摘　　要： 由斐济病毒属(Fijivirus)暂定新种南方水稻黑条矮缩病毒(Southern rice black-streaked dwarf virus,SRBSDV)引起的水稻矮缩病,自2001年在广东省阳西县被发现以来,已迅速扩散至我国南方广大稻区。2009年,该病害在我国南部及越南晚季稻上暴发成灾,造成严重的产量损失。本文简介了该病害的症状、危害特点、病原病毒及其传毒介体特征,对其发生趋势进行了讨论,提出了以秧苗期治虫为重点的病害防控应急措施。 A rice dwarf disease caused by a proposed novel Fijivirus species, the Southern rice black-streaked dwarf virus, spread rapidly throughout the southern part of China after it was first observed in 2001, in Yangxi county, Guangdong Province. The disease outbreak occurred in summer 2009 and caused serious yield losses in southern China and Vietnam. The authors described the disease symptoms, occurrence characteristics, and the characters of pathogenic virus and its vectors. The disease epidemic trend and control strategy was also discussed.
