Situation of Anoplophora glabripennis in Austria in 2008
In Austria, Anoplophora glabripennis (Coleoptera: Cerambycidae – EPPO A1 List) was first detected in 2001 in the city of Braunau am Inn (EPPO RS 2001/215). It is assumed that the pest was introduced with wood packaging material, dumped near a store. In 2001, 89 beetles were caught, and 38 trees were found infested and destroyed. Since 2001, all potential host plants have been annually inspected across the whole area of Braunau and eradication measures have been implemented. All infested trees were immediately felled, chipped and incinerated. As a result, the number of infested trees was considerably reduced from 38 in 2001, to 7 in 2006. However, in spring 2007 a new outbreak was detected in the eastern part of the industrial zone of Braunau, and by April 2007 25 infested trees were destroyed. In late summer 2007, another outbreak was detected in the western part of the industrial zone. Although it could not be determined whether these two outbreaks corresponded to new introductions or were related to previous infestations, observations suggested that in this industrial area, trees were already infested in 2005 and 2006 but that inspections had failed to detect the pest. In spring 2008 after the storm ‘Emma’, pruning operations were carried out in Braunau and 4 infested trees (Acer spp.) were found an area which had previously been infested (several trees had been destroyed there since 2001). Interestingly, in a branch of approximately 1 m long cut from an Acer tree, 7 living larvae were found, and all of them were able to complete their life cycle. In 2008, the monitoring programme was intensified in the eastern and western parts of the industrial zone, and tree climbers were appointed to inspect tree canopies in order to improve pest detection. As of April 2008, only 5 infested trees were found and no beetle was observed. Eradication efforts are continuing in Austria.
The situation of Anoplophora glabripennis in Austria can be described as follows: Present, only in the city of Braunau am Inn (Oberösterreich), under eradication.
