Abstract

Studies about permanence of Triatoma sordida after temporary alteration of the local vegetation are related. Results reached showed a bug resistence to the devastation of shrubby vegetation by fire. An attempt is made for to relate this particular aspect with species distribution in the S. Paulo State, Brazil. There are some analogies between the available data about this and the development of agrarian activities. Beside the climatic one, this factor may be considered as favorable to the Triatoma sordida dispersion, by the natural environmental alteration who if follows.
