摘要

尽管库蚊物种被认为同样受到针对疟疾媒介的控制措施的影响,但仍然没有足够的证据表明杀幼虫等干预措施对这些蚊子物种分布的影响。本研究评估了喀麦隆雅温得市一项针对疟疾媒介的杀幼虫试验对库蚊物种的影响。实施了一项比较13个治疗集群和13个未治疗集群的集群随机试验。数据是在2017年3月至2020年11月的基线和杀幼虫干预期间收集的。在干预区域每2周施用一次微生物杀幼虫剂VectoMax G。在干预区和非干预区使用美国疾病控制与预防中心的光捕捉器收集成年蚊子,并在不同的武器之间进行比较。在全球范围内,杀幼虫干预与库蚊幼虫水生栖息地减少69%和室内成年库蚊密度减少36.65%有关。室内(35.26%)和室外(42.37%)的成年库蚊密度都有所降低。库蚊物种组成没有变化。这项研究表明,杀幼虫对库蚊的物种分布有很大影响。如果以包括坑厕在内的典型库蚊繁殖栖息地为目标,干预措施的影响可以得到改善。

Larviciding intervention targeting malaria vectors also affects Culex mosquito distribution in the city of Yaoundé, Cameroon

Larviciding intervention targeting malaria vectors also affects Culex mosquito distribution in the city of Yaoundé, Cameroon

Although Culex species are considered to be equally affected by control measures targeting malaria vectors, there is still not enough evidence of the impact of interventions such as larviciding on the distribution of these mosquito species. The present study assessed the impact of a larviciding trial targeting malaria vectors on Culex mosquito species in the city of Yaoundé, Cameroon. A cluster randomized trial comparing 13 treated clusters and 13 untreated clusters was implemented. Data were collected at baseline and during the larviciding intervention, from March 2017 to November 2020. The microbial larvicide VectoMax G was applied once every 2 weeks in the intervention areas. Adult mosquitoes were collected using CDC light traps in both intervention and non-intervention areas and compared between arms. Globally, larviciding intervention was associated with 69% reduction in aquatic habitats with Culex larvae and 36.65% reduction of adult Culex densities in houses. Adult Culex densities were reduced both indoors (35.26%) and outdoors (42.37%). No change in the composition of Culex species was recorded. The study suggests a high impact of larviciding on Culex mosquito species distribution. The impact of the intervention can be improved if typical Culex breeding habitats including pit latrines are targeted.
