摘要
应用计算机技术分析了内蒙古草原乌苏里蝈螽Gampsocleis ussuriensis和优雅蝈螽Gampsocleis gratiosa2种螽斯雄性的鸣声结构。乌苏里蝈螽鸣声较复杂,一次鸣叫持续时间6-27s（平均12.5s）,每个脉冲组由两类脉冲组组分构成,第1类脉冲组组分为振幅较大的脉冲组,脉冲组持续时间0.0065s,由6-8个脉冲串组成,每个脉冲串持续时间为0.00047s,间隔时间为0.00027s,每个脉冲串含5-10个单脉冲,脉冲串持续时间、间隔时间较短;第2类脉冲组组分为振幅较小的脉冲组,脉冲组持续时间0.0191s,约含有15个左右脉冲串,持续时间为0.00041s,间隔时间约为0.00127s,每个脉冲串含有3-5个单脉冲,脉冲串持续时间、间隔时间也较短,主能峰频率为7.98kHz。优雅蝈螽鸣声则较规则,一次鸣叫持续时间4-232s（平均41.7s）。每个脉冲组也由两类脉冲组组分构成,第1类脉冲组组分振幅较大且逐步增强,脉冲组持续时间0.119s,由10个振幅较大的脉冲串组成,每个脉冲串持续时间为0.00576s,间隔时间为0.005s,每个脉冲串含18-25个单脉冲;第2类脉冲组组分为振幅较小的脉冲组,脉冲组持续时间0.07s,约含有25个左右脉冲串,脉冲串振幅较小,含有6-9个单脉冲,主能峰频率为6.87kHz,次能峰频率为3.25kHz。结果表明乌苏里蝈螽与优雅蝈螽雄性鸣声既有相似的共同特征,同时存在较显著差异。
The characters of male song of two species of tetfigonids from Inner Mongolia Steppe were analyzed by using technology of computer. The sequences of male songs of Gampsodeis Adelung lasts 6-27 s （Mean = 12.5 s）, which are complicated with two types of components in a chirp, the first type of component with larger amplitude lasts 0.0065 s, consisting of 6-8 pulsestrings, the duration of each pulse-strings is 0.00047 s, consisting of 5-10 monopulses with inter-pulse-string interval of 0.00027 s, the pulse-string duration and interpulse-string interval are shorter; the second type of component with smaller amplitude lasts 0.0191 s, consisting of 15 pulse-strings with decreased amplitude, the duration of each pulse-strings is 0.00041 s, containing 3-5 monopulses with inter-pulse-string interval of 0.00127s, the pulse-string duration and inter-pulse- string interval are also shorter, and the frequency of highest power peak is about 7.98 kHz. The sequences of male songs of Gampsodeis gratiosa Brunner lasts 4-232 s （Mean = 41.7 s）, which are also regular with two types of components in a chirp, the first larger ampfitude component has increased amplitude gradually, lasts 0.119 s, consisting of 10 pulse-strings, the duration of each pulse-strings is 0.00576 s and the inter-pulse-string interval is 0.005 s, containing 18-25 low-amplitude monopulses; the second samller amplitude component lasts 0.07 s, consisting of about 25 pulse-strings with lowamplitude, each pulse-string containing 6-9 monopulses, and the frequency of the two highest power peak are 6.87 kHz and 3.25 kHz. The results shown that the male songs of two species of tettigonids have common characteristics, but there are also significant differences.
