Abstract: To explore the relation between calls rhythms and crickets behavior, this experiment were done with adult male Gryllus testaceus wallker, using mp3 for sounds recording, and using cooledit2000 and wavesurfer for analyzing the crickets' calls . Three different calls （alone,courtship,fight）and the their related behavior were studied. In the call peak period, the degree of Gryllus testaceus wallkers' courtship and fighting are more than that of the call low period.
