Brief description

Leptinotarsa decemlineata Say, 1824 is a major pest of potato crops. It is approximately 10 millimetres long, with a bright yellow/orange body and five bold brown stripes along the length of each of its elytra. Native to America, it spread rapidly in potato crops across America and then Europe from 1859 onwards. The Colorado beetle has a strong association with plants in the family Solanaceae, particularly those of the genus Solanum e.g.: Solanum nigrum (black nightshade), Solanum melongena (eggplant or aubergine), Solanum dulcamara (bittersweet nightshade), Solanum tuberosum (potato),  Solanum lycopersicum (tomato) and the genus Capsicum (pepper) (Wikipedia contributors 2020).

Status and distribution in Luxembourg

Leptinotarsa decemlineata Say, 1824 was first reported on 23rd June 1936 in Steinsel-Müllendorf, then in Limpertsberg, Mamer and Neuhäuschen in the same year. In 1937 it was reported from Eischen, Finsterthal and Beyren. By 1938 the whole country was infested. The details of this invasion were published by Jos Massard (2000).

The distribution of the species is still widespread all over the country, but populations have sharply decreased, particularly due to the decline of potato production, e.g. from >17000 ha in 1939 to 800 in 1995 (Massard 2000: 212).

Only 14 occurrences of the species are documented in the mdata.mnhn.lu portal, ranging from 1968 to 2019 (MNHNL, iNaturalist & GBIF 2020).

Brief description

Lasius neglectus Van Loon, Boomsma & Andrásfalvy, 1990 is a polygynous, sometimes invasive, ant of the genus Lasius. The ant was identified in 1990 after establishing a colony in Budapest, Hungary. Superficially, they are similar in appearance to the common black garden ant, Lasius niger, but have significantly different behavioural patterns, particularly in the social structure within colonies. Lasius neglectus is believed to be prey for several animals and insects, specifically Clytra laeviuscula and some Picidae family birds.

Lasius neglectus can outnumber native European varieties of ant by 10 to 100 times in infested gardens and, as such, has been considered a pest in many central European countries. The species has spread as far as Jena in Germany, Ghent in Belgium and Warsaw in Poland. A colony has been reported in Hidcote Bartrim, Gloucestershire in England, where it demonstrates an affinity for outdoor electrical fittings where it may constitute a fire risk (Wikipedia contributors 2020).

Brief description

Hyphantria cunea (Drury, 1773), native to North America, is a moth in the family Erebidae known principally for its larval stage, which creates the characteristic webbed nests on the tree limbs of a wide variety of hardwoods in the late summer and fall. It is considered a pest but although unsightly, does not harm otherwise healthy trees. It is well known to commercial tree services and arboriculturists. The adult fall webworm has a wingspan of approximately 30 mm and is generally white-colored, although some individuals may have dark-colored marks (Wikipedia contributors 2020).

Status and distribution in Luxembourg

So far, Hyphantria cunea (Drury, 1773) has been documented only once, in 2014 in the Kirchberg district in Luxembourg City (Source ?).

There is no distribution map available because no data has been entered into the Recorder-Lux database so far (MNHNL, iNaturalist & GBIF 2020).

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.

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).

Status and distribution in Luxembourg

There is no documented observation of Anoplophora glabripennis (Motschulsky, 1853) in Luxembourg yet (MNHNL, iNaturalist & GBIF 2020).
