The longhorned beetle species Trichoferus campestris (Faldermann 1835) [EPPO code: HESOCA] was intercepted in Sweden in July 2021. Larvae were found in a type of windscreen made of willow (Salix sp.) canes imported from China. 

The species is not listed as a quarantine pest in the EU ((EU) 2019/2072). However, based on Article 29 in the plant health law ((EU) 2016/2031) national measures against the pest has been taken in Germany (Swedish Board of Agriculture, pers. comm.). According to Article 29, an officially confirmed observation of a pest in a member state that may fulfil the criteria of a quarantine pest shall be assessed by the member state to conclude, based on criteria for a preliminary assessment, whether the pest provisionally qualify as union quarantine pest requiring temporary measures (Article 29 and Subsection 1, Section 3, Annex I in ((EU) 2016/2031). 

The pest is recommended for regulation as a quarantine pest by EPPO (added to the A2-list in 2007) (EPPO 2020a; 2021a). It is also subjected to statutory action against findings in the UK (Fera 2021) and it is regulated in Canada, Morocco, New Zealand, Turkey and USA (EPPO 2021a; IPPC 2020).

In order to determine potential risk management actions in response to the interception of T. campestris in Sweden further information about the potential impact of the pest is needed. SLU Risk Assessment of Plant Pests was therefore requested by the Swedish Board of Agriculture to provide a quick assessment of the potential economic, social and environmental impact of T. campestris in Sweden in relation to the criteria for a quarantine pest ((EU) 2016/2031).
