Plants actively respond to damage with the induction of
defences. One of these defences involves emitting vola-
tiles that attract the enemies of the enemies of the
plant. Whether downwind neighbouring plants `eaves-
drop' on these cues and respond with the induction of
their defences too has been debated intensively. Evi-
dence in support of this hypothesis has been accumu-
lating recently, provoking exciting mechanistic and
ecological questions that need to be addressed.
