Temporal polyethism in workers of Ectatomma edentatum (Formicidae: Ponerinae)

In the present study, adult ants emerged from five nests kept under laboratory conditions were individually monitored in order to determine their longevity and observe their individual behavior in relation to age (temporal polyethism). Our results showed that most of the tasks related to colony maintenance were executed during the three first age intervals (comprising from 1 to 150 days of age), namely brood care, followed by grooming activities (self and allogrooming), nest maintenance activities (such as floor and nest inspection), and social related activities (antennating and food exchange among adults). Foraging activities were performed by ants in the higher age intervals
