SUMMARY:

The emergence and maintenance of eusociality in insects is a question that has been intrigued scientists for a long time. Why and how does an individual give up its reproductive success to help in the reproductive success of others? In the last years, a series of studies have been shown that the response to the emergence and maintenance of eusociality in the insects is related to the benefits of living in groups, such as an increase in defense, foraging and survival in situations of stress (starvation, pathogen infection or even insecticide poisoning). Although several studies have been demonstrated the benefits of group living, such studies are carried out only with workers, without taking into account the possible role of soldiers (i.e. social context). Therefore, in the present study, we evaluate the effect of social facilitation (i.e. group size) and social context (i.e. presence of soldiers) on the exposure of sublethal doses of the insecticide imidacloprid in Nasutitermes corniger (Motschulsky) (Termitidae: Nasutitermitinae). In general, results showed that the survival of termite groups increases linearly with the size of the group and that the presence of soldiers increases survival in groups exposed to the insecticide compared to groups without soldiers. Thus, the present study shows the importance of N. corniger soldiers in the insecticide tolerance, contributing to new perspectives in the control of this group and adding a new function of this caste in termites.
