× Likelihood For "Pest is Introduced" the lowest value of Entry or Establishment, as both are required for a successful introduction. For "Pest Spreads to Maximum Extent" this is an expert judgement on the likelihood of this occurrence. See Guidance Document for more Information Close Likelihood [1 - 5]		2
× Spread The rate at which a pest can expand, by natural dispersal only, within an area. See Guidance Document for more Information Close Spread [1 - 5]			3
× Impact The highest value from economic, environmental or social impacts. See Guidance Document for more Information Close Impact [1 - 5]				4
× Value at Risk The value of the hosts or industries at risk from this pest in the UK. See Guidance Document for more Information Close Value at Risk [1 - 5]					5
× Likelihood x Impact The likelihood multiplied by the impact, which shows the risk to the sector. See Guidance Document for more Information Close Likelihood x Impact [1 - 25]	8

PRA Availability

EPPO (2003)

Provisional quarantine pest (Great Britain, as Xylotrechus spp.). EPPO A2

Action

Statutory action against findings

General Comments

Polyphagous longhorn beetle pest originating in Asia. Some uncertainty regarding risk to UK, but statutory action would be taken against findings on a precautionary basis.

Key uncertainty for pest

The suitability of the UK climate for build up of damaging populations of the beetle.
