Due to the fundamental role that sand flies (Diptera: Psychodidae) have in Leishmania spp. (Kinetoplastida: Trypanosomatidae) transmission, the objective of this study was to evaluate the ecology and spatial distribution of species circulating in the municipality of Seropédica, Rio de Janeiro, Brazil. A total of 17 371 specimens were collected between August 2016 and July 2017, and five species were identified: Nyssomyia intermedia (Lutz & Neiva, 1912), Migonemyia migonei (França, 1920), Nyssomyia whitmani (Antunes & Coutinho, 1939), Pintomyia pessoai (Coutinho & Barretto, 1940), and Pintomyia fischeri (Pinto, 1926). In relation to the number of sand flies collected, we observed a significant difference between rural and periurban areas and between the neighbourhoods. We observed that N. intermedia has a relatively greater adaptation to the peridomiciliary environment. This is the first report of Pi. pessoai and Pi. fischeri (only females) in Seropédica as well as the first record of the frequency of phlebotomine species focusing on some ecological indices and the spatial distribution of sand flies. The results presented here aimed to provide an insight into the spatial population dynamics of phlebotomine species in low endemic areas of American Tegumentary Leishmaniasis (ATL) in Seropédica, highlighting important areas for entomological surveillance.
由于沙蝇（双翅目：鳞翅目）在利什曼原虫属（原生动物：锥虫科）传播中起着根本作用，因此本研究旨在评估巴西里约热内卢塞罗佩迪卡市循环物种的生态和空间分布。2016 年 8 月至 2017 年 7 月期间共采集了 17371 只标本，鉴定出 5 种：中间沙蝇（Lutz & Neiva，1912）、米戈内伊沙蝇（França，1920）、惠特曼沙蝇（Antunes & Coutinho，1939）、皮索伊亚沙蝇（Coutinho & Barretto，1940）和菲舍尔沙蝇（Pinto，1926）。关于采集的沙蝇数量，我们观察到农村和城郊地区以及各街区之间存在显著差异。我们观察到，中间沙蝇对周边环境有较强的适应能力。这是皮索伊亚沙蝇和菲舍尔沙蝇（仅雌性）在塞罗佩迪卡的首次报道，也是首次记录有关某些生态指数和沙蝇空间分布的频率的针毛目物种。这里呈现的结果旨在深入了解塞罗佩迪卡低流行地区美洲皮肤利什曼病（ATL）中鳞翅目物种的空间种群动态，突出了昆虫学监测的重要区域。
