“…The D. noxia colony was established from aphids collected on spring wheat near Asotin, WA, in August 1988 and reinoculated with aphids collected near Moscow, ID, each year since that time. Insect colonies were maintained in environmental chambers as described by Quisenberry and Schotzko (1994).…”

“…Most of these aphids cause direct damage to the plants by feeding. In addition to the quantiÞcation of the impact of resistant lines on the target pest, understanding interactions between D. noxia-resistant wheat and other cereal aphids is important for the effective use of plant resistance as part of a management strategy (Quisenberry and Schotzko 1994). Wheat lines that display resistance to D. noxia may also affect other aphid species that damage the crop.…”

Field experiments were conducted in 1997 and 1998 to evaluate the impact of resistance to Russian wheat aphid, Diuraphis noxia (Mordvilko), on the cereal aphid complex in wheat. Two spring wheats were planted: the variety "Centennial" (Russian wheat aphid susceptible) and the advanced line IDO488 (Russian wheat aphid resistant). IDO488 incorporates the resistance found in PI 294994 into a Centennial background. Field plots were artificially infested with adult D. noxia and sampled weekly. The most abundant aphid species in 1997 were Metopolophium dirhodum (Walker), Sitobion avenae (F.), D. noxia, and Rhopalosiphum padi (L.). In 1998, the order of abundance was M. dirhodum, R. padi, S. avenae, and D. noxia. The resistant genotype had significantly fewer D. noxia than the susceptible one during both years. However, plant genotype had no significant effect on the other aphid species in either year. Both the initial density of D. noxia and plant growth stage, had a significant effect on D. noxia population development, but had no effect on the other aphid species. There was no interaction between D. noxia resistance and the population density of the other aphid species observed.

“…Improving our understanding of how D. noxia affects host physiology is important in identifying new targets for aphid-resistance in wheat. Russian wheat aphid resistance in wheat and barley (Hordeum vulgare L.) has been extensively investigated (Du Toit 1989, Webster et al 1991, Smith et al 1992, Miller et al 1994, Quisenberry and Schotzko 1994, Unger and Quisenberry 1997. The Þrst D. noxia-resistant commercial cultivar of hard red winter wheat, ÔHaltÕ, was released in 1996 (Quick et al 1996).…”

The impact of light and its role in Russian wheat aphid, Diuraphis noxia (Mordvilko), damage symptom formation, and photosynthetic capacity in 'Arapahoe' wheat (Triticum aestivum L.) were examined. After 72 h under continuous dark or continuous light regimes, the number of aphids (nymphs), leaf rolling and chlorosis ratings, fresh leaf weight, and chlorophyll contents were recorded. Photosynthetic rates, chlorophyll a, kinetics and chlorophyll extractions also were determined. Aphid infestation caused significant reductions in plant height, fresh weight, gas exchange, and chlorophyll fluorescence only under continuous light. Under the 72 h continuous dark regime, aphid infestation did not cause either damage symptom formation or reduction in plant growth or metabolism (photosynthesis). Furthermore, significantly more D. noxia nymphs were produced under continuous light condition than continuous dark. Our results demonstrate that the development of D. noxia feeding damage symptoms (i.e., leaf rolling and chlorotic streaks) on susceptible wheat seedlings is a light-activated process, even though the elicitor of the plant damage symptoms is aphid feeding.

“…Using host plant resistance instead could be economical, efective throughout the growing season, environmentally safe and it will require no elaborate technology transfer to farmers. Natural enemies and host plant resistance are considered as more desirable alternatives to insecticides because of their low cost and environmentally friendly mitigation strategy [12,51] for efective management of cereal aphids in wheat.…”

Cereal aphids cause direct damage to rainfed wheat through sucking of plants sap and cause losses of up to 90%, particularly in dry years in Kenya. The Russian wheat aphid (RWA) is the most destructive and may account for up to 50% yield loss or more depending on the severity and length of infestation. Current control strategies mainly rely on the use of insecticides to control cereal aphids' infestations. Chemicals improve yields in the short term, but adversely afect the environment, hence the need for development of efective IPM strategies. Early planted crops escape heavy aphid atacks and give good yields. A combination of seed rate of 100 kg and 100 kg N/ha provided the best cultural management of RWA. Ladybird beetles Adonia variegata, lacewings (Chrysoppa spp.) and parasitic wasp Aphidius sp. were the most important natural enemies. Control of cereal aphids can be achieved with systemic insecticides applied as seed dressings or foliar applied insecticides. Four lines of wheat were found to show RWA resistance and crosses with Kenyan wheat made and populations are being evaluated for resistance to cereal aphids.
