Plant Signaling
Olive groves, lavender fields, and rosemary hedges across southern Europe are being wiped out by a bacterium this tiny insect carries — and it turns out, playing the sound of ants through the stems may be enough to keep it from feeding.
Spittlebugs are small insects that spread a deadly plant disease by feeding on plant sap. Researchers found that when they played recordings of vibrations made by ants or spiders through the plant stem, the spittlebugs got spooked — they froze, moved away, fed less, and took much longer to reach the parts of the plant they were after. Even recordings of other spittlebugs arguing over territory had a similar effect. The big idea: you might be able to protect plants just by making them 'vibrate' like a dangerous place to eat.
Key Findings
Ant vibrations reduced the number of spittlebugs that reached and fed from xylem (sap-carrying) vessels by 52%
The spittlebug male hierarchy call caused the highest rate of plant abandonment at 48%, also delaying sustained feeding
All vibrational signals—whether from predators or abiotic sources—reduced spittlebug presence on preferred plant tips, suggesting a broad, non-specific startle response
chevron_right Technical Summary
Scientists discovered that playing recordings of ant and spider vibrations through plants dramatically disrupts how spittlebugs—a major disease-spreading insect—feed on them, cutting their ability to reach plant vessels by over half. This opens the door to using 'vibrational pest control' to slow the spread of a devastating plant disease.
Abstract Preview
Insects are continuously exposed to a vibroscape, namely the array of substrate-borne vibrations produced by conspecifics, heterospecifics, or abiotic sources, which influences their interaction wi...
