Western honey bee
Pheromones

Pheromones (substances involved in chemical communication) are essential to honey bee survival. Western honey bees rely on pheromones for nearly all behaviors, including mating, alarm, defense, orientation, kin and colony recognition, food production and integrating colony activities.

The alarm pheromone has shown to be attractive small hive beetle. Therefore, there is a tradeoff between recruiting guards bees to defend the invaders and attract more beetles. Small hive beetle has a lower sensing threshold for the honeybee pheromone, which exacerbates the damage to honeybee hive.
