Pest risk analyses

Pest risk analysis (PRA) is the process of evaluating biological or other scientific and economic evidence to determine whether an organism is a pest or pathogen, if it should be regulated and to identify control measures to be taken against it.

We welcome views and comments on the PRAs. In submitting any comments you may wish to focus on the summary, key uncertainties and conclusion sections of the risk assessment and to consider the following:

  • Are any factual corrections required?
  • Your view on the appropriateness of the current recommendation(s)?
  • Can you provide any additional information (or links to other sources of information) that may help address uncertainty identified in the assessment/management measures?
  • Are there any risks that have not been adequately considered?

Any comments should be sent by the date specified, in writing or by email to:

The Risk and Horizon Scanning team, the Department for Environment, Food and Rural Affairs Room 11G31 Sand Hutton York YO41 1LZ.

Email: plantpestsrisks@defra.gsi.gov.uk

Comments received will not be attributed to individuals without permission in any published summary, but may have to be released if a request is received under the Environmental Information Regulations.

Only PRAs currently published for review are displayed on this page. A list of all pests for which a PRA is available can be accessed via the plant health portal search facility along with the current list of pests for which development of a PRA is considered a priority following addition to the risk register.  PRAs for specific pests are also accessible via their individual entry on the plant health risk register.

Euzophera bigella

Euzophera bigella

Crop/sector considered most at risk in the UK

Larvae have been recorded feeding both within fruit and under the bark in wood in a number of fruit trees. Nearly all host records refer to crop species. It seems likely that other wild or cultivated fruit hosts, particularly stone fruit, may be susceptible for development of this species.

Recommendation

It is the recommendation of the Plant Health Risk Group (PHRG) that statutory action be taken on interceptions of this organism but that action in the wider environment would prove challenging, and that introducing measures on fruit and growing trees from Europe would prove difficult to justify against the proportionate risk to the UK.
