The saliva of this aphid is toxic to the plant and causes whitish striping on cereal leaves.

The result of being a host of an aphid are damages through nutrient drainage which develops into symptoms such as chlorosis, necrosis, wilting, stunting and other growth impairment.

Aphid feeding in wheat results in qualitative and quantitative losses in flour yield.

[7] As D. noxia became an invasive species in North America, it is notable that they possess enough endurance to cold temperatures to survive through winter.

Host control consists of raising crops that possess genes that may contribute to aphid resistance.

[10][11] As these genes are marked for selective breeding, it may serve to manage the population of aphids.

[10] Hopper et al.'s research into biological control is based on the non-pest status of D. noxia in Eurasia, its area of origin.

Based on the selection of natural enemies of D. noxia in Eurasia, the paper performed a survey of host specificity of different species of parasite from the genus Aphelinus.

Due to this host specificity, the paper suggests that biological control of D. noxia may be viable through A. hordei introduction into the west.

It may serve as a method to deal with the population of aphids that have overcome wheat's genetic resistance.
