Targeted monitoring at points of entry. Statutory action against findings. Research into role of fungal species and their effects on susceptibility of UK species of pine.

General Comments

Bark beetle native to the Americas but causing serious damage to pine trees following its introduction to China. Existing regulations provide protection against risk of introduction, although residual pine bark sometimes remains on packaging material and manufactured products. Research on fungal species will help better assess the susceptibility of UK pine species and to prepare a PRA. Targeted surveillance to be carried out at points of entry.
