Flebotomíneos (diptera: psychodidae) no ambiente domiciliar em área de transmissão da leishmaniose tegumentar e visceral, no município de Santarém, estado do Pará, Brasil.

Abstract

For verification presence of the phlebotomines faune in domiciliam to endemic area of the visceral and cutaneous leishmaniasis, realization, among the months of March of 2002 to February of 2003, sand flies collections were accomplished by means of snares luminous type CDC, placed in the intradomicilio (bedroom) and peridomicilio (shelters of animals) in the municipal district of Santarém, they were chosen three outlying neighborhoods of the city, where there was registration of autochthonous cases of leishmaniasis: Jutaí, Diamantino and Sto. André. 9.926 flebotomíneos was captured, distributed in 15 species, the most abundant species were L. longipalpis (59,72%) and L. carmelinoi (35,47%). In the neighborhood of Jutaí the largest amount of sand flies was captured (6.031 specimens), proceeded by the neighborhood of Diamantino (2.390 specimens) and Sto. André (1.505 specimens). larger phlebotomines presence was registered in the home (5.377) than in the peridomicilio (4.549), as the horizontal bedding had significant reduction in the fauna phlebotomines in it distances it of 400 meters of the residual forest. The sazonalite, demonstrated larger density of individuals in the months of the rainy station. The presence of leishmaniasis vectors, naturally infected with tripanossomatideos, the sand flies presence in neighborhoods of old formation and the capture of phlebotomines imatures in hen houses in the periphery of the city, of the indications of occurrence of transmission leishmaniasis peridomicliar in the periphery of Santarém. The construction of close houses the residual forest, with presence of domestic animals, composes aggravating factor for appearance of leishmaniasis outbreak in the periphery of Santarém.
