声音信号触发昆虫的各种行为，如求偶或逃离捕食者。然而，它仍然是未知的昆虫是否利用声信号来识别环境背景。蟋蟀是一个突出的模型昆虫的神经行为学研究的声音行为，因为女性蟋蟀表现出积极的趋声性，在响应男性呼叫歌曲，和飞行蟋蟀显示回避行为的高频声音，如回声定位呼叫蝙蝠。这些声音的载波频率是决定它们是否启动这些声学行为的主要因素。在这里，我们研究了不同频率的音调声音对cercal介导的逃避行为的影响，使用对应于呼叫歌曲的5 kHz音调和作为回避行为触发器的15 kHz音调。两种频率都没有引起站着的板球本身的反应，但它们对气流刺激的步行反应有不同的影响。虽然15 kHz音调降低了响应概率，延长了移动距离，并增强了转向角的可变性，但5 kHz音调没有影响。虽然两种频率的音调都有助于向后行走，但15 kHz的音调比5 kHz的音调有更大的影响。这些频率依赖性的行为调制表明，蟋蟀可以识别声环境，并相应地改变他们的逃生策略。
Acoustic signals trigger various behaviours in insects such as courtship or escape from predators. However, it remains unknown whether insects utilize acoustic signals to recognize environmental contexts. The cricket is a prominent model insect for neuroethological studies on acoustic behaviour because female crickets exhibit positive phonotaxis in response to male calling songs, and flying crickets display avoidance behaviour for high-frequency sounds such as echolocation call of bats. The carrier frequency of these sounds is a major factor in determining whether they initiate these acoustic behaviours. Here, we examined the impacts of different frequencies of tone sounds on cercal-mediated escape behaviour, using a 5-kHz tone corresponding to the calling song and a 15-kHz tone serving as a trigger of avoidance behaviours. Neither frequency elicited a response in the standing cricket by itself, but they had different impacts on walking responses to airflow stimuli. While the 15-kHz tone reduced response probability, extended moving distance, and enhanced turn-angle variability, the 5-kHz tone had no effect. Although both frequencies of tones facilitated walking backward, the 15-kHz tone had a larger effect than the 5-kHz tone. These frequency dependencies of behavioural modulation suggest that crickets can recognize acoustic contexts and alter their escape strategy accordingly.
