水稻病毒,诸如水稻矮缩病毒,(Rice-gall dwarf virus)水稻瘤矮病毒(Ric-egall dwarf virus)和水稻短暂性黄化病毒(Rice transitory virus),已知都由其叶蝉介体传播到奇主植物上,而不能用其它方法进行机械传播。这些病毒的侵染力只能通过人工注射少量病毒悬浮液到介体叶蝉腹腔内进行测定。用这种方法而获得 Rice viruses such as the Rice-gall dwarf virus, Ric-egall dwarf virus, and Rice transitory virus are all known to be transmitted by their leafhopper mediators To the main plant, but can not use other methods of mechanical transmission. The infectivity of these viruses can only be determined by artificially injecting a small amount of the virus suspension into the abdominal cavity of a mediator leafhopper. Obtained in this way
