Europe is the world's leading tourism destination and is receiving every year travellers from areas with active arbovirus transmission. There is thus a threat of mosquito-borne virus emergence in Europe due to the presence of the invasive mosquito vector Aedes albopictus. Little attention has been paid about the possible role of indigenous mosquito species as vectors of emerging arboviruses. Here, we assessed the vector competence dynamic of Aedes geniculatus, a European anthropophilic mosquito species, for chikungunya virus (CHIKV) in comparison with an European population of Ae. albopictus. We revealed that Ae. geniculatus is highly susceptible to CHIKV infection and could transmit the virus. By specifically exploring the vector competence dynamic in both mosquito species, we revealed that the cumulative distribution of CHIKV incubation period in Ae. geniculatus was delayed by several days as compared to Ae. albopictus. Our results strengthen the importance of considering indigenous species as potential vectors for emerging arboviruses. They also revealed the importance of considering variation in arbovirus dissemination or transmission dynamics in mosquitoes when performing vector competence assays. We will discuss the implications of our results on a CHIKV outbreak dynamic in a theoretical framework.

欧洲本土的伊蚊(Aedes geniculatus)蚊种可以传播基孔肯雅病毒。

欧洲是世界上主要的旅游目的地,并且每年接待来自虫媒病毒活跃传播地区的旅行者。因此,由于侵入性蚊媒伊蚊白纹伊蚊的存在,在欧洲存在由蚊媒传播的病毒的威胁。关于本地蚊子作为新兴虫媒病毒的可能作用的关注很少。在这里,我们与欧洲的Ae种群相比,评估了欧洲的嗜人蚊种-伊蚊(Aedes geniculatus)对基孔肯雅病毒(CHIKV)的载体竞争能力动态。白化病。我们透露了 geniculatus对CHIKV感染高度敏感,可以传播该病毒。通过专门研究两种蚊子的媒介能力动态,我们揭示了CHIKV潜伏期在Ae中的累积分布。与Ae相比,成年ula延迟了几天。白化病。我们的结果加强了将土著物种视为新兴虫媒病毒的潜在载体的重要性。他们还揭示了在进行载体能力分析时,考虑虫媒传播或蚊子传播动力学变化的重要性。我们将在理论框架中讨论我们的结果对CHIKV爆发动态的影响。他们还揭示了在进行载体能力测定时,考虑虫媒传播或蚊虫传播动态变化的重要性。我们将在理论框架中讨论我们的结果对CHIKV爆发动态的影响。他们还揭示了在进行载体能力分析时,考虑虫媒传播或蚊子传播动力学变化的重要性。我们将在理论框架中讨论我们的结果对CHIKV爆发动态的影响。
