高度社会性的昆虫工作者表现出与年龄相关的劳动分工。成虫开始在巢内工作，移动到巢的外围，然后去觅食。通过这个任务序列与蜜蜂(Apis)和蚂蚁(Camponotus)工蚁蘑菇体(MB)的神经解剖学变化有关。我们询问群居黄蜂工蜂(Polybia Aequatoriaris)在成年神经解剖学上是否表现出类似的变化。黄蜂被识别为在巢内工作、在巢内工作或觅食。用体视学方法对工人MB内源性神经元(Kenyon细胞)和含有Kenyon细胞树突的神经毛(花冠)的体细胞体积进行了估计。巢内工蜂的花萼与Kenyon细胞体积比显著小于在巢工蚁和觅食工蚁。在Polybia工作者中，年龄相关的任务专业化与蘑菇体中的主要神经解剖学重组有关。
Highly eusocial insect workers exhibit age-related division of labor. Adults begin working inside the nest, moving to the nest periphery and later to foraging. Passage through this task sequence is associated with neuroanatomical changes in the mushroom bodies (MB) of honey bee (Apis) and ant (Camponotus) workers. We asked whether eusocial wasp workers (Polybia aequatorialis) exhibit similar changes in adult neuroanatomy. Wasps were identified as working in-nest, on-nest, or foraging. The volumes of the somata of workers’ MB intrinsic neurons (Kenyon cells), and of the neuropils containing the Kenyon cell dendritic arbors (calyces), were estimated using stereological methods. In-nest workers had significantly smaller calyx to Kenyon cell volume ratios than on-nest and foraging workers. Age-related task specializations in Polybia workers are associated with major neuroanatomical reorganization in the mushroom bodies.
