The EFSA Panel on Plant Health performed a pest categorisation of Pochazia shantungensis (Hemiptera: Auchenorrhyncha: Ricaniidae) for the EU following commodity risk assessments of Malus domestica, Prunus persica, P. dulcis and Robinia pseudoacacia plants for planting from T € urkiye in which P. shantungensis was identified as a pest that could potentially enter the EU. The native range of P. shantungensis is China (Shaanxi, Shandong and Zhejiang provinces), but around 2010, the species entered the Republic of Korea and rapidly spread. Small and localised populations were also recently found in T € urkiye (Marmara) and southern Russia (Krasnodyarskiy kray). Within the EU, a few individuals have been recorded in Italy (Pistoia province, Tuscany), in one locality in southern France (Alpes-Maritimes), in the Netherlands (Western Netherlands) and in one garden in Germany (Baden-W € urttemberg) where it was eradicated. P. shantungensis is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. It is polyphagous, feeding on plants belonging to more than 200 species including many crop and ornamental plants. Economically important hosts in the EU include apple (M. domestica), citrus (Citrus spp.), walnut (Castanea sp.) and ornamentals such as hibiscus (Hibiscus spp.) and camellia (Camellia japonica), as well as forest trees, mostly deciduous. In the Republic of Korea, the species has one generation per year. It overwinters as eggs and goes through five nymphal instars. Its impact is due to oviposition obstructing the vascular system of its hosts, depletion of the host resources and egestion of honeydew promoting the development of sooty moulds. Plants for planting constitute the main pathway for entry into the EU and for spread. Climatic conditions in southern EU countries and host plant availability in those areas would allow establishment and spread. The introduction of P. shantungensis is expected to have an economic impact in the EU through the reduction in yield, quality and commercial value of fruits and ornamental plants. Phytosanitary measures are available to reduce the likelihood of entry and further spread. P. shantungensis meets the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.
