The ampeloviruses causing grapevine leafroll disease are transmitted by mealybug and soft scale insect vectors. Vector transmission of virus species in this complex occurs in a semi-persistent manner, with no current evidence of a strict vector-virus species specificity. However, only a limited number of studies have addressed questions such as virus-vector transmission efficiency, and there are no published studies on virus-vector molecular interactions. Here we present a summary of what is known about the vector transmission of grapevine-associated ampeloviruses. Because the management of grapevine leafroll diseases depends on a robust understanding of how these viruses are disseminated in vineyards, we also highlight research needs and knowledge gaps.
