摘　　要：采取随机取样调查法，对大兴安岭新林、加格达奇和哈尔滨地区阿城市玉泉林场、宾县松林林场的不同林龄、林型和林木位置的落叶松上的松瘿小卷蛾（Cydia zebeana）危害进行调查发现：松瘿小卷蛾对落叶松幼龄林主梢危害严重，虫瘿在树冠中、下部的分布明显多于上部（P〈0．05），树冠各个方位的虫瘿分布无明显差异（P〉0．05）；林缘的虫瘿密度明显高于林内，混交林的虫瘿密度显著小于纯林（P〈0．05）。在大兴安岭，松瘿小卷蛾于不同直径的落叶松枝条上均呈聚集分布，而在哈尔滨地区则呈均匀分布，两地分别有86．1％和80．6％虫瘿分布在直径为0．40-1．19cm的枝条上。A survey was conducted to study the damage of Cydia zebeana Ratzeburg on larch trees of different forest ages, forest types and locations in Xinlin, Jiagedaqi of Daxing＇ anling, Yuquan Forest Farm of Acheng and Songlin Forest Farm in Binxian of Harbin by random sampling. C. zebeana mainly endangers the top of primary trunk of young trees. Gall number is significantly higher in the middle-low part than in the upper part of a crown, while there is no obvious difference in gall number between different orientations of the crown. The insect density on the edge of forest is markedly higher than that in forest, and the insect density in mixed forest is evidently lower than that in pure forest. C. zebeana in different diameter branches shows an aggregated distribution pattern in Daxing＇ anling and a uniform distribution in Harbin, and 86.1% and 80.6% of the galls distribute at a diameter interval ranging from 0.40 cm to 1.19 cm in the two areas respectively.
