枣疯病传毒昆虫的研究,在一九七八年的九组不同昆虫接种传毒试验枣苗(连对照合计75株)中,于一九七九年六月发现了接中国拟菱纹叶蝉的传毒处理产生了典型疯苗一株。同时也说明,直接来自疯树上的虫体,不再另加吸毒措施,也可传毒。一九七九年又继续扩大重复了九种不同昆虫的传毒试验(连对照合计枣苗300株),一九八○年六、七月间,在五组中国拟菱纹叶蝉的重复处理中,就有三组共六株枣苗发展为典型疯株。两年来最高疯苗率为33.3%,平均疯苗率21.8%。潜育期约为一年。同时将发病枣苗及传毒后虫体唾腺切片分别用电子显微镜观察,均明显存在多量的典型类菌原体,对照则无。因此,充分证实了中国拟菱纹叶蝉是枣疯病传毒昆虫。
Jujube mad poisoning insect research, in nine groups of nine different insecticide inoculation toxicity test jujube (in 1978, a total of 75), in June 1979 found that China plans to diamond Leafhopper poisoning produced a typical seedlings. At the same time also shows that the worm directly from the tree, no longer add another drug-taking measures, but also poisoning. In 1979, we continued to expand and repeat the experiment on the transmission of nine different insects (even with the control of a total of 300 jujube seedlings). In June and July of 1980, repeats of the five Chinese moth leafhoppers Processing, there are three groups of a total of six jujube seedlings developed into a typical crazy strain. The highest rate of mad seedling in two years was 33.3% and the average rate of mad seedling was 21.8%. The incubation period is about one year. At the same time, the incidence of jujube seedlings and transmitted parasite salivary glands were observed by electron microscopy, were clearly large amounts of typical mycoplasma, but no control. Therefore, it has been fully confirmed that the Chinese moth leafhopper is a jujube mad virus poisoning insects.
