Although D. noxia feeds on leaves and flowers/seedheads of grasses, it appears to inject a polypeptide toxin that affects the entire plant (Hewitt et al., ). The Russian wheat aphid, Diuraphis noxia Kurdjumov, is one of the most important pests of small grains throughout the temperate regions of. The genome of Diuraphis noxia, a global aphid pest of small grains. Nicholson SJ(1)(2), Nickerson ML(3), Dean M(4), Song Y(5), Hoyt PR(6).

As a result, these aphids are now found on every continent except Australia and Antarctica.

Russian wheat aphid (Diuraphis noxia)

A multi-genome analysis approach enables tracking of the invasion of a single Russian wheat aphid Diuraphis noxia clone throughout the New World. Purple, as opposed to white, diurapyis appear more frequently when the plant has been exposed to low temperatures. Journal of Economic Entomology, 85 6: Aphid feeding on susceptible genotypes causes chlorosis and longitudinal streaking of leaves, and emerging leaves remain tightly rolled, which traps spikes and prevents their normal development Mornhinweg, Open in a separate window.
