The innervations of sounding movements are synchro-controlling type for some species and asynchro-controlling type for other species. The contracting movements of sounding muscles on both sides are synchronous for some species and alternate for other species, and the contracting frequencies are from several decade to several hundred and generally below 500 Hz. On the basis of studies on the song property and innervation of sound production in the Mingnfing cicada, the innervation frequency-response of movements in sounding muscles is studied in this note. The results provide the important basis for expounding the sounding mechanism of vari-toned songs in cicadas.展开更多
