Update on the situation of Anoplophora glabripennis in Germany

In Germany, the first outbreak of Anoplophora glabripennis (Coleoptera: Cerambycidae - EPPO A1 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, Nordrhein-Westfalen, Sachsen-Anhalt. Eradication measures have been applied in all cases, in line with EU Implementing Decision 2015/893/EU and the German guidelines ‘Leitlinie zur Bekämpfung des Asiatischen Laubholzbockkäfers Anoplophora glabripennis’. Surveillance includes monitoring of host plants twice a year, pheromone traps and use of sniffer dogs. The NPPO of Germany recently declared the eradication of several outbreaks and updated the situation of others:

  • Baden Württemberg: the region is now free from A. glabripennis
    • the outbreak in Grenzach-Wyhlen, detected in 2011, is considered eradicated as no signs of the pest has been detected in 2015-2019.
    • the outbreak in Hildrizhausen is considered eradicated. It had been detected in 2016: in total 20 infested trees and 15 adult beetles were found. In the period 2017-2020, no sign of the pest has been detected.

  • Bavaria
    • the following outbreaks are declared eradicated as no sign of the pest has been detected for the last four years: Feldkirchen (detected in 2012, RS 2013/138), Neubiberg (detected in 2014), Kelheim (detected in 2016, RS 2016-116) and Murnau (detected in 2016 RS 2017/006).
    • the outbreak in Ziemetshausen, near Augsburg, detected in 2014 (RS 2014/184) covered 66.6 ha in 2016 and 118 trees and shrubs were found to be infested since the initial finding. One female was caught in a pheromone trap in 2018 but no infested trees have been found in 2017-2020. Monitoring will continue at least until December 2022.
    • a new outbreak was detected in August 2019 in Miesbach. Surveys conducted in 2019 detected 34 infested plants in the genera Acer, Betula and Aesculus. Eradication carries on.

  • Nordrhein-Westfalen

An outbreak had been detected in 2005 in a commercial zone in the municipality of Bornheim (RS 2008/095). Further infested trees (only Acer spp.) were found as a result of the official survey in Bornheim-Hersel in November 2007; then in August 2009 in the municipality of Alfter (within the demarcated area), in May 2010 in Bornheim-Roisdorf, and in 2012 in a school yard in Bonn-Tannenbusch. The demarcated area was therefore extended from 2900 to 3096 ha. In the period 2005-2012, 40 infested trees have been detected during official surveys in the demarcated area, and 1432 trees have been destroyed as a precautionary measure. Since 2012, only 2 infested trees have been detected (one in 2015, and one in 2017). Based on the survey results, it is expected that eradication of A. glabripennis in the demarcated area could be achieved in the near future.

  • Sachsen-Anhalt

An outbreak was detected in 2014 in Madgdeburg (RS 2014/184). A demarcated area was established. From April 2015 to March 2016, 18 infested plants were detected in the quarantine area, from April 2016 to March 2017, 12 (Salix spp., Acer spp., Populus spp.), from April 2017 to March 2018, 1 (Populus sp.), from April 2019 to March 2020, 15 (mainly Acer sppbut also some Fraxinus spp.). Eradication measures continue. In 2020, the demarcated area covered 60.8 km2.

The pest status of Anoplophora glabripennis in Germany is officially declared as: Transient, actionable, under eradication.
