France warns against influx of Japanese beetles that can decimate ecosystems
A number of French departements across the east of the country have warned against the risk of an invasion of the highly destructive Japanese beetle following the detection of several outbreaks of the pest in Switzerland.
Classified as a "priority quarantine pest" within the European Union, the Japanese beetle attacks several hundred species of food, forest and ornamental plants – including vines, fruit trees and lawns.
The warning comes as a significant population of Japanese beetles was detected on 20 June in Switzerland near the city of Basel.
The Swiss authorities discovered a second infestation some 3 kilometres from the French border.
As the harmful beetle is approaching French territory, alerts were issued by the Doubs and Haut-Rhin departments in particular, following a notification on 21 June from the Ministry of Agriculture and Food Sovereignty to raise awareness of the risk to crops and plantations and the potential impact on the economy.
Posting on X, the French Agency for Food, Environmental and Occupational Health and Safety, ANSES, explained: "The Japanese beetle is a plant pest already present in Italy and Switzerland. It is highly likely to enter France, and environmental conditions are favourable".
Traps set across Alsace
Originally from Asia, this plant-eating beetle first established itself in the United States and then in Europe.
It has been present in Italy since 2014 and in Switzerland since 2017.
