- A heteroecious species with Rosa (R. canina, R. glauca, R. villosa, R. multiflora) as primary host; colonies do not persist on the primary host beyond June, the aphids then migrating to secondary hosts, especially wheat (*) and barley, before moving on to the underside of leaves of maize.
- When present in great profusion, this species can cause direct damage. Most common and numerous species on maize at the beginning of the crop; the presence of colonies of 200 aphids on each plant at the 6-8 leaves stage is considered to be the economic injury threshold.
- This aphid is a vector of the maize mosaic virus (MMV) and the barley yellow dwarf virus (BYDV).
