Update on the situation of Leptinotarsa decemlineata in Finland
The NPPO of Finland recently informed the EPPO Secretariat that Leptinotarsa decemlineata (Coleoptera: Chrysomelidae – EPPO A2 List) has been found on its territory. It can be recalled that L. decemlineata has occasionally been found in Finland, but that outbreaks have always been subject to eradication measures and not followed by establishment.
In July and August 2024, outbreaks were detected in Southern Finland: on 2 sites in the municipality of Hamina (Kymenlaakso region) and 2 sites in the municipality of Lappeenranta (South Karelia region). In all four cases, official measures have been taken to eradicate the pest.
The pest status of Leptinotarsa decemlineata in Finland is officially declared as: Present, under eradication.
