Gene activity in defenders depends on invading slavemaking ants

Temnothorax americanus is a slavemaking ant found in northeastern America. These tiny social insects neither rear their offspring nor search for food themselves. Instead, they raid nests of another ant species, Temnothorax longispinosus, kidnap their larvae and pupae to bring these back to their own nest. Once these have reached adulthood, the abducted ants must feed the brood of the slavemaking species, search for food, feed the slavemakers, and even defend their nest. A colony of slavemakers, consisting of a queen and two to five workers, can keep 30 to 60 slaves.
