亚洲虎蚊（Aedes albopictus）于20世纪80年代抵达美国，并在十年内迅速蔓延到美国东部。预测的美国东海岸越冬分布的北方边缘大致福尔斯横跨纽约、康涅狄格州和马萨诸塞州，早在2000年就有该物种的记录。目前还不清楚是否是Ae。白纹伊蚊种群已经在这些地区建立并在寒冷的冬天存活下来，或者每年都被繁殖。我们对Ae.使用15个微卫星标记对来自美国东北部的白纹伊蚊进行了研究，并将其与全国其他种群以及全球主要遗传分支的代表进行了比较，以研究其连通性和稳定性。在埃厄河北方山脉，很少出现创始人效应或瓶颈。白纹伊蚊分布在美国东北部，种群沿着东海岸具有高水平的遗传多样性和连通性。没有证据表明，在连续三年的过程中，在康涅狄格州的人口流动，在整个这一时期的遗传结构一致。总的来说，这些结果支持的存在，建立人口的Ae。白纹伊蚊在纽约、康涅狄格州和马萨诸塞州成功越冬并大量迁徙。考虑到这些人口的稳定性和相互联系，Ae。在气候变化的平均变暖条件下，白纹伊蚊有可能继续向北扩散和扩大其活动范围。努力控制Ae。因此，这些地区的白纹伊蚊应侧重于病媒抑制而不是根除战略，因为当地种群已经稳固，预计每年夏天都会重新出现。
The Asian tiger mosquito (Aedes albopictus) arrived in the USA in the 1980’s and rapidly spread throughout eastern USA within a decade. The predicted northern edge of its overwintering distribution on the East Coast of the USA roughly falls across New York, Connecticut, and Massachusetts, where the species has been recorded as early as 2000. It is unclear whether Ae. albopictus populations have become established and survive the cold winters in these areas or are recolonized every year. We genotyped and analyzed populations of Ae. albopictus from the northeast USA using 15 microsatellite markers and compared them with other populations across the country and to representatives of the major global genetic clades to investigate their connectivity and stability. Founder effects or bottlenecks were rare at the northern range of the Ae. albopictus distribution in the northeastern USA, with populations displaying high levels of genetic diversity and connectivity along the East Coast. There is no evidence of population turnover in Connecticut during the course of three consecutive years, with consistent genetic structure throughout this period. Overall, these results support the presence of established populations of Ae. albopictus in New York, Connecticut, and Massachusetts, successfully overwintering and migrating in large numbers. Given the stability and interconnectedness of these populations, Ae. albopictus has the potential to continue to proliferate and expand its range northward under mean warming conditions of climate change. Efforts to control Ae. albopictus in these areas should thus focus on vector suppression rather than eradication strategies, as local populations have become firmly established and are expected to reemerge every summer.
