vector for plant viruses

A vector for plant viruses is an organism that transmits the virus from one plant to another, helping the virus spread. Common vectors include insects like aphids, whiteflies, and thrips, which feed on plants and accidentally carry the virus on their bodies or in their saliva. When they move to a new plant, they can infect it with the virus. Some vectors are also tools like pruning equipment or contaminated tools that transfer viruses between plants. Understanding vectors is essential for managing and preventing the spread of plant viruses in agriculture and horticulture.
