C.;sativa is mainly grown in Southern Germany, such as Baden-Württemberg (around 3000 ha) and in Rheinland-Pfalz (around 2000 ha). Nurseries were also included in the monitoring survey. This survey was carried out by the plant protection services in cooperation with the forest management in the framework of the regular inspections for relevant forest pests. Characteristic symptoms of D. kuriphilus, i.e. galls, were not observed. Therefore, there was no need to take samples for further laboratory testing.
