切叶蜜蜂Megachile tsurugensis在先前存在的隧道中建立了一个育苗细胞，用她切成不同大小的叶子圆盘，并将它们组装成俄罗斯Matryoshka玩偶。通过实验操作育苗细胞，研究了她如何调节适合育苗细胞内部体积的叶盘的大小。当通过去除大量叶盘来人为增加内部体积时，她减小了叶盘的大小，尽管增加它会使叶盘更适合增加的内部体积。作为反向操作，当通过将一组预组装的叶盘的内层插入育苗细胞来减小内部体积时，她减小了叶盘的大小，使得叶盘可以适应减少的内部体积。这些结果表明，她至少使用了两种不同的机制来调节视盘的大小：在第一次操作中，分别使用关于建筑工作完成程度的一些内部记忆；在第二次操作中，分别使用建筑工地的尺寸信息的感觉反馈。结论是，耻辱机制，即由构建工作改变的孵化细胞的即时感觉反馈，单独不能解释蜜蜂行为的细节，特别是关于她对第一次操纵的最初反应。为了更完整地解释独居蜜蜂表现出的行为，本文还讨论了两个额外的行为元素，即建筑活动的加强和维度信息的处理，以及污名。
The leaf-cutter bee, Megachile tsurugensis, builds a brood cell in a preexisting tunnel with leaf discs that she cuts in decreasing sizes and assembles them like a Russian matryoshka doll. By experimentally manipulating the brood cell, it was investigated how she regulates the size of leaf discs that fit in the brood cell’s internal volume. When the internal volume was artificially increased by removing a bulk of leaf discs, she decreased the leaf disc size, although increasing it would have made the leaf disc more fitting in the increased internal volume. As a reverse manipulation, when the internal volume was decreased by inserting a group of inner layers of preassembled leaf discs to a brood cell, she decreased the leaf disc size, so that the leaf disc could fit in the decreased internal volume. These results suggest that she uses at least two different mechanisms to regulate the disc size: the use of some internal memory about the degree of building work accomplished in the first and of sensory feedback of dimensional information at the construction site in the second manipulation, respectively. It was concluded that a stigmergic mechanism, an immediate sensory feedback from the brood cell changed by the building work, alone cannot explain the details of the bee’s behavior particularly with respect to her initial response to the first manipulation. For a more complete explanation of the behavior exhibited by the solitary bee, two additional behavioral elements, reinforcement of building activity and processing of dimensional information, were discussed along with stigmergy.
