蟋蟀对召唤声识别的趋声性定位行为

Phonotactic position-fixing behavior of recognition on calling song in crickets

为了探究蟋蟀种内个体间的声音通讯原理,本研究通过回放利用Cool-edit2000声音采集软件采集的双斑蟋Gryllus bimachlatus召唤声,分别对雌、雄蟋蟀识别召唤声的趋声性定位行为进行了观测研究。实验结果表明:雌、雄双斑蟋对回放的召唤声均有较强的识别反应,但雌蟋蟀的趋声定位性较强,能在较短的时间内积极寻找到声源,路径成"s"型;雄蟋蟀反应相对较弱,路径较长,找到声源时间比雌蟋蟀长。本研究结果揭示召唤声在蟋蟀种内通讯中不仅对个体间的联系有作用,对异性求偶也有重要作用。

In order to investigate the role of the recognition principle in cricket song we studied the phonotactic position-fixing behavior of male and female crickets（Gryllus bimachlatus）.Our results show that the song of a conspecific male cricket can elicit phonotactic responses of both females and males,but the phonotactic movements of females towards singing males were stronger and shorter,in terms of reaction time,than those of males.The female pattern of phonotactic approaches was sigmoid.These results reveal that the song of male crickets not only affects the behavior of male conspecifics but also attracts females for courtship.
