Resistance in Triticum aestivum, Triticum monococcum and Triticum turgidum to Rhopalosiphum padi

The European Zoological Journal
The bird cherry-oat aphid Rhopalosiphum padi (L.) (Hemiptera: Aphididae) is a cosmopolitan species that attacks all the major cereals, causing the yield loss directly by removing nutrients and indirectly by vectoring plant virus diseases. The study aimed

Genetic structure at national and regional scale in a long-distance dispersing pest organism, the bird cherry–oat aphid Rhopalosiphum padi

, 2019
Genetic diversity is determinant for pest species’ success and vector competence. Understanding the ecological and evolutionary processes that determine the genetic diversity is fundamental to help identify the spatial scale at which pest populations are

Population Ecology of Aphids and Their Associated Predators on Wheat Crops in Najaf, Iraq [PDF]

Journal of Plant Protection and Pathology
This study was conducted to assess the population density of certain aphid species and their key insect predators on wheat crops in Najaf, Iraq. The study employed two sampling methods: direct counting and sweep net collection. The findings indicate that

Difficulties in location and acceptance of phloem sap combined with reduced concentration of phloem amino acids explain lowered performance of the aphid Rhopalosiphum padi on nitrogen deficient barley (Hordeum vulgare ) seedlings

, 2000
Effects of nitrogen deficiency in hydroponically grown barley seedlings (Hordeum vulgare L.) on the development and reproduction of the aphid Rhopalosiphum padi (L.) (Hemiptera: Aphididae) were investigated.

Volatile-mediated interactions between cereal aphids and Fusarium graminearum shape wheat susceptibility to pest and pathogen induced biotic stress

Plant Stress
Cereal aphids (Sitobion avenae F., Rhopalosiphum padi L.) and Fusarium graminearum, the causal agent of Fusarium head blight (FHB), are major biotic threats to wheat that interact via their shared host. Co-localised S.

Resistance of Triticum species to cereal aphids

Czech Journal of Genetics and Plant Breeding, 2011
The resistance of Triticum ssp. to English grain aphid (Sitobion avenae F.) and bird cherry-oat aphid (Rhopalosiphum padi L.) has been studied in different regions of Russia and the former Soviet Union. The dependence of resistance to aphids on the wheat

A mutation in amino acid permease AAP6 reduces the amino acid content of the Arabidopsis sieve elements but leaves aphid herbivores unaffected [PDF]

, 2010
The aim of this study was to investigate the role of the amino acid permease gene AAP6 in regulating phloem amino acid composition and then to determine the effects of this altered diet on aphid performance.
