许多动物发出声音信号来标记领地和吸引配偶。当不同的物种同时产生声信号时，这些信号会产生一个嘈杂的环境，物种之间存在潜在的声干扰。理论研究表明，这种生殖干扰可能对物种相互作用有很强的影响。例如，如果劣势资源竞争者的劣势被生殖干扰的优势所抵消，那么劣势资源竞争者就可以生存。两种野地蟋蟀（直翅目：灰蟋蟀科）和两种野地蟋蟀（直翅目：灰蟋蟀科）在同一生境孳生。之前的一项研究表明，l。马属一劣等种。在资源竞争方面的社会主义。因此，我们预测了雌性雄性的择偶和选择行为。枕部会受到l的声信号的负面影响。Equestrisand通过一系列回放实验验证了这一点。雌性的择偶行为。枕骨症不受l的鸣叫声的显著影响。equestris。我们的研究结果表明，声干扰不能解释两种物种在同一栖息地的共存。
Many animals produce acoustic signals to mark territories and attract mates. When different species produce acoustic signals simultaneously, the signals create a noisy environment, with potential acoustic interference between species. Theoretical studies suggest that such reproductive interference may have strong effects on species interaction. For example, the inferior resource competitor can survive if its disadvantage is counterbalanced by superiority in reproductive interference. Two field cricket species,Teleogryllus occipitalis(Audinet-Serville) (Orthoptera: Gryllidae) andLoxoblemmus equestrisSaussure (Orthoptera: Gryllidae), cooccur in the same habitat. A previous study has shown thatL. equestrisis an inferior species toT. occipitalisin terms of resource competition. Therefore, we predicted that mate location and choice behavior of femaleT. occipitaliswould be negatively affected by the acoustic signals ofL. equestrisand tested this with a series of playback experiments. The mate choice behavior of femaleT. occipitaliswas not significantly affected by the calling song ofL. equestris. Our results suggest that the acoustic interference does not explain the cooccurrence of the two species in the same habitat.
