From August 2001 to July 2002, sand flies were collected from the bases of trees and, using CDC and Disney traps, from areas surrounding homes and forested areas in the São João community, on the urban periphery of Manaus, State of Amazonas. 4,104 specimens belonging to four subtribes, 13 genera and 49 species of the Phlebotominae subfamily were collected. The subtribe Psychodopygina predominated, with 3,403 (83%) specimens, especially of Nyssomyia umbratilis, Nyssomyia anduzei, Trichophoromyia eurypyga, Bichromomyia olmeca nociva and Bichromomyia flaviscutellata. The occurrences of Nyssomyia umbratilis and Nyssomyia anduzei, which have been incriminated as vectors for Leishmania (Viannia) guyanensis, and of Bichromomyia flaviscutellata and Bichromomyia olmeca nociva, for Leishmania (Leishmania) amazonensis, indicate that there is a risk of infection for people living in this area. Most (98.5%) of the sand flies were caught in the forested area. Nyssomyia anduzei and Bichromomyia olmeca nociva were collected from areas surrounding homes. The richness of vector species for Leishmania in this area shows the need for constant entomological surveillance.
2001年8月至2002年7月，在亚马孙州马瑙斯市城市边缘的圣若昂社区，从树基部以及使用疾控中心（CDC）诱捕器和迪士尼诱捕器，在房屋周边区域和林区采集了白蛉。共采集到4104只标本，分属于白蛉亚科的4个亚族、13个属和49个种。Psychodopygina亚族占主导，有3403只（83%）标本，尤其是荫蚋、安氏蚋、阔臀毛蚋、诺氏双色蚋和黄盾双色蚋。已被确认为圭亚那利什曼原虫（维氏利什曼原虫）传播媒介的荫蚋和安氏蚋，以及被认为是亚马逊利什曼原虫（利什曼原虫）传播媒介的黄盾双色蚋和诺氏双色蚋的出现，表明该地区居民存在感染风险。大多数（98.5%）白蛉是在林区捕获的。安氏蚋和诺氏双色蚋是在房屋周边区域采集到的。该地区利什曼原虫传播媒介种类丰富，表明需要持续进行昆虫学监测。
