Description
We studied the organisation of garbage disposal and management in the leafcutting ant Atta cephalotes. The nest of this species has an internal garbage heap to which waste from the fungus garden is taken. The transport of waste from the fungus gardens to the garbage heaps is an example of task partitioning. Ninety-four percent of the garbage loads transferred from the fungus garden to the garbage heap were transferred indirectly via a caching site just outside the garbage heap entrance. A further 3% were transferred directly from a fungus garden worker to a garbage heap worker, again just outside the heap entrance. Only 3% were taken directly to the garbage heap without task partitioning. This is the first described example of task partitioning in insect societies for work other than foraging and the first example of task partitioning occurring entirely within the nest. Furthermore, there is a strong division …
