Several mealybug species are vectors of grapevine leafroll-associated viruses (GLRaV), which cause the economically important grapevine leafroll disease in grape-producing regions worldwide. The mealybug Ferrisia gilli Gullan is a new pest of grapevines in El Dorado County, located in the Sierra Foothill wine-growing region of California. GLRaV species 1, 2, 3, and 4LV have been detected in vineyards with symptomatic vines in the Sierra Foothills. We conducted controlled virus acquisition and transmission experiments using source vine accessions infected with different combinations of GLRaV. We determined that F. gilli acquired GLRaV 1, 2, 3, and 4LV, and transmitted GLRaV-3 and GLRaV-4LV to uninfected recipient vines. Like numerous other mealybug species, in addition to causing direct damage to vines, F. gilli poses a threat to the grape industry as a vector of economically damaging viruses.
几种粉蚧是葡萄卷叶相关病毒（GLRaV）的传播媒介，这些病毒在全球葡萄产区引发了具有重要经济影响的葡萄卷叶病。粉蚧费氏吉尔粉蚧（Ferrisia gilli Gullan）是位于加利福尼亚州内华达山麓葡萄酒产区的埃尔多拉多县葡萄藤的一种新害虫。在位于内华达山麓有症状葡萄藤的葡萄园里已检测到GLRaV 1、2、3和4LV型病毒。我们使用感染了不同GLRaV组合的源葡萄品种进行了受控病毒获取和传播实验。我们确定费氏吉尔粉蚧获取了GLRaV 1、2、3和4LV型病毒，并将GLRaV-3和GLRaV-4LV型病毒传播给未感染的受体葡萄藤。与许多其他粉蚧物种一样，除了对葡萄藤造成直接损害外，费氏吉尔粉蚧作为具有经济破坏性病毒的传播媒介，对葡萄产业构成了威胁。
