Researchers at Oregon State University have built a device that communicates with winery pests using vibrations. The treehopper spreads devastating red blotch disease through vineyards in the Pacific Northwest, but it appears the insects can’t resist the vibrational calls that are reproduced by the “Pied Piper” robot. The scientists thinks the Pied Piper will be able to reduce the need for chemical pesticides and give organic growers in the Pacific Northwest new options for pest control.
