Deciduous trees infested by Asian long-horned beetle to be felled in Itä-Hakkila, Vantaa

29.10.2015

<p>Finnish Food Safety Authority Evira has ascertained that Asian long-horned beetles <em>(Anoplophora glabripennis)</em> have infested trees growing in Itä-Hakkila, Vantaa, some years ago. Almost all broad-leaved trees within the contaminated area will have to be felled in order to destroy the beetle. Evira says that, for the time being, people in the Itä-Hakkila area should not start felling deciduous trees on their own, but residents and businesses should await instructions from Evira.&nbsp;</p>

In the next few days, Evira will define the infested area where the trees must be felled and transported for chipping and burning during the winter. The residents and businesses in the area will also be directly informed of the boundaries of the infested area.

The large Asian long-horned beetle larvae live inside the tree and make large tunnels in the trunk. As a consequence, branches wilt and finally the whole tree will die. The beetles attack live, healthy deciduous trees, so they are no danger to buildings. Almost all domestic deciduous tree species, such as aspen, poplar, willow, maple, birch, rowan, linden, elm, alder, apple and pear trees, act as host trees of the Asian long-horned beetle.

Inspections in buffer zones to be continued

Large insects were spotted in the industrial area, so Evira’s inspectors checked all the trees within a radius of one hundred metres of the discovery site. The inspection found live Asian long-horned beetle larvae and an adult wood boring beetle.

Once all the trees with the symptoms have been found, the infested area can be defined. A buffer zone two kilometres wide will be created around the infested area, within which the inspections will continue. The measures comply with the European Commission decision.

Further information on Evira website

Evira will provide additional information on the matter on its website as more becomes known. In particular, Evira asks the residents of Itä-Hakkila, Vantaa, to follow the web page  www.evira.fi/aasianrunkojaara (in Finnish). The pages also have images of the Asian long-horned beetle and a map of the area where the wood boring beetles have been found to date. A residents’ evening is also planned.

Instructions on reporting a sighting

If you spot adult Asian long-horned beetles please inform Evira. Instructions on identification and further information at:  www.evira.fi/aasianrunkojaara (in Finnish).

The Asian long-horned beetle (Anoplophora glabripennis) is an insect species originating from China, and it has spread in wooden packaging materials to North America and Europe. In Finland, and also elsewhere in the EU area, it has often been found in consignments of stone from China. In recent years, Evira has issued warnings about the plant pest risks associated with this stone.
