本研究描述和量化的行为行为的两个实验室殖民地的Acromyrmex subjuveneus brunneus通过调查工人年龄polyethism。在19周的观察期内记录了29种行为。年轻人执行任务巢内有关的育雏护理和护理的真菌花园，而老年人执行活动巢外，如觅食和活动的废物室。大型、中型和小型工作者的平均寿命（+/- SD）分别为108.21 +/- 3.30、109.15 +/- 1.92和122.71 +/- 1.55天。小型工人比大型和中型工人更有可能进入老年。本研究从年龄、身体和时间亚种性的关系以及多民族性的角度来描述任务转换。
This study describes and quantifies the behavioural acts of two laboratory colonies of Acromyrmex subterraneus brunneus by investigating worker age polyethism. Twenty-nine behavioural acts were recorded during the 19-week observation period. Young individuals performed tasks inside the nest related to brood care and care for the fungus garden, whereas older individuals performed activities outside the nest such as foraging and activities in the waste chamber. The average longevity (+/- SD) was 108.21 +/- 3.30, 109.15 +/- 1.92 and 122.71 +/- 1.55 days for large, medium and small workers, respectively. The small-sized workers presented a higher probability of reaching older age than large- and medium-sized workers. This study describes task switching according to age polyethism and the relationship of physical and temporal subcastes.
