时间上的劳动分工，即年龄多型性，其中利他的品级个体随着年龄增长而改变其任务，在蜜蜂和蚂蚁（膜翅目）以及其他社会性昆虫中广泛存在。在此我们报道在一种社会性蚜虫（半翅目）中发现了精细的年龄多型性。角倍蚜是一种形成虫瘿的蚜虫，其中单态的一龄若虫在二龄蜕皮时分化为正常若虫和兵蚜。兵蚜既不生长也不繁殖，而是进行虫瘿清理和群体防御。利用人工饲料饲养系统，我们收集了按年龄划分的兵蚜群体，并监测它们的社会行为。我们观察到年轻的兵蚜倾向于清理，而年老的兵蚜则优先攻击，从而验证了从家政到防御的年龄相关任务转换。对自然虫瘿中的兵蚜进行策略性取样、年龄估计和行为观察发现：（1）年轻的清理兵蚜倾向于栖息在虫瘿上部与成虫在一起的区域；（2）年老的攻击兵蚜倾向于分布在虫瘿下部区域，特别是在虫瘿开口周围；（3）虫瘿结构以一种适应性的方式与兵蚜的巢内移动、衰老和任务转换相关联。这些结果凸显了一种进化上的平行性，可与在蜜蜂群体中观察到的复杂的时间劳动分工相媲美。
Temporal division of labor, or age polyethism, in which altruistic caste individuals change their tasks with aging, is widely found in bees and ants (Hymenoptera) and also in other social insects. Here we report the discovery of elaborate age polyethism in a social aphid (Hemiptera). Tuberaphis styraci is a gall-forming aphid in which monomorphic first instar nymphs differentiate into normal nymphs and soldiers upon second instar molt. Soldiers neither grow nor reproduce but perform gall cleaning and colony defense. Using an artificial diet rearing system, we collected age-defined groups of soldiers and monitored their social behaviors. We observed that young soldiers tend to clean whereas old soldiers preferentially attack, thereby verifying age-dependent task switching from housekeeping to defense. Strategic sampling, age estimation and behavioral observation of soldiers from natural galls revealed that (1) young cleaning soldiers tend to inhabit upper gall regions with adult insects, (2) old attacking soldiers tend to be distributed in lower gall regions, particularly around the gall openings, and (3) the gall structure is linked to intra-nest movement, aging and task switching of soldiers in an adaptive manner. These results highlight an evolutionary parallelism comparable to the sophisticated temporal division of labor observed in honeybee colonies.
