- Аннотация: In red wood ants the functional organization of a colony is based on deep «professional» specialization of individuals. Here we investigate distinguishing behavioral features in scouts and foragers by means of a purposefully designed battery of tests. To reveal scouts and foragers the experimental paradigm of «binary tree» was used. Scouts appeared to be an invariable group characterised by a high level of exploratory activity and high frequency of switching between different behaviours. They share with honey-dew collectors certain specific features of exploratory behaviour. Foragers share with hunters such characteristics as high agility and relatively low level of exploratory activity. With respect to their level of aggressiveness, which they display in the test «meeting with an enemy», scouts and foragers can be placed between peaceful honey dew collectors and aggressive hunters and guards. The distinguishing features of scouts are their predominantly exploratory reactions towards the enemy, the absence of the «death grip» reaction which is characteristic for guards and hunters, and relatively high frequency of the reaction of avoidance, which is absent in the repertoire of hunters and guards. Preliminary results of the test «search for the exit in the maze» enable us to suggest that scouts remember their way better and keep memory longer than foragers. Ants possess stable sets of behavioural features than can be considered a «behavioural syndrome».
