| 摘 要： | 根据野外调查观察和实验测定结果，论述了五倍子蚜虫－盐肤木树－藓类植物生物群落的特性。五倍子虫瘿是该群落的产物，是倍蚜虫与盐肤木树木、藓类植物共生的产物。群落中五倍子蚜虫转主寄生的主要原因是由蚜虫食物的营养质量决定的，秋天当盐肤木叶子含氮量低于１．２％时，倍蚜便发生迁飞，春天当鲜类植物含氮量低于１．１％时，倍蚜便回到迁到盐肤木树上。

| Abstract: | The paper deals with the biological and ecological characteristics of aphid (horned gallnut aphid)-tree (Sumac tree)- moss biocommuniy. Horned and bellied gallnut are important forest side - line products from mutualism between sumac tree, moss and aphid (gallnut aphid). The host alternation of horned gallnut aphid mainly relies on nitrogen cnd in host plants. Ih Antumn, when nitrogen content in the leaves of sumac tree is below 1.2%, the horned galinut aphid begins to migrate.And in Spring, when the amount of nitrogen is below 1.1%, the aphid migrates back to the tree. |
