 Distinction is based on different symptoms in one or two chosen hosts and also on, for example, differential physico-chemical properties.The vectors are insects of the order "Hemiptera", family "Aphididae"; green peach aphids ("Myzus persicae") and at least 14 other species are known to play that role.AMV can also be transmitted by seed, pollen, through mechanical inoculation of plant sap and by the parasitic plant dodder ("Cuscuta").
