Abscisic acid is a sequiterpene phytohormone that is induced by drought and promotes stomatal closure and seed dormancy. Other sesquiterpenes take part in tritrophic plant-herbivore-parasite interactions (reviewed by Dudareva et al., 2006). In maize infested with lepidopteran larvae, the sesquiterpenes ( )-P-famesene and the ( )-a-bergamotene (Fig. 30) attract the parasitic wasp Cotesia marginiventris (Schnee et al., 2006). Maize roots release ( )-P-caryophyllene (Fig. 30) upon attack of larvae of the beetle Diabrotica virgifera to attract the parasitic nematode Heterorhabditis megidis (Rasmann et al., 2005).
