Hormone-like substances (also exohormones, telergons) that, in the form of fragrances or attractants, in contrast to hormones, do not work in the body, but are released to the outside. The name derives from the Greek words ferein = transferred and hormãn = to drive or stimulate. In humans, they play an important role in the reproductive drive, such as androstenone (sweaty smell of the male armpit), copulins (vaginal secretions) and trimethylamine (fish brine). Some of these sexually animating "fragrance attractants" only work for women, others only for men.
In insects, pheromones trigger certain actions or social functions. For example, queen bees release certain pheromones to the working bees, which prevent them from breeding new queens. If the queen fails and the pheromone delivery fails, the rearing of a successor or new queen is automatically started. In the vineyard, synthetically produced sexual pheromones are used in the so-called disrupter (Mating disorder, sexual confusion) for the environmentally friendly control of animal pests within the scope of the Biological crop protection used. Among other things, these are the dreaded in viticulture grape (or their caterpillars) that are prevented from mating.
