[The behavioral strategy of ants with a change in the level of food motivation].
Learning of ants was studied in a symmetrical multi-choice maze at different levels of food "social" motivation. A capability was shown of scout ants Myrmica rubra for changing rapidly behavioral strategy when the motivation level of a family changed from the low one for the high or vice versa. In the satiated state the ants demonstrated a clear-cut research activity. This activity was associated with high variability and instability of the maze habit. In the "hungry" state movement trajectories were rapidly minimized, the majority of ants used one dominant scheme of moving. Initial level of motivation determined the peculiarities of and learning and ability to transform behavioral strategies.
