摘　　要：角倍蚜Schlechtendalia chinensis Bell可刺激盐肤木(Rhus chinensis Mill)叶片组织形成虫瘿。本研究通过对虫瘿形成过程中可溶性蛋白、保护酶、丙二醛和脯氨酸等生理指标的测定,分析虫瘿形成对盐肤木的影响。结果表明:在虫瘿发育的不同时期,除可溶性蛋白在有虫瘿叶片与无虫瘿叶片存在一定差异外,其他各项生理指标的差异均不显著,表明虫瘿形成未对植株造成严重氧化性损伤及脂质膜的破坏,但对盐肤木物质代谢存在一定程度的扰动。推测盐肤木通过形成虫瘿抵御蚜虫的攻击,而角倍蚜则从虫瘿中获得稳定的营养来源,二者在长期进化过程中可能已经形成了互利关系。Horned-galls on Rhus chinensis Mill is induced by galling aphid, Schlechtendalia chinensis Bell. This research judged the effects of gall formation on R. chinensis according to the test of total soluble protein, protective enzymes, malonaldehyde and free proline. All results indicates that during three important periods of gall formation, with the increase of aphid individual, there was no significant difference in all physiological indexs above except the total soluble protein content which showed slight variation. It is probably that the galling aphids may disturb the substance metabolism of its host plants, but do not make serious oxidative damage or injury of lipid membrane. Gall might acts as a defense structure which reduces the damage of aphids and aphids may get nutrition from it. Furthermore, a mutually benificial relationship might exist between the gall-forming aphid and its host plant.
