摘　　要：定量研究了铺道蚁Tetramoriumcaespitum的载物返巢行为。实验证明这种蚂蚁在获得食物后 ,并不重复搜寻食物期间所走过的迂回路线 ,而是沿着近似直线的新路径迅速回巢。太阳及天空偏振光模式能用作它们返巢的提示 ,非偏振光源也能指引蚂蚁成功地捷径返巢。这些结果表明有高级社会性结构的铺道蚁通过脑以光导航。Homing behaviour in the ant, Tetramorium caespitum, with food was quantitatively studied. We demonstrate that after obtaining food the ant workers are able to rapidly return to their nest along a new, ‘bee line’ route and are not bound to retrace their outward tortuous routes during foraging. The sun and polarized skylight pattern can be used as a cue for homing, and a non polarized lighting can guide the ant home directly as well. The results suggest that T. caespitum with an advanced social structure uses the brain to navigate by the light.
