五倍子是一种重要的化工原料,主产中国。其中,由角倍蚜Schlechtendalia chinensis(Bell)所致的角倍分布最广,产量约占五倍子总量的80％。每年春,角倍蚜从冬寄主迁飞到夏寄主(结倍寄主)上。夏寄主上春迁蚜(性母)数量的多少,直接影响角倍产量。日本高木五六氏和我国唐觉教授等曾对春迁蚜的迁飞进行过观察,并指出:自然迁飞发生在晴天,对迁飞时的气候状况也作过记载。为对其迁飞规律有所认识,笔者于
Chinese nutgall is an important chemical raw material, mainly produced in China. Among them, the angular doubling distribution caused by Schlechtendalia chinensis (Bell) is the most widely distributed, accounting for about 80% of the total gallnut. Spring each year, hornworm aphids migrate from the winter host to the summer host (knot times host). Summer host on the spring aphids (sex mother) number, a direct impact on the number of times the output. Observations on the migration of spring aphids were made by Japan’s Takagi Wujiu and Chinese professor Tang Jue and pointed out that the natural migration took place on a sunny day and the climatic conditions at the time of migration were also recorded. In order to know the rules of its migration, I at
