落叶松球蚜;种群数量;消长规律;树冠层次分布
摘  要:
对落叶松球蚜发生林分的调查结果表明:落叶松球蚜种群数量的时间发生序列为6月份种群数量最高,随后逐月减少,到9月份停止活动;在树冠层次分布上,个体主要处于树冠上层,中层次之,下层最少。在进行化学防治落叶松球蚜时,应重点在树冠上中层施药,可有效提高防治效果。

摘  要:
The survey results of forest stand with Adelges laricis indicated that the time series of Adelges laricis population was as follows: the highest numbers appeared in June,with the monthly decrease,activities were stopped in september.Canopy level distribution showed that the individuals were mainly in the upper layer,middle layer took the second place,and the least was in the lower layer.The chemical prevention emphasis of Adelges laricis was pesticide application in upper and middle layer,which can effectively improve the control effect.
