“…Other researchers found significant differences in resistance against R. padi among wheat varieties Niraz et al, 1985;Havlickov~, 1988;Heyer & Wetzel, 1988;Radchenko, 1989;Krivchenko & Radchenko, 1990). Roberts & Foster (1983) found that the pubescent-leaved wheat varieties attracted a significantly lower number of R. padi, than the glabrous-leaved ones.…”

“…The 'Downy' with its leaf surface pubescence (Roberts et al, 1981) was used as resistant check cultivar, as Roberts & Foster (1983) found that a high trichome density on the surface of the flag leaf affected adversely not only the feeding damage of (9. melanopus, but also the number of R. padi. The infestation severity of R. padi was determined as a percentage of surface covered by aphids related to the total surface of the plant.…”

In Hungary the bird cherry-oat aphid (Rhopalosiphum padi L.) is the most frequent aphid species in winter wheat (Triticum aestivum L.). Estimations of infestation by R. padi as well as measurements of grain yield and thousand-kernel mass were carried out in 26 winter wheat genotypes in conditions of naturally infested and not infested (protected) control plots. The experiment was performed in isolated conditions in two field cages covered by nets. The aphids overwintered on wheat and got into cage, extremely quickly multiplied, therefore there was no need to apply any artificial aphid infestation. Highly significant differences were demonstrated among genotypes in infestation severity of R. padi as well as in losses of grain yield and thousand-kernel mass. The most resistant variety 'GK Zombor' had 25% infestation, and the most susceptible one 'GK Lili' had 79.2%. The reduction of grain yield of the most tolerant genotypes ('GK Kor~iny', 'Downy', 'Mv 4', 'Jubilejnaja 50', 'Mv 8', 'GK Kincs6' and 'GK Zombor') was 26-33 %, and that of thousand-kernel mass was 23-30%. The most sensitive genotypes ('GK Lili', 'GK Orzse', 'GK Kopp~iny' and 'Mv 13') suffered 58-63% losses in yield, and 40-50% in thousand-kernel mass. A close correlation was found between infestation of R. padi in different wheat genotypes and losses of grain yield (r = 0.7572, P < 0.001). Also there were tolerance differences among genotypes even within the same level of infestation. The reductions of thousand-kernel mass correlated very closely with the reductions of grain yield (r = 0.9212, P < 0.001), that makes screening possible by reductions of thousand-kernel mass. These results have found application in breeding. The leaf pubescence of the varieties studied did not generally influence the infestation by R. padi.

“…The low quality of plants can perform as a defence mechanism against herbivorous pests and cause a decline in their fecundity and an increase in developmental time (Legrand & Barbosa 2000). Various studies have been conducted to detect at least a relatively resistant cultivar for the development of control techniques of aphids and to decrease insecticide applications (Roberts & Foster 1983;Papp & Mesterházy 1993;Ozder 2002;Razmjou et al 2006Razmjou et al , 2009. For accurate decision-making in IPM, it is also necessary to determine the pest population growth parameters on different hosts and cultivars.…”

Taheri S., Razmjou J., Rastegari N. (2010): Fecundity and development rate of the bird cherry-oat aphid, Rhopalosiphum padi (L) (Hom.: Aphididae) on six wheat cultivars. Plant Protect Sci., 46: 72-78.Rhopalosiphum padi is a polyphagous species with a nearly worldwide distribution. Biological parameters of this aphid on six commonly grown wheat cultivars in the Fars province including Chamran, Darab2, Shiraz, Ghods, Marvdasht and Niknezhad were investigated at the two-leaf stage of wheat. The experiments were carried out at 24 ± 5°C, 65 ± 5% R.H. and a photoperiod of 14:10 h (L:D) in a greenhouse. The number of nymphs per female of R. padi was 62.05, 55.84, 49.89, 47.63, 42.76 and 40.65 (nymphs/female) on Niknezhad, Shiraz, Ghods, Marvdasht, Chamran, and Darab2, respectively. Also, the highest and the lowest r m values of this aphid were obtained on Niknezhad (0.381 per day) and Darab2 (0.328 per day), respectively. In addition, other population growth indices were estimated. In general, a high level of antibiosis in Darab2 compared with the other tested cultivars may decrease the population density of R. padi on wheat and also cause a suppression of cereal viruses (e.g. BYDV) and reduce the pesticide application to wheat fields of Iran.

“…However, they were separated by a distance of 14.6 cM, and classification of RILs based on pubescence data showed no effect on antibiosis to R. padi. Some studies (Roberts and Foster 1983;Webster et al 1994), but not all (Webster 1990;Papp and Mesterhazy 1993), have suggested that one possible cause for aphid resistance in wheat is the presence of trichomes in leaves. However, in our study neither R. padi nor S. graminum resistance was related to such a plant trait.…”
