Update on the situation of Anoplophora glabripennis in Germany
In Germany, the first outbreak of Anoplophora glabripennis (Coleoptera: Cerambycidae - EPPO A2 list) was detected in Bavaria in 2004 (EPPO RS 2004/072). Since then, other outbreaks have been detected in Bavaria, as well as in Baden Württemberg (now eradicated), Nordrhein-Westfalen, and Sachsen-Anhalt. Eradication measures have been applied in all cases. The NPPO of Germany recently declared the eradication of several outbreaks and updated the situation of others:
- Bavaria
The outbreak in Ziemetshausen, near Augsburg, first detected in 2014 (RS 2014/184, RS 2021/058) is considered eradicated since November 2022. No signs of A. glabripennis were found in the years from 2019 to 2022.
- Nordrhein-Westfalen: the region is now free from A. glabripennis
An outbreak had been detected in 2005 in a commercial zone in the municipality of Bornheim (EPPO RS 2008/095) and then in neighbouring areas. A demarcated area was established. The last finding of A. glabripennis occurred in 2017. In 2017-2021 the demarcated area was intensively investigated and no A. glabripennis has been found since 2017. The outbreak is considered eradicated since November 2021.
- Sachsen-Anhalt
An outbreak was detected in 2014 in Madgdeburg (EPPO RS 2014/184, 2021/058). In 2020, 15 trees were felled and destroyed. Only Acer trees were found to be infested. In addition, 2 specimens were caught in traps. From December 2020 to September 2022, 6 infested trees were found (1 Acer sp.; 3 Salix sp. and 2 Populus sp.). In August 2021, one female was caught in a pheromone trap within the demarcated area. The trap was located 172 m west of the last findings made in March 2020. Additional survey activities have been initiated immediately in that area. In August 2022 and in September 2022, a female was caught in a pheromone trap within the demarcated area.
