[Sandflies in an areas with occurrences of human cases of American cutaneous leishmaniasis in the municipality of Seropédica, State of Rio de Janeiro].
American cutaneous leishmaniasis is caused by protozoa of the genus Leishmania, which affects the skin and mucosa. It is primarily a zoonotic infection. Sandfly surveys were conducted in four areas with occurrences of human cases of American cutaneous leishmaniasis in the municipality of Seropédica. A manual method was used to catch specimens between 6:00 pm and 10:00 pm, for 12 consecutive months. From October 2004 to September 2005, we caught 2,390 individuals belonging to four species: Lutzomyia intermedia accounted for 97.1% of the total collected, followed by Lutzomyia whitmani (1.6%), Lutzomyia migonei (1.2%) and Lutzomyia oswaldoi (0.1%). The Valão das Louças had the highest density of sandflies, followed by the localities of Km 39, Km 40 and Caçador. The low diversity of species is due to significant changes in the ecotope of the region. It is suggested that American cutaneous leishmaniasis is being transmitted by Lutzomyia intermedia in the municipality of Seropédica.
