“…Most aphids feed on the phloem and are considered to be agriculturally important pests because they serve as vectors of approximately 275 plant viruses, leading to significant crop losses, especially in temperate regions [ 22 , 23 ]. Aphids use specialized mouthparts, stylets, to promote plant susceptibility by injecting saliva containing proteins and other compounds [ 24 , 25 , 26 , 27 , 28 , 29 , 30 ]. Aphid feeding on mycorrhizal plants results in above-ground changes in volatile compounds and foliar chemistry as well as below-ground changes in AM fungal root colonization and composition, plant carbon allocation to the AM fungus, and plant–plant communication via mycorrhizal networks [ 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ].…”
