摘要：应用开发设计的昆虫声音采集与录制系统,对在不同实验条件下(玻璃板夹心、木段钻孔、室外直接测定)的红脂大小蠹两性成虫声音信号进行了采集、放大与数字化记录,并应用Adobe Audition与matlab软件分别对雌雄成虫的胁迫声、雄虫求偶声、雄虫竞争声、雌虫回应声等声音信号进行了脉冲组、频率、持续时间、频谱等特征分析,此外,还应用扫描电镜对其摩擦发声器官进行了观察与记录。研究结果表明:红脂大小蠹整体摩擦声音频率为35.3 kHz;雌雄间声音有显著区别,其摩擦发音结构音锉也有明显不同;而不同行为下所发出的声音信号在时域和频域上也略有差异,显示其与行为交流密切相关。
The bioacoustic signals often work alone or together with other signals like visual or olfactory signals in insect communication.The adult stridulatory signals of red turpentine beetle（RTB）,Dendroctonus valens,were recorded and stored digitally after amplification in three experiments（glass phloem sandwich rearing,bolt rearing and directly field recording）.The signals in different behavior were then analyzed by a specific acoustic software Adobe Audition and Matlab for echeme,duration,frequency,time domain and frequency domain analysis.The stridulatory apparatus of both male and female were observed by scanning electron microscope.The result showed that the frequency of the stridulatory sound by D.valens was from 3 kHz to 5.3 kHz,and there were clearly differences between the males and females,both in the sounds frequency and in apparatus structure.There were slightly differences with the signals recorded in different behavior,which proved the signals played a role in RTB behavior.
