× 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]	1
× 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]					5
× Impact The highest value from economic, environmental or social impacts. See Guidance Document for more Information Close Impact [1 - 5]		2
× 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]				4
× 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]	2

Regulated quarantine pest (Northern Ireland)

Action

No statutory action in Great Britain. Statutory action in Northern Ireland.

General Comments

Fruit fly found in northern Australia. Many fruit species have been recorded as hosts, mostly tropical fruit but some species grown in the UK. Damage has only been reported from areas with much warmer temperatures than the UK and overall the risk to UK fruit production is considered to be low.
