Brief description

Harmonia axyridis (Pallas, 1773) lives in a very wide range of habitats: farmlands, orchards, wetlands, and forest margins. It seems to avoid deep forest habitats. H. axyridis is a strong intraguild predator and is able to displace native ladybird species, hence the population collapse of the two-spot ladybird Adalia bipunctata is largely attributable to its rapid expansion in North America and Europe. The Harlequin ladybird is also known to invade houses in winter (Adriaens et al. 2007).

Status and distribution in Luxembourg

Harmonia axyridis (Pallas, 1773) was observed in Luxembourg for the first time on 18th September 2004 by Nico Schneider at Schleifmillen, municipality of Junglinster (Schneider & Loomans 2006).

196 observations are documented in the mdata.mnhn.lu portal (MNHNL, iNaturalist & GBIF, 2020).

Brief description

Graphocephala fennahi D.A. Young, 1977 is a species of leafhopper native to the United States. Its common name derives from it feeding on the sap of rhododendrons. The species was introduced to Great Britain in the 1930s and continental Europe in the 1970s. There has been suggestion that the rhododendron leafhopper contributes to the spread of a rhododendron fungus through Europe (Wikipedia contributors 2020).

Status and distribution in Luxembourg

In Luxembourg, Graphocephala fennahi D.A. Young, 1977 has been first recorded on 1st January 1999 in Aarnescht, municipality of Niederanven.

10 occurrences of the species are documented in the MNHNL-mdata portal ranging from 1999 to 2014 (MNHNL, iNaturalist & GBIF 2020).

Brief description

Drosophila suzukii (Matsumura, 1931) is a fruit crop pest and can be a serious economic threat to soft summer fruit.

The cherry vinegar fly is known as a pest in fruit and wine growing. A study in the cantons of Zug and Zurich now shows that the forest is also affected by this invasive alien insect. The heavy infestation of wild fruits reduces the food basis of many animal species and the spread of the affected plant species (Bühlmann et al. 2021).

Status and distribution in Luxembourg

Drosophila suzukii (Matsumura, 1931) first appeared in Luxembourg in 2014 which raised great attention (Nonet 2014; Schultz & Molitor 2016). A large-scale monitoring of the spotted-wing drosophila was carried out in the Moselle region in 2016 in cooperation with the Luxembourg Institute of Science and Technology (LIST).

No records are available through the mdata.mnhn.lu portal (MNHNL, iNaturalist & GBIF 2020).

Brief description

Cydalima perspectalis (Walker, 1859) is a species of moth of the family Crambidae. It is native to eastern Asia (Japan, China, Taiwan, Korea, the Russian Far East and India), where the caterpillars feed on Buxus microphylla without causing any damage. It is an invasive species in Europe, first recorded in Germany in 2006, and subsequently in Switzerland and the Netherlands in 2007, Great Britain in 2008, France and Austria in 2009, Hungary in 2011, Romania, Spain and Turkey. It is also known from Slovakia, Belgium and Croatia, and in 2016 in Bosnia and Hercegovina. During the preparation for the 2014 Olympics, in 2012 it was introduced from Italy to Sochi with the planting stock of Buxus sempervirens and during the next year it began to defoliate Buxus colchica in large quantities.

The larvae feed on the leaves and shoots of Buxus species. Young larvae only eat the upper part of the leaf, leaving the hardest inside structure. The leaves are not destroyed completely but appear as “peeled” in small parallel beats lines, or almost completely. These peeled leaves eventually die. Old larvae are the most damaging: they massively and completely eat the leaves, sometimes leaving a thin part at the contour and centre of the leaf, however. Green ball-shaped frass can usually be seen on host plants (Wikipedia contributors 2020).

Status and distribution in Luxembourg

In Luxembourg, Cydalima perspectalis (Walker, 1859) was first observed on 11th September 2015 by Svenja Christian in Wasserbillig, municipality of Mertert (Hellers & Christian 2016). In 2016, the moth was observed in Dudelange by Georges Bechet. Since then, the species has spread massively and can be found virtually all over the country. Reports are less frequent in the North of Luxembourg.

Brief description

Corythucha ciliata Say, 1832 is a species of lace bug in the family Tingidae that is associated with sycamore trees. It originates in the New World, but has been introduced and has spread in Europe. It is a small, whitish insect and feeds on the underside of the leaves, sucking sap. In Europe, C. ciliata was first observed in 1964 in Padova, Italy, and has since spread throughout Southern and Central Europe, infesting the European hybrid plane (Platanus × acerifolia). Although it does not of itself kill trees, in Central Europe it is often found in association with two plant-pathogenic fungi which can kill trees, Apiognomonia veneta and Ceratocystis fimbriata, leading to the hypothesis that it may act as a vector for these fungi (Wikipedia contributors 2019).

Status and distribution in Luxembourg

Corythucha ciliata Say, 1832 is considered widespread in Luxembourg. The sycamore lace bug was first observed in Luxembourg by Svenja Christian in 2010 in Wasserbillig. Schneider & Christian (2013) list 14 localities where the species occurred in 2012, while 17 observations are documented in the mdata.mnhn.lu portal (MNHNL, iNaturalist & GBIF 2020).

Brief description

Cameraria ohridella Deschka & Dimić, 1986 is a leaf-mining moth of the family Gracillariidae. The horse-chestnut leaf miner was first observed in North Macedonia in 1984, and was described as a new species in 1986. Its larvae are leaf miners on the common horse-chestnut (Aesculus hippocastanum). The horse-chestnut leafminer was first collected and inadvertently pressed in herbarium sheets by the botanist Theodor von Heldreich in central Greece in 1879. Cameraria ohridella causes significant damage, mainly late summer browning, to the appearance of horse-chestnut trees. Despite the poor appearance of these infested trees, there is no evidence that damage by the moth leads to tree death. Although horse-chestnut occurs naturally mostly above the 700–1000 m. contours the moth does well in well-watered places such as parks in cities and at low elevation but not well in the hotter parts of Europe e.g. Spain. Probably aided greatly by vehicular transport, the moth has attained a very rapid dispersal rate across Europe of 60 km per year (Wikipedia contributors 2020).

Status and distribution in Luxembourg

Nico Schneider observed and documented occurrences of Cameraria ohridella Deschka & Dimić, 1986 in 2003 in Luxembourg-Limpertsberg (Schneider 2003).

15 records of the horse-chestnut leaf miner are listed in the mdata.mnhn.lu portal ranging from 2007 to 2017 (MNHNL, iNaturalist & GBIF 2020).

Brief description

Anoplophora glabripennis (Motschulsky, 1853) is native to eastern China, and Korea. The Asian long-horned beetle has now been accidentally introduced into the United States, where it was first discovered in 1996, as well as Canada, and several countries in Europe, including Austria, France, Germany, Italy and UK. This beetle is believed to have been spread from Asia in solid wood packaging material. Due to high tree mortality caused by larval feeding outside its native range, A. glabripennis can change both forest and urban ecosystems. In the United States, it can potentially destroy 30.3% of urban trees and cause $669 billion in economic loss. Early detection is used to manage infestations before they can spread (Wikipedia contributors 2020).

Brief description

Aedes 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).

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).

Advice for the population

Please refer to the Internet page https://mosquitoes.lu/dealing-with-mosquitoes/ for detailed information in 5 languages (  ) on how to deal with mosquitoes near your home.

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.

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).

Brief description

Faxonius limosus Rafinesque 1817 (Synonyme Orconectes limosus Rafinesque 1817) is native to the east coast of North America. It is unusual in that it lives in silty streams, rather than the clear water usually preferred by crayfish. Like Pacifastacus leniusculus, another invasive North American crayfish, O. limosus carries crayfish plague and is a threat to native European crayfish. The spinycheek crayfish was introduced to Germany in 1890, and has since spread across much of Northern Europe, recently reaching the United Kingdom. It has also spread southwards as far as the Danube in Serbia. These Crayfish live on the bottom of the freshwater pools, such as lakes, ponds and swamps. They prefer flat, sandy, and rocky floors. They are also found outside the water on beaches or lawns near the pool of water. They use rocks to make burrows while in the water (Wikipedia contributors 2019).

Faxonius limosus is omnivorous and, being able to reach high densities, can impact native macroinvertebrates and macrophytes (CABI 2019).

IAS of Union concern

In 2016, Faxonius limosus Rafinesque 1817 was added to the list of invasive alien species of Union concern (Anonymous 2016) which implies that member states shall take all necessary steps to prevent it’s unintentional introduction or spread.

Status and distribution in Luxembourg

Faxonius limosus Rafinesque 1817 was first documented in Luxembourg in 1978 in the river Moselle near Wasserbillig, municipality of Mertert (Neitzke 1978 cit. in Dhur & Massard 1995: 144). Atten (1987) located the immigrant in several places in Moselle (Schengen, Remich), Duhr (1993) downstream of Stadtbredimus, in the Remerschen ponds and in the lower reaches of the Sûre (cit. in Duhr & Massard 1995: 144 & 147).

It is no longer possible to eliminate the spinycheek crayfish populations present (Troschel 2010: 202, Troschel & Bartl 1998: 146).

Management

Action plan

An action plan regarding the management of Faxonius limosus (and Pacifastacus leniusculus) has been published in 2020:
