An investigation was made about the influence of environment temperature on the infectivity of flagellate of T. cruzi Peru sample in triatomine feces by periconjuntival instilation in albino mice. The results demonstrate that infection, measured by patent parasitemia decreases when fecal suspension is maintained at 30ºC. The possible implication of these findings in relation to transmission of T. cruzi to human, in field, is briefty discussed.
