日本龟蜡蚧(Ceroplastes japonicus Green)、红蜡蚧(Ceroplastes rubens Maskell)和角蜡蚧[Ceroplastes ceriferus (Anderson)]。均为1年发生1代,以受精雌成虫在枝条上越冬,翌年3月上旬恢复活动取食、孕卵,5月下旬开始产卵,6月上、中旬若虫孵化,8月上、中旬两性产配,9月下旬雌成虫越冬;以若虫、成虫的针状口器吸食植物汁叶,导致树势衰弱,芽叶稀小,并诱发煤菌孳生,而影响景观与开花结果。它们均体被厚蜡层,防治时机不当,化学药剂防治很难奏效。必须掌握若虫盛孵期和若虫期(硬蜡阶段),采用内吸型或强剂型药剂,方可取到理想效果。
Ceroplastes japonicus Green, Ceroplastes rubens Maskell and Ceroplastes ceriferus (Anderson). 1 year occurred in 1 year to female adults fertilized wintering branches, early March the following year to resume activity feeding, pregnancy eggs, spawning in late May, June, the mid-nymphs hatch in August, the middle and last gender Production, in late September female adults overwintering; to nymphs, adult needle mouthparts to take plant juice leaves, resulting in weak bark, thin buds, and induce coal breeding, and affect the landscape and flowering results. They are thick body wax layer, prevention and control of improper timing, chemical control difficult to work. Must take control of nymphs during the incubation period and nymph period (hard wax stage), the use of inhaled or strong agent type, in order to obtain the desired effect.
