Exposure to constitutive and herbivore induced plant volatiles appears to prime nematodes in a compound specific manner, increasing preference for volatiles to which they were previously exposed and decreasing attraction to other volatiles. Duration of exposure also influences the learning ability and memory of entomopathogenic nematodes; longer exposure not only increases preference, but also results in longer retention of that preference. In addition, these entomopathogenic nematodes display interspecific social behavioral plasticity; experienced nematodes alter the behavior of different species. The learning behavior, memory and interspecific transfer of learned information in a social context suggest a mechanism for rapid adaptation of belowground communities to dynamic environments and can inform development of practical biocontrol applications. |
