Reorganization and cleanness of peridomiciliar area to control sand flies (Diptera, Psychodidae, Phlebotominae) in South Brazil

The objective of the present work was to evaluate the impact of the reorganization and cleaning of the peridomicily seeking the control of Phlebotominae vectors of Leishmania. Collections of insects were made in domestic animal shelters and in peridomiciliar area located in Jussara farm, Municipality of Jussara, State of Parana, Brazil where cutaneous leishmaniasis has been endemic. The collections were accomplished five nights for month of the 21:00pm for fie hours, in 1996 and 1997. The results were compared the those obtained in the same places in 1992 and 1994. After the collections of 1992 peridomiciliar area was cleaned mid organic matter was removed mid domestic animals were reallocated. hi 1992, 1994 and 1996197, 10, 7 and 12 Phlebotominae species were observed. Lutzomyia (Nyssomyia) whitmani was predominant species in whole the collection. The total population of phlebotomine in 1992 was 64,725. A er the reorganization measures and cleaning the phlebotomine population decrease in 90%. In 1996/97 the environmental conditions retaked the patterns of the beginning of the work and the population increased for 61.51%. The present work demonstrates that the reorganization and cleaning of the peridomicily can take to a decrease in the Phlebotominae population and like this to decrease the risk of transmission of Leishmania in endemic areas.
