Brazil is one of the countries that concentrates 90% of all tegumentary and visceral leishmaniases cases and Bahia is one of the highly affected states. In the present report, we consolidated secondary data from several complementary databases that allowed us to record the sand fly species identified including areas of Leishmania spp. transmission in the state of Bahia. We then overlayed the geographical distribution data onto maps of vegetational aspects found across the state. Overall, 21 602 records of phlebotomine sand flies occurrence between 1949 and 2016 were analysed, encompassing 85% of Bahia's municipalities. Seventy-six sand fly species under 17 genera were enlisted. Among described species, 27 were proven or putative Leishmania spp. vectors and three were considered exclusively endemic in the state. Lutzomyia longipalpis, Nyssomyia intermedia and Nyssomyia whitmani were found in 74, 29 and 27% of municipalities, respectively. Salvador, the state capital and major city presented records for 21 different sand fly species, including known vectors for leishmaniasis. In particular, a wide distribution of Evandromyia sallesi was detected for this city. This consolidated account on phebotomine fauna and distribution may be explored for improving the planning and deployment of vector-focused leishmaniasis control measures in affected areas of Bahia.
巴西是集中了 90%的皮肤和内脏利什曼病病例的国家之一，而巴伊亚州是受影响最严重的州之一。在本报告中，我们整合了来自多个补充数据库的二级数据，这些数据使我们能够记录在所研究的巴伊亚州发现的按蚊种类，包括利什曼原虫传播的区域。然后，我们将地理分布数据叠加在该州的植被方面的地图上。总体而言，我们分析了 1949 年至 2016 年之间的 21602 份按蚊发生记录，涵盖了巴伊亚州 85%的城市。在登记的 17 属 76 种按蚊中，有 27 种被证明或可能是利什曼原虫的传播媒介，有 3 种被认为是该州特有的。在 74%、29%和 27%的城市中分别发现了长角血蜱、中间按蚊和 whitmani 按蚊。作为州首府和主要城市的萨尔瓦多记录了 21 种不同的按蚊，包括已知的利什曼病传播媒介。特别是，该城市检测到广泛分布的 Evandromyia sallesi。这种对按蚊区系和分布的综合描述可能会被用来改进规划和部署受影响地区的利什曼病媒介控制措施。
