The flowers color of R. gallica may arrange for attracted the rose aphid adults, as follow: yellow, red, blue, pink and white, respectively. Statistical analysis showed that highly significant differences between the five flowers color (varieties) of R. gallica on the attraction of adults of the rose aphid, M. rosae.

It can be arranging the flowers color of R. gallica for attract of the rose aphid (nymphs) as follows: yellow, red, blue, pink and white.
