How Different Forms of Noise Influence Phonotaxis in Female Crickets.
Jessica Briggs, Daniel Howard. University of New Hampshire, Durham, NH, United States

Anthropogenic noise is a growing ecological concern that has wide ranging impacts on wildlife. Along with interrupting sensory perception, anthropogenic noise has been identified as an environmental stressor and can influence behavioral responses. Crickets can detect airborne noise in the low and high frequencies as well as substrate-borne vibrations and rely on detecting airborne calls to successfully locate males. A systematic approach was used to test the behavioral response of Australian black field crickets (Teleogryllus commodus) under variable noise conditions, with the aim of understanding how animal behavior is influenced by multisensory noise. Playback trials in the laboratory were performed to examine how noise in all three forms influenced female phonotaxis to male calling song. Females displayed an increase in duration, velocity, and time spent moving in the presence of airborne low frequency noise, regardless of noise intensity. This study will expand our knowledge of the effects of anthropogenic noise on an understudied taxa and highlight the importance of invertebrates in acoustic research.
