Definizione

A chemical substance that is usually produced by an animal and serves especially as a stimulus to other individuals of the same species for one or more behavioral responses. 1

Nota

Any endogenous chemical secreted in minute amounts by an organism in order to elicit a particular reaction from another organism of the same species. Pheromones are widespread among insects and vertebrates; they are also found in crustaceans but are unknown among birds. The chemicals may be secreted by special glands or incorporated in other substances, such as urine. They may be shed freely into the environment or deposited in carefully chosen locations. Pheromones are also used by some fungi, slime molds, and algae as attractants in reproduction; organisms of complementary reproductive cell types grow or move toward each other. 2

Contesto

In 2001, a faster, more effective method to monitor VMB [vine mealybug] was developed, based on a sex pheromone that female VMBs use to attract winged adult males. 3
