Pest categorisation of .

The EFSA Panel on Plant Health performed a pest categorisation of (Voss, 1937) (Coleoptera: Curculionidae), following the commodity risk assessment of bonsai plants from China consisting of grafted on , in which was identified as a pest of possible concern to the European Union (EU). This categorisation refers to , which is the pest's current valid scientific name. It is native to China and has never been recorded in the EU. It completes from 2 to 3 generations per year. Eggs are laid in cracks and crevices of trunks and branches with bark thickness of approximately 0.6-1.2 cm. The pest overwinters as an adult or as a mature larva under the bark. Plants for planting, wood with bark and wood products provide pathways for entry. Although the weevil has been reported to carry the nematode it is not considered a vector. Climatic conditions and availability of host plants in some EU countries would allow to establish and spread. Impact on spp. is anticipated. Recognising that the weevil is reported to attack both weakened and healthy trees, there is uncertainty on the magnitude of impact. Its recorded capacity to attack non-Asian species also indicates its ability to adapt and expand the range of trees it can utilise as hosts, which could include European species. Phytosanitary measures are available to reduce the likelihood of entry and spread. meets the criteria that are within the remit of EFSA to assess for this species to be regarded as a potential Union quarantine pest.
