非洲蝼蛄(Gryllotalpa africana Palisot de Beauvois)的鸣声结构及声引诱

THE SOUND STRUCTURE AND ACOUSTIC ATTRACTION OF THE MOLE CRICKET GRYLLOTALPA AFRICANA PALISOT DE BEAUVOIS

本工作对北京地区非洲蝼蛄的鸣声结构作了详细分析;明确了在声通讯中起重要作用的参量并以其引诱力最强的召唤信号进行了声引诱实验。在成虫活动高峰期——晚间2小时38分钟内,平均一个声诱捕器捕获蝼蛄556只,最多的一个诱捕922只。

The structure of the calling song of the mole cricket G. africana Palisot de Beauvois in Beijing was finely analysed, and the main parameters in acoustic communication were determined. During the active peak period of the adults, one acoustic trap (main frequency 1.40 KHz, pulse rate 77/sec) caught 556 mole crickets in average and 922 at most in two hours andthirty eight minutes.
