Abstract: Range expansion of the alien mosquito species Aedes japonicus
(Theobald, 1901) (Di ptera: Culicidae) from 2014  2019 in Burgenland, Austria. In
the last 30 years, various Aedes species were introduced outside their native range.
The potentially invasive mosquito species Ae. japonicus was recorded in Europe
in 2000 and was found for the first time in Austria in 2011. Within the scope of a
mosquito-monitoring program (2014 2019) the range expansion of Ae. japonicus in the
province of Burgenland (Austria) was investigated. Throughout the sampling period
130 female Ae. japonicus were collected. The first specimens were captured in 2014
in the southernmost sampling sites. In the following years this species increased its
range northwards, on average covering 13.6 km/year (sd=20.87). In 2019, its northernmost
distribution was in the district Mattersburg, which is located 67.9 km north of the
northernmost distribution in 2014 (Gu&776;ssing). Adults of Ae. japonicus were captured
from May to November, with the highest numbers trapped in July and August. The
continuative range expansion of this species from the south to the north suggests
that this process is driven by natural factors like active dispersal or wind. We found
Ae. japonicus not to be very abundant but common in Burgenland. At present, there
is no proof that Ae. japonicus is invasive in Austria. More in-depth and long-term
investigations of Ae. japonicus are necessary to investigate their interactions with
autochthonous species to assess whether this species can become invasive.
