The European fruit lecanium (EFL), Parthenolecanium corni Bouché (Hemiptera: Coccoidea), is a common and harmful soft scale, which attacks Fraxinus oxycarpa Willd. and other ornamental and orchard plants in Tbilisi, Georgia. This study investigates the phenology, degree of plant damage and effect of parasitoids on this scale in Tbilisi, a densely populated area. We present data on the 32 species of chalcidoid parasitoids recorded from EFL in Georgia and south-eastern Europe. The scale is heavily parasitized in Tbilisi, but we did not find any variation in seasonal abundance. The most common parasitoid of EFL was Blastothrix longipennis (Hymenoptera: Encyrtidae).
