about pheromones

pheromones or
everything you always wanted to know about sex (but were afraid to ask)

a pheromone (from greek phero "to bear" and "hormone") is a chemical that triggers a natural behavioral response in another member of the same species. there are alarm pheromones, food trail pheromones, sex pheromones, and many others that affect behavior or physiology. their use among insects has been particularly well documented, although many vertebrates and plants also communicate using pheromones.

the term "pheromone" was introduced by peter karlson and martin lüscher in 1959, based on the greek pherein (to transport) and hormone (to stimulate). they proposed the term to describe chemical signals from conspecifics which elicit innate behaviours soon after butenandt characterized the first such chemical, bombykol (a chemically well-characterized pheromone released by the female silkworm to attract mates).

in animals, sex pheromones indicate the availability of the female for breeding. male animals may also emit pheromones that convey information about their species and genotype. many insect species release sex pheromones to attract a mate, and many lepidopterans (e.g., moths and butterflies) can detect a potential mate from as far away as 10 kilometers (6 mi). pheromones can be used in gametes to trail the opposite sex's gametes for fertilization. pheromones are also used in the detection of oestrus in sows. boar pheromones are sprayed into the sty, and those sows which exhibit sexual arousal are known to be currently available for breeding.
