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).

New genera and two new species of Aphididae. The locust genome provides insight into swarm formation and long-distance flight. Effect of initial colony size on the per capita growth rate and alate production of the Russian wheat aphid Homoptera: It is particularly injurious to late-sown barley in continental climates. As viruses interact with specific epitopes of proteins involved in trans-membrane transport, it is likely that protein sequence differences between D.

Differential reactions of Russian wheat aphid to various small-grain host plants. In the Crimea, D.

Diuraphsi addition to D. Diuraphis noxia Kurdjumov Common name: Transmission of Moroccan isolates of barley yellow dwarf virus by the Russian wheat aphid Diuraphis noxia and other aphid species. Furthermore, Kindler et al. Journal of Economic Entomology, 88 5: Fire and grazing are important in the long-term maintenance of grasslands.


Architecture and evolution of a minute plant genome. Sign In Forgot password? In these diuraaphis the aphids look for the parts of the plant that are nutritional tissues and begin eating. Revue d’Entomologie russe, The aphid further increases the nutritional drainage of the host plant through eliciting an increase in essential amino acid in the phloem sap by triggering a breakdown of proteins in the host plant.

Hodgson and Karren, ; Merchant, The reduced repetitive element percentage in the D. In a recent study, 23 lines resistant to all biotypes, included 10 unadapted germplasm accessions and 13 improved germplasm lines, providing useful germplasm for developing new barley cultivars with resistance to multiple D.

There have been conflicting reports on the effect of D. These include planting date, planting density, furrow orientation, irrigation, fertilization, grazing, manipulation of crop residue, and alternative host plants.

TTAGG telomeric repeats in chromosomes of some insects and other arthropods. Bulletin of Entomological Research, 82 2: Comparison of OR dkuraphis across insect species is complicated by the fact they include receptors to detect sexual pheromones that are essential to reproduction. Molecular data support a rapid radiation of aphid in the Cretaceous and multiple origins of host alteration.

We sequenced and de novo assembled the genome of D. Resistance to the Russian wheat aphid Homoptera: The eyes and distal third of the antennae are dark; the head and thorax diuaphis winged adults are also dark. Sugar transporters Aphids diurapjis a sugar-rich diet with a high osmotic potential, requiring only proteins such as uniporters that allow movement of phloem sugars with the membrane concentration gradient and into the hemolymph [ 10 ].

The genome of Diuraphis noxia, a global aphid pest of small grains.

Key to this feeding process is the injection of saliva which modulates plant defenses [ 34 ]. Will T, van Bel AJ. Merrill and Holtzer, ; Merrill, et al. Natural enemy impact on the abundance of Diuraphis noxia Homoptera: Resistance genes in wheat appear to function in a biotype-specific manner with single genes providing resistance to one or more biotypes Puterka et al.
