The bird cherry-oat aphid, Rhopalosiphum padi is a major vector of the yellow dwarf viruses (YDVs) that infect cereals. R. padi has a complex life history. Many populations in temperate regions that have cold winters reproduce combining sexual and asexual phases (holocycly).   Bird cherry oat aphid (Rhopalosiphum padi L.) is a serious pest of wheat (Triticum aestivum L.) crop and causes significant production losses to the wheat crop in Pakistan. So far eight genes from the conventional wheat cultivars that are resistant to the attack of R. padi have been incorporated in the commercial wheat cultivars to help manage.

Bird cherry-oat aphid, Rhopalosiphum padi (L.), a polyphagous species with a nearly worldwide distribution, is an important pest of wheat as well as the main vector of barley yellow dwarf virus. We evaluated the resistance categories of eight wheat lines including antibiosis, antixenosis, and tolerance against R. padi under laboratory conditions. The wheat lines tested were ERWYT 88 Cited by: The bird cherry-oat aphid, Rhopalosiphum padi (L.) (Homoptera: Aphididae) is considered to be one of the most destructive pests of cereal crops in different parts of the world (Taheri et al., ; Descamps and Chopa, ). For instance, the estimated damage to cereal crops caused by R. padi in some parts of Europe can result in yield.

The aim of the study was to determine the effects of such flavonoids as: apigenin, luteolin, quercetin, mirycetin, (+)-catechin and (-)-epicatechin on the behavior of wingless females and larvae of bird cherry-oat aphid (Rhopalosiphum padi L.) during the colonization of winter wheat seedlings. All the tested compounds showed deterrence activity against thebird cherry-oat aphid .   Abstract. The bird cherry-oat aphid (Rhopalosiphum padi L.) is a global pest of wheat and vectors some of the most damaging strains of barley yellow dwarf virus (BYDV).In years of heavy R. padi infestation, R. padi and BYDV together reduce wheat yields by 30–40% in Kansas and other states of the U.S. Great Plains wheat production area. Cultivation of wheat cultivars resistant to R. padi Cited by: 2.

Summary. 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 Cited by: Ecology of the bird cherry-oat aphid, Rhopalosiphum padi (L.)

Visual Cues and Host-Plant Preference of the Bird Cherry-Oat Aphid, Rhopalosiphum padi (Hemiptera: Aphididae) Alate aphids respond to short (UV) and long (green-yellow) wavelength stimuli during host-plant searching behaviour. Although many aphids are attracted to yellow, the bird cherry-oat aphid, Rhopalosiphum padi, is attracted to green.

Methyl salicylate, a volatile component ofPrunus padus, the winter host ofRhopalosiphum padi, was found to reduce colonization of the summer host by this aphid.
