Update on the situation of Anoplophora glabripennis in Switzerland
In Switzerland, Anoplophora glabripennis (Coleoptera: Cerambycidae – EPPO A2 List) had been declared eradicated from the country in December 2019 (EPPO RS 2020/005). However, an outbreak was recorded in the municipality of Zell (Canton of Luzern) in August 2022 (EPPO RS 2022/186). This is still under eradication.
The NPPO of Switzerland recently informed the EPPO Secretariat of a new outbreak of A. glabripennis in Marly (Canton of Freiburg). In October 2024, a private citizen reported seeing a live female adult whilst pruning maple (Acer sp.) and walnut (Juglans regia) trees. A survey on the same day confirmed the presence of A. glabripennis. Further surveys in the same area conducted in late October discovered one infested maple tree with a female adult specimen and twenty oviposition sites. The infested tree was immediately felled. The area has been demarcated and further surveys are being conducted to investigate the extent of the outbreak, including the use of sniffer dogs.
The pest status of Anoplophora glabripennis in Switzerland is declared as: Present, only in some parts of the country, under eradication.
