摘　　要：肚倍是一种重要的五倍子。肚倍蚜各世代都行卵胎生,两性生殖出现在春季。迁移蚜体内各卵和胚胎发育整齐,生殖期短;除雌蚜只生殖1头无生殖历期外,其余各无翅虫型体内各卵和胚胎渐次发育、渐次成熟、渐次产出,生殖期长。瘿内世代生殖量大;瘿外世代生殖量小,无翅侨蚜更小。除干雌未观察外,其他各虫型的个体初产出时均有一层软膜包被,脱膜后才能正常活动。迁移蚜生殖特性的利用于肚倍生产的关系极为重要。The Du-ensiform gall caused by Du-ensiform gall aphid, Kabu-ragia rhusicola, plays an important role in the production of Chinese gallnut. The aphid breeds ovoviviparously in all generations in its life history and reproduces sexually in spring. All the embryos of each migrant in spring and in summer grow mature simultaneously, so their reproductive period is quite short, while those of the wingless parthenogenetic females develop gradually and are produced gradually, thus the period is quite long. The fundatrix and the wingless fundatrigeniae breed in large numbers; two forms of migrants fewer; and the wingless alienicolae even fewer; while the females only one. The offspring of each generation is wrapped by a soft membrane when they are just born, except that the fundatrigeninae can not be observed, the young can be living after the membrane falls off. The reproduction characteristics of migrants are of great significance in production of Du-ensiform gall.
