Notes: [Presented at the 4th Slovenian Conference on Plant Protection in Portoroz, March 3-4, 1999.] Ceroplastes japonicus was first observed in Slovenia in 1990 in Primorska on persimmon (Diospyros kaki) and provisionally identified as Ceroplastes rusci. It was observed later in Slovenian Istria and Goriska Brda. The pest has since been observed on a number of agricultural and ornamental trees, mostly on persimmon and laurel (Laurus nobilis). The origin of the pest, current distribution, biological cycle and morphological characteristics are discussed. The host plants were determined and the control measures were tested.
