Lima Beans use extrafloral nectar (EFN) secretion when exposed to volatiles from other plants infested by herbivore species. Producing EFN can be an indirect defense since it supplies enemies of herbivores with an alternative food source. The predator of lima bean, spider mites, also have their own predators, the carnivorous mite "Phytoseiulus persimilis". These predatory mites use EFN as an alternative food source and thus the production of this by the lima bean can attract "P. persimilis" and thus deter their herbivore hosts.
