Table 1 Discrimination capabilities of two ant species after manipulation of their early experience. Number of agonistic acts and duration (in seconds) of allogrooming behaviours of T. unifasciatus and T. parvulus workers tested during 10 minutes towards a M. ravouxi, C. muellerianus or a homospecific worker. Test workers were reared for 10 days after emergence either in the presence of M. ravouxi (batch A), C. muellerianus (batch B) or nestmate workers (batch C).
