Update on the outbreak of Anoplophora glabripennis in Alsace (FR)
The NPPO of France recently sent the EPPO Secretariat more information about the outbreak of Anoplophora glabripennis (Coleoptera: Cerambycidae – EPPO A1 List) in Alsace. Two poplar trees infested by A. glabripennis had been discovered in July 2008 at the port of Strasbourg (EPPO RS 2009/045), and it was suspected that the pest had been introduced via imports of granite from China. The two infested trees were destroyed and surveys carried out in 2008 and 2009 within a radius of 1000 m (including the city of Strasbourg) did not detect the pest. However in July 2010, exit holes were detected on 3 Acer trees located 250 m away from the initial finding. Investigations showed that these infested trees contained larvae at different development stages and 2 adult beetles. Infested Acer trees were destroyed and intensive surveys are being carried out within a 1000 m radius. All potential host trees located in the vicinity of this outbreak will be removed next winter (2010/2011), and intensive surveys will continue in 2010/2011.
