DRAFT: Rapid Pest Risk Analysis (PRA) for: Pochazia shantungensis (and P. chinensis)
Description
Pochazia shantungensis is a hemipteran insect which is thought to be native to eastern China. It is now also found in South Korea, Japan and scattered locations in southern Europe. There are apparently established populations in parts of southern France, Pistoia in Italy, Sochi in Russia and around Istanbul in Türkiye. There have been detections of the pest in other parts of Europe, often linked with recently imported plants. In 2024 it was intercepted in England and Wales for the first time, with findings of the pest in multiple consignments of plants (hardy ornamental stock (HONS)) from Italy.
Pochazia shantungensis feeds on sap (phloem) of plants. Although the English name brown-winged cicada is commonly used, this insect is not a cicada and “brown-winged planthopper” would be more appropriate. The insects feed on a very wide range of plant species, both herbaceous and woody. Adults lay eggs deep inside young twigs of woody plants, and the pest overwinters as eggs in the twigs. There are one or two generations per year in the current range.
Pochazia chinensis is a very closely related species which was described in 2024 based on molecular differences. Before that analysis, it was regarded as conspecific with P. shantungensis. As nearly all published information may
refer to either species, this PRA does not attempt to distinguish between them and information presented for P. shantungensis may refer to either species (or both).
