Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Beta vulgaris - yellowing, stunting.
• Lactuca sativa - severe stunting and chlorosis, severe necrosis of phloem tissue.
• Sonchus oleraceus - red or yellow interveinal colouration.

Transmission

Transmitted by a vector; an insect; Hyperomyzus lactucae, Myzus persicae, Macrosiphum euphorbiae; Aphididae. Principal natural vector(s): Hyperomyzus lactucae. Transmitted in a semi-persistent manner. Virus lost by the vector when it moults; not transmitted congenitally to the progeny of the vector; not transmitted by mechanical inoculation; not transmitted by contact between plants; not transmitted by seed.

Geographical distribution

Found, but with no evidence of spread, in the U.K. in Scotland.
