Evaluation of Sandfly Control Measures in Northern Prana State, Brazil

Sandfly captures from April 2001-September 2002 were compared to those from October 1996-September 1997 & October 1998-April 2000 in order to evaluate control procedures conducted in Recanto Marista in the county of Doutor Camargo, Parana State, Brazil. Sandflies were captured with Falcao traps twice a month, both in the domiciles & henhouses, from 10 PM to 2 AM. In 2001-2002, 199,821 sandflies were captured, with an hourly average of 1,625.5 insects; average captures in 1996-1997 & 1997-1998 were 1,641.9 & 806.7, respectively. Nyssomyia neivai was the most abundant species (90.4%) in all habitats. This species, together N. whitmani, Migonemyia migonei, & Pintomyia fischeri, accounted for 99.9% of all the specimens captured. The total hourly average sandfly captures increased, but 85% of these insects were captured in henhouses built with the purpose of attracting sandfly specimens, while the density decreased in other environments, especially intradomiciliary.
