BACKGROUND
Aedes koreicus is a mosquito species characterized by marked anthropophilic behavior, and a potential vector of nematodes and viruses. It is native to East Asia, but its presence has recently been reported in many regions of Europe. In Italy, these mosquitoes had been detected in the northeast since 2011 and are now spreading towards the southwest of the country.
METHODS
In 2020, during a surveillance program for invasive mosquito species in the district of Bergamo (Lombardy Region, Italy), about 6000 mosquito larvae were collected. Emerged adults were assigned to mosquito species according to morphological analyses, followed by amplification and sequencing of genetic markers (COI, ND4, ITS2 and D2).
RESULTS
According to the morphological and genetic data, about 50 individuals belonged to the species Ae. koreicus.
CONCLUSION
We report the presence of Ae. koreicus in the district of Bergamo, which confirms the spread of this species in the north of Italy and raises concerns about its possible role as a vector of diseases in the Alpine area.
背景
白纹伊蚊是一种具有明显嗜人习性的蚊子，也是线虫和病毒的潜在传播媒介。它原产于东亚，但最近在欧洲许多地区都有发现。在意大利，这些蚊子自 2011 年以来一直在东北部被检测到，现在正在向该国西南部蔓延。
方法
2020 年，在贝加莫（伦巴第大区，意大利）地区入侵性蚊子物种监测计划期间，共收集了约 6000 只蚊子幼虫。出现的成虫根据形态分析被分配到蚊子种类，然后对遗传标记（COI、ND4、ITS2 和 D2）进行扩增和测序。
结果
根据形态学和遗传学数据，约有 50 只个体属于白纹伊蚊。
结论
我们报告了在贝加莫地区存在白纹伊蚊，这证实了该物种在意大利北部的传播，并引起了对其在阿尔卑斯地区可能作为疾病传播媒介的担忧。
