虽然它已被证明，视觉线索发挥了至关重要的作用，在导航的花园antLasius尼日尔，没有以前的研究已经解决的方式，从当地的视觉线索的信息获取和利用导航。我们发现，在没有信息素踪迹的情况下，蚂蚁的归巢动机是由喂食引发的，它们会根据当地的视觉线索返回巢穴。在我们的实验中，蚂蚁穿过迷宫到达喂食器。他们在迷宫中探索，有时被困在死胡同里。我们发现，蚂蚁更有效地利用视觉线索在他们的回家之旅，如果他们经历了一个死胡同在他们的外出之旅。这一结果表明，蚂蚁在向外的旅程中使用从视觉线索获得的信息，以避免在返回途中进入死胡同。
Although it has been shown that visual cues play an essential role in navigation by the garden antLasius niger, no previous studies have addressed the way in which information from local visual cues is acquired and utilized in navigation. We found that in the absence of pheromone trails, ants whose homing motivation was triggered by feeding returned to the nest following local visual cues. In our experiments, the ants travelled through a maze to reach a feeder. They explored the maze and sometimes became trapped in its dead ends. We found that the ants more effectively used visual cues during their homeward journey if they experienced a dead end during their outward journey. This result suggested that the ants used the information acquired from visual cues during the outward journey to avoid a dead end on their return journey.
