This projects aims to provide a better understanding of the risks posed by Asian longhorn beetle in the UK. The detailed information obtained by the project will also help to improve future surveys and monitoring.
The objectives of the current analysis are to:
The most important host species at Paddock Wood was sycamore, Acer pseudoplatanus. Twenty-six per cent of all A. pseudoplatanus growing within the outbreak area were attacked by ALB and this species contained 70 and 98 per cent of the total larvae and adult exit holes, respectively. In comparison, only 3 per cent of field maple (Acer campestre), poplars (Populus spp.), willow (Salix spp.) and birch ( Betula pendula) were attacked. ALB larvae and pupae were found in branches with a diameter as small as 2.1 cm, but most occurred in stems and branches 4–10 cm in diameter.
Research on the ALB outbreak started in March 2012 and the analysis of the life-cycle and outbreak history are on-going.
To report a finding of Asian Longhorn Beetle to Forest Research scientists use TreeAlert.
If possible, the beetle should be caught and placed in a secure container such as a glass jar so that a Plant Health inspector can collect it.

Asian Longhorn Beetle Pest Alert
Asian longhorn beetle (ALB) is native to China and the Korean peninsula, and poses a serious threat to a wide range of broadleaved trees. The main pathway for entry into the UK is wood packaging material that has not been treated and individual specimens of Asian longhorn beetle have been found in the UK on a number of occasions.
In March 2012 a breeding population of ALB was confirmed by Forest Research scientists in the Paddock Wood area near Maidstone in Kent. A joint operation by the Forestry Commission, Forest Research, the Food and Environment Research Agency (Fera) and Defra appears to have been successful in eradicating the outbreak.
