Notes: Japanese wax scale (JWS), Ceroplastes japonicus Green (Hemiptera: Coccidae), is an important pest of about 90 host plants in the Southern Caucasus. It was first recorded in Sukumi (Georgia) in 1933. In 50-60 years this pest has spread throughout the Black Sea coast of Caucasus and has been recently acclimatized in all South Caucasus. Introduction of Scutellista caerulea (Fonscolombe) (= S. cyanea Motschulsky) (Hymenoptera: Pteromalidae) was made from Egypt, Italy and France in different years and a specific parasitoid of Japanese wax scale, Microterys clauseni Compere (Hymenoptera: Encyrtidae) was introduced from Japan in 1978-1984 to the Black Sea coast. The mortality of Japanese Wax Scale at low temperatures, density of JWS on the plants, influence of parasitoids on the control of pests and possibilities of entomophagous insects using in the biological control of this scale are discussed.
