General Comments

Scale insect affecting Prunus in central European countries and spreading northwards in Europe. Limited evidence of impacts to commercial or ornamental Prunus. Evidence suggests that trees in urban environments, where hosts are exposed to other environmental stresses, are more likely to be a target of the pest than orchard and ornamental trees in northern Europe.

Further Information
