摘要
为探索蟋蟀不同鸣叫声的发声原理,以双斑蟋(Gryllus bimachlatus)成虫为实验材料,用Cool-edit2000声音采集软件记录、分析,同时用数码照像机抓拍蟋蟀各种鸣叫瞬间的翅膀位置,分析测量不同鸣叫声时翅膀与身体所成的角度,对蟋蟀的三种不同鸣叫声的发声结构进行了研究.结果发现,蟋蟀发出不同的鸣叫声,与发声时翅膀相对身体抬高的角度有关.召唤声(Calling sound,CS)约42度、求偶声(Courtship sound,CSS)约32度、争斗声(Rival sound,RS)约53度.研究结果为进一步探究昆虫的鸣叫发声原理提供了更为直观的依据.
In order to explore the principle of sound of the cricket＇ s different sounds , we regarded adult Gryllus bimachlatus as experiment materials, recorded and analyzed with the sounds acquisition software Cool-edit 2000, took photographs in random to record changes of position of cricket＇s wings, measure and analyze angles between the wing and the body when the cricket send out different sounds, and reseach the wocalism＇s structure of the cricket＇s different sound. The result suggests that cricket＇s different sounds connect with the rising angle of the wing relative to the body. The angle of the calling sound is 42 degree; the courtship sound is 32 degree; and the rival sound is 53 degree. It provides more intuitional basis for further investigation of principle of sounds of insect.
