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 Likelihood [1 - 5]			4
Entry The Likelihood of movement of the pest into the UK on a pathway and transfer of that pest to a suitable host. See Guidance Document for more Information Entry [1 - 5]			4
Establishment The likelihood of the pest surviving and perpetuating in the UK for the foreseeable future after it has entered. See Guidance Document for more Information Establishment [1 - 5]				5
Spread The rate at which a pest can expand, by natural dispersal only, within an area. See Guidance Document for more Information Spread [1 - 5]		2
Impact The highest value from economic, environmental or social impacts. See Guidance Document for more Information Impact [1 - 5]		2
Impact - Economic 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. See Guidance Document for more Information Impact - Economic [1 - 5]		2
Impact - Environmental The proportion of the environmental value of the plant which is likely to be lost through the introduction of the pest. See Guidance Document for more Information Impact - Environmental [1 - 5]	1
Impact - Social The predicted social impacts of a pest in the UK, including effects on tourism, amenities and animal and human health. See Guidance Document for more Information Impact - Social [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 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 Likelihood x Impact [1 - 25]	8
UK Relative Risk Rating Likelihood x Impact x Value at Risk. See Guidance Document for more Information UK Relative Risk Rating [1 - 125]	40

Actions Indicated

Action

No statutory action Justification: Limited information regarding impacts in protected cultivation in Europe, and no indication that this thrips species causes higher levels of impacts than Frankliniella occidentalis (western flower thrips), a pest which is already established in UK glasshouses. This pest has been on the radar of EPPO since 2000 but was removed from the Alert List in 2001. Since then, no other country has regulated this pest, and as the pest is present in several EU countries which we import many hosts from, it is unlikely that we could prevent this pest from entering the UK.

General Comments

Polyphagous thrips species native to Asia. This pest is now also present in parts of Africa and the Americas and has been found in several countries in Europe. There is no indication that this thrips species causes higher levels of impacts than thrips species which are already established in UK glasshouses.
