Anoplophora chinensis found on Cornus and Crataegus in the Netherlands
In December 2007, isolated findings of Anoplophora chinensis (Coleoptera: Cerambycidae – EPPO A2 List) had been made in the Netherlands (EPPO RS 2008/002) and were subjected to eradication measures. In mid-August 2009, 3 infested plants were detected in the municipality of Westland very close to the former located Acer and Corylus trees (within a radius of 5 m) that had been found infested by A. chinensis at the end of 2007 and subsequently removed. Two larvae were found in 2 Cornus plants (1 larva per plant) and 2 fresh exit holes were observed in a neighbouring plant of Crataegus sp. The infested plants were growing along a road together with other shrub species (Rosa, Philadelphus). This small row of plants was located near a company which had imported Acer plants from China during the period 2002-2007. So far, Cornus species were not known to be host plants of A. chinensis.
The infested area has been delimited but it remained the same as in 2007/2008 (as all new findings were made within the infested zone) and phytosanitary measures were taken according to Commission Decision 2008/840/EC of 7 November 2008. Pictures of the demarcated area and eradication campaign can be viewed on the PD website. By the end of 2009, all outdoor deciduous trees and shrubs growing within the infested zone and within a radius of 100 m around it will be removed, inspected and destroyed. One crop of Hydrangea spp. for cut flower production located near the infested zone will be pruned and inspected under official supervision of the NPPO. Surveillance of the demarcated area will continue until 2013. At a national level, surveillance activities will also include Cornus and Crataegus species in addition to the host species listed in the Commission Decision 2008/840/EC.
The pest status of Anoplophora chinensis in the Netherlands is officially declared as: Transient, isolated outbreak, only detected on Acer sp., Cornus sp., Corylus sp., and Crataegus sp., under eradication.
