The invasive species Aedes (Finlaya) koreicus was first identified in north-eastern Italy in 2011, during the ongoing surveillance activity of Aedes albopictus. Following this finding, a more intensive monitoring was carried out to assess the distribution of the species and to collect biological data. Herein, we report the new records obtained by four years of surveillance.
The presence of Ae. koreicus was checked using ovitraps, adults traps and by larval collections in all possible breeding sites from May 2011 to July 2015. The monitoring started in the site of the first detection (Province of Belluno) and was then extended in the neighbouring Provinces belonging to four Regions. Aedes koreicus was found in 73 municipalities out of 155 monitored (47.1 %), including 23 municipalities (14.8 %) previously not infested. The area of first detection of Ae. koreicus (Province of Belluno) was also the most infested (68 %). However the mosquito has also been found to the west (Province of Trento) and to the south and south-west (Provinces of Vicenza and Treviso) of the initially infested area.
The spread of Ae. koreicus is directed towards south and west from the original infested area, likely due to the dense road connections and the habitat suitability of the new areas. According to these records, northern Italy has a high probability to be invaded by Ae. koreicus in the next decade. These data can be useful to validate predictive models of potential distribution and dispersal of this species in Italy or in Europe.
入侵物种白纹伊蚊（Finlaya）朝鲜伊蚊于2011年在意大利东北部被首次发现，当时正在对白纹伊蚊进行持续监测活动。这一发现之后，开展了更密集的监测以评估该物种的分布并收集生物学数据。在此，我们报告四年监测所获得的新记录。
2011年5月至2015年7月期间，使用诱蚊产卵器、成蚊诱捕器并通过在所有可能的繁殖地收集幼虫来检查朝鲜伊蚊的存在情况。监测始于首次发现的地点（贝卢诺省），随后扩展到属于四个大区的邻近省份。在155个受监测的市镇中，有73个市镇发现了朝鲜伊蚊（47.1%），其中包括23个之前未受侵扰的市镇（14.8%）。朝鲜伊蚊首次被发现的地区（贝卢诺省）也是受侵扰最严重的地区（68%）。然而，在最初受侵扰地区的西部（特伦托省）以及南部和西南部（维琴察省和特雷维索省）也发现了这种蚊子。
朝鲜伊蚊正从最初受侵扰地区向南和向西扩散，这可能是由于密集的道路连接以及新区域适宜的栖息地。根据这些记录，意大利北部在未来十年很有可能被朝鲜伊蚊入侵。这些数据有助于验证该物种在意大利或欧洲潜在分布和扩散的预测模型。
