The demarcated area covers 42 km2 on the municipalities of Gien, Nevoy, Poilly-lez-Gien, Saint-Martin-sur-Ocre and Saint-Gondon. All infested trees were felled and destroyed. Preventive felling of host trees in an area of 100 m around the infested area was done. An awareness campaign is also being conducted.
The outbreak of A. glabripennis found in July 2004 in Sainte-Anne-sur-Brivet (Pays-de-la-Loire region) was officially declared eradicated in 2013, following eradication measures and 4 years of intensive monitoring without any discovery of insects or infested trees.
In Strasbourg (Grand Est region), the outbreak of A. glabripennis found in July 2008 was officially declared eradicated in April 2019 (EPPO RS 2019/097). Nearby, the German Weil-am-Rhein outbreak discovered in 2011 was officially declared eradicated in 2019 after 4 years without finding infested trees or insects, including within the French delimited zone situated in Huningue and Village-Neuf area.
