Wheat aphid propagated wheat yellow dwarf virus wheat aphid Valley Aphis gossypii (GPV), wheat aphid Aphis gossypii transmission Aphis gossypii (GAV). This article focuses on the preliminary results of the biological characterization of the G. graminearum (SG) transmission (GPV) strain and the M. gossypii (MA) transmission (GAV) strain. MATERIALS AND METHODS: The tested sources were GPV strain of Puhuang yellow in Shaanxi province and GAV strain of yellow dwarf virus in Hohhot, Inner Mongolia. The tested aphids were non-toxic aphid strain of wheat borer, North China No. 2 oats. Single-headed insecticide inoculation and poisoning treatment, handling aphids before
