Information on phlebotomine collections in an area with a high level of human interference, in S. Jorge do Ivaí county, Paraná State, Southern Brazil, is reported. Lutzomyia (Nyssomyia) intermedia (Lutz & Neiva, 1912) was the dominant species. The number of sandflies in domiciles decreased sharply in the second period of collection. This occurred because a pigsty was moved to a distance of approximately 100 meters from the houses by and because the basement of one the houses was cleaned out.
