Summary
Chemical signals synchronise mating, such as moth sex attractants.
In depth
Moth bombykol, boar androstenone, mouse pheromones that accelerate puberty (Vandenbergh effect), and the vomeronasal organ in many mammals. Human pheromones are not established.
Pheromones synchronise reproduction, attract mates and mark territory. Used in pest control by mating disruption.
Example: gypsy moth traps use synthetic pheromone.
Pheromones are chemicals released by one individual that change the behaviour or physiology of another of the same species. In reproduction, they attract mates over long distances, signal readiness, synchronise breeding and sometimes block competitors.
Female silk moths release bombykol, which male antennae detect at a few molecules, allowing them to find her from kilometres away; Adolf Butenandt isolated it in 1959. Mice have pheromones that accelerate puberty (Vandenbergh effect) and can block pregnancy in newly mated females (Bruce effect); the pig pheromone androstenone triggers the sow's mating stance. Evidence in humans is debated. Pheromone traps are used in pest control.
Example: queen bee substance suppresses workers' ovaries.
