Investigations on the locomotor behaviour of females of the bushcricketEphippiger ephippiger were carried out. Their behaviour was observed on a multibranched plant in the laboratory while both conspecific song and a simultaneously transmitted vibratory signal were applied to the plant. As soon as the insects reached a certain level in the bush the acoustic stimulus was switched off and only vibratory cues (tremulation) remained. Observations were then made of females using these vibratory signals to orientate towards the source of the vibratory signals (artificial male). The females were attracted at short distance (58 cm) only. At a longer distance (105 cm) the insects did not show definite vibrotaxis. A comparison which was made to an experiment with conspecific song and simultaneously transmitted vibration revealed that females were much more attracted by these combined stimuli. Here the females made a lower number of interruptions and reached the emitter faster than if stimulated with tremulation alone.
对 Bushcricket Ephippiger ephippiger 雌性的运动行为进行了研究。在实验室中，当同时向植物施加同种鸣声和同时传输的振动信号时，观察到它们在多分支植物上的行为。一旦昆虫到达灌木丛中的某个特定高度，就会关闭声刺激，只留下振动线索（震颤）。然后观察雌性利用这些振动信号来定位振动信号（人工雄性）的来源。雌性只在短距离（58 厘米）被吸引。在更长的距离（105 厘米），昆虫没有表现出明确的趋振性。与具有同种鸣声和同时传输振动的实验进行比较表明，雌性对这些组合刺激的吸引力更大。在这里，雌性中断的次数更少，到达发射器的速度也比单独受到震颤刺激时更快。
