Pheromone : Study
India scientists developed sustainable pheromone dispenser with a controlled release rate which could bring down costs of pest control and management.
- Pheromones are chemical substances which are secreted on the outside by an individual, and received by another individual of the same species.
- These are present in all bodily secretions, and especially in the axillary sweat — can be detected by the olfactory system.
- Pheromones are ecto-hormones, meaning they are secreted outside the body.
- Types of Pheromones
- Releaser pheromones: They work right away and elicit a specific response from the other person.
- Signaler pheromones: They give information about the person who releases them. For example, they help a mother tell her own baby apart from other babies.
- Modulator pheromones: They affect mood and emotions.
- Primer pheromones affect hormones, for example during pregnancy or menstrual cycles.
- Animals, with their heightened senses and vomeronasal organ are known to secrete pheromones to trigger many kinds of behaviours like raising an alarm, signalling a food trail, warning another animal to back off, and bonding with an offspring.
- 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.
