What is the primary function of the Masanobu gland in bees?

The Masanobu gland in bees, which is primarily associated with foraging bees, plays a crucial role in communication within the hive. Its main function is to secrete recruitment pheromones, which serve as chemical signals to inform other bees about the location of food sources. When a foraging bee finds a nectar or pollen source, it can return to the hive and use the pheromones produced by the Masanobu gland to attract other foragers. This communication is vital for maximizing resource gathering and ensuring that the colony efficiently exploits available food sources.

This functionality enhances the hive's collective foraging efficiency, providing a clear advantage in resource acquisition compared to solitary foraging behaviors. Understanding this communication system is essential for effective beekeeping, as it highlights the importance of bee social interactions and the role of pheromones in their survival and productivity.
