作者于1994～1997年在广西全州县国营咸水林场的哈姆林甜橙园对柑桔褐圆蚧进行了连续观测和防治试验。结果如下。 1 发生规律 褐圆蚧活动型虫态出现在5月下旬至10月下旬,有4次若虫孵化高峰期。各次若虫初见期与始盛期相距6～10天,初见期到上果(叶)固定取食为10～12天。褐圆蚧以受精雌成虫和二龄若蚧在被害枝、叶上越冬。雌成蚧产卵前固定不动,卵产于母体下。产卵结束,待大部或全部幼蚧孵化后,成虫身体便干缩死亡。产卵量与虫体大小及寄生部位不同有明显关系,虫体较大或寄生于果上的雌成
The author conducted continuous observation and control experiments on Citrus grandiflorum from 1994 to 1997 in Hamlin Orange Garden in Guangxi State-owned Salt Water Forest Farm. The result is as follows. Occurred regular brown scale insect activity occurred in late May to late October, there are 4 nymphs peak incubation period. Each nymph initial period and the beginning of the period of 6 to 10 days, the initial period to fruit (leaf) fixed feeding for 10 to 12 days. Brown scale insects to fertilized female adults and second instar scales in the victim branches, the leaves wintering. Female adult scale pre-fixed eggs, eggs produced in the mother. Spawning ends, until most or all of the baby scales hatch, the adult body will shrink dry death. The number of spawning and parasitic body size and the different parts of a clear relationship between parasites in the parasites on the female or larger
