摘　　要：甘蔗白叶病(Sugarcane white leaf disease,SCWL)是一种由植原体寄居甘蔗韧皮部筛管引起并对甘蔗生产造成毁灭性破坏的检疫性病害。文章综述了SCWL的病症、致病植原体、传播途径和发病规律等;阐述了几种病原检测方法的应用前景,指出DNA生物传感器将发展成最简便高效且能实现大田实时评价的诊断方法;重点介绍了SCWL几种防控措施的应用情况和防控效果,指出利用传播虫媒体内共生微生物进行基因改造的共生控制方法将成为未来阻断SCWL病源传播研究的新方向。提出加强蔗区间引种、调种时对SCWL的检疫监测工作,并应根据各地气候环境条件采取有效的综合防控措施等建议,以避免SCWL植原体在蔗区间扩散蔓延,确保蔗糖产业的可持续稳定健康发展。Sugarcane white leaf disease(SCWL)caused by phloem-colonized phytoplasma is one of the most destructive quarantine diseases on sugarcane.This paper summarized disease symptoms,pathogenic phytoplasma,disease transmission and occurrence regularity.The application prospect of several pathogenic diagnosis methods were discussed in the paper,and pointed out that DNA biosensor would develop into the most convenient and effective tool for diagnosis of SCWL in field.Application and control efficiency of several SCWL control strategies were introduced.And the paper pointed out that using the genetically modified symbiotic microorganisms which came from transmitted insects to control the spread of SCWL will become the new research direction to prevent the spread of disease source.In addition,following suggestions were proposed to avoid the spread of SCWL phytoplasma between sugarcane planting areas and ensure the sustainable and healthy development of sugar industry:strengthening the quarantine and inspection of SCWL when import sugarcane materials and transport sugarcane cuttings between sugarcane planting areas,taking effective comprehensive prevention and control measures according to local climatic condition.
