摘　　要：角倍是角倍蚜寄生在盐肤木上形成的虫瘿,其形态是倍蚜分类的重要依据。文章观察记录角倍形态特征,包括形状、着生位置、成熟时期、大小、壁厚和重量等,对数据进行统计分析,观察角倍蚜主要形态特征,检测是否是致瘿蚜的主要形态特征变异引起倍子形态的多样化。结果发现角倍形态多样性较高,其形状主要有圆形、长形、扁形和花形;按分叉情况,有两叉和三叉;大多数着生于叶总轴基部第1、2对小叶间;角倍成熟期为9月中下旬到10月下旬;角倍大小、壁厚和重量均有显著差别;角倍形态差异很大,但通过显微镜观察发现形成不同形状角倍的角倍蚜形态特征(头部、喙、触角和翅)无明显差异,说明角倍蚜形成倍子形态的多样化。The horn galls are formed by the horn gall aphid Schlechtendalia chinensis on its host plant Rhus chinensis, and named for its horn-like shape, which is important characteristics for the identification of gall aphids. We observed and recorded the morphological characteristics of horn galls, including shape, position on the tree, maturity period, size, wall thickness and weight, meanwhile analyzed the data. We observed the morphological characteristics of horn gall aphids, e. g. head, antenna, rostrum and wings, to examine whether the morphological characteristics of horn gall aphids result in the variation of horn galls. We found that the horn galls had higher morphological diversity, and the shape of galls included round, long, flat and flower-like as well as two or three divisions from the root stems of leaf. Most were formed between the first and second pair of leaflets at the base of the common leaf axis. The mature period of horn galls was from mid-late September to late October. There were significant differences in size, wall thickness and weight of horn gall. The morphology of horn galls is very variable, but the main morphological characteristics of the horn gall aphids, e. g. anal plate, rostrum, antennae and wings have no obvious difference by microscope observation, which show the morphological diversity of horn galls formed by the horn gall aphid Schlechtendalia chinensis.
