The scale was univoltine. Overwintering stages were the third-instar nymph and the adult female. From the end of May until the end of June the population comprised preovipositing females. Oviposition occurred from mid-June until mid-July and hatching took place during July. First- and second-instar nymphs were recorded from the end of July until the end of August, and from mid-August until the end of September, respectively. Third-instar nymphs appeared at the end of August and were present until the beginning of September. Some of the population of third-instar nymphs reached the adult stage during October and November, whilst the remainder completed development in the following April. Small numbers of male nymphs were recorded during October and November. The mean fecundity of adult females was 3260 ± 770 eggs per female. The most abundant natural enemy of C. sinensis was Scutellista caerulea (Fonscolombe) (Hymenoptera: Pteromalidae), whose eggs, larvae and pupae were found in up to 42% of the total live population of the scale. Two predators, Chilocorus bipustulatus (L.) and Exochomus quadripustulatus (L.) (Coleoptera: Coccinellidae), were also observed.10aCeroplastes sinensis10aChilocorus bipustulatus10aExochomus quadripustulatus10afecundity10aHomoptera10aphenology10aScutellista caerulea1 aStathas, G.J.1 aKavallieratos, Nikolaos, G.1 aEliopoulos, P.A.  uhttps://icgf.myspecies.info/content/biological-and-ecological-aspects-chinese-wax-scale-ceroplastes-sinensis-del-guercio
