The unusual chemistry sent Karl and her collaborators hunting for more rocks to test. This meant days-long backpacking trips into remote wilderness or submersible dives to underwater volcanoes.

Identifying more compounds that act as chemical signals is crucial, says Turlings. And the approach could be combined with other transgenic pest control methods such as using genetically modified crops that carry toxins.

Guy Poppy, a chemical ecologist from the University of Southampton, UK, agrees that the method should allow farmers to reduce crop damage without eradicating the entire population of pests in a field's ecosystem-allowing biodiversity to remain mostly unchanged.

future studies should address the effects that enhancing natural chemical signals might have on a whole ecosystem including the resident populations of insect-killing nematodes.
