Oral secretion products from chewing insects have been suggested as triggers that augment the release of plant volatiles.

Oral secretion products from chewing insects have been suggested as triggers that augment the release of plant volatiles. Beet armyworm caterpillars might trigger volatile emissions in corn plants through a fatty acid derivative (volicitin) in their oral secretions. Design an experiment to determine whether this chemical elicits a defense response from corn plants through release of plant volatiles.
