Lima bean (Phaseolus lunatus) features two inducible indirect defences to protect itself
against herbivores. Besides the emission of plant volatiles, extrafloral nectar is secreted to
attract carnivorous arthropods to herbivore-damaged plants. The activation of both putative
defences efficiently protects Lima beans from leaf damage. In a field experiment in Mexico,
we studied whether extrafloral nectar alone can benefit the Lima bean under natural
conditions. An artificial blend mimicking natural nectar both qualitatively and quantitatively …
