Nomenclature

Acronym

TeaMV

ICTV decimal code

57.0.1.T.081

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Dipsacus fullonum - vein clearing, chlorotic mottling and malformed filiform leaves.

Transmission

Transmitted by a vector; an insect; Macrosiphum rosae, Myzus persicae; Aphididae. Not transmitted by Rhopalosiphum padi, Macrosiphum avenae. Transmitted in a non-persistent manner. Virus not transmitted by mechanical inoculation.

Geographical distribution

Spreads in the USA (California).

Experimental host range

Few (<3) families susceptible. Experimentally infected plants mostly show leaf mottling and malformation.

Diagnostically susceptible host species and symptoms

• Dipsacus fullonum, Scabiosa atropurpurea - systemic vein clearing, then mottling and malformed leaves.

Diagnostically insusceptible host species

Cucurbita pepo, Beta vulgaris, Nicotiana tabacum, Cucumis sativus.
