Rose is the primary host for both species. Potato aphid disperses to a wide variety of herbaceous plant hosts in summer.
Aphids are very commonly associated with roses, particularly late in the season. Infestations concentrate around new shoots and flower buds.
During outbreaks these insects can reduce flower nacrosiphum and may even kill buds.
Rose Aphids – Control and Identification
Aphids may also feed on flower petals after bud break, causing losses in flower quality. Potato aphids disperse to other plants during summer and may be found on a very wide range of host plants during this period.
Nightshade family hosts, such as tomatoes, are favored during this time but potato aphid can be found feeding on most vegetables, a wide variety of flowers, on common weeds such as pigweed and sowthistle, and small fruits.
Winged stages of the late summer generations disperse back to rose and reproduce, contributing greatly to late season outbreaks. Both pink and green forms of the potato aphid are common and this insect may also be a serious greenhouse pest.
Rose aphid apparently restricts feeding to rose through out the year.

It produces only green forms that may be winged or wingless, macrospihum latter dispersing to new plantings. General aphid predators, such as lady beetles and syrphid flies, as well as parasitic wasps commonly feed on rose aphids.
These usually keep populations under fair control, although aphid outbreaks frequently occur during spring and fall when biological controls are not highly active. Rose aphids are quite delicate, so hosing plants with a strong jet of water syringing can kill and dislodge many.
Pruning prior to bud break can remove many of the eggs that overwinter on canes. Most general-use insecticides, including the “rose systemics” Disystonare usually effective.
Rosxe sprays of insecticidal soaps or horticultural oils are also effective.
