Situation of Rhagoletis cingulata in Germany
In Germany, the first specimen of Rhagoletis cingulata (Diptera: Tephritidae - EPPO A2 List) was caught in 1999 in Rheinland-Pfalz (EPPO RS 2002/006). In 2003, a few specimens were caught on yellow sticky traps in cherry orchards in the same area. Since 2004, the number of insects caught in the cherry-growing areas of Rheinland-Pfalz increased considerably and the species started to be found in other parts of the country (EPPO RS 2006/003). In recent studies, it is stated that R. cingulata has been detected in the main cherry-growing regions of Germany: Baden-Württemberg, Brandenburg, Bayern, Hessen, Hamburg, Niedersachsen, Nordrhein-Westfalen, Rheinland-Pfalz, Sachsen, Sachsen-Anhalt and Thüringen, attaining high abundance in some of these regions. It is also noted that R. cingulata mainly occurs in sour cherry (Prunus cerasus) orchards, and in areas where Prunus mahaleb and Prunus serotina are present. In some years and locations, it is estimated that R. cingulata has caused more than 20% damage in sour cherries.
The situation of Rhagoletis cingulata in Germany can be described as follows: Present, first caught in 1999 in Rheinland-Pfalz; now found in Baden-Württemberg, Brandenburg, Bayern, Hessen, Hamburg, Niedersachsen, Nordrhein-Westfalen, Rheinland-Pfalz, Sachsen, Sachsen-Anhalt, Thüringen, mainly on Prunus cerasus (sour cherry).
