Eradication of Anoplophora glabripennis from the Netherlands
As reported in EPPO RS 2010/200, an outbreak of Anoplophora glabripennis (Coleoptera: Cerambycidae – EPPO A1 List) was detected in November 2010 in the Netherlands. During pruning activities, the pest was detected in lane trees of Acer pseudoplatanus in an industrial area of the city of Almere. In total, 9 Acer pseudoplatanus and 1 Salix aurita were found to be infested within a range of 70 m. The plants were dissected and as a result, approximately 60 exit holes, 11 adults beetles (9 dead, 2 alive), and 7 living larvae were found (no eggs were observed). The date for formation of the exit holes ranged between 2007 and 2010. The majority of exit holes had been formed in 2008 and 2009 suggesting that the pest population was in a state of decline. This was the first outbreak of A. glabripennis in the Netherlands.
From November 2010 to February 2011, eradication measures were implemented. These measures included a clear-cut area, destructive sampling, specific surveillance and restrictions on the movements of host plant material. By the end of February 2011, all symptomatic trees and deciduous trees/shrubs located within a range of 100 m from infested trees were destroyed (in total 100 trees and 7 groups of shrubs). Specific surveillance was carried out within a radius of 1;000 m around the infected trees. In total more than 5;500 trees were inspected (tree climbers/trucks with aerial work platform) and no further specimens or signs of infestation were found. The NPPO of the Netherlands considered that A. glabripennis has been successfully eradicated. In the coming years, surveillance and restrictions on movement of host plant material will continue in the delimited area.
The pest status of Anoplophora glabripennis in the Netherlands is officially declared as: Absent – eradicated.
