Description

The intensity of the calling songs to which a female cricket Acheta domesticus is most likely to start responding phonotactically has been reported to be around 55dB at a carrier frequency of 4 – 5 kHz. These reports, however, have not shown selective phonotaxis to occur at such low intensities. Preliminary data from behavioral experiments have demonstrated that i) in response to calling songs with intensities above 75dB, females are more likely to exhibit selective phonotaxis in response to a full sequence of calling songs with varying syllable periods (30 – 90 ms); ii) in response to calling songs with intensities below 75 dB the same females are less likely to respond selectively to identical stimuli. By testing all three intensities, 85dB, 75dB, and 60dB, at various syllable periods, we intend to find the threshold intensity at which a female cricket will exhibit selectivity in their phonotactic choices.
