Many mammals, for example: dogs and cats, deposit chemicals in and/or around their "territory". As these vaporize, they signal to other members of the species of the presence of the occupant of the territory.

Definition: Pheromone is a chemical secreted externally by an organism to send information to members of the same species.

Releaser pheromones can produce specific behavior patterns, such as sexual attraction, avoidance, etc. In many lower animals, small amounts of releaser pheromones are sufficient to cause the animal to behave in a certain way. The first pheromone, which was discovered in 1956, was a sex attractant releaser pheromone for silkworm moths which causes male moths to beat their wings rapidly in a mating "flutter dance". This eliciting of specific behavior has not been demonstrated in more complex animals like humans.

Releaser pheromones initiate immediatebehavioral responses in insects upon reception. There are three types of chemically identified releaserpheromones: ones that cause sexualattraction, ones that alarm behavior, and ones that allow recruitment. Sex pheromonesrelease the entire repertoire of sexual behavior. Thus a maleinsect may be attracted to and attempt to copulate with an inanimate object that has sex pheromone on it. It appears that most insectsare rather sensitive and selective for the sex pheromone oftheir species. Insects show far less sensitivity and chemospecificityfor alarm pheromones. Alarm selectivity is based more on volatility than on unique structural features. Recruiting pheromones areused primarily in marking trails to food sources. Terrestrialinsects lay continuous odor trails, whereas bees and other airborne insects apply the substances at discrete intervals.
