Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Adenia lobata - mosaic.
• Passiflora edulis - mosaic, malformed leaves, ringspots.
• P. foetida - mosaic, mottle, vein yellowing.

Transmission

Transmitted by a vector; an insect; Aphis gossypii, A. spiraecola; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation; not transmitted by seed.

Geographical distribution

Spreads in Cote d'Ivoire.

Experimental host range

Several (3-9) families susceptible.

Diagnostically susceptible host species and symptoms

• Chenopodium amaranticolor - faint chlorotic local lesions; not systemic.
• Cassia occidentalis - systemic ringspotting.
• Phaseolus vulgaris cv. Triomphe de Farcy - chlorotic spots then systemic vein necrosis.
• Passiflora edulis f. flavicarpa - systemic vein yellowing, epinasty, mottling, spotting, ringspotting.
• P. foetida - vein yellowing, then spotting and mosaic.
• P. quadrangularis - death of young plants, older plants not infected.
