四种蝗虫雄性鸣声的比较研究(直翅目,蝗总科)

A COMPARATIVE STUDY ON THE MALE SONG STRUCTURES OF FOUR SPECIES OF GRASSHOPPERS(ORTHOPTERA, ACRIDOIDEA)

应用计算机技术分析了肿脉蝗Stauroderusscalarisscalaris (Fischer Waldheim)、宽须蚁蝗Myrmeleotettixpalalis(Zubowsky)、邱氏异爪蝗EuchorthippuscheuiHsia、西伯利亚蝗Aeropussibiricus(Linnaeus)雄性的鸣声特征。这 4种蝗虫雄性鸣声特征差异显著。肿脉蝗雄性鸣声具有脉冲序列的分化 ,每个脉冲序列分为两种不同的脉冲组 ,第 1种脉冲组持续时间约 0 0 81s,有 7个脉冲串组成 ,每个脉冲串有 7个单脉冲构成 ;第 2种脉冲组持续时间不等 ,有 13～ 18个脉冲串组成 ,脉冲串持续时间为 0 0 2 1s,间隔为 0 0 10s。鸣声的主能峰频率约 8 6 2kHz。宽须蚁蝗雄性鸣声的脉冲组持续时间为 0 2 3s,脉冲组间隔为 0 35s,每个脉冲组由 2 8～ 31个单脉冲组成 ,主能峰频率为6 89kHz、 12 75kHz。邱氏异爪蝗雄性鸣声的脉冲组持续时间为 0 2 2s,脉冲组间隔为 0 76s,每个脉冲组由 6～ 7个脉冲串组成 ,每个脉冲串内含有 1～ 5个单脉冲 ,主能峰频率为 9 6 5kHz。西伯利亚蝗的脉冲组持续时间约为0 0 92s,脉冲组间隔为 0 0 8s,每个脉冲组分化为 5～ 6个脉冲串 ;主能峰频率为 7 5 8kHz。

This paper analyzed the male song structures of four grasshoppers by using technology of computer. There are distinguished differences between the male songs of the four grasshoppers. The sequences of the male songs of Stauroderus scalaris scalaris(Fischer-Waldheim)include two types of chirps. The chirp of the first type lasts 0.081s, consisting of 7 pulse-strings and each pulse-string includes 7 pulses. The chirp of the second part includes 13-18 pulse-strings and the duration of each pulse -string is 0.021s with inter-pulse-string interval of 0.010s. The high power peak is about 8.62kHz.There are 28-31 pulses in each chirp of the male songs of Myrmeleotettix palalis(Zubowsky),the chirp lasts 0.23s with inter-chirp interval of 0.35s,and two high power peaks are about 6.8kHz, 12.75kHz respectively. The chirp of the duration of the songs of Euchorthippus cheui Hsia is 0.20. The interchirp interval is 0.79s. Each chirp consists of 6-7 pulse-strings and each pulse-string includes 1-5 pulses. The high power peak is about 9.65kHz. The chirp of Aeropus sibiricus(Linnaeus)consists of 5-6 pulse-strings. The chirp duration and inter-chirp interval are 0.092s, 0.080 respectively. The high power is about 7.58kHz.
