This pest has been assessed for the Risk Register and is considered to pose a low risk to the UK. The information on this pest was correct as of 10/10/2017, but is no longer actively maintained. It will only be updated if new information is received which indicates the potential for a significant increase in risk to the UK.
For pests currently absent from the UK, risk of introduction is assessed. For pests already present in the UK risk of spread to maximum extent is assessed. Some other scenarios exist.
The specific pathway(s) that were considered when rating entry of a pest to the UK. These were the pathways considered to present the highest risk of entry.
All pathways the pest may enter or spread around the UK on.
What risks would be without any co-ordinated action. Ratings do take into account how normal grower practises (such as pesticide treatments) would affect risks.
See Guidance Document for more Information
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.
The Likelihood of movement of the pest into the UK on a pathway and transfer of that pest to a suitable host.
The likelihood of the pest surviving and perpetuating in the UK for the foreseeable future after it has entered.
The rate at which a pest can expand, by natural dispersal only, within an area.
The highest value from economic, environmental or social impacts.
The predicted economic impacts of the pest in the UK. This includes direct effects on yield, quality and possible indirect effects such as trade implications.
The proportion of the environmental value of the plant which is likely to be lost through the introduction of the pest.
The predicted social impacts of a pest in the UK, including effects on tourism, amenities and animal and human health.
The value of the hosts or industries at risk from this pest in the UK.
The likelihood multiplied by the impact, which shows the risk to the sector.
Likelihood x Impact x Value at Risk.
All mitigations currently in place for a pest.
Risks rated to take into account the effects of co-ordinated actions that are in place such as EU regulation or industry accreditation schemes.
The hosts or industries in the UK that were considered when rating the pest as being at risk.
Indoor fruit production

A summary of priorities for action.
No statutory action against findings
Vinegar fly present in the Mediterranean region and outside Europe. Mainly a secondary pest and unlikely to cause impacts greater than native fruit flies.
Ticks indicate key sources of uncertainty for this pest. A cross indicates that there is less uncertainty associated with that aspect of the pest’s biology. A cross does not indicate there is full knowledge, merely that the uncertainties are unlikely to influence the rating (score).
