Alarm pheromone

An alarm pheromone is a chemical signal released by an insect or animal to alert others nearby of danger or a threat. When released, it quickly triggers a response from others, such as increased alertness, defensive behavior, or fleeing. For example, certain ants release alarm pheromones to warn colony members of a predator or disturbance, prompting them to attack or evacuate. These signals are crucial for communication within social groups, helping them coordinate responses to protect the colony or community efficiently.
