Rhagoletis suavis found in Berlin (DE)
In 2013, Rhagoletis suavis (Diptera: Tephritidae – EU Annexes) was found for the first time in Germany (see EPPO RS 2014/011). This North American fruit fly was discovered on walnut (Juglans sp.) in a private garden in Kleinmachnow (Brandenburg). In August 2016, R. suavis was also found in Berlin (borough of Steglitz-Zehlendorf). A single adult specimen was observed on a house wall close to Juglans regia trees. This occurrence was notified by a private individual to the NPPO. The pest was identified morphologically by the JKI laboratory in Kleinmachnow. It is supposed that R. suavis has spread naturally from Brandenburg to Berlin. The individual was advised to destroy infested nuts and husks in his/her land. No other official phytosanitary measures were taken because the pest has been present in Brandenburg (adjacent to Berlin) for a few years, and no effective phytosanitary measures are currently available.
The pest status of Rhagoletis suavis in Germany is officially declared as: Present, only in certain areas (Brandenburg, Berlin).
