primer pheromone

Primer pheromones are chemical signals secreted by an organism that influence the physiology of another member of the same species, leading to behavioral changes over time. Unlike releaser pheromones, which cause immediate behavioral responses, primer pheromones affect internal processes.1

These pheromones are crucial in coordinating reproductive physiology, particularly in mammals, where compounds in urine can influence ovulation and hormone release. In social insects like honeybees, primer pheromones secreted by the queen regulate worker behavior and prevent the development of new queens. They can also synchronize physiological processes, such as sexual maturation in locusts. The effectiveness of primer pheromones depends on their chemical properties and how they are perceived, sometimes through direct contact or via the olfactory system.1
