Continuous jumping behavior, a kind of endurance locomotion, plays important roles in insect ecological adaption and survival. However, the methods used for the efficient evaluation of insect jumping behavior remain largely lacking. Here, we developed a locomotion detection system named JumpDetector with automatic trajectory tracking and data analysis to evaluate the jumping of insects. This automated system exhibits more accurate, efficient, and adjustable performance than manual methods. By using this automatic system, we characterized a gradually declining pattern of continuous jumping behavior in 4th-instar nymphs of the migratory locust. We found that locusts in their gregarious phase outperformed locusts in their solitary phase in the endurance jumping locomotion. Therefore, the JumpDetector could be widely used in jumping behavior and endurance locomotion measurement.
连续跳跃行为是一种耐力运动，在昆虫的生态适应和生存中起着重要作用。然而，用于有效评估昆虫跳跃行为的方法在很大程度上仍然缺乏。在这里，我们开发了一种名为 JumpDetector 的运动检测系统，具有自动轨迹跟踪和数据分析功能，用于评估昆虫的跳跃行为。与手动方法相比，这种自动化系统具有更准确、高效和可调节的性能。通过使用这种自动系统，我们描绘了群居期 4 龄若虫连续跳跃行为逐渐下降的模式。我们发现，群居期的蝗虫比独居期的蝗虫在耐力跳跃运动中表现更好。因此，JumpDetector 可以广泛应用于跳跃行为和耐力运动的测量。
