Tripartite interactions of Barley yellow dwarf virus, Sitobion avenae and wheat varieties.
The tripartite interactions in a pathosystem involving wheat (Triticum aestivum L.), the Barley yellow dwarf virus (BYDV), and the BYDV vector aphid Sitobion avenae were studied under field conditions to determine the impact of these interactions on aphid populations, virus pathology and grain yield.Wheat varietal resistance to BYDV and aphids vari
