Vibrational directionality in the southern green stink bug, Nezara viridula (L.), is mediated by female song

It has been possible to produce the first direct evidence that vibrational directionality is used during mating behaviour in insects and that this phenomenon is sex specific. Research in this area tested the hypothesis that male southern green stink bugs, Nezara viridula (L.), use substrate-borne songs to locate females. The fact that the directionality response was shown only in males corresponds with observations on a plant where females were not seen to approach the singing male. There is still uncertainty about the precise mechanism underlying vibrational directionality in the southern green stink bug, but spatial differences in timing and amplitude may be used.
