Yang, C.C., Du, C.J., Li, X.L., & Zhang, X.S. 1996 [Studies on the estimation of egg number and ovipositing phase of Ceroplastes japonicus Green.]. 16: 1, 53-56.

Notes: The relationship between weight and size of adult females of Ceroplastes japonicus and the numbers of eggs laid was analysed. Egg number was closely related to adult weight. The initial temperature for egg development and effective accumulated temperature were 15.5°C and 199.2 day-degrees C, resp., on tea, and 15.0°C and 216.44 day-degrees on jasmine.
