× 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]		2
× Impact The highest value from economic, environmental or social impacts. See Guidance Document for more Information Close Impact [1 - 5]			3
× 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]	6
× UK Relative Risk Rating Likelihood x Impact x Value at Risk. See Guidance Document for more Information Close UK Relative Risk Rating [1 - 125]	30

General Comments

Longhorn beetle that is present in China and South-East Asia, recently expanding its range to South Korea. Although information on impacts is limited, damage from larval feeding might be expected on oak and elm in the wider environment as well as Camellia. Other beetles within this genus are known to be highly damaging.
