When it comes to the sex lives of insects, entomologists sure know how to kill the mood. To keep pests from making love—and little bugs—they have developed all sorts of tricks, like spraying plumes of pheromones that lead love-struck males astray. Now, scientists have developed a new way to disrupt mating: shaking the insects’ perches to disrupt the vibrations that would-be partners normally use to find each other.

“This is a great new approach,” says Christoph Hoffmann, a biologist at the Institute for Plant Protection in Fruit Crops and Viticulture in Siebeldingen, Germany. These good—or bad—vibrations not only stop reproduction, but they may prevent a species of leafhopper from spreading a deadly disease through Europe’s vineyards.
