The high proportion of cases of cutaneous leishmaniasis reported amongst residents in the city of Bandeirantes, in the state of Paraná, Brazil, led the authors to investigate the phlebotomine fauna in both urban and rural environments. The sandflies were captured with automatic light traps from 07:00 pm-07:00 am fortnightly in 11 urban peridomiciles from April 2008-March 2009 and monthly in three ecotopes within four rural localities from April 2009-March 2010. In one of these latter localities, sandfly capture was conducted with white/black Shannon traps during each of three seasons: spring, summer and fall. A total of 5,729 sandflies of 17 species were captured. Nyssomyia neivai (46.7%) and Nyssomyia whitmani (35.3%) were the predominant species. In this study, 3,865 specimens were captured with automatic light traps: 22 (0.083 sandflies/trap) in the urban areas and 3,843 (26.69 sandflies/trap) in the rural areas. Ny. neivai was predominant in urban (68.2%) and rural (42.8%) areas. A total of 1,864 specimens were captured with the white/black Shannon traps and Ny. neivai (54.5%) and Ny. whitmani (31.4%) were the predominant species captured. The small numbers of sandflies captured in the urban areas suggest that the transmission of Leishmania has occurred in the rural area due to Ny. neivai and Ny. whitmani as the probable vectors.
巴西巴拉那州班代兰蒂斯市报告的皮肤利什曼病病例比例较高，促使作者调查城市和农村环境中的白蛉种群。2008 年 4 月至 2009 年 3 月，每月在 11 个城市半农村地区用自动诱虫灯在晚上 7 点至早上 7 点间捕获沙蝇；2009 年 4 月至 2010 年 3 月，每月在四个农村地区的三个生态区用手动诱捕器捕获沙蝇。在其中一个农村地区，每个季节（春季、夏季和秋季）都用白色/黑色 Shannon 陷阱捕获沙蝇。共捕获 5729 只 17 种沙蝇。Nyssomyia neivai（46.7%）和 Nyssomyia whitmani（35.3%）是主要物种。在这项研究中，用自动诱虫灯捕获了 3865 只标本：城市地区捕获 22 只（每诱虫灯 0.083 只），农村地区捕获 3843 只（每诱虫灯 26.69 只）。在城市和农村地区，Nyssomyia neivai 均占优势（68.2%和 42.8%）。用白色/黑色 Shannon 陷阱共捕获了 1864 只标本，主要捕获的物种是 Nyssomyia neivai（54.5%）和 Nyssomyia whitmani（31.4%）。在城市地区捕获的沙蝇数量较少，表明由于 Nyssomyia neivai 和 Nyssomyia whitmani 可能是传播媒介，Leishmania 的传播可能发生在农村地区。
