Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Cucumis melo - leaf chlorosis and vein necrosis.
• Pisum sativum - leaf chlorosis.

Transmission

Transmitted by a vector; an insect; Myzus persicae; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation; not transmitted by contact between plants.

Ecology and control

Studies reported by Freitag and Milne (1970).

Geographical distribution

Spreads in China and the USA (California).

Experimental host range
