Pheromones used in reproduction are not likely to be found in organisms that only reproduce asexually.
The chemicals called pheromones are used to communicate between members of the same species and cause the recipient to react physically or behaviorally. Pheromones are a subset of organisms' larger class of chemicals to communicate, known as semiochemicals, from the Greek <em>semeon</em>, meaning signal or mark.
Animals communicate chemically constantly, with pheromones mediating more interactions than any other type of signal. The majority of pheromone research has been conducted on insects, particularly species that are considered pests.
For these, using pheromones that alter their behaviour in various ways might be employed for population control, pest management, or monitoring.
