InGryllodinus kerkennensis the essential property of the signal is the continuity of the song (Fig 3).
InGryllus campestris andG. bimaculatus pulse rate and chirp duration are important, the former having narrow and the latter broad tuning of reaction to chirp duration (Fig. 4).
InSpecies 2 (see Methods) chirp rate and pulse duration determine the specific response of females (Figs. 5 and 6).
InMelanogryllus desertus the most important parameters are the mean pulse rate and the increase in amplitude of pulses within the chirps (Fig. 7).
The spectrum of the CS is not important for the process of recognition as far as it falls into the tuning curve of specialized low-frequency channel of the auditory system. High-frequency sounds outside the range of this channel are not effective even if they have the same amplitude modulation pattern as the CS.
The properties of phonotactic reaction of crickets are discussed. It is concluded that the system controlling the reaction works on the probability principle.
