Abstract

The acoustic display of many cricket species consists of trains of pulses chirps with intermittent pauses Here we investigated the temporal cues that females of the cricket Teleogryllus leo used to detect a pulse and a chirp pattern on two different time scales For both patterns females accepted a wide range of combinations that covered the respective pulse and chirp parameters in the songs of males In tests with a continuous series of pulses at different modulation frequencies the transfer function of pattern discrimination was also determined Females exhibited two ranges of high response scores indicating two temporal filters with an inhibitory interaction For the modulation frequency of the pulse pattern the peak of the preference function was rather sharply tuned and at a lower pulse rate than produced by males These results show that the combined output of both filters did not increase selectivity but rather enlarged the accepted range of signalsWe thank KlausGerhard Heller for discussions and critical reading of the manuscript The performed experiments comply with the “Principles of animal care” publication No 8623 revised 1985 of the National Institute of Health and also with the current laws of Germany Supported by SFB 618 ‘Theoretical Biology’
