Russian wheat aphid can be found at any time in the wheat crop. Winged adults migrate into wheat fields from the south. It is also common for resident populations that over-summer on wild grass species to give rise to small infestations in wheat that may be unnoticed in the fall.

Labels related to the pest - Aphid, Russian Wheat. Russian Wheat Aphid Diuraphis noxia is a root nourishing insect, and controls the production of a monoterpene volatile (1, 8-cineole), which is toxic and repulsive to some insects (Ro et al., ).

Russian wheat aphid resistant wheat,” says Puterka. His ultimate aim is the real game changer: development of wheat resistant to all biotypes. Native to the Russian steppes and Central Asia, but spread virtually worldwide, the 1/inch-long Russian wheat aphid popped up in Mexico in and then during in the western United States and.

Progress 09/15/03 to 09/14/06 Outputs This project was heavily influenced by reports in of a new biotype (biotype 2) of Russian Wheat Aphid (RWA) that was able to overcome the resistance in all Colorado RWA-resistant wheat varieties.

Several additional RWA biotypes were later identified. This situation mandated an accelerated program to locate new RWA resistance sources, incorporate the. Aphelinus asychis is a parasitoid wasp native to Eurasia that was introduced to North America to control the Russian wheat aphid.

Recent work shows that the species as currently described does not form a monophyletic group and its taxonomy and phylogenetic relationship should be : Aphelinidae. Russian wheat aphid, Diuraphis noxia (Mordvilko) (Insect answers) [Keith S Pike] on *FREE* shipping on qualifying : Keith S Pike.

After wheat harvest, the aphid moved to Hordeum murinum L. ssp. glaucum (Steudel) Tzvelev, Phalaris spp. and volunteer wheat and barley plants.

The D. noxia population on late sown wheat was three times higher than that on early sown plants. Conversely, the numbers of parasitised aphids and predator mites were higher in early sown by: 9.

Several resistant lines of wheat, Triticum aestivum (L.) (Poaceae), have been developed to control populations of the Russian wheat aphid, Diuraphis noxia (Mordvilko) (Hemiptera: Aphididae).

We examined the potential effects of D. noxia resistant lines on another aphid, the bird cherry-oat aphid (Rhopalosiphum padi (L.) (Hemiptera: Aphididae)), which commonly co-occurs with D. by: The Russian wheat aphid, Diuraphis noxia (Mordvilko), is a newly established pest of small grains in western North America (Stoetzel ).

This aphid also feeds on several native and introduced grasses, including grasses that are widely planted for forage improvement or erosion prevention in rangelands (Kindler and SpringerKindler et al.

Goals / Objectives Develop and integrate sustainable Russian wheat aphid and greenbug management methods in areawide demonstration projects; form long-term partnerships among Federal, State, and private sector; transfer to growers economical and ecologically sound technologies to manage these pests on grain crops.

Grain growers in southern and northern cropping regions are advised to keep an eye on their crops over the coming weeks as warmer spring conditions may promote flights of Russian wheat aphid (RWA). RWA numbers have been minimal so far this season, due largely to low survival rates over the hot and dry summer.

However, wheat yield has been declining over the past years. The purpose of this study was to investigate farmers’ cultivation practices, knowledge and management of Russian wheat aphid as possible factors for the low yields of wheat, and the capacity of extension staff in assisting the farmers in wheat production in Mokhotlong and Thaba.

In Ethiopia, more than 38 species of insect pests have been reported to affect barley. Of these, eight are aphid species; the most important is the Russian Wheat Aphid (RWA) (Diuraphis.

Abstract This booklet is profusely illustrated in colour and provides a review of the recognition, distribution, biology, natural enemies, biological control, host plants, pest resistance (in wheat and barley), injuriousness and control of Diuraphis noxia in north-western USA (especially Washington, Oregon and Idaho), a fairly recently introduced and economically important pest there.

Two of the species commonly known as Russian Wheat Aphid (Diuraphis noxia)and Bird Cherry-Oat Aphid (Rhopalosiphum padi) are considered notorious for their direct and indirect losses.

Diuraphis noxia (Kurdjumov) (Homoptera: Aphididae) has been the most important pest of wheat, Triticum aestivum, in the summer rainfall production areas of South Africa since its first report as pest in (Walters ).This aphid is endemic to central Asia, southern Russia, countries bordering the Mediterranean Sea, Iran and Afghanistan (Durr ; Hewitt et al.

; Dolatii et al. Cited by: Volunteer wheat is host to the wheat curl mite (which is the vector of a complex of three wheat diseases), the Russian wheat aphid, and several other pest problems. Volunteer wheat should be controlled throughout the fallow period and must be completely eliminated at least a day period between wheat harvest and wheat seeding.

Specimens in the collection allowed scientists to quickly determine that the biotype was not a new introduction to the country.

During early stages of infestation by Russian wheat aphids (Diuraphis noxia [Mordvilko]; RWAs), barley (Hordeum vulgare L.) leaf cells collapsed and showed autofluorescence in the mesophyll and bundle sheath adjacent to the RWA stylet sheath. The response was visually similar to the hypersensitive cell death response, typical of resistance to microbial by: Russian wheat aphid (RWA), Diuraphis noxia (Kurdjumov), is a major pest of wheat and barley, especially in warm climates, causing massive grain losses in severe infestation.

Losses of up to 90% of the crop have been reported in severe infestations in Kenya, the USA, South Africa and Iran [1,2,3].Traditionally, long-term sustainable management of RWA relies on host plant resistance (HPR).Cited by: 2.
