An exotic mosquito originating from Japan has been spotted in Luxembourg, according to the department of health.
According to a press release published on Tuesday, the first sighting of “Aedes japonicus” was made on private property in Stolzembourg, close to Vianden and on the German border on Monday. Tests conducted by the national museum of natural history confirmed the identity of species.
The large dark brown mosquito (10-12 mm) with characteristic white spots on the legs and along the abdomen, and 5 gold longitudinal bands on the thorax is an invasive insect native to Asia. Similar sightings have been made in the province of Namur (Belgium), North Rhine-Westphalia and Hesse (Germany), and in Bas-Rhin, Haut-Rhin and Vosges (France).
Authorities along with a Swiss expert will assess the situation and in the coming days introduce a monitoring and extermination system without the use of insecticides. According to the press release, “Aedes japonicus” moves little and generally does not travel more than a few dozen metres from its birthplace.
According to the European Centre for Disease Prevention and Control, the Japanese mosquito is the “third invasive mosquito species to be reported in Europe” since its first sighting in 2000. It further said the insect’s expansion was facilitated by international human activities including the trade in used tyres. It is also listed as one of the top 100 invasive species by the Invasive Species Specialist Group.
