Cydalima perspectalis (Walker, 1859) (Lepidoptera, Crambidae) and the threats for the Nature 2000 Habitat 5110 in Liguria (NW-Italy)

The authors report on the widespread occurrence of Cydalima perspectalis in spontaneous stands of Box (Buxus sempervirens) in Liguria corresponding to "Habitat 5110 - Stable xerothermophilous formations with Buxus sempervirens on rock slopes (Berberidion p.)” according to EU Habitats Directive. After a preliminary assessment, six Special Area of Conservation (SACs) are affected, where severe damage extends to some 370 hectares, corresponding to approximately 70% of the area. Finally, the authors suggest some guidelines for future surveys and control measures to limit the damage.
