Transmission of leafhopper a virus, vertically through eggs and horizontally through maize in which it does not multiply.
Leafhopper A virus (LAV) multiplies in the leafhopper Cicadulina bimaculaata but not in maize plants colonized by the insect. The virus is transmitted vertically through insect eggs but not sperm or horizontally in insects feeding on plants in which it circulates transiently after being injected by coinfesting virus-infected C. bimaculata. Thus the maize plant is a transitory reservoir of LAV and the plant can be looked upon as a circulative but nonpersistent vector of an insect virus.
