| 摘 要： | 调查了云杉阿扁叶蜂不同食叶强度时青海云杉的侧枝、胸径生长量，建立了针叶损失率与虫口密度、侧枝生长量、胸径生长量相对损失率之间的相关数学模型，级方差分析和多重比较划分了受害等级，为指导防治提供了依据。

| Abstract: | he related mathematic model between the loss rate of the needles and insect density,offshoot increment and relative loss rate of diameter breast high increment is established after the investigation on increment of offshoots and diameter breast high of Picea crassifolia Kom.in different degrees of needle loss caused by Acantholyda piceacola. Thus the scientific basis for the control of the pest is provided. |
