Pierce's disease is spread by which vector?

Explanation:
Pierce's disease is transmitted by xylem-feeding insects known as sharpshooters. These leafhoppers feed on the plant’s xylem sap, acquiring the bacterium Xylella fastidiosa from an infected grapevine and then inoculating healthy vines when they feed again. Because the pathogen travels within the xylem, only vectors that feed on xylem can spread it. Wind-blown particles cannot move living bacteria between plants, phylloxera is a root-attacking pest not known to transmit this disease, and sooty mold is a fungus that grows on honeydew rather than spreading the pathogen.
