Provisional quarantine pest (Great Britain), quarantine pest (Northern Ireland) (both as Euwallacea fornicatus sensu lato). Quarantine pest (as non-European Scolytidae spp.).

Actions Indicated

  • show / hide

Action

Statutory action against findings

General Comments

An ambrosia beetle, native to Asia, now invasive in many parts of the world, including a glasshouse outbreak in Europe. The beetle requires symbiotic fungi to survive, such as Fusarium ambrosium or related species. It appears likely that many broadleaved trees grown in the UK are suitable hosts. Climate is likely to limit outdoor establishment in the UK, but heated botanical glasshouses are more at risk.

Further Information

Uncertainty

  • show / hide

Key uncertainty for pest

Repeated taxonomic revisions for the species group mean that older data often cannot be unambiguously assigned to a species.
