scale insect

It was concluded that a higher VB2 content in the host plant in some degree was benefit to the scale insect occurring greatly in the polluted city environment.

由此认为，污染使树体内VB2含量增高很可能是促进该蚧虫种群增长的一个原因。

The insect mainly occurred at the foot of mountains, northern slopes and in thick bamboo forestlands, especially on the six years old bamboos, on which the scale insect was found on 93.3% of the trunks below 3 metres.

该虫主要发生于北坡、山脚、密林及6a生以上老竹，立竹3m以下虫口达933%。

From March to October, the two peaks of VB2 content were corresponded to the two feeding and quick development stages of the scale insect.

在一年中，VB2的含量呈现两个高峰期，正好与该蚧虫的两个取食期相吻合。
