...Kaveri Rajaraman; Vamsy Godthi; Rudra Pratap; Rohini Balakrishnan ABSTRACT The communication strategy of most crickets and bushcrickets typically consists of males broadcasting loud acoustic calling songs, while females perform phonotaxis, moving towards the source of the call. Males...

...Ismene Fertschai; Jürgen Stradner; Heiner Römer SUMMARY Imperfect synchrony between male calls occurs in the acoustically interacting bushcricket Mecopoda elongata , and males establishing the temporal leadership attract more females in choice experiments. An asymmetrical representation of leader...

...Winston J. Bailey; Thomas J. Hammond SUMMARY Duetting is common between the sexes of phaneropterine bushcrickets(Phaneropterinae: Tettigoniidae: Orthoptera). In this paper we describe the complex duet of an undescribed Australian species within the genus Caedicia . The male's call consists of three...

... tuning bushcricket hearing threshold call spectrum sound transmission Communication systems are only functional when there is a sufficient match between the signal properties and the sensitivity of the receiver. In the case of an acoustic communication system, the hearing organs are usually...

...Winston J. Bailey; Suanne Yang SUMMARY Fluctuating asymmetry in bilaterally placed sensory structures of insects may be considered maladaptive; natural selection should favour a symmetrical system. Among bushcrickets or katydids, threshold hearing sensitivity is, in part, dependent on the size...

...), but also serves for the detection of predators. For many insects in the family Tettigoniidae (katydids, bushcrickets or long-horn grasshoppers), the species-specific mate-calling song is broadband and contains both audio (<20 kHz) and ultrasonic (⩾20 kHz) frequencies (e.g. Keuper et al., 1988...

...E. Tauber; M. P. Pener ABSTRACT Unlike most acoustic systems evolved for pair formation, in which only males signal, in many species of phaneropterine bushcrickets both sexes sing, producing a duet. We used the duetting species Phaneroptera nana as a model to explore the cues in the male’s song...

...Andreas Stumpner ABSTRACT The interneurone AN5-AG7 of the duetting bushcricket Ancistrura nigrovittata has its soma in the seventh (penultimate) abdominal ganglion. Its major postsynaptic arborizations with dense thin branches of smooth appearance are found in the prothoracic ganglion. The branches...

...Heiner Römer; Winston Bailey ABSTRACT The carrier frequency of the call of the Australian bushcricket Sciarasaga quadrata is unusually low for tettigoniids at 5 kHz. The sound transmission measured in the habitat of the insect reflects the advantages of producing low-rather than high-frequency...

...A. Stumpner ABSTRACT An auditory interneurone (AN1) of the bushcricket Ancistrura nigrovittata is described; it has a soma and dendrites in the prothoracic ganglion, an ascending axon and axon collaterals in the protocerebrum. As judged from morphological and physiological similarity...

...Christos Consoulas; Reinhold Hustert; George Theophilidis ABSTRACT Most abdominal sternites of the cricket Gryllus bimaculatus and the bushcricket Decticus albifrons are bridged by a transverse muscle (TM) which supports expiratory movements. In the cricket, ventilatory contractions are controlled...
