Dioecious holocyclic, between rose bushes and Dipsacaceae or Valerianaceae.
Mainly anholocyclic on rose bushes in regions with mild climate.
Primary host: Rosa (rose bushes).
Secondary hosts: Dipsacaceae, occasionally other Rosaceae (Fragaria, strawberry, Pyrus, pear, Malus, apple, also Rubus, blackberry) and Valerianaceae.
In autumn the eggs are deposited on rose bushes, wild or cultivated varieties. In spring, eggs hatch and the larvae invade flower stems and the underside of leaves. A partial migration occurs during the summer on Dipsaceae or Valerianaceae. If the winter is mild, the colonies can overwinter parthenogenetically.
Macrosiphum rosae can transmit viral diseases to strawberry plants.
It is harmful to rose bushes and considered to be an important pest.
