棉花曲叶病毒(Cotton leaf curl virus,CLCuV)是我国的进境检疫性有害生物,严重危害棉花生长,在巴基斯坦和印度的棉花产区已造成毁灭性灾害。该病毒主要由烟粉虱传播,寄主范围广泛。2006年在广东首次发现棉花曲叶病毒(CLCuV)入侵我国危害朱槿,2010年有报道证实CLCuV已侵染广西南宁试验田的棉花。我国是棉花生产大国,该病毒一旦扩散传播到棉花主产区,后果将不堪设想。本文对CLCuV的变异、国内外分布和流行趋势、影响棉花曲叶病流行的因素、病毒对棉花的品质和产量的影响及病害治理等方面进行综述,并探讨了棉花曲叶病毒研究存在的问题及有效防止该病毒传播和扩散的措施。
Cotton leaf curl virus (CLCuV) is a quarantine pest of entry in China, which seriously endangers cotton growth and has caused devastating damage in the cotton producing areas in Pakistan and India. The virus is mainly transmitted by the whitefly, host a wide range. In 2006, it was first discovered in Guangdong that cotton leaf curl virus (CLCuV) invaded China to harm Hibiscus. In 2010, it was reported that CLCuV had invaded the cotton in the experimental field of Nanning, Guangxi. China is a big producer of cotton. Once the virus spread to the main cotton producing areas, the consequences would be disastrous. In this paper, the variation of CLCuV, the distribution and trend at home and abroad, the factors affecting the epidemic of cotton leaf curl, the effects of the virus on the quality and yield of cotton and the disease control were reviewed, and the problems in the study of cotton curl virus were discussed And effective measures to prevent the spread and spread of the virus.
