Anoplophora glabripennis detected again in Germany
The NPPO of Germany recently informed the EPPO Secretariat of a new finding of Anoplophora glabripennis (Coleoptera: Cerambycidae – EPPO A1 List) in Bayern (see also EPPO RS 2016/031, 2014/184). In April 2016, during a visual inspection targeting wood packaging material (carrying stones) in the harbour of Kelheim, bore holes and wood shavings were noticed by a phytosanitary inspector on a nearby maple (Acer sp.) tree. Further investigations were carried out and living larvae of A. glabripennis were found in 6 maple trees. These trees were heavily infested and had dead branches (some of these had already broken off). The identity of the pest has been confirmed by PCR. In addition, 12 other maple trees showing signs of infestation (e.g. bore holes, shavings and oviposition sites) were found and will be subject to further studies in the laboratory. The origin of this infestation is unknown but import of infested wood packing material is the most likely pathway. An intensive monitoring of all host plants (i.e. Acer, Alnus, Betula, Corylus, Fraxinus, Populus, Prunus, Salix, Sorbus, Tilia, Ulmus) located within a radius of 500 m around the infested site is being conducted. Eradication measures are being taken and all infested trees (18 in total) have been felled.
The pest status of Anoplophora glabripennis in Germany is officially declared as: Transient, only at some locations, actionable, under eradication.
