the aim of this study was to identify the fauna of phlebotomine sandflies in an area with incidence of american visceral leishmaniasis (avl) in s？o vicente férrer, a municipality (county) located in the northern zona da mata in pernambuco state, brazil. sandfly captures were conducted monthly for four nights/month from december 2002 to november 2003, by means of manual captures (with a shannon trap) and by cdc light traps. a total of 23,156 specimens of phlebotomines sandflies were collected in a remnant of the atlantic rainforest, houses, and animal shelters. lutzomyia complexa was the most prevalent species, with a frequency of 62.5% (14,445/23,156), followed by lutzomyia migonei, with 33.2% (7,677/23,156). no lutzomyia longipalpis (the main vector of leishmania chagasi in brazil and the americas) was found in the target area. some specimens were dissected, but no leishmania parasites were found.
