Abstract

Nests of eusocial bees may be invaded by social parasites that leave their own colonies when there are no direct reproductive options, they seek for reproductive opportunities in conspecific colonies. Thus, unrelated individuals are exploited and carry the costs of this strategy, because they provide food resources and rear for the offspring they are not related to them. The overall purpose of this project is to investigate whether the reproductive workers of Scaptotrigona depilis leave their nests, invade non-natal conspecific nests and lay eggs that will give rise to males. If the reproductive workers do invade non-natal nests (in queenright or queenless conditions), do they tend to enter non-natal queenright or non-natal queenless colonies? We believe that our results will contribute significantly to the studies focusing on reproductive strategies in social insects. (AU)
