 9 specimens (40,90%) for avian, 4 (18,18%) for rodent, 3 (13,63%) for marsupials and 1 (4,54%) for each one offolowing animals: goat/cow and pig. In Aciara 112 specimens (32%) were positive for avian, 68 (19,42%) for rodent, 30 (8,57%) for goat/cow, 26 (7,42%) for horse, 23 (6,57%) for marsupials, 14 (4%) for pig and 12 (3,42%) for human. The result permit to confirm the preference of T. sordida for avian feeding sources as already described by others articles. The sample obtained did not react with anti-sera of dog, cat, armadillo, sheep, lizard and toad. Anti-sera employed in this study were anti-human, avian, cat, dog, horse, goat, cow, pig, rodent, marsupial, armadillo, sheep, lizard and toad.
