Dioecious holocyclic

Primary hosts: Ribes spp (like redcurrant, blackcurrant).
Secondary hosts: Asteraceae: Lactuca (lettuce), Chicorium (chicory and endive), Solanaceae: Nicotiana tabacum (tobacco), Petunia (petunia) and Scrophulariaceae: Euphrasia (eyebright), Veronica (speedwell).

N. ribisnigri is the dominant species in open field crops of lettuce
This species manifests signs of resistance to insecticides.

Agronomic impact

N. ribisnigri does not cause significant direct damage: hardly any colour change to leaves and just slight deformation with margins undulating. Conversely the indirect damage due to the serious tainting produced makes harvests unmarketable.
It transmits the cauliflower mosaic (CaMV) and cucumber mosaic viruses (CMV) but not that of lettuce mosaic (LMV), or very little.
