Plants respond to leaf vibrations caused by insect herbivore chewing

It appears that the vibrations caused by insect feeding can elicit chemical defenses in plants. Arabidopsis thaliana  pre-exposed to vibrations caused by caterpillar feeding had higher levels of glucosinolate and anthocyanin defenses when subsequently predated by Pieris rapae caterpillars, than untreated plants. The plants also showed discrimination between the vibrations caused by chewing and those caused by wind or insect song. This plants would appear to respond to herbivore-generated vibrations in a selective and ecologically meaningful way. The authors suggest that vibration may represent a new long distance signaling mechanism in plant–insect interactions that contributes to systemic induction of chemical defenses. Read more at
