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

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.

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).

The Asian tiger mosquito is spread via the international tyre trade (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

There is no documented occurrence of Aedes albopictus (Skuse, 1895) in Luxembourg yet (MNHNL, iNaturalist & GBIF 2020). The species has established itself near Heidelberg (Germany), Limburg (Netherlands), Strasbourg and Reims (France), less than 200 km from Luxembourg. An egg clutch was observed in August 2018 on a motorway rest area near Arlon (Belgium) and we estimate that the species could arrive in Luxembourg around 2019-2020.

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.

In June 2017, the catch was identified with mosquito specialist Dr. Francis Schaffner from the University of Zurich. No invasive species were found among the caught specimens.

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).
