外来入侵物种威胁世界各地的生物多样性，并有助于生物同质化，特别是在淡水中，因为当地动物的分散能力有限。机器人可能会提供一个很有希望的工具来解决这个紧迫的问题，但入侵物种是否以及如何会受到机器人刺激的负面影响是一个悬而未决的问题。在这里，我们探索通过改变机器人捕食者的仿生程度来调节蚊子的行为和生活史反应的可能性，机器人捕食者的外表和运动受到天然蚊子捕食者的启发。我们的结果支持这样的预测，即与机器人简单的运动模式相比，在不同游泳速度下的实时交互在蚊子身上激起了更强大的抗捕食者反应，特别是在身体状况更好、不太容易冒险的人身上。通过对动物-机器人相互作用的信息论分析，我们提供了支持机器人捕食者运动和鱼类反捕食者反应之间因果联系的证据。值得注意的是，我们观察到，即使是每周短暂接触这种机器人捕食者15分钟，也足以侵蚀能量储备，危及蚊子的身体状况，为未来在野外控制蚊虫的努力打开了大门。
Invasive alien species threaten biodiversity worldwide and contribute to biotic homogenization, especially in freshwaters, where the ability of native animals to disperse is limited. Robotics may offer a promising tool to address this compelling problem, but whether and how invasive species can be negatively affected by robotic stimuli is an open question. Here, we explore the possibility of modulating behavioural and life-history responses of mosquitofish by varying the degree of biomimicry of a robotic predator, whose appearance and locomotion are inspired by natural mosquitofish predators. Our results support the prediction that real-time interactions at varying swimming speeds evoke a more robust antipredator response in mosquitofish than simpler movement patterns by the robot, especially in individuals with better body conditions that are less prone to take risks. Through an information-theoretic analysis of animal-robot interactions, we offer evidence in favour of a causal link between the motion of the robotic predator and a fish antipredator response. Remarkably, we observe that even a brief exposure to the robotic predator of 15 min per week is sufficient to erode energy reserves and compromise the body condition of mosquitofish, opening the door for future endeavours to control mosquitofish in the wild.
