Abstract Atmospheric carbon dioxide (CO 2 ) concentration has increased significantly and is projected to double by 2100. To increase current food production levels, understanding how pests diseases respond future climate driven increasing CO imperative. We investigated the effects of elevated (eCO on interactions among wheat (cv. Yitpi), Barley yellow dwarf virus an important pest vector, bird cherry-oat aphid ( Rhopalosiphum padi ), examining life history, feeding behavior plant physiology biochemistry. Our results showed for first time that infection can mediate eCO plants pathogen vectors. Changes in N influenced history was affected under . observed a reduction population size damage noninfected but no changes virus-infected irrespective treatment. expect potentially lower populations change or therefore subsequent spread. findings underscore complexity between plants, insects viruses with implications disease epidemiology crop production.
