A chemical secreted by an animal, especially an insect, that influences the behavior or physiology of others of the same species, as by attracting members of the opposite sex or marking the route to a food source.

pheromone

[fer′əmōn′]
Etymology: Gk, pherein, to carry, hormaein, to stimulate
a substance secreted by an organism that elicits a particular response from another individual of the same species, usually of the opposite sex. Pheromones may be sexual stimulants or attractants or alarm or trail-making substances; in social insects they have a role in the determination of castes.

pheromone

A secreted or excreted chemical factor that triggers a social response in members of the same species, which fall into one of three broad categories:  alarm pheromones, food trail pheromones, and sex pheromones.

pheromone

An odorous body secretion that affects the behaviour of other individuals of the same species, acting as a sex attractant or in other ways. Pheromones are important in many animal species but, until recently, were thought to be unimportant in humans. It has now been shown, however, that the timing of ovulation in women can be controlled by pheromones from the armpit. This is believed to be the explanation of the fact that women living together will frequently develop synchronized menstrual cycles.

pheromone

a chemical substance used in communication between organisms of the same species. Pheromones are found mainly in animals, but they occur in some lower plant groups where a chemical is secreted into water by female gametes to attract male gametes. In animals, for example, pheromones are transmitted in the air, as in female emperor and eggar moths, which secrete a chemical that is attractive to males over large distances, or by a dog marking out his territory with urine. Insect pheromones have been used to trap females of serious pests.
