Details on the situation of Phyllonorycter issikii in Germany
As reported in the EPPO RS 2003/135, Phyllonorycter issikii (Lepidoptera: Gracillariidae – EPPO Alert List) was found for the first time in Germany (Sachsen) in 2002 on Tilia cordata. Following this notification, regional plant protection services were requested by the NPPO to pay attention to possible occurrences of this pest. As a result, P. issikii was also observed in Brandenburg, especially in the south-east part of the region around Cottbus. Isolated findings were observed in the eastern part around Frankfurt/Oder and Eberswalde. P. issikii has not been observed in other regions. The areas in Sachsen and Brandenburg where P. issikii has so far been observed adjoin Czech Republic, where the pest is already known to occur. It is therefore assumed that P. issikii has been introduced by natural spread.
The declared status of P. issikii in Germany is: Present, only in some areas.
