“…Management of D. noxia has largely relied on resistant wheat cultivars (Smith 1999, Webster andKenkel 1999). Wheat cultivars containing D. noxia-resistant genes, which have different levels of antibiosis, tolerance, or both (Randolph et al 2005a), have been shown to harbor fewer D. noxia populations and have higher yields compared with their susceptible wheat counterparts (Randolph et al 2003(Randolph et al , 2005b. Resistant plants also have demonstrated compatibility with other management tactics by exhibiting an absence of leaf rolling when infested with D. noxia, which would expose the aphids to chemical and biological management (Hawley et al 2003).…”

We examined the physiological and biochemical responses of resistant ('Halt' and 'Prairie Red') and susceptible ('TAM 107') wheat, Triticum aestivum L., to injury by the Russian wheat aphid, Diuraphis noxia (Mordvilko). Photosynthetic capacity was evaluated by measuring assimilation/internal CO2 (A/Ci) curves, chlorophyll fluorescence, chlorophyll, and nonstructural carbohydrate content. Total protein and peroxidase specific activity also were determined. No significant differences were detected in chlorophyll concentration between aphid-infested and control TAM 107 plants. The aphid-infested resistant cultivars had similar or significantly higher chlorophyll concentrations compared with their respective control plants. Measurements over time showed that infested Halt plants had delays in photosynthetic senescence, Prairie Red plants had photosynthetic rate changes that were similar to control plants, and TAM 107 plants displayed accelerated photosynthetic senescence patterns. The photochemical and nonphotochemical quenching coefficients were significantly higher in infested Halt plants compared with their respective control plants on day 3. Infested TAM 107 plants had significantly higher photochemical quenching compared with control plants at all times evaluated, and they had significantly higher nonphotochemical quenching on day 3. Throughout the experiment, infested Prairie Red plants exhibited photochemical and nonphotochemical quenching coefficient values that were not significantly different from control plants. Total protein content was not significantly different between aphid-infested and control plants for all cultivars. Differences between physiological responses of infested susceptible and resistant cultivars, particularly temporal changes in photosynthetic activity, imply that resistant Halt and Prairie Red wheat tolerate some impacts of aphid injury on photosynthetic integrity.

“…Tolerance has been reported for Tugela-Dn2 (Wang et al 2004), Dn4 resistance in PI372129 (Meyer & Peairs 1989) and 'Halt' (Hawley et al 2003). Antibiosis was reported in CO 940626 carrying the Dn4 and Dn6 genes (Al-Ayedh 2000), 'Ankor', 'Stanton' (Randolph et al 2006) and 'Halt' (Hawley et al 2003, Randolph et al 2006, mainly expressed as lower aphid fecundity, while negative affects on developmental biology have been reported in other backgrounds (e.g., Tugela-Dn1, Tugela-Dn2 and Tugela-Dn5 ) (Wang et al 2004). The Dn7 gene confers antixenosis (Anderson et al 2003) as well as antibiosis (Peng & Lapitan, unpublished).…”

A lack of understanding the interaction between the Russian wheat aphid (RWA) and its host plant is a limitation in developing effective strategies for controlling the aphid. It is generally assumed that the interaction between aphid and plant is similar to that between plant and pathogen; that is, an elicitor from the insect is recognized by a protein from the host plant and a cascade of signal transduction events follows. However, evidence suggests that RWA feeding is eliciting both the SA-and JA/ethylene-dependent signaling pathways by mimicking aspects of both pathogen and herbivorous insect attacks. Results further suggest that phenotypic symptoms after RWA feeding are under regulation via two independent reactions, namely an immediate response (i.e., leaf rolling) and a downstream event (i.e., chlorosis). These defense responses enable a resistant host plant to defend itself and overcome the stress response, while their susceptible counterparts die. The processes involved in the onset of the defense response are discussed, and mechanisms enabling resistant plants to overcome the stress associated with the feeding process are presented as a working model for RWA-cereal host interaction. Knowledge of genes involved in wheat's defense responses against the RWA and an understanding of their functions may provide additional strategies for developing broad-spectrum resistance in plants.

“…A few previous studies have assessed the development of aphid populations in field trials on wheat germplasm previously evaluated under controlled conditions, e.g. Randolph et al (2003) for Diuraphis noxia (Mordvilko) and Migui and Lamb (2004) for S. avenae.…”

Field population development of bird cherry-oat aphid and greenbug (Hemiptera: Aphididae) on wheat-alien substitution and translocation lines

The aphids Rhopalosiphum padi L. and Schizaphis graminum (Rondani) are destructive pests of wheat (Triticum aestivum L.). In field trials in northwest Mexico, we examined the development of R. padi and S. graminum populations on six wheat genotypes that had previously been assessed for aphid resistance under controlled conditions. Five of these wheat genotypes carried different alien translocations in the genetic background of the spring wheat cultivar Pavon F76, which was used as the control. The trials were established in a randomized complete block design and repeated in three successive sowings. Aphids were sampled weekly from tillering stage until collapse of the aphid populations in the control. Number of aphiddays (i.e. the area under the curve of aphids per tiller) was calculated to compare population sizes. Genotypes 1AL.1RS e and (1D)1R pr significantly reduced R. padi populations across all sowing dates, by 32.8 and 24.1 %, respectively, compared with the control. Interaction between the wheat genotypes and sowing had a significant effect on the aphid-days of S. graminum. Genotype 7A.7S-L5 with Aegilops speltoides Tausch chromatin significantly reduced the S. graminum population by between 48.5 and 74.8 % in the three sowings compared with the control. These three wheat genotypes were also previously characterized as resistant in laboratory trials and can be considered promising resistance sources to R. padi and S. graminum in wheat breeding programs.
