temperature dependence of cicada songs (homoptera, cicadoidea).	the songs of male portuguese cicadas tettigetta argentata, t. josei and tympanistalna gastrica were recorded at five to seven temperatures within the range 24-38.5 degrees c. to investigate the temperature dependence of the neuromuscular apparatus involved in song production, different temporal elements of the calling songs were measured. we report a strong temperature dependence for the syllable and the echeme rates in t. josei and ty. gastrica. this suggests that in these species the neuromusc ...	2002	11913815
phasic action of the tensor muscle modulates the calling song in cicadas	the effect of tensor muscle contraction on sound production by the tymbal was investigated in three species of cicadas (tettigetta josei, tettigetta argentata and tympanistalna gastrica). all species showed a strict time correlation between the activity of the tymbal motoneurone and the discharge of motor units in the tensor nerve during the calling song. lesion of the tensor nerve abolished the amplitude modulation of the calling song, but this modulation was restored by electrical stimulation ...	1996	9319436
