This pest survey card was prepared in the context of the EFSA mandate on plant pest surveillance (M‐2017‐0137) at the request of the European Commission. Its purpose is to guide the Member States in preparing data and information for the surveys of the nine Pissodes species regulated in the EU. These are required to design statistically sound and risk‐based pest surveys, in line with current international standards.The nine Pissodes species regulated in the EU as Union quarantine pests are Pissodescibriani, P. fasciatus, P.nemorensis, P. nitidus, P. punctatus, P. strobi, P. terminalis, P. yunnanensis andP. zitacuarense. All of them are absent from the European Union and attack conifer trees. The high availability of hosts, climatic suitability and ecological plasticity of these weevils make the entire EU territory suitable for their establishment. Detection surveys should mainly focus on the genera Cedrus,Picea,Pinus andPseudotsugawhile in the case of an outbreak, delimiting surveys should includeall coniferous species that can be found in the survey area. The main risk activities relevant for surveillance are the movement of propagation material of Cedrus, Picea, Pinus andPseudotsugaand the import into the EU of host plant material used for decorative purposes (e.g. Christmas trees). Visual examination is more effective for those Pissodes species that attack the healthy leaders of young trees than for species that boreinto the lower portions of the stem and root collar of stressed plants. The efficacy of traps has not been confirmed for all species and when specimens, both larvae and adults, are collected they should undergo molecular identification, whenever possible.
