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

Actions Indicated

  • show / hide

Action

Statutory action against findings

General Comments

A disease complex involving an ambrosia beetle and fungus, native to Asia and Oceania but now invasive in other countries. The UK climate is likely to be a limiting factor regarding establishment. Watching brief needed for any pest spread into areas with cooler climates.

Further Information

Uncertainty
