The nymph and imago feed by sucking host’s juices, which affected the host’s growth and ornamental value. Ceroplastes pseudoceriferus damages more the Machilns yunnanensis, filamental flowering crab, Michelia sphaerantha, Michelia yunnanensis and cedar more severely, among them, the damage rate of Michelia sphaerantha can reach over 90 percent. Ceroplastes centroroseus does major harm to Hedera helix, Cinnamomum camphora, Yulania denudate and so on, among these plants it is the most harmful to Hedera helix. The genus insects gives rise to new generations once a year in Kunming. Through the survey on the life story of Ceroplastes pseudoceriferus Green and Ceroplastes centroroseus Chen, the author of this paper found out that the oviposition of Ceroplastes pseudoceriferus Green occurs in early of middle of August, and the eclosion of it occurs in late August. The hatching peak is in early September while overwintering with the instar nymphs. And Ceroplastes pseudoceriferus which lives in different host show different life story. So, while controlling the Ceroplastes pseudoceriferus in specific plant, people should control it according to it’s life story on the host plant. Ceroplastes centroroseus spawn in early July and begun to hatch, pleted basic eclosion in mid to late July and pleted basic fixation in early August. An ideal and effective way to control Ceroplastes Gray is natural enemy insect, so people should give priority to it while controlling Ceroplastes Gray .When people control Ceroplastes Gray chemically, they should control 1~2 nymph in Supracide 20 EC and Spirotetramat SC, for they have excellent control result in controlling 1`2nymph, with over 90 percent controlled. Besides, when people are planting Ceroplastes Gray host plants, they had better plant them in apricus and low humidity environment to prevent the damage of Ceroplastes Gray.
