自FAvvcEtt氏(1933)发现鳞(癞)皮病(psovosis)以来,至今已弄清的柑桔病毒病有20多种,查明的病毒也将近有20种。有人估计目前柑桔病毒病的种类可能达到三、四十种,而且有白渐增多的趋向。有些国家病毒病已成为限制柑桔业发展的主要因子。目前巴西发生的曲叶病(Leaf cnrl),几乎能使所有的柑桔品种感病。美国还报导有:由嫁接和蚜虫类(桔蚜、棉蚜、绉线菊蚜)传染的衰退病,嫁接和叶蝉(Scaphytopius nitridus)传染的顽固病(类菌质体),嫁接和木虱(Triofza eryfreae,Diaphorina citri)传染的青果病和黄梢病(yellow shoot,黄龙病)等,为世界性危害的柑桔病害。我国广东、福建、台湾的黄梢(龙)病,一直是对桠柑、蕉柑、甜橙等柑桔生产威胁性很大的病害。日本的温州蜜柑矮缩病
Since the discovery of psovosis by FAvvcEtt (1933), there have been over 20 citrus virus diseases so far identified and nearly 20 viruses identified. Some people estimate that the current type of citrus virus disease may reach three or forty species, and there is a gradual increase in the white trend. Virus disease in some countries has become a major factor limiting citrus industry development. Leaf cnrl, currently occurring in Brazil, affects almost all citrus species. The United States also reported the following: recession disease by grafting and aphids (Aphis gossypii, Aphis gossypii, Aphis gossypii), stubborn disease (plastid) of grafting and Scaphytopius nitridus infections, grafting and psylla (Triofza eryfreae, Diaphorina citri) infection of green and yellow shoot disease (yellow shoot, Huanglong disease), etc., is a worldwide harmful citrus disease. China’s Guangdong, Fujian, Taiwan’s tip (dragon) disease, has been on orange, banana, orange and other citrus production threatening disease. Japan’s Wenzhou citrus dwarf disease
