Resumo: | The development of spontaneous colonies of Panstrongylus megistus in experimental fowlhouses showed regional variation with positive results in regions with an annual dry season, and negative ones in regions without this well-marked period. Beside this, the influence of the forest cover was suggested. Places with forest relics are shelters of the insect populations developing a higher ecological valence with a tendency to artificial ecotope invasion. Populations living in the more primitive and extensive forest environment of the Serra do Mar system seem to preserve mainly their wild behaviour, without a significant development of invasive power of artificial ecotopes. The association of this evidence, with primitive phytogeographic aspects, suggests that the dispersion center is the Serra do Mar system, from which the insect populations spread towards the west across South America. Man-made evironmental changes, mainly with forest destructions will probably enhance secondary adaptation to human dwellings. So, depending on the land utilization, the need of epidemiological surveillance should be emphasized. |

Mediante a instalação de galinheiros experimentais em regiões distintas, observou-se variação da capacidade de colonização espontânea de Panstrongylus megistus nesses ecótopos artificiais. Os resultados positivos foram obtidos em áreas de clima com inverno seco ou chuvoso mas onde a destruição da cobertura vegetal primitiva foi mais intensa. Na região de maior persistência florestal e de clima mais úmido, os resultados foram negativos. A existência de populações silvestres em ambas as zonas sugere que a segunda represente o centro de dispersão da espécie, enquanto na primeira o triatomíneo desenvolveu valência ecológica que lhe possibilita a invasão de ecótopos artificiais. Na dependência do grau de alteração e das condições de utilização do ambiente, a vigilância epidemiológica deverá ser mantida para evitar que a domiciliação do triatomíneo se transforme em problema de saúde pública.
