Aphids are garden bugs that suck sap from plants. If they suck the sap of an infected plant, they have the virus on them and then when they move to another plant and penetrate it to suck the sap, they can infect the second plant with the viruses on their faces and in their mouths.
Piercing, sucking mouthparts and saliva allow an aphid to transmit viruses.
Specifically, aphids are soft-bodied insect pests that feed on a plant's phloem and xylem saps. They manage to piece a plant's foliage by way of razor-sharp mouthparts known as stylets, which leave an opening around which a sheath is left. Viruses may be transmitted by the saliva which an aphid releases and by the vectorability of the stylets and sheaths.
Aphids attack a number of crops and are vectors of many viruses attacking sweetpotato and other crops.
Yes they do
Plants have stronger cells walls. And viruses do spread to plants.
New viruses are released after the lytic cycle. ~Gradpoint/Novanet
Some computer viruses.
Adult aphids of breeding age have wings and fly to a new food source: tender vegetation. Some ants also "tend" aphids, and will actually bring aphids to plants in order to harvest the honeydew produced by feeding aphids.
because the can kill plants by sucking the sap and vector plant viruses and diseases
Macro viruses
No, computer viruses are spread via removable media, and the internet
Not normally as they are biting and chewing insects. Diseases are normally spread by sap sucking insects like Aphids
No
