Nomenclature

Acronym

SLPMV

ICTV decimal code

57.0.1.T.076

Host range and symptoms

Natural host range and symptoms

Symptoms persist. Symptoms mottling.
• Passiflora edulis cv. flavicarpa - leaf mottling.

Transmission

Transmitted by a vector; an insect; Aphis craccivora, A. gossypii, A. spiraecola. Myzus persicae; Aphididae. Transmitted in a non-persistent manner. Virus lost by the vector when it moults; does not multiply in the vector; not transmitted congenitally to the progeny of the vector; transmitted by mechanical inoculation; transmitted by grafting.

Geographical distribution

Found, but with no evidence of spread, in Sri Lanka.

Experimental host range

Several (3-9) families susceptible. Experimentally infected plants mostly show chlorotic/necrotic lesions, chlorotic mottle/mosaic, leaf distortion, vein yellowing.

Diagnostically susceptible host species and symptoms

• Cassia occidentalis - systemic chlorotic mottle, mosaic and vein yellowing.
• Chenopodium album, C. amaranticolor, C. foetidum - chlorotic local lesions only.
• Chenopodium murale, C. quinoa - chlorotic mottle and mosaic of inoculated leaves only.
• Gomphrena globosa, Phaseolus vulgaris, Vigna unguiculata - necrotic local lesions only.
• Passiflora edulis cvs edulis and flavicarpa - systemic chlorotic mottle/mosaic with distortion (vein yellowing also in flavicarpa).
• P. mollissima - chlorotic mottle/mosaic and flecking, flower break.

Diagnostically insusceptible host species

Datura stramonium, Glycine max, Nicotiana debneyi, N. tabacum, Passiflora suberosa, Pisum sativum.

Maintenance and propagation hosts

Chenopodium quinoa, Passiflora edulis cv. flavicarpa, P. foetida.

Assay hosts (Local lesions or Whole plants)
