What percentage of bees may consider a threat according to the alarm pheromone signal?

The correct response indicates that around 10% of bees in a colony may perceive a threat triggered by the alarm pheromone signal. When bees detect potential danger, typically from a predator or disturbance, they release alarm pheromones that elicit a defensive response from their fellow bees. This pheromone is primarily used to alert others to the threat and coordinate their defensive behavior.

In a given colony, it isn't necessary for the entire bee population to engage in a defensive response; instead, a smaller proportion, like 10%, is sufficient to defend the hive effectively. This percentage represents the innate behavior of bees to conserve energy and resources. Mobilizing the entire colony in every instance of perceived threat could be inefficient and detrimental to the hive's overall functioning, as it may leave the hive vulnerable to other dangers while all bees are focused on one perceived threat.

Recognizing the role of alarm pheromones is crucial for understanding how bees communicate and manage threats within their environment. This knowledge can promote better practices in beekeeping and hive management, focusing on minimizing stressors that may trigger such responses.
