[Sandflies in rural localities in northwest Paraná State, Brazil]

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.
