Both the PRA record and the PRA report are available. 

These PRA documents  from 2007 were modified in 2021 and 2023 to clarify and adjust the phytosanitary measures recommended

Probability of entry is low

 • Plants for planting of host plants of more than 15 cm diameter: low

 • Round Wood of host plants of M. mutatus: medium 

• Sawn wood of host plants of M. mutatus: very low 

• Wood packaging material: very low 

The probability of entry is considered to be low mainly because few commodities are imported from the areas where the pest is present. The pest is only likely to survive in living trees or round wood. Nevertheless it should be noted that it is suspected that one single trial consignment of round wood of Populus with bark may have resulted in the introduction of the pest to the Campania region in Italy. 

Probability of establishment is high in Albania, Algeria, Croatia, France, Greece (including Crete), Egypt, Israel, Italy, Lebanon, Montenegro, Morocco, Palestine, Portugal, Romania, Serbia, Spain, Syria, Tunisia, Turkey.

The economic impact is high. Main impact is on wood quality but reductions in production have also been noted for fruit trees.
