作者等在1978年以9种不同昆虫接种传枣疯病的实验中(连对照共枣苗75株),于1979年6月发现直接采自疯树的中国拟菱纹叶蝉(Hishimonideschinensis Anufriev)在健康根蘖枣苗上传染了典型疯苗一株。1979年又继续扩大重复了9种不同昆虫的传病实验(连对照共枣苗300株),到1980年6、7月间,在五组中国拟菱纹叶蝉的重复处理中,有三组共六株枣苗出现典型疯株。两年来平均传病率为21.8%。潜育期10～12个月。将发病枣苗及传病的中国拟菱纹叶蝉唾腺超薄切片分别用电子显微镜观察,均明显存在多量典型的类菌原体(MLO),对照则没有。因此,初步证实中国拟菱纹叶蝉能传枣疯病。
In 1978, an experiment was conducted in which 9 different insects were used to inoculate jujuba (with a total of 75 juveniles in total). In June 1979, Hishimonideschinensis Anufriev, Zao jujube seedlings in the health of the typical infected with a strain of mad. In 1979, we continued to expand and repeat the disease experiment of 9 different insects (even with a total of 300 jujube shoots). Between June and July 1980, there were three groups A total of six jujube seedlings appear typical crazy. The average prevalence rate in two years was 21.8%. Potential incubation period of 10 to 12 months. The incidence of jujube and disease-borne disease in China Schiller leafhopper salivary gland ultra-thin sections were observed by electron microscopy, there are clearly a large number of typical mycoplasma (MLO), the control did not. Therefore, preliminary confirmed that China can be linked Ryan leafhopper Zajian Biao disease.
