柳蛎蚧在树干上的分布（累计虫口密度）规律为树干中部＞上部＞下部．树干上北方位虫口数较南方位虫口多．严冬、酷夏后死亡率高。通过对黑龙江省１０个市县柳蛎蚧发生面积与温度、湿度等气象因子关系的研究．建立了柳蛎蚧发生面积的多元线性回归预测模型、经检验证明．用该模型进行初步预测是可靠的。柳蛎蚧有螨类、瓢虫、寄生蜂及寄生蝇等多种天敌。
The distribution of the oyster scale on the trunk (cumulative population density) was in the middle part of trunk> upper part> lower part. The number of insects on the trunk in the north is more than those in the south. Harsh winter, cool summer high mortality. Through the study on the relationship between the occurrence area and the temperature and humidity of the Oyster Oyster scale in 10 cities and counties in Heilongjiang Province. A multiple linear regression model was established for the occurrence area of the oyster scale, which was verified by the test. The initial prediction with this model is reliable. Willow oyster scales have mites, ladybugs, parasitic wasps and parasites and other natural enemies.
