黄圆蹄盾蚧生物学特性及其种群动态研究

Studies on Biological Characteristic and Population Dynamics of Aonidiella citrina

黄圆蹄盾蚧是园林绿化植物的主要害虫之一,通过田间系统调查表明:黄圆蹄盾蚧对城市园林绿化植物危害较为严重,且对不同的寄主植物的危害特点和危害程度不同。黄圆蹄盾蚧在昆明地区1年发生3代,世代重叠现象明显,以雌成虫越冬,1年中以夏秋季虫口数量最多,危害较严重;在方位上,黄圆蹄盾蚧在云南樟树冠北面枝叶的虫口数量最多,东、西面次之,南面的最少。

Aonidiella citrine is one of the main pest insects of ornamental plants. The results of investi gation in the fields showed that the growth of the ornamental plants in greenbelt was seriously damaged, and the damaged characteristic and degree of different host plants were different. There were three generations in one year in Kunming, and had distinct generation overlapping. They overwintered in female imagoes. The largest number of the population came between summer and autumn and the damage was very serious. According to its orientation of the Cinnamomum glanduliferum, the number of the population was largest on the north, smallest on the south and medium on the east and west.
