CYVMV

ICTV decimal code

29.0.3.0.014

Host range and symptoms

Natural host range and symptoms

Symptoms persist and vary seasonally. Symptoms vein clearing, vein yellowing, thickening of veins and curling.
• Croton bonplandianus - vein clearing and yellowing, thickening of veins and leaf curling.

Transmission

Transmitted by a vector; an insect; Bemisia tabaci; Aleyrodidae. Transmitted in a persistent manner. Virus retained when the vector moults; does not multiply in the vector; not transmitted congenitally to the progeny of the vector; 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 India.

Experimental host range

Many (>9) families susceptible. Experimentally infected plants mostly show vein clearing, malformation, yellowing and thickening, leaf curling, enations and dark green veins.

Diagnostically susceptible host species and symptoms

• Croton bonplandianus - yellow vein.
• Beta vulgaris, Spinacia oleracea - vein thickening.
• Carica papaya, Lycopersicon esculentum, Phaseolus vulgaris - leaf curling.
• Raphanus sativus - curling and rolling of leaves.

Diagnostically insusceptible host species

Abelmoschus esculentus, Arachis hypogaea, Cucumis sativus, Euphorbia heterophylla, Vigna unguiculata.

Maintenance and propagation hosts
