Vibrational Mating Calls of the Blue-Green Sharpshooter

The blue-green sharpshooter (BGSS) is a xylem-feeding leafhopper that vectors the bacterium Xylella fastidiosa, the causative agent of Pierce’s disease in grapes. This sharpshooter is native to the western United States where it is found commonly throughout much of California. Although this pest has been problematic for over 100 years, little basic research has been conducted on it.
