Abstract
This study reports the results from sandfly captures at six sites in a rural area of Japurá, Paraná State, Brazil, showing the vector's presence indoors, outdoors, and in residual forest. Sandfly captures were performed with Falcão traps from 8:00 AM to 3:00 PM. At sites 195, 223, 236, and 527, three captures were performed at different times from December 2007 to January 2009. At sites 175 and 218, captures were performed from January to December 2008. 8,453 sandflies were captured, with an average of 155.40 specimens per hour. Nyssomyia neivai was the predominant species. Most sandflies were captured in domestic animal shelters (75.91 per hour) and in ciliary forest (38.45 per hour) during the hottest and rainiest months, in the outdoor environment with accumulation of organic matter and inadequate disposal of household wastewater. The study emphasizes the need for regular outdoor cleaning around households and building domestic animal shelters far from residences.

As leishmanioses tegumentar e visceral estão distribuídas em 88 países, especialmente em áreas tropicais e subtropicais da Ásia, África e Américas 1
A ocorrência de leishmaniose tegumentar americana (LTA) em municípios do noroeste paranaense mostra a necessidade de estudos sobre o comportamento de flebotomíneos que possam nortear os trabalhos de controle desses insetos
Nesses lotes as coletas foram feitas uma vez por mês, de janeiro a dezembro de 2008, das 20 às 3 horas, num total de 84 horas por ecótopo
Summary
O Município de Japurá localiza-se entre 23o-24oS e 52o-53oO (Figura 1), no noroeste do Estado do Paraná, Brasil. Nesses lotes as coletas foram feitas uma vez por mês, de janeiro a dezembro de 2008, das 20 às 3 horas, num total de 84 horas por ecótopo. As espécies mais numerosas foram Ny. neivai e Ny. whitmani (Tabela 1). As espécies de flebotomíneos descritas em Japurá foram anteriormente assinaladas em diversos municípios do Estado do Paraná 5,10. Ambas as espécies são dominantes em diversas áreas endêmicas de LTA nos estados do sul do Brasil 3,10,11. A primeira espécie foi detectada com infecção natural por Leishmania no Ceará e a segunda nos estados do Paraná Santa Catarina e Rio Grande do Sul 15. Nos lotes 223 e 236, coletaram-se cinco e três espécies de flebotomíneos e apenas 10 e 14 exemplares, respectivamente.
