小麦丛矮病是我国小麦的重要病害之一,通过灰稻虱(Laodelphaz striatellus Falén)在病株上吸毒和在介体内注射病毒证实能传本病。除灰稻虱外,是否还有别的介体?灰稻虱的传毒特性又怎样?本文是1979～1981年对这方面研究的总结。材料和方法毒源是在1979年8月从浙江省临安县上溪公社高山夏播小麦典型病株上,用无毒灰稻虱反复饲毒和接种所得的病株。虫源是在杭州室内分离的灰稻虱无毒虫。供试寄主用感病品种小麦(Triticum aestivum L.)浙麦1号,二棱裸大麦(Hor
Wheat bushy dwarf disease is one of the most important diseases of wheat in our country. It is proved that the disease can be transmitted to the infected plants by Laodelphaz striatellus Falén and the injection of virus in the medium. In addition to the ash louse, are there any other mediators? What are the characteristics of the transmission toxicity of the ash louse? This article is from 1979 to 1981, a summary of this research. MATERIALS AND METHODS Toxicity was obtained from the typical strain of Alpine summer sowing wheat on Shangxi Commune, Lin’an County, Zhejiang Province in August 1979 by repeated inoculation and inoculation of innocuous gray flies. Insect source is a non-toxic insect pest isolated in Hangzhou indoor. Hosts used the susceptible varieties of wheat (Triticum aestivum L.) Zhejiang wheat 1, bark naked barley Hor
