摘要
比较分析了戈壁硕螽(Zichya gobica)和大棘螽(Deracantha grandis)的鸣声特征.研究结果表明两者的鸣叫特征有所不同.戈壁硕螽鸣声的每个脉冲组由4个脉冲构成,脉冲组持续时间为0.007 s±0.000 2 s,脉冲组间隔很短,主能峰频率15 KHz.大棘螽鸣声的每个脉冲由10个~11个脉冲串构成,脉冲组持续时间为0.02±0.002 s,脉冲组间隔极短,主能峰频率为13 KHz.
In this paper we analyzed the male calling song structures of Zichya gobica and Deracantha grandis.The result shows that the song structures of Zichya gobica and Deracantha grandis have some differentia.The chirp of the songs of Zichya gobica lasts 0.007 s±0.000 2 s,consisting of 4 pulse and the frequency of highest power peak is about 15 KHz.The chirp of the songs of Deracantha grandis has 10~11 pulse,the pulse duration is 0.02 s±0.002 s and the frequency of highest power peak is about 13 KHz.
