Chemicals released by animals and humans that trigger physiological or behavioral reactions in other members of the same species. Pheromones do not elicit detectable smells but are processed in a similar manner to olfactory stimuli, by specialized receptors in the nasal cavity called vomeronasal organs. go to glossary index
chemical messengers related to the sense of smell, and in some cases sexuality
Chemicals emitted by an organism to influence the behavior of other organisms of the same species.
Special chemicals secreted by many animals that trigger particular reactions in members of the same species. Humans seem to have a pheromone that regulates the timing of menstruation in females.
Chemicals released, usually in minute amounts, by one animal, that are detected by, and act as a signal to other members of the same species.
Chemical secretions that elicit a specific behavioral response (often attraction) in another individual of the same species.
chemical secretions from an animal to attract another, or display territory boundaries.
Natural chemicals or hormones that elicit a sexual response. Many perfumes and colognes add pheromones to aid in the attraction of a mate.
In many, perhaps most species, including humans, the smells that are produced by the skin or other organ to attract others of the same species.
a class or hormone, or chemical messenger, produced by an organism and detected by another member of the same species; pheromones are used for communication between conspecifics.
chemical substances secreted from glands and used as a means of communication. Honey bees secrete many different pheromones.
FER-eh-moanz Biochemicals an organism secretes that elicit a response in another member of the species. 660
Chemicals secreted by animals that attracts members of the opposite sex.
Chemical signals that travel between organisms rather than between cells within an organism; serve as a form of communication between animals.
are chemical substances which make communication possible between living beings. They are mainly significant as a medium which insects use for sexual attraction. Most pheromones are odorless to human beings.
chemical substances secreted by an animal that elicit a specific behavioral or physiological response in another animal of the same species.
chemicals that help externally to regulate an animal's environment by influencing other animals of the same species
chemicals released into air or water that are detected by and responded to by other animals of the same species
are those molecules secreted by an organism that evoke a response in individuals of the same species. Not all pheromones attract potential mates. On the one hand, aggregation pheromones summon conspecific predators to a meal of palatable insects. But in the perpetual war between the eaters and the eaten, there are chemical messengers that act as double agents. (E)-¤-Farnesene may induce other aphids to flee, but, at the same time, it is believed to point the wasp Aphidius uzbekistanicus to the aphids' whereabouts. To the aphid, this semiochemical is an alarm bell; to the female Aphidius wasp, looking for a suitable host in which to deposit her eggs, it is a dinner bell.
odorous chemicals secreted by an animal that affect the behavior of other animals. (180)
Chemical substances produced by animals that attract and stimulate sexual partners of the same species.
A chemical secreted by an animal that influences the behavior or development of others of the same species, often functioning as an attractant of the opposite sex.
Chemical substances that are secreted outside the body. These substances help with fertility communication between two animals.
Natural chemicals or hormones that induce a sexual response.
Special chemicals secreted by many animals that float through the air to attract other members of the same species. They represent a primitive form of communication.
