First detection of the invasive Asian tiger mosquito Aedes albopictus in Luxembourg

CDC-Gathany-Aedes-albopictus-2The 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.

Detection of Aedes flavopictus in the Netherlands

“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 (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).

Three mosquito species new to Luxembourg: Culex modestus, Uranotaenia unguiculata and Culiseta glaphyroptera

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.
