A hive of laying workers with no brood is called "hopelessly queenless." Because the workers are not mated (and can't mate), they can lay and raise only unfertilized drone (male) eggs/larvae. Because they cannot lay fertilized (female) eggs, they can't raise new workers nor a new queen.
Eventually all the female bees will age and die, followed shortly thereafter by the younger drones until - dead-out.
