角倍蚜Schlechtendalia chnensis(Bell)在胚后发育过程中雄性蚜脱皮3次,雌性蚜脱皮4次。随虫龄增加,虫体缩短,呈负生长。雄性蚜胚后发商历期较雌性蚜短1～2天。雌性蚜仅具1个卵巢管,管内仅具1个卵。此卵于性母4龄时已形成,并在雌性蚜胚后发育中迅速生长。卵特大,几乎占性成熟雌性蚜胸腹部体腔的大部分,卵壳膜质化。卵受精后在雌性蚜体内进行胚胎发育,最后干母以若蚜形式被产出,为一种卵胎生。本文最后还讨论了雌性蚜生殖方式,并与性母的生殖方式进行了比较。
The male aphid Schlechtendalia chnensis (Bell) peeled three times during embryo development and the female aphid peeled four times. With the increase of insects, parasites shorten, showed negative growth. Male aphids embryos traders period shorter than female aphids 1 to 2 days. Female aphids have only one ovary tube with only one egg in the tube. This egg has formed at the 4th instar of the sexual mother and grows rapidly in the post-embryonic development of female aphids. Egg is very large, accounting for almost the majority of mature female aphids chest and abdomen body cavity, egg shell membranous. After fertilization, the embryo develops in the female aphid. Finally, the dried stem is produced as aphid in the form of an ovum. At the end of this article, the reproductive methods of female aphids were also discussed and compared with the female reproductive methods.
