We have investigated escape behaviour of workers of two bumblebee species, Bombus terrestris and B. pascuorum, when confined to test tubes plugged with soil and either exposed to sunlight or kept in darkness. In both these situations B. terrestris performed better (i.e. escaped after a shorter time) than B. pascuorum. B. terrestris (but not B. pascuorum) also performed better in darkness than in tubes exposed to sunlight. This implies that in both situations B. terrestris showed higher readiness to dig than B. pascuorum, and that in tubes exposed to sunlight only B. terrestris showed high readiness to display photopositive behaviour as well. B. pascuorum displayed, however, photopositive behaviour in another escape situation: when released in a dark room in front of a vertical array of four sources of white light. In that situation, B. pascuorum also displayed the tendency to fly upwards, based most probably on responses to gravitational cues.
我们研究了两种熊蜂，即 terrestris 熊蜂和 pascuorum 熊蜂的工蜂在被限制于用土壤堵塞的试管中时的逃脱行为，这些试管要么暴露在阳光下，要么置于黑暗中。在这两种情况下，terrestris 熊蜂的表现都比 pascuorum 熊蜂更好（即逃脱所需时间更短）。terrestris 熊蜂（但 pascuorum 熊蜂并非如此）在黑暗中的表现也比暴露在阳光下的试管中的表现更好。这意味着在这两种情况下，terrestris 熊蜂比 pascuorum 熊蜂表现出更高的挖掘意愿，并且在仅暴露于阳光下的试管中，只有 terrestris 熊蜂表现出很高的展示趋光行为的意愿。然而，pascuorum 熊蜂在另一种逃脱情况下表现出趋光行为：当在一个黑暗的房间里，在垂直排列的四个白色光源前被释放时。在那种情况下，pascuorum 熊蜂也表现出向上飞行的趋势，这很可能是基于对重力线索的反应。
