Résumé

Routine survey work in the area where an adult Asian longhorn beetle was found in 2009 discovered signs of the beetle in Acer trees. Subsequent investigation revealed larvae in a tree - these were morphlogically identified and confirmed by DNA. Survey work is now underway to delineate the extent of the outbreak. Some 260 larvae have now been found as well as many adult emergence holes. Many trees have been felled in a buffer zone around the findings; this has been extended as a result of new findings. Felling in the area is now complete and there have been no further findings. Monitoring work will be needed for several years. There is circumstantial evidence which associates the outbreak with earlier imports of wood packaging supporting consignments of stone from the far-East.

Danger

Following felling of infested and potentially infested trees the danger level is much reduced
