南方水稻黑条矮缩病研究进展

南方水稻黑条矮缩病是21世纪初在我国华南地区首先发现的经远距离迁飞性害虫白背飞虱Sogatella furcifera传播的一种新的水稻病毒病,在发现后的十多年间发生面积不断扩大,危害逐年加重,成为我国和越南及周边国家重要水稻病害。迄今,有关该病害的研究取得了显著进展,本文综述了该病害的发生历史、病原特征及致病机理、病毒传播及流行规律和测报及防控技术,以期为该病害的深入研究和持久控制提供参考。

Advances in the researches on the southern rice black-streaked dwarf disease

Southern rice black-streaked dwarf disease is a new viral disease infecting rice plants, which is transmitted by long-distance migratory white-backed planthopper, Sogatella furcifera. Since its discovered in this century, this disease expanded the occurrence area and increased the damage of rice year by year, and became the most harmful virus disease in China, Vietnam and neighboring countries. In the last decade, remarkable progress has been made in the study of this disease. In this paper, the occurrence history, pathogen characteristics and pathogenesis, virus transmission and epidemic, disease prediction, disease prevention and control technology are reviewed in this paper. We hope to provide references for further investigating and lasting control of this disease.
