Brief description

CDC-Gathany-Aedes-albopictus-2Aedes albopictus (Skuse, 1895) is a mosquito native to the tropical and subtropical areas of Southeast Asia; however, in the past few decades, this species has spread to many countries through the transport of goods and international travel. It is characterized by the white bands on its legs and body. The first establishment in Europe occurred in 1979 in Albania (Adhami and Reiter 1998), next in 1990 in Genoa, Italy (Sabatini et al. 1990).

This mosquito has become a significant pest in many communities because it closely associates with humans (rather than living in wetlands), and typically flies and feeds in the daytime in addition to at dusk and dawn. The insect is called a tiger mosquito for its striped appearance, which resembles that of the tiger. Ae. albopictus is an epidemiologically important vector for the transmission of many viral pathogens, including the yellow fever virus, dengue fever, and Chikungunya fever, as well as several filarial nematodes such as Dirofilaria immitis. Aedes albopictus is capable of hosting the Zika virus and is considered a potential vector for Zika transmission among humans (Wikipedia contributors 2020).


Potential breeding site for the Asian tiger mosquito.

Invasions of the Asian tiger mosquito into new areas of its potential range are often initiated through the transportation of eggs via the international trade in used tires (due to the rainwater retained in the tires when stored outside).

Status and distribution in Luxembourg

On on 2022-09-03, the Luxembourg Ministry of Health informs that a population of the tiger mosquito “Aedes albopictus” has been detected at two locations in the territory of the Commune of Roeser.

On on 2023-07-31, the Luxembourg Ministry of Health informs that eggs of the tiger mosquito “Aedes albopictus” have been detected near Capellen (Municipality of Mamer) in the week of 17-23 July 2023. This is the second detection of the invasive Asian tiger mosquito Aedes albopictus in Luxembourg.

Until September 2022 there was no documented occurrence of Aedes albopictus (Skuse, 1895) in Luxembourg yet (MNHNL, iNaturalist & GBIF 2021). The species has established itself in Alsace (France) and in Oestrich-Winkel near Mainz (Germany), about 150 km from the borders of Luxembourg. The species is regularly introduced into our neighbouring regions (Belgium and Holland, Lorraine, Rhineland-Palatinate) but is not yet established there thanks to monitoring and treatment of sites. An egg clutch was observed in August 2018 on a motorway rest area near Arlon (Belgium). Immediate site treatment prevented the development of a local population.

As of 2021, we estimated the arrival of the species in Luxembourg to be imminent.

The map shows the current known distribution of Aedes albopictus in Europe at at ‘regional’ administrative level (NUTS3), as of March 2021 (ECDC & EFSA, 2021).

From May to November, 2020, five ovitraps have been placed on the motorway service areas “Aire de Berchem (Est)” and “Aire de Capellen (Nord)” in order to survey the invasive Asian tiger mosquito Aedes albopictus. Both highways A3 and A6 are considered to be putative mosquito hitchhikers’ entry pathways into Luxembourg. The traps have been monitored over 23 weeks producing a total of 80 data. No mosquito eggs could be found in any sample. This surveillance was carried out as part of the international AIMSurv2020 project in the frame of the EU COST action CA17108 “Aedes Invasive Mosquitoes” (Ries & Schaffner 2020).

In 2016, the National Natural History Museum carried out a survey on mosquito species in Luxembourg. In July and August, ten mosquito traps were installed in different locations throughout the country. The BG-Sentinel 2 traps from the company Biogents were run for 24 hours once every week until the end of October. The catch was preserved in deep freezers and transferred to the Museum for identification. The catch was identified by mosquito specialist Dr. Francis Schaffner, University of Zurich. No invasive species were found among the caught specimens (Ries et al. 2019).

A public petition (n°1071) for a public health policy that effectively combats the implantation of tiger mosquitoes, vectors of diseases, in Luxembourg, was introduced on 10th July 2018 and was open for signatures until 19th September 2018 (Sarno Bomfim 2018).

Risk assessment

ISEIA protocol

C1 (2+3+1+1), reassessed on 3rd September 2022 by C. Ries. Originally assessed C0 (2+3+1+1) (Ries et al. 2017: 68).

Harmonia+ protocol

Overall risk score 0,27 = (Overall Invasion score 0,47 x Overall Impact score 0,58) (Schaffner & Ries 2019: 178).
