在昆虫中，产生声音的各种方式已经进化为物种内部和物种之间的交流。雄蝉以其由鼓膜器官发出的响亮而多样的歌声而闻名。一些鸟类的雌性可以通过拍打翅膀来回应雄性的叫声。杨氏盐藻（Subpsaltria yangi）的独特之处在于，除了雄性的鼓膜器官外，它还具有在两性中都发现的发育良好的发声器官。在这里，我们调查的声音生产和交配行为的这一物种。我们发现，在对形成的背景下，女性产生的声音信号的鸣叫，以响应男性与鼓膜器官产生的广告信号。我们还发现，雄蝉的发声器官所产生的声音是非常相似的声学结构，女性，这表明男性模仿的信号，由女性在配对形成。声音回放实验表明，通过产生类似雌性的声音信号，雄性可以欺骗接受的雌性将其视为竞争对手，这使得雄性更有效地引起接受雌性的声音反应。因此，雄性可以通过模仿雌性的声音信号来获得生殖利益，因为它们主要依靠雌性的声音反应来寻找雌性。我们的研究提供了第一个实验证据，声音生产的一个颤音机制在蝉，和一个新的情况下，种内性模仿的基础上声学相似性。(C)2015年动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
In insects various ways to produce sounds have evolved for communication both within and between species. Cicada males are particularly known for their loud and diverse songs which are produced by tymbal organs. Females of some cicada species can produce sounds by wing flicking in response to male calls. The cicada species Subpsaltria yangi is unusual in that, besides the tymbal organs of males, it has well-developed stridulatory organs that are found in both sexes. Here, we investigated sound production and mating behaviour of this cicada species. We show that, in the context of pair formation, females produced sound signals by stridulation in response to advertisement signals produced by males with tymbal organs. We also found that the sounds produced by male cicadas with stridulatory organs were extremely similar in acoustic structure to those of females, which indicates that males mimic the signals produced by females during pair formation. Acoustic playback experiments suggested that, by producing female-like sound signals, a male could deceive a receptive female into treating him as a rival female, which makes the male more effective in eliciting acoustic responses from the receptive female. Therefore, the males could gain reproductive benefit by mimicking female sound signals, since they rely primarily on females' acoustic responses to find females. Our study provides the first experimental evidence for sound production by a stridulatory mechanism in cicadas, and a novel case of intraspecific sexual mimicry based on acoustic similarity.
