Pheromones are chemicals emitted and secreted by an individual and received by another individual of the same species, in which they induce a species specific reaction. By far the greatest variety of pheromone-mediated systems occurs among insects. Sex pheromones chemicals, or blends of chemicals, emitted by an individual of one sex for the purpose of inducing sexual behaviors by members of the opposite sex are the only pheromone mediated system in common usage by members of all insect orders. This undoubtedly stems from the universal need to reproduce and the development of chemosensory organs early in the evolutionary history of Hexapoda, perhaps even before the development of light-sensitive organs.

The problem with [pheromone] companies is not specific to them. Within the scientific community, pheromones are broadly defined as chemical signals released by an animal that induce specific effects on other members of the same species. Although these substances are typically associated with sexual attraction, researchers have found they can have a broader range of influence, such as prompting aggression or modifying parental behaviors.
