蚂蚁是结合了先天和后天的导航策略的专家。虽然我们知道蚂蚁的进食状态会隔离蚂蚁沿着学习路线导航时的视觉导航记忆，但动机状态是否也会影响蚂蚁天生的视觉偏好，这是一个悬而未决的问题。木蚁觅食者对明显的视觉线索表现出一种天生的吸引力。这些觅食者栖息在杂乱的林地栖息地，以树上蚜虫的蜜露为食。因此，对“树状”物体的吸引力可能是一种与生态相关的行为，是为木蚁的觅食生态量身定制的。具有不同觅食生态的其他蚂蚁种类的觅食者表现出非常不同的先天吸引力。本文研究了不同动机状态下木蚁觅食者的先天视觉反应，即未喂食、喂食和不觅食的雄蚁。我们的研究结果表明，这三组蚂蚁都倾向于一个突出的视觉线索，也就是说，这种内在的视觉运动反应不依赖于环境，而是在不同的动机和生态环境中看到的一种固有行为。在线版本包含补充资料，可在10.1007/s00040-022-00867-3获得。
Ants are expert navigators combining innate and learnt navigational strategies. Whereas we know that the ants’ feeding state segregates visual–navigational memories in ants navigating along a learnt route, it is an open question if the motivational state also affects the ants’ innate visual preferences. Wood ant foragers show an innate attraction to conspicuous visual cues. These foragers inhabit cluttered woodland habitat and feed on honeydew from aphids on trees. Hence, the attraction to ‘tree-like’ objects might be an ecologically relevant behavior that is tailored to the wood ants’ foraging ecology. Foragers from other ant species with different foraging ecologies show very different innate attractions. We investigated here the innate visual response of wood ant foragers with different motivational states, i.e., unfed or fed, as well as males that show no foraging activity. Our results show that ants from all three groups orient toward a prominent visual cue, i.e., this intrinsic visuomotor response is not context-dependent, but a hardwired behavior seen across different motivational and ecological contexts.
