Tri-partite complexity: odour from a psyllid's mutualist ant increased predation by a predatory mite on the psyllid.

To our knowledge, this is the first report indicating increased consumption rates by natural enemies exposed to odour from a mutualist of pest (ant). This finding may provide new insights into understanding tri-partite interaction involving a pest, its predator, and a mutulist of the pest. © 2018 Society of Chemical Industry.
