Entomopathogenic nematodes are obligate lethal parasitoids of insect larvae that
navigate a chemically complex belowground environment while interacting with
their insect hosts, plants, and each other. In this environment, prior exposure
to volatile compounds appears to prime nematodes in a compound specific manner,
increasing preference for volatiles they previously were exposed to and
decreasing attraction to other volatiles. In addition, persistence of volatile
exposure influences this response. Longer exposure not only increases preference,
but also results in longer retention of that preference. These entomopathogenic
nematodes display interspecific social behavioral plasticity; experienced
nematodes influence the behavior of different species. This interspecific social
behavioral plasticity suggests a mechanism for rapid adaptation of belowground
communities to dynamic environments.
