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

Description
Summary:	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 Falcão 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.Foram comparados os resultados de coletas de flebotomíneos, realizadas na fazenda Jussara, no Município de Jussara, Paraná, Brasil. As primeiras coletas foram realizadas no ano de 1992, nos meses de Fevereiro, Março e Abril, antes de ter sido feito saneamento ambiental. Seis armadilhas de tipo Falção foram instaladas no domicílio e peridomicílio. Foram realizadas uma coleta por mês e um total de 35,783 flebotomíneos foram coletados. As espécies predominantes foram Lu. whitmani (84.4%), Lu intermedia (8.1%), Lu migonei (5.0%), e outros (2.5%). Na primeira coleta a média horaria foi de 3.976 (353783/9). Baseado nestes dados foi realizado uma limpeza no peridomicílio em Janeiro de 1994 (canalização das águas usadas, retirada de madeiras empilhadas e de matéria orgânica, afastamento das habitações dos animais das residências humanas e corte de árvores). Após estas medidas foi realizado nova coleta nos meses de Fevereiro, Março e Abril de 1994, totalizando 42 horas. A média horária foi de 150 (6.311/42) insetos. Prevaleceram Lu. whitmani (70,4%), Lu neivai (27,1%) e outros (2,5%). As medidas de saneamento ambiental e o afastamento dos animais domésticos do peridomicílio podem servir como medidas auxiliares para o controle de flebotomíneos , atenuando a transmissão de Leishmania para o homem no peridomicílio, em áreas endêmicas de leishmaniose tegumentar.
