五倍子蚜虫是我国重要的经济昆虫之一。由该类蚜虫寄生于漆树科盐肤木属树种叶上所致虫瘿即五倍子,含有高达70％的单宁。这种生物单宁及其衍生物倍酸、焦倍酸是医药、纺织印染、石油、化工、冶金、电子和航天等行业的重要原料。五倍子蚜系多态型,具翅的性母成蚜产生于冬寄主并于翌春迁飞到夏寄主上,完成繁衍和致瘿过程。了解和认识各种倍蚜性母蚜的形态,对倍蚜发生期,发生量的测报和冬寄主的判定具有重要意义。在已知的13种倍蚜中,只有角倍蚜Schlechtendallia chinensisBell。和倍蛋蚜Schlechtendallia peita Tsai & Tang。性母成蚜形态的记述,余均不详。本文新记述我们于1983—1984年在四川通过人工接种和树干上捕捉的5种倍蚜的性母成蚜形态,其模式标本均存四川省林科所。
Chinese gall aphids are one of China’s major economic insects. Parasitism caused by aphids such as gallnut, which is parasitic on the leaves of the tree tree of the tree family, contains up to 70% tannin. This biological tannin and its derivatives acid, acid is the focus of medicine, textile printing and dyeing, petroleum, chemical, metallurgy, electronics and aerospace industries, an important raw material. The gallnut aphid is a polymorphic, winged sexually mature female, which is produced by the winter host and relocated to the summer host in the next spring to complete the process of reproduction and proclivity. Understanding and understanding of aphids all kinds of double aphids morphology, the occurrence of the times aphids, the amount of the report and winter host decision is of great significance. Of the 13 known aphids, only Schlechtendalia chinensisBell. And Schlechtendallia peita Tsai & Tang. Sexual mothers into aphids morphological description, I have not known. This article describes the morphological characteristics of the sexual aphids of the five species of Aphis gossypii collected from artificial inoculation and tree trunks in Sichuan in 1983-1984. All the specimens were collected from the Forestry Branch of Sichuan Province.
