The brown planthopper has evolved a highly adaptive oviposition strategy by exploiting caterpillar-induced plant volatiles that provide safe havens for its offspring.

A chewing herbivore induced WRKY transcription factor induces jasmonate-dependent defences and supresses gibbererellin-dependent growth, the latter of which renders rice plants more susceptible to secondary infestation by a piercing-sucking herbivore.

The synthesis capability of some amino acids is lost during the insect evolution, and hymenopteran parasitoids can make up for these deficiencies by altering free amino acid concentrations in host.

A common rice pest can avoid its natural parasite by settling on plants that smell like they have been damaged by a species of caterpillar.

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.
