Russian wheat aphid

Russian wheat aphid (Diuraphis noxia) is found in all major cereal production regions around the world however never in Australia before now.
It is a major pest of cereal crops that injects toxins into the plant during feeding which retards growth and with heavy infestations, kills the plant.
The aphid is spread easily by the wind and on live plant material.
Affected plants will show whitish, yellow and red leaf markings and rolling leaves.
Russian wheat aphid is approximately 2mm long, pale yellowish green with a fine waxy coating. The body is elongated compared with other cereal aphid species.
