In the frame of a national survey program, a monitoring for the presence of Scaphoideus titanus was conducted in the southern part of Baden-Württemberg, Germany. Yellow sticky traps were installed in different vineyards in a zone of about 20 km north to south close to the Rhine Valley from July until October 2024 with a two-week change. At the beginning of August, the first specimens were detected and identified as S. titanusand until the end of September, about 500 further S. titanus were collected on the traps. In total, 436 individuals were analysed for phytoplasma infection with different molecular methods. So far, no “flavescence dorée” phytoplasma presence could be confirmed. However, some suspicious cases made a reliable diagnostic difficult. Therefore, a quantitative PCR assay was developed to check the quality of S. titanus DNA extraction.
