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.

In contrast, the five largest pea aphid lineage-specific expansions were Kelch siuraphis additional genesa retrotransposon peptidase additional genestwo unclassified gene families 92 and 89 additional genesand a zinc finger protein 79 additional genes.

However, some workers e. Russian wheat aphids have short antennae and a piercing-sucking stylet on their head. Economic injury level for the Russian wheat aphid Homoptera: The rapid spread of D. The three largest in-paralog families contained 35 proteins each and the smallest separate groups held two proteins each. Host-Plant Resistance Resistance has been identified in barley and different wheat genotypes, including bread and non-bread wheat e.

Environmental Entomology, 23 5: Purple, as opposed to white, streaks appear more frequently when the plant has been exposed to low temperatures. Barley Aphid [Cuernavaca noxius Mordvilko ]. These wasps are often used as natural biocontrol methods to prevent infestations of Diuraphis noxia. These bacteria are housed within specialized bacteriocytes in the aphid gut lining and produce essential amino acids lacking in the host plant phloem [ 92 ].

It may be possible to improve the level of aphid control by combining plant resistance and biological control van Emden and Wratten, Biological Noxiia, 4 3: It is possible that natural enemies in that area limit the abundance of the aphids, therefore preventing them from becoming pests.
