<正>对盐肤木叶片的解剖分析后初步认为，角倍蚜选择盐肤木复叶叶翅作为寄生部位，是由盐肤木叶片的形态构造所决定的，叶翅的厚度是小叶的２．３倍。叶翅栅栏组织与海绵组织的比率只有小叶的１／５，角倍蚜干母寄生于叶翅的致倍效果明显好于小叶，寄生在小叶上角倍壁的厚度、平均重量均小于寄生于叶翅上的角倍，无叶翅或叶翅狭窄的滨盐肤木不宜作为角倍林的夏寄主树。角倍具发达的贮存组织和通气组织。角倍形成１月后，瘿壁的厚度停止增长，虽然以后近５个月内其直径增长十几倍，体积增长数百倍，但瘿壁厚度保持不变。

According to the results of observing and analyzing of gall and its host leaf structure of Rhus chinensis,it was found that the selectivity of Schlechtendalia chinensis on the position of host leaf was decided by the leaf structure of Rhus chinensis. The thickness of leaf-wings is 2. 3 times more than that of leaf-lets; the ratio of palisade tissue to spongy tissue was much different between them. There was only one fifth of leaf-wings to leaf-lets. The formation result of gall aphid on the leaf-wings was better than that on the leaf-lets. The horned gall hosted on the leaf-wings, with a thick gall-shell, is heavier than that on the leaf-lets. For these reasons, Rhus chinensis var. raxburghii with narrow and limited leaf-wings is unsuitable for plantation as a host tree. There was developed storage tissue and aerenchy- ma of horned gall; The shell thickness of the gall almost stopped growing one month later after the embryo gall has formed(in the middle of June) ,but the diameter and the volume of gall was going to increase in a high-speed until mature period (at the beginning of October).
