Escape behavior is essential for animals to avoid attacks by predators. In some species, multiple escape responses could be employed. However, it remains unknown what aspects of threat stimuli affect the choice of an escape response. We focused on two distinct escape responses (running and jumping) to short airflow in crickets and examined the effects of multiple stimulus aspects including the angle, velocity, and duration on the choice between these responses. The faster and longer the airflow, the more frequently the crickets jumped. This meant that the choice of an escape response depends on both the velocity and duration of the stimulus and suggests that the neural basis for choosing an escape response includes the integration process of multiple stimulus parameters. In addition, the moving speed and distance changed depending on the stimulus velocity and duration for running but not for jumping. Running away would be more adaptive escape behavior.
逃避行为对于动物躲避捕食者的攻击至关重要。在某些物种中，可以采用多种逃避反应。然而，威胁刺激的哪些方面会影响逃避反应的选择仍不清楚。我们聚焦于蟋蟀对短气流的两种不同逃避反应（奔跑和跳跃），并研究了包括角度、速度和持续时间在内的多个刺激因素对这些反应之间选择的影响。气流越快、持续时间越长，蟋蟀跳跃的频率就越高。这意味着逃避反应的选择取决于刺激的速度和持续时间，并且表明选择逃避反应的神经基础包括多个刺激参数的整合过程。此外，奔跑的移动速度和距离会根据刺激速度和持续时间而变化，但跳跃则不会。逃跑可能是更具适应性的逃避行为。
