Abstract
This study provides the first documented discovery of symptoms caused by the cicada Stictocephala bisonia (buffalo treehopper) in Luxembourgish viticulture. Symptoms were found in 2022 in red grapevine cultivars, also in 2023 symptoms on vine plants occurred and two adults of the buffalo treehopper were caught. A characterisation of the resulting symptoms and a discussion on the species’ potential pest status depending on annual meteorological conditions are provided.
