Russian wheat aphid

Summary

Russian wheat aphid (RWA) (Diuraphis noxia), is a newly arrived pest of wheat, barley and other cereal grains. Russian wheat aphid damages plants by injecting salivary toxins and can severely reduce yields if not controlled.

Russian wheat aphid is adapted to semi-arid dryland climates with an average annual rainfall less than 600 mm and therefore is expected to survive in Australian grain growing regions.

The Russian wheat aphid’s host range also includes several non-crop grasses.
