Both the PRA report and the full PRA record are available. 

Fruit tree species such as Malus, Pyrus and Prunus are widely grown across the EPPO region. Cotoneaster, Crataegus, and Sorbus are widely planted in parks and gardens for ornamental purposes and also occur in the wild as well as wild Malus, Pyrus and Prunus. S. candida is an incidental pest in nurseries and young plantations. Because of the hidden behaviour of S. candida, the pest is likely to be moved undetected inside infested host plants. Control is difficult as the insect spends most of its life cycle inside the trees. The economic impact if introduced in the EPPO region is evaluated as medium by the EWG

2021: The PRA report was modified to clarify the phytosanitary measures recommended
