尽管亚洲虎蚊（白纹伊蚊）的主动传播能力较低，但其在世界范围内的殖民化速度很快。长期以来，间接证据和非正式报告都暗示汽车是被动交通工具，但由于实时路边调查的困难，以前没有对这一点进行系统研究。在这里，我们报告了第一次抽样研究，证实成年虎蚊与人类一起乘车旅行，并使我们能够估计这些事件的频率。我们将结果与公民科学数据结合起来，在全国范围内模拟白纹伊蚊的汽车传播。2015年夏季，我们在西班牙东北部对770辆汽车进行了采样，发现4只成年雌虎蚊在采样前进入了汽车。我们的贝叶斯模型表明，在巴塞罗那市区每天650万次的汽车出行中，有1.3万至7.15万次有助于虎蚊的活动，巴塞罗那是西班牙省际虎蚊转移的最大来源。我们的研究结果得到了专家验证的公民科学数据的支持，将有助于更好地了解虎蚊的入侵过程，并最终制定更有效的媒介控制策略。
Whereas the Asian tiger mosquito (Aedes albopictus) has low active dispersal capabilities, its worldwide colonization has been rapid. Indirect evidence and informal reports have long implicated passive transportation in cars, but this has not previously been studied systematically given the difficulties of real-time roadside surveys. Here we report the first sampling study confirming that adult tiger mosquitoes travel with humans in cars and enabling us to estimate the frequency of these events. We combine the results with citizen science data to model the car-facilitated dispersal of Aedes albopictus at a nationwide level. During the summer of 2015, we sampled 770 cars in north-eastern Spain, discovering 4 adult female tiger mosquitoes that had entered cars prior to sampling. Our Bayesian model suggests that of the 6.5 million daily car trips in the Barcelona metropolitan area, between 13,000 and 71,500 facilitate tiger mosquito movement, and that Barcelona is the largest source of inter-province tiger mosquito transfers in Spain. Our results are supported by expert-validated citizen science data, and will contribute to better understanding the tiger mosquito’s invasion process and ultimately lead to more effective vector control strategies.
