Pepper ring spot disease is transmitted by which species of nematode?

Pepper ring spot disease is transmitted by Paratrichodorus minor species of nematode.
These are spread by aphids, and some are spread by seed or mechanically. Symptoms of viruses include mosaic patterns on leaves, leaf curling, fruit distortion, overall stunting of the plant, or death.
Pepper ringspot virus (PepRSV) becomes radially arranged around mitochondria, which are often distorted, and in cells infected with some TRV isolates, "X-bodies" largely composed of abnormal mitochondria and containing small aggregates of virus particles may be produced.
