SUMMARY METHODS: Mosquito aquatic stages were collected in domestic and peri-domestic areas, and epidemic risk indexes (Breteau, Container) were calculated for each prospected location. Adult female mosquitoes were captured by human landing catches, while larvae were sampled by inspecting artificial and natural breeding sites in randomly selected premises.
Seventy-eight adults Aedes albopictus were collected in Bangui and Bayanga. Mosquito biting rate and abundance were, respectively, 0.33-1.70 bites/human/hour and 14.6% in Bangui and 0.04-0.16 and 0.4% in Bayanga. Larval sampling revealed a large diversity of water container harbouring the species in Bangui, Bayanga, Nola and Salo including unused containers, old tires, vehicle carcasses, buckets, barrels and stem of bamboo. The epidemic risk indices were erratic according to the location, ranging between 1.5-27.6 for Breteau and 1.3-47.1 for Container.
This is the first record of Ae. albopictus in two bioclimatic zones of CAR This observation emphasizes the need to further investigate its potential impact on dengue and chikungunya viruses transmission regarding their recent emergencies in Africa (Côte d'Ivoire, Senegal, Mali, Somalia, Gabon, Cape Verde Islands).
摘要方法：在家庭和周边地区收集蚊虫的水生阶段，并为每个预期地点计算流行风险指数（布雷托、容器）。通过人类降落捕捉捕获成年雌性蚊子，而幼虫则通过检查随机选择的场所中的人工和自然繁殖地进行采样。
在班吉和巴扬加共收集到 78 只白纹伊蚊成虫。在班吉，蚊虫叮咬率和数量分别为 0.33-1.70 次/人/小时和 14.6%，在巴扬加，蚊虫叮咬率和数量分别为 0.04-0.16 次/人/小时和 0.4%。幼虫采样显示在班吉、巴扬加、诺拉和萨洛有大量不同种类的容器中存在该物种，包括未使用的容器、旧轮胎、车辆残骸、水桶、桶和竹茎。根据地点的不同，布雷托指数在 1.5-27.6 之间波动，容器指数在 1.3-47.1 之间波动。
这是在中非共和国两个生物气候带首次记录到白纹伊蚊。这一观察结果强调需要进一步调查其对登革热和基孔肯雅热病毒传播的潜在影响，因为这些病毒最近在非洲（科特迪瓦、塞内加尔、马里、索马里、加蓬、佛得角群岛）爆发。
