A 2-year field study has demonstrated that volatile compounds produced by plants when they are attacked by herbivores act as defenses by attracting predators to the herbivores and increasing the reproduction of the plants.
Both the frequency of sesquiterpene-emitting individuals and the defense capacity of individual plants determine the consequences of sesquiterpene volatile emission for individuals and their neighbors in populations of the wild tobacco Nicotiana attenuata.

Real-time volatile emission kinetics reveal stress volatiles emitted from herbivore-damaged plants can sequentially prime and induce defense responses in undamaged plants following distinct temporal patterns.

It is hypothesized that volatile organic compounds emitted by plants after stress induction may be sensed by neighboring eavesdropping plants using odorant-binding proteins.
A moth can detect plant volatiles using an odorant receptor expressing in its ovipositor, and this odorant receptor has a much higher expression level in the ovipositor than antennae.
The ability of Manduca moths to recognize changes in the profile of volatile compounds released by plants being attacked by Manduca caterpillars allows them to lay their eggs on plants that are less likely to be attacked by insects and other predators, and to avoid competing against other caterpillars of the same species for resources.
The brown planthopper has evolved a highly adaptive oviposition strategy by exploiting caterpillar-induced plant volatiles that provide safe havens for its offspring.
Instead of repelling, Desmodium, a hallmark of pest suppressive sustainable intercropping, acts as a mechanical and developmental barrier to larvae, thereby truncating population development.
The natural volatile component DMNT protects plants from insect attacks by damaging peritropic matrix barriers in insect midguts, paving a promising way for the molecular breeding of plant protection.
