In 2011 the European and Mediterranean Plant Protection Organization (EPPO) decided to recommend its member countries to regulate Agrilus anxius as a quarantine pest. On this background Mattilsynet has asked for a risk assessment as a basis to decide whether the bronze birch borer should be regulated as a quarantine pest in Norway, and if so, which phytosanitary measures should be implemented to prevent entry and establishment in the country. A pest risk analysis (PRA) by EPPO in 2011 should be used as a basis for the assessment.
