Grapevine leafroll associated virus-3 (GLRaV-3) and Grapevine leafroll associated virus-5 (GLRaV-5), two members of the genus Ampelovirus associated with grapevine leafroll disease, were transmitted by the mealybug Planococcus ficus and the soft scale insect Ceroplastes rusci from infected to healthy vines under experimental conditions. The efficiencies of transmission of GLRaV-3 and GLRaV-5 by P. ficus were 23.3 and 8.3%, respectively, and by C. rusci were 3.3 and 1.7%, respectively. Juvenile instars of P. ficus were more efficient in transmission of the viruses than adult females. This is the first report of the ability of C. rusci to transmit these viruses to grapevines.
葡萄卷叶相关病毒3（GLRaV-3）和葡萄卷叶相关病毒5（GLRaV-5）是与葡萄卷叶病相关的毛形病毒属的两个成员，在实验条件下，粉蚧褐软蚧和软蚧蜡蚧可将其从受感染的葡萄藤传播到健康的葡萄藤上。褐软蚧传播GLRaV-3和GLRaV-5的效率分别为23.3%和8.3%，蜡蚧传播的效率分别为3.3%和1.7%。褐软蚧的若虫在传播病毒方面比成年雌虫更有效。这是关于蜡蚧将这些病毒传播到葡萄藤上能力的首次报道。
