Migration ant Eciton

Eciton is one genus of ants (Family Formicidae, subfamily Ecitoninae) commonly known as Ant Army (Army Ants). Experts life of ants attracted to recite this because this ant is one of a group of ants that are expansive in the other organisms and colonies have organized very well. In addition, the ant is famous for its uniqueness in the migration, ie forming a "nest" for the queen and her eggs are made from their own bodies (called Bivouac) during the trip. Let us follow the following description.

Eciton burchelli and E. hamate are two examples of army ants of the most widely studied. Ants underwent two phases of life, namely the phase remain in one place (statary) and mobile phase (nomadic).

Dynamics of colony

Statary phase occurs when the queen is laying eggs. Previously, the worker ants will stop and the building also provides an opportunity bivouac.Fase worker ants to care for advanced instar larvae. Then, start-up instar larvae stop eating and then spin cocoons. Statary phase lasted for 20 days in E. hamate and 21 days in E. burchelli.

Nomadic phase starts when a young worker ants emerge from the cocoon, and began to make movements that trigger Bivouac ants workers to unload and prepare for the trip. Nomadic phase lasts for 16 to 17 days in E. hamate, and 12 to 15 days in E. bruchelli.

So, statary and nomadic phase triggered by the emergence of the cocoon and new workers (young). When phase statary arrived, then the queen will also produce eggs.

Eciton ants have many forms of worker caste individuals (polymorphic) in size between 3-12 mm. In general, small-sized worker ants called a minor worker, and a great worker called major. Small worker ants usually acts as a "worker" in charge of caring for a true queen, eggs and larvae. This little ant is also in charge of feeding the major workers 'difficulties' to eat because of the large mandibulanya like sickles. Large-sized ants that is the "warrior".

Eciton ant colonies can grow very quickly, because the queen ant can lay as many as 55,000 to 66,000 eggs per week during phase statary. However, in the middle of this phase, a queen is able to produce eggs as many as 100,000 to 300,000 eggs. A considerable amount!

Wandering behavior Eciton

When entering the phase of nomadic (wandering), ant Eciton cooperation among residents showed a remarkable colony of neat. Please note, that the number of individuals in a colony of Eciton ranged from 150,000 to 700,000 workers combined with a tail of the queen.

During the wandering, larvae were taken and cared for by worker ants with caution, as well as the queen ant. Minor worker ants will tie its legs together to form a structure that protects the larvae and the queen ant, other than as a "living bridge" for them.

Eciton ants wandering speed is not high. They only travel about 100 to 200 meters per day. Nevertheless, the damage inflicted on other organisms is quite obvious.

Eciton influence on other organisms

Experts note some of the losses suffered by the organism as a result of wandering ants Eciton, for example in Polistes wasps and bees Bombus. This is presumably a mechanism of population control wasps and bees are very effective by ants Eciton.
