Pierce's Disease is spread by which vector?

Explanation:
Pierce's Disease is transmitted when a xylem-feeding insect picks up the bacterium Xylella fastidiosa from an infected vine and then inoculates a healthy one as it continues feeding. The glassy-winged sharpshooter is a highly efficient vector for this bacterium in vineyards, capable of moving between many plants and spreading the disease rapidly. Aphids, nematodes, and beetles do not serve as the primary vectors for this disease, so the insect responsible is the glassy-winged sharpshooter.
