American tegumentary leishmaniasis is endemic to the Espírito Santo State, Brazil, where it is widely distributed. The composition of the phlebotomine sand fly fauna in an American tegumentary leishmaniasis focus was determined by monthly sampling, using Shannon light traps in an Atlantic Forest reserve and adjacent habitat that had been modified by human activity. Seasonal fluctuations in numbers of the most abundant species were also monitored from June 2004 to May 2006. Of the 6,176 specimens collected, 47.4% were captured in the forest and 52.6% in the disturbed habitat. Although Lutzomyia davisi (60.8%) predominated in specimens from the forest, those captured near human dwellings consisted almost entirely of Lu. choti (72%) and Lu. intermedia (24.3%). All three species occurred throughout the year. Based on our findings, Lu. intermedia probably acts as the principal domestic Leishmania vector in the study area.
美洲皮肤利什曼病在巴西圣埃斯皮里图州呈地方性流行，该病在该州广泛传播。通过每月采样，利用香农诱虫灯陷阱，对大西洋森林保护区以及受人类活动影响的邻近栖息地进行采样，确定了美洲皮肤利什曼病疫源地的白蛉种类组成。2004年6月至2006年5月期间，还监测了数量最多的物种的季节性波动情况。在采集的6176个标本中，47.4%在森林中捕获，52.6%在受干扰的栖息地捕获。虽然来自森林的标本中，达氏罗蛉（60.8%）占主导地位，但在人类住所附近捕获的标本几乎全部是乔氏罗蛉（72%）和中间罗蛉（24.3%）。这三种物种全年均有出现。根据我们的研究结果，中间罗蛉可能是研究区域内主要的家栖利什曼原虫传播媒介。
