Environmental sanitation and peri-domiciliar organisation as auxiliary practices for the control of phlebotomines in Paraná state, southern Brazil

摘要

Studies were conducted to compare the results of the collections of phlebotomines, in two distinct periods, i.e. before and after changed environmental conditions in Jussara county, Paraná State, Brazil. Collections were made near to a forest in Jussara farm, between February and April 1992. Six Falc?o light traps were installed in houses and animals' shelters. Catches were made once a month and 35,783 phlebotomines were captured. Based on these data, sanitation was done in peridomiciliary area and domestic animals shelters were separated from domiciles in January 1994. Then during February to April 1994 using the same methodology new phlebotomines catches were made. The results showed that an average of just 150 (6,311/42) phlebotomines per hour were collected at this time in contrast with an average of 3,976 (35,783/9) in 1992. The separation of domestic animals shelters from human dwelling may contribute to diminish the phlebotomine population and attenuate the risk of Leishmania transmission in endemic areas of cutaneous leishmaniasis.
