Abstract

A study on phlebotomine sand fly occurrence was carried out from January to August, 1999, in two areas of residual forest (Estrada do Turismo and Cidade de Deus) located near lowcost housing complexes, in the periphery of Manaus (AM). The objetive of this study was to verify the sand fly fauna, and observe possible behavior changes, mainly the cutaneous leishmaniasis vectors of CDC. Light traps were placed at a height of one meter on the inside and outside of the dwellings; in addition, manual catches with glass tubes were made at the base of trees. Females were dissected in search of flagellates. In area 1 (Estrada do Turismo) 579 sand flies of 12 different species were captured, 545 in the residual forest and 33 specimens in the residence areas. In area 2 (Cidade de Deus) 976 specimens of 21 different species were captured, 883 sand fly were caught in the residual forest e 72 other specimens in the domiciliar areas. All three hundred and seventy five females dissected were negative for flagellate. Lutzomyia umbratilis Ward & Fraiha, 1997 was the most abundant species in all collecting places.
