First report of Scaphoideus titanus in Germany
The NPPO of Germany recently informed the EPPO Secretariat of the first report of Scaphoideus titanus (Hemiptera: Cicadellidae - main vector of flavescence dorée) on its territory.
In August 2024, adult specimens of S. titanus were caught on yellow sticky traps belonging to the Staatliches Weinbauinstitut Freiburg (WBI, Baden-Württemberg) in two different vineyards (Vitis vinifera) located 4 km apart. The traps were put into place as part of the national survey programme. The identity of the pest was confirmed by the official laboratory, Landwirtschaftliches Technologiezentrum Augustenberg in Karlsruhe by morphological identification. As S. titanus is a vector of Grapevine flavescence dorée phytoplasma (EPPO A2 List), insect specimens were tested for the phytoplasma and found to be negative. Additional traps were installed at both locations to investigate the extent of the outbreak. In total, 225 adult specimens of S. titanus were caught on 21 yellow sticky traps. An intensified survey including traps and visual inspections will be carried out until the end of September 2024, as well as in the seasons 2025 and 2026.
The pest status of Scaphoideus titanus in Germany is officially declared: Present, in specific parts of the Member State, where host crop(s) are grown.
