Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Capsicum annuum, C. frutescens - mottle, leaf shape malformation.
• Datura stramonium - mosaic, fruit malformation, with spine suppression.
• Lycopersicon esculentum - mosaic and necrotic or chlorotic spots and streaks.
• Petunia × hybrida - mottle and mosaic.

Transmission

Transmitted by a vector; an insect; Aphis gossypii, A. spiraecola, Myzus persicae, Toxoptera citricidus; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation; transmitted by grafting; not transmitted by contact between plants.
