Exotic beetle pest outbreak threatening UK broadleaved trees

Asian longhorn beetle found in Kent
March 2012. An outbreak of the Asian longhorn beetle (ALB), an exotic beetle pest which could have severe consequences for British trees, has been found in Kent the Food and Environment Research Agency (FERA) have confirmed. This is the first time an outbreak of this pest has been found in the UK and it is being treated extremely seriously. Fera and the Forestry Commission are taking urgent steps to try to eradicate the outbreak before it has the chance to spread further afield.

Several larvae of the beetle have been found inside a poplar tree during a routine survey by the Forestry Commission at a site in the Paddock Wood area. Scientists from Forest Research had been monitoring an area around the site where an adult beetle had been found in 2009 and this is the first evidence of infestation. It is thought the beetles originated from wood packaging used to import stone from China at an adjacent industrial site.
Non native beetle
The beetle is not native to the UK, and poses a serious threat to a very wide range of broadleaved trees and shrubs such as maple (including sycamore), elm, horse chestnut, willow, poplar, birch and some fruit trees.
Speaking about action to eradicate the outbreak Martin Ward, Head of Plant Health Policy at Fera said, "Our Plant Health Inspectors and the Forestry Commission are conducting a survey to determine the extent of this outbreak. They will be contacting all those within the survey area over the next few days and weeks with a view to inspecting all potential host trees for signs of the beetle. In the meantime we would urge members of the public, local businesses and landowners to be on the alert for the beetle and let us know if they find anything.
Asian longhorn beetle description
Adult beetles are large (around 20 - 40 mm long), shiny black with variable white markings. Their antennae are particularly distinctive being much longer than their bodies (up to twice the body length) and are black with white/light blue bands. The larvae of the beetle feed undetected on the inside of the plant and can kill it or leave it weakened and susceptible to further pest and disease damage.
