Abstract
The acoustic environment that juveniles experience can be used as a cue to indicate their future adult environment. Novel sources of noise such as traffic and introduced species can disrupt previously reliable cues and may harm species that rely on acoustic signals for finding and choosing mates. To examine the effects of novel sounds during development, we raised female Gryllus pennsylvanicus crickets in four different acoustic environments: silence, conspecific song, the song of recently introduced heterospecific Velarifictorus micado, and traffic noise. After sexual maturity, we assayed female phonotaxis to conspecific male calling song. We found that females reared with conspecific song were choosier, taking longer to reach the speaker and spending less time near that speaker than females reared with traffic noise, silence, or heterospecific song. These results indicate that novel sounds during development do not affect mate-searching behaviors in female G. pennsylvanicus, but exposure to conspecific song does. Developing females are able to adaptively respond to cues from conspecifics while ignoring other ambient sounds.
