水稻橙叶病自1978年在我国云南发现以来,近年在福建,广东和广西的一些地区亦有发生。研究表明,病害只能由电光叶蝉(Recilia dorsalis)传播;两种黑尾叶蝉和三种飞虱不能传播,汁液摩擦和带病土壤也不传病。病毒在电光叶蝉体内属增殖型。病株超薄切片在电镜下见到类似病毒的球状颗粒,直径约15nm,病害对四环素不敏感,因此认为我国水稻橙叶病的病原似应是病毒,而非类菌原体。
Since its discovery in Yunnan in China in 1978, rice orange leaf disease has also occurred in some areas in Fujian, Guangdong and Guangxi in recent years. Studies have shown that the disease can only be transmitted by the leafhopper (Recilia dorsalis); two kinds of leafhoppers and three planthoppers can not spread, juice friction and disease-free soil nor disease. The virus in the electro-optic cicada body is proliferative. Thin sections of diseased plants can see similar virus-like spherical particles under electron microscope. The diameter is about 15nm. The disease is not sensitive to tetracycline. Therefore, it is considered that the pathogen of rice orange leaf disease in our country should be a virus rather than a mycoplasma.
