The Ministry of Health informs that eggs of the invasive Asian tiger mosquito Aedes albopictus have been detected near Capellen (Municipality of Mamer) in the week of 17-23 July 2023.

In the next few days, the Luxembourg authorities, with the support of an expert, will assess the situation and take all necessary actions.

The Atlas of the Mosquitoes of Luxembourg has just been published in the Ferrantia series of the National Museum of Natural History and describes 28 species (31 taxa) of culicides found in the Grand Duchy.

Mosquito-borne diseases such as chikungunya, dengue, Usutu or West Nile, have come back to the forefront in both human and animal health. To prevent outbreaks, it is necessary to acquire a solid knowledge of the mosquito fauna in the considered area. Therefore, and since the mosquito fauna of Luxembourg was only partially known, we suggested the construction of the first comprehensive mosquito diversity and distribution database for the Grand Duchy as a base for an atlas. This atlas of the mosquitoes of Luxembourg assembles a taxonomic list and species distribution maps.

The Atlas was developed in the framework of the MosquitoLUX (2019-2022) project implemented under the auspices of the Fondation faune-flore at the Scientific Research Centre of the National Museum of Natural History in Luxembourg. The Fondation faune-flore was the host institution and administrative manager of the project.

The Ministry of Health informs that a population of the invasive Asian tiger mosquito Aedes albopictus has been detected at two locations in the territory of the Commune of Roeser. This first appearance of the tiger mosquito in the Grand Duchy has been confirmed by an international expert in the field. According to current information, this is a limited phenomenon. The tiger mosquito does not move very far and usually does not travel more than a hundred metres from its birthplace.

In the next few days, the Luxembourg authorities, with the support of an expert, will assess the situation, as well as set up a prevention plan and a surveillance and eradication system. The use of insecticides is currently under consideration. However, eradication would be mainly through the elimination of potential habitats.

“On 13 June 2019, in a sample of mosquitoes captured in the province of Flevoland, the Netherlands during routine surveillance, a specimen was recognised as potentially belonging to an exotic species. Based on the molecular analysis of the specimen, we concluded that it belonged to Aedes flavopictus (Yamada, 1921). To our knowledge, this is both the first time that this species has been reported outside its area of origin in north-east Asia and associated with the import of used tyres” (Ibáñez-Justicia et al. 2019).

In June 2019, during the second field work period for the MosquitoLUX project aiming to produce an atlas of the mosquitoes of Luxembourg, two species new to Luxembourg have been found: Culex modestus (an important vector for the West Nile Virus) and Uranotaenia unguiculata. Additionally, Culiseta glaphyroptera  (Schiner, 1864), also a mosquito species new to Luxembourg, was found in the bycatches from 2007 from Dieter Weber in the Museum (Weber 2013). This extends the provisional checklist to 25 species.
