When the original king and queen of termites die, they are replaced by
the king and queen of another colony
some adult reproductives from the same colony
some adult workers which are specially fed to breed
developing nymphs nurtured as secondary reproductives

When the queen dies, production of the blocking pheromone stops, and secondary reproductives may be produced.
In the Reticulitermes species, the queen and king may be replaced by numerous secondary reproductives, and the colony may become very large with the added productivity of many queens.
