Sharpshooter Insects’ Vibrations Spell Trouble in Vineyards

Season 7 Episode 9 | 5m 16s

Sharpshooter insects are beautiful, but they transmit a devastating disease that kills grapevines. When it's time to mate, they shake their abdomens to make strange calls that – when amplified in a lab – sound like a clucking chicken, a howling monkey or a motorcycle revving up. Now scientists have found a way to use their songs against them.
