Male courtship songs of 9 grasshopper species of Gomphocerinae from Kazakhstan and Orenburg region and Altai Republic of Russia were studied. We analyzed not only the sound, but also the stridulatory movements of the hind legs to more entirely describe the songs. We also analyze the frequency spectra of the songs and the whole visual display during courtship. The courtship songs of three species, Stenobothrus miramae, Chorthippus dubius and Ch. angulatus, were studied for the first time. In four species, Omocestus haemorrhoidalis, O. petraeus, Myrmeleotettix pallidus, Ch.karelini, we found certain differences in temporal pattern of the courtship songs in comparison with the previous data on the respective species from other regions. In five species, O. viridulus, S. miramae, M. pallidus, Ch. dubius and Ch. karelini, various parts of elaborate courtship songs differed in the carrier frequency. In four species, O. haemorrhoidalis, O. petraeus, M. pallidus and Ch. dubius, the dominant frequencies of the courtship song were shown to lie in the range higher than 20 kHz. The conspicuous movements of antennae and legs during courtship were studied in M. pallidus, S. miramae and Gomphocerus sibiricus.
我们研究了来自哈萨克斯坦和俄罗斯奥伦堡地区及阿尔泰共和国的 9 种蝗科蚱蜢雄虫的求爱歌曲。我们不仅分析了声音，还分析了后腿的摩擦动作，以更全面地描述歌曲。我们还分析了求爱歌曲的频率谱和整个视觉展示。这是首次研究三种物种，即 Stenobothrus miramae、Chorthippus dubius 和 Ch. angulatus 的求爱歌曲。在 4 种物种，Omocestus haemorrhoidalis、O. petraeus、Myrmeleotettix pallidus 和 Ch.karelini 中，我们发现与其他地区的各自物种的先前数据相比，求爱歌曲的时间模式存在某些差异。在 5 种物种，O. viridulus、S. miramae、M. pallidus、Ch. dubius 和 Ch. karelini 中，精心制作的求爱歌曲的各个部分在载波频率上存在差异。在 4 种物种，O. haemorrhoidalis、O. petraeus、M. pallidus 和 Ch. dubius 中，求爱歌曲的主频被显示为高于 20 kHz 的范围。在 Myrmeleotettix pallidus、Stenobothrus miramae 和 Gomphocerus sibiricus 中研究了求爱过程中触角和腿部的明显运动。
