Morphology : The body of apterous females is green-brown; the legs and the long siphunculi are brown-black and the long cauda is pale. The alate females are similar to the apterae, except that the head and thorax are dark. The body of both female forms is mm long and their antennae are longer than the bodies. Life cycle : In the Middle East this aphid reproduces throughout the year on roses by viviparous parthenogenesis. During summer it also occurs on other Rosaceae, such as apple and pear.

At In cooler regions males and females occur in winter, mate, and the females lay eggs on rose canes. Economic importance : This pest stunts the growth of roses, infesting their leaves, buds, young shoots and flowers, greatly reducing their market value. Much damage can occur when large colonies develop on the buds and the growing points. The aphid produces very little honeydew , which is colonized by sootymold fungi, that further reduce market value.

Abroad the rose aphid vectors several virus diseases but not of roses , including the debilitating PVY. Chemical control : This aphid is a minor pest, which may be controlled with organophosphates. Biological control : The rose aphid is attacked by the specific endoparasitoid Praon rosaecola Stary, Aphidiidae , which greatly reduces pest numbers. Satisfactory control with the coccinellid Harmonia axyridis Pallas was reported from France.
