Abstract The EFSA Panel on Plant Health performed a group pest categorisation for the EU territory of non‐EU Scolytinae (Coleoptera: Curculionidae) non‐coniferous hosts, which total 6495 known species.

Abstract The European Food Safety Authority (EFSA) was mandated by the Union (EU) to perform a group pest categorization of exotic Scolytinae (Coleoptera: Curculionidae) whose establishment in EU territory would present significant risk terms plant health. This should be used reconsider listing ‘Non‐European Scolytinae’ as quarantine pests current Regulation. In first stage, EFSA short‐listed 88 species developing on broadleaf hosts and known for their mobility, having impact levels documented literature either absent or with limited presence EU. then asked Reference Laboratory (EURL) provide comments related its expertise diagnosis insects, assess practical technical implications including these list submitted future regulation? EURL proceeded case‐by‐case examination ranked overall feasibility identification, from A (both morphological molecular tools available) D (none available). Several issues were also raised. particular, identification using sequences hosted NCBI GenBank Bold databases proved highly hazardous. case Euwallacea fornicatus complex especially problematic because multiple taxonomy available distinction constitutive species. As result, we proposed recommendations consideration modifying EFSA's selected developed next working programme.
