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
