小麦丛矮病是一种由灰飞虱(Laodelphax striatellus Fallen)传播的病毒病,有关此病的发病规律已有报道,其病原是杆状病毒。把提取的小麦丛矮病毒人工注射于健康灰飞虱体内,令其在健康麦苗上取食,则麦苗可发生典型的丛矮病症状。关于小麦丛矮病毒的寄主植物,陕西省农科院植保所和中国科学院微生物研究所都曾做过研究。我们在此基础上进行了较广泛的寄主范围测定,现将实验结果报告如下。 Cercosporides dwarf disease is a viral disease transmitted by Laodelphax striatellus Fallen. The pathogenesis of this disease has been reported, and its origin is baculovirus. The extracted wheat dwarf virus was artificially injected into healthy body-hoppers so as to feed on the healthy wheat germ. The typical symptoms of bushy dwarf disease may occur in wheat germ. On the host plants of wheat bushy stunt virus, Institute of Microbial Protection of Shaanxi Academy of Agricultural Sciences and Chinese Academy of Sciences have done research. Based on this, we conducted a wider range of host determination, the experimental results are reported as follows.
