摘要
对两种常见树蟋长瓣树蟋Oecanthus longicauda Matsumura和黄树蟋O.rufescens Serville的召唤声特征进行了比较研究。研究结果表明,两种树蟋召唤声的时域特征和频域特征在脉冲组所含脉冲数、脉冲组持续时间、脉冲组间隔时间、脉冲组脉冲排列规律、单脉冲间隔时间、频域能峰数和能峰值等方面存在明显差异。长瓣树蟋脉冲组主要由3个脉冲组成,含3个脉冲的脉冲组持续时间约0.049±0.001s,脉冲组间隔时间为0.027±0.003s,单脉冲持续时间约0.011±0.001s,单脉冲间隔时间约0.009±0.001s,频谱图只有1个2.5KHz的主能峰。黄树蟋脉冲组由16～20个脉冲组成,脉冲组持续时间为0.303±0.021s,脉冲组间隔时间为0.401±0.046s,单脉冲持续时间约为0.012±0.001s,脉冲间隔时间约为0.004±0.001s,频谱图有两个能峰:主能峰频率为3.03KHz,次能峰频率为16.78KHz。
We conducted a comparative study on calling songs of two common tree crickets Oecanthus longicauda Matsumura and O. rufescens Serville. The results show that calling song＇s time-domain characteristics and frequency domain characteristics of two tree crickets vary significantly in pulses of chirp, chirp length, interchirp length, pulse length, interpulse length, peak frequency. Pulse group of O. longicauda Matsumura mostly is composed of three pulses with the chirp duration about 0.049±0.001 s, interchirp length of 0.027±0.003 s. Single-pulse duration is about 0.011±0.001 s, interpulse length of about 0.009±0.001 s, only a 2.5 KHz dominant peak. Pulse group of O. rufescens Serville contains 16 to 20 pulses, chirp duration of 0.303±0.021 s, interchirp length about 0.401±0.046 s. Single-pulse duration is about 0.012 ± 0.001 s, pulse interval about 0.004 ± 0.001 s. Frequency spectrum has two peaks： dominant peak at 3.03 KHz, second peak at 16.78 KHz.
