ICTV decimal code

29.0.3.0.037

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Ageratum conyzoides, Zinnia elegans, Capsicum annuum, Datura stramonium, Nicotiana tabacum - leaf curling.
• Lycopersicon esculentum - leaf curling, yellow dwarfing.
• Lonicera japonica - vein yellowing.

Transmission

Transmitted by a vector; an insect; Bemisia tabaci; Aleyrodidae. Transmitted in a persistent manner. Virus lost by the vector when it moults; 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.

Geographical distribution

Probably distributed worldwide (in tropical and subtropal regions).

Experimental host range

Several (3-9) families susceptible.

Diagnostically susceptible host species and symptoms

• Datura stramonium, Nicotiana glutinosa - systemic leaf curling.
• Lonicera japonica - systemic vein yellowing.
• Lycopersicon esculentum - systemic yellow dwarfing, leaf curling.

Diagnostically insusceptible host species

Cassia tora, Phaseolus vulgaris, Vicia faba, Vigna unguiculata ssp. sesquipedalis, Solanum nodiflorum.
