| 摘 要： | 角倍由角倍蚜Schlechtendaliachinensis（Bell）寄生在盐肤木RhuschinensisMill和滨盐肤木R.chinensisvar．raxburghii（DC）Rehd．叶上致瘿而形成，约占五倍子总产量的80％。藓圃上越冬若蚜和盐肤木林中角倍的分布均属聚集分布。影响越冬若蚜和角倍聚集度的主要生态因子分别为藓长势、湿度、光照和树与藓的距离、风向、风速。于母和雏倍分布在盐肤木和滨肤木的第5～11片叶上，其中7～9片叶上干母数和雏倍数超过50％。干母数与雏倍数存在着显著的线性关系。盐肤木上：y1=3.3394＋0.7662x1，r1=0．9994**滨盐肤木上：y2=3.6707＋0.7431x2，r2=0.9894**

| Abstract: | The horned gall is caused by horned gall aphid, Schlechtendalia chinensis (Bell), which amounts to about 80 Percent of the total output of the chinese gall. The overwintering nymph aphids on Plagiomnium maximoriczii (Lindb.) T. Kop. and the horned galls on Rhus chinensis Mill.and.R chinensis var. raxburghii (DC)Rehd. belong to gathering distribution The fundatrices and young horned galls are on the 5th - 11th leaves of R chinensis Mill. and R chihensis var. raxburghii (DC) Rehd.and above 50% on the 7th -9th's.There is an apparent linear relahonship between the fundetrix number and the littie horned gall's. The equation is:on R chinensis: y1=3.3394 0.7662x1, r1=0.9994* * on R chinensis var. raxburghii: y2=3.6707 0.7431x2, r2=0.9894 |
