The transmission of Leishmania involves several species of sand flies that are closely associated with various parasites and reservoirs, with differing transmission cycles in Brazil. A study on the phlebotomine species composition has been conducted in the municipality of Divinópolis, Minas Gerais, Brazil, an endemic area for cutaneous leishmaniasis (CL), which has intense occurrence of visceral leishmaniasis (VL) cases. In order to study the sand flies populations and their seasonality, CDC light traps (HP model) were distributed in 15 houses which presented at least one case of CL or VL and in five urban parks (green areas). Collections were carried out three nights monthly from September 2010 to August 2011. A total of 1064 phlebotomine specimens were collected belonging to two genera and seventeen species: Brumptomyia brumpti, Lutzomyia bacula, Lutzomyia cortelezzii, Lutzomyia lenti, Lutzomyia sallesi, Lutzomyia longipalpis, Lutzomyia migonei, Lutzomyia intermedia, Lutzomyia neivai, Lutzomyia whitmani, Lutzomyia christenseni, Lutzomyia monticola, Lutzomyia pessoai, Lutzomyia aragaoi, Lutzomyia brasiliensis, Lutzomyia lutziana, and Lutzomyia sordellii. L. longipalpis, the main vector of Leishmania infantum in Brazil, was the most frequent species, accounting for 76.9% of the total, followed by L. lenti with 8.3%, this species is not a proven vector. Green and urban areas had different sand flies species composition, whereas the high abundance of L. longipalpis in urban areas and the presence of various vector species in both green and urban areas were also observed. Our data point out to the requirement of control measures against phlebotomine sand flies in the municipality of Divinópolis and adoption of strategies aiming entomological surveillance.
利什曼原虫的传播涉及几种沙蝇,这些沙蝇与各种寄生虫和宿主密切相关,在巴西具有不同的传播周期。在巴西的迪维诺波利斯市(Divinópolis)进行了一项关于白蛉物种组成的研究,该地区是皮肤利什曼病(CL)的地方病流行区,内脏利什曼病(VL)病例发生率很高。为了研究沙蝇种群及其季节性变化,每月在有至少一例 CL 或 VL 病例的 15 户家庭和五个城市公园(绿地)中使用 CDC 诱捕器(HP 模型)进行采集。2010 年 9 月至 2011 年 8 月,每月进行三次夜间采集。共采集到 1064 只白蛉标本,属于两个属和十七个种:Brumptomyia brumpti、Lutzomyia bacula、Lutzomyia cortelezzii、Lutzomyia lenti、Lutzomyia sallesi、Lutzomyia longipalpis、Lutzomyia migonei、Lutzomyia intermedia、Lutzomyia neivai、Lutzomyia whitmani、Lutzomyia christenseni、Lutzomyia monticola、Lutzomyia pessoai、Lutzomyia aragaoi、Lutzomyia brasiliensis、Lutzomyia lutziana 和 Lutzomyia sordellii。L. longipalpis 是巴西利什曼原虫的主要传播媒介,占总数的 76.9%,其次是 L. lenti,占 8.3%,该种不是已知的传播媒介。绿地和城市地区的白蛉种类组成不同,而城市地区 L. longipalpis 的高丰度和绿地和城市地区各种媒介物种的存在也表明需要在迪维诺波利斯市采取针对白蛉的控制措施,并采取昆虫学监测策略。
