Hellenic Plant Protection Journal 6: 55-57, 2013 SHORT COMMUNICATION First record of the scale insect Asterodiaspis ilicicola in Greece and additional data about the scale Gonaspidiotus minimus on Quercus ilex G.J. Stathas, E.D. Kartsonas and P.J. Skouras Summary The scale insect Asterodiaspis ilicicola (Targioni Tozzetti) (Hemiptera, Coccoidea, Asterole- caniidae) was recorded for the fi rst time in Greece in February 2013. It was found on Quercus ilex, in the National Garden of Athens. On the same infested trees, the scale insect Gonaspidiotus minimus (Leonar- di) (Hemiptera, Coccoidea, Diaspididae) was also recorded. Both scale species were settled on the up- per surface of leaves of Q. ilex. According to ScaleNet Database (Ben-Dov et al., 2013) the scale insects species of the family Asterolecaniidae recorded in Greece include Asterodiaspis bella (Russell) (Russell, 1941; Borchsenius, 1960), A. repugnans (Rus- sell) (Russell, 1941; Borchsenius, 1960), A. va- riolosa (Ratzeburg) (Milonas et al., 2008) and Pollinia pollini (Costa) (Alexandrakis, 1980). Asterodiaspis ilicicola (Targioni Tozzetti) (Hemiptera, Coccoidea, Asterolecaniidae) was recorded for the fi rst time in Greece on Figure 1.

On the same trees, the scale insect Gonaspidiotus mini- mus (Leonardi) (Hemiptera, Coccoidea, Dias- pididae) was also recorded. The colonies of both scale species were settled on the up- per surface of leaves of Q. ilex (Fig. 1 and Fig. 2). The vouchers of the permanent slides of A. ilicicola are deposited in collections of the University of Padova and of the Laboratory of Agricultural Entomology & Zoology of the Highest Technological Educational Institute of Kalamata.

Το έντομο βρέ- θηκε επί του Quercus ilex, στον Εθνικό Κήπο της Αθήνας. Στα ίδια προσβεβλημένα δένδρα βρέθηκε και το κοκκοειδές έντομο Gonaspidiotus minimus (Leonardi) (Hemiptera, Coccoidea, Diaspididae). Και τα δύο αυτά είδη βρέθηκαν εγκατεστημένα στην άνω φυλλική επιφάνεια του Q. ilex. Hellenic Plant Protection Journal 6: 55-57, 2013 © Benaki Phytopathological Institute.
