东方雏蝗不同地理种群雄性鸣声结构的比较研究

比较分析了东方雏蝗Chorthippus intermedius B.-Bienko的竞争鸣叫声和3个不同地理种群的召唤声。研究结果表明,东方雏蝗3个不同地理种群召唤声时域特征大致相同,在脉冲组持续时间与频域特征上,山西中条山种群与吉林松花湖种群较相似,黑龙江镜泊湖种群与前二者差异稍明显。黑龙江镜泊湖种群的竞争声由2~4个脉冲组组成的脉冲序列组成,其脉冲组的基本结构与召唤声相同,但脉冲组持续时间相对较短。

A COMPARATIVE STUDY ON THE MALE SONGS OF DIFFERENT GEOGRAPHICAL POPULATIONS OF CHORTHIPPUS INTERMEDUS (B. -BIENKO)

This paper analyzed the male calling song structures of three geographical populations and rivalry song structure of Chorthippus intermedius. The result shows that the calling songs of three geographical populations contain the same composition. The characters of oscillogram and spectra of Jiling and Shanxi populations are more alike, but those of Heilongjiang population are different from them. The oscillogram of rivalry song of Heilongjiang population is composed of sequence contained 2-4 chirps. The fundamental compositions of oscillogram and spectra are similar to that of calling song.
