摘　　要：木薯是重要的经济与粮食作物,由于其出色的耐旱、耐贫瘠、易种植等特性,在全球热带和亚热带地区广泛种植。木薯在生长过程中会受到多种病虫害的威胁,其中分布最广、危害最严重的是木薯花叶病毒(Cassava mosaic virus,CMV)。CMV主要通过带毒茎秆和媒介昆虫烟粉虱传播,可以造成木薯叶片出现斑驳花叶、卷曲甚至枯萎,植株整体长势衰弱,导致木薯产量下降,严重威胁木薯生产。我国和东南亚木薯产区此前并没有CMV发生和危害的报道。可近年来,斯里兰卡木薯花叶病毒(Sri Lanka cassava mosaic virus,SLCMV)在东南亚地区广泛传播,已经成为该地区木薯生产的主要病害,对我国的木薯生产也构成了重大威胁。本文围绕SLCMV在亚洲的发生、传播机制和防治策略展开了讨论,以期为防控SLCMV在我国的危害提供参考。Cassava(Manihot esculenta Crantz)is an important economic and food crop in Latin America,Africa and Southeast Asia.Because of its excellences in drought and barren tolerance,cassava is widely cultivated in tropical and subtropical regions of the world.Cassava mosaic virus(CMV)is one of the most widespread diseases that threaten cassava production.Since cassava is a vegetatively propagated crop,CMV is mainly transmitted by infected planting material(stakes).Nevertheless,CMV is also transmitted by various species of the Bemisia tabaci(Gennadius)whitefly complex(Hemiptera:Aleyrodidae).Previously,there have been no reports of CMV occurrence and damage in cassava producing areas in China and Southeast Asia.However,in recent years,Sri Lanka cassava mosaic virus(SLCMV)has been widely spread in Southeast Asia.Now,it has become the main disease of cassava production in this region,and also poses a major threat to cassava production in China.This paper will discuss the occurrence,transmission and prevention strategies of SLCMV in Asia.It may provide reference for the prevention and control of SLCMV in China.
