Actions Indicated

  • show / hide

Action

Statutory action against interceptions. Statutory action against outbreaks to be determined on a case by case basis according to circumstances.

General Comments

North American beetle with wood boring larvae, whose only recorded host is elm. Some uncertainty about the potential scale of impacts should the pest be introduced to the UK, but statutory action would be taken against interceptions, and would be considered on a case by case basis in the event of outbreaks
