Nomenclature

ICTV decimal code

79.0.P.DE.39

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Rubus parviflorus - irregular leaf ringspotting and oak leaf patterns.

Transmission

Transmitted by a vector; an insect; Macrosiphum (Oestlundia) davidsonii, M.(O.) maxima and Amphorophora parviflori; Aphididae. Not transmitted by Amphorophora agathonica. Virus not transmitted by mechanical inoculation; transmitted by grafting; not transmitted by contact between plants; not transmitted by seed; not transmitted by pollen.

Geographical distribution

Spreads in Canada.

Experimental host range

Few (<3) families susceptible. Experimentally infected plants mostly show ringspots and oak leaf markings.

Diagnostically susceptible host species and symptoms

• Rubus parviflorus - ringspot and oak leaf markings.
• Rubus idaeus - faint chlorotic markings.
• R. occidentalis - diffuse mottle.
• R. henryi - chlorotic leaf spots.
