In recent years, Sri Lankan cassava mosaic virus (SLCMV), a begomovirus (genus Begmovirus, family Geminiviridae) causing cassava mosaic disease in Asia, poses serious threats to cassava cultivation in Asia. However, the transmission of SLCMV in the areas into which it has recently been introduced remain largely unexplored. Here we have compared the transmission efficiencies of SLCMV by three widely distributed whitefly species in Asia, and found that only Asia II 1 whiteflies were able to transmit this virus efficiently. The transmission efficiencies of SLCMV by different whitefly species were found to correlate positively with quantity of virus in whitefly whole body. Further, the viral transmission efficiency was found to be associated with varied ability of virus movement within different species of whiteflies. These findings provide detailed information regarding whitefly transmission of SLCMV, which will help to understand the spread of SLCMV in the field, and facilitate the prediction of virus epidemics.

三种木虱烟粉虱烟粉虱复合物的斯里兰卡木薯花叶病毒的差异传播。

近年来,斯里兰卡的木薯花叶病毒(SLCMV)是一种在亚洲引起木薯花叶病的传病病毒(Begmovirus属,双子病毒科),对亚洲的木薯种植构成了严重威胁。但是,SLCMV在最近被引入的地区中的传播仍未得到充分探索。在这里,我们比较了亚洲三个分布广泛的粉虱种对SLCMV的传播效率,发现只有Asia II 1的粉虱才能够有效传播这种病毒。发现不同粉虱种类对SLCMV的传播效率与粉虱整个体内的病毒数量呈正相关。此外,发现病毒的传播效率与病毒在不同种类的粉虱中的移动能力有关。
