What method can influence a queen bee's laying behavior?

Queen caging can significantly influence a queen bee's laying behavior because it temporarily restricts her movement and can create specific conditions that affect her reproductive output. When a queen is caged, she may be isolated from the worker bees, leading to changes in their behavior and possibly affecting the pheromones she produces. These pheromones play a crucial role in signaling her presence and status to the hive, which can directly impact worker behavior related to caring for her and maintaining brood temperature.

Caging a queen can also be used to synchronize the timing of egg-laying or to control her interactions with the colony. For example, it can be employed during periods when a new queen is being introduced or when requeening is necessary, which can further influence dynamics within the hive and overall hive productivity.

The other options, while they can affect the hive environment or overall bee health, do not directly manipulate the queen's laying behavior in the same focused manner as queen caging does.
