Phlebotomine sandflies are bloodsucking insects responsible for the transmission of leishmaniasis. The average annual incidence in Morocco, of this pathology, was approximately estimated in 2014 as 7.8 per 100.000 inhabitants according to the Moroccan health information service records. The study of the composition of the Phlebotomian community and its seasonal dynamics are essential for determining the appropriate and adequate means of control at the prefecture of Meknes in Central Morocco. It is with this in mind that two capture sessions per month using sticky paper traps were conducted at the sites of sandflies. A total of 982 sandflies were captured. The identification of the specimens found via the Moroccan key revealed a percentage of 73.3% belonging to the subgenus Paraphlebotomus, 6.3% to the Phlebotomus subgenus, 16.2% to Larroussius, and 4.2% of Sergentomia subgenus. , vector of human cutaneous leishmaniasis, was found as the more abundant with 73.3% followed by with 8.2%. The largest number of species was harvested in July and September with, respectively, 44.8 ph/m/night and 48.7 ph/m/night. This study also unveiled that the two high-risk Leishmanian months are July and September, hence, the need to strengthen efforts to monitor and control this disease during the vector activity period.
白蛉是传播利什曼病的吸血昆虫。根据摩洛哥卫生信息服务记录,2014年摩洛哥这种疾病的年平均发病率估计约为每10万居民7.8例。研究白蛉群落的组成及其季节动态对于确定摩洛哥中部梅克内斯省合适且充分的控制手段至关重要。出于这一考虑,每月在白蛉出没地点使用粘纸诱捕器进行两次捕获活动。总共捕获了982只白蛉。通过摩洛哥分类检索表对所发现标本的鉴定显示,73.3%属于副白蛉亚属,6.3%属于白蛉亚属,16.2%属于拉鲁蛉属,4.2%属于塞尔根托蛉属。作为人类皮肤利什曼病传播媒介的白蛉最为常见,占73.3%,其次是占8.2%的白蛉。7月和9月捕获的物种数量最多,分别为每诱捕器每晚44.8只和48.7只。这项研究还表明,利什曼病的两个高危月份是7月和9月,因此,有必要在媒介活动期间加强对这种疾病的监测和控制力度。
