Analysis of Acoustic Communication by Ants


Analysis of Acoustic Communication by Ants

R Hickling et al. J Acoust Soc Am.


An analysis is presented of acoustic communication by ants, based on near-field theory and on data obtained from the black imported fire ant Solenopsis richteri and other sources. Generally ant stridulatory sounds are barely audible, but they occur continuously in ant colonies. Because ants appear unresponsive to airborne sound, myrmecologists have concluded that stridulatory signals are transmitted through the substrate. However, transmission through the substrate is unlikely, for reasons given in the paper. Apparently ants communicate mainly through the air, and the acoustic receptors are hairlike sensilla on the antennae that respond to particle sound velocity. This may seem inconsistent with the fact that ants are unresponsive to airborne sound (on a scale of meters), but the inconsistency can be resolved if acoustic communication occurs within the near field, on a scale of about 100 mm. In the near field, the particle sound velocity is significantly enhanced and has a steep gradient. These features can be used to exclude extraneous sound, and to determine the direction and distance of a near-field source. Additionally, we observed that the tracheal air sacs of S. richteri can expand within the gaster, possibly amplifying the radiation of stridulatory sound.
