Different Type of Pheromones
Pheromones are chemical substances that are manufactured and released by mammals, insects and other living things. These substances tend to trigger specific reactions, including physical and sexual attraction. The role of the pheromone in the mating cycle of many different types of species indicates that the exact effect will sometimes trigger attraction but can also lead to aggressive behavior.
Sex Pheromones The first thing that many people think of when discussing pheromones is sexual attraction. In both humans and other types of mammals, males and females excrete pheromone chemicals that in turn attract the opposite sex. This natural chemical reaction paves the way for triggering sexual excitement that will often lead to mating. More of this is explained at http://pheromones-experts.com/.
For humans, the release of this type of pheromone is ongoing. In mammals and other species that experience specific mating cycles, the pheromones are manufactured and released only at certain times. This type of chemical excretion is essential for the propagation of different species, including humans. One of the most popular pheromones is Pherazone which can be found at: http://ultimatepheromones.com/mens-pherazone.html
Territorial Pheromones Another example of pheromone excretion has to do with establishing the boundaries of what is considered the domain of a specific creature. The general idea is to signal all other creatures that the territory involved is already taken. In the event that another creature wishes to occupy the territory, the excretion serves to signal a need to fight.
One of the best examples of this type of activity is a dog marking a post or tree by urinating at the base. Territorial pheromones are carried in the urine. Other dogs can smell the urine and identify the marking with another animal. In order to claim the territory, the animal will also urinate on the spot, eradicating the previous claim.
Trail Pheromones This type of chemical secretion is common in a number of species, including insects. The purpose is to provide a means of getting back to a previous location. A guidance system of this type can help maintain colonies and aid members of those colonies to forage for food and return it without fail. A good example of this type of activity is found with ants. The ants will search for food and then return it to the colony for the good of the entire group.
Alarm Pheromones There are also pheromones that are excreted when an organism feels threatened in some manner. This is essential in the animal kingdom, since it serves as the trigger for the flight or fight response. The excretions also help to provide some idea of what is about to happen between two antagonists. Depending on the circumstances, both organisms involved will instinctively understand that a fight is about to occur. In some cases, the release of the pheromones may be enough to convince the aggressor that the other party is not going to back down and that flight is the most practical response.
Aggregation Pheromones This type of classification has to do with excretions that trigger some sort of response in both genders. For example, the release of the pheromone may result in attracting the attention of both genders rather than simply the opposite gender. Depending on the impact of the individual pheromones this could lead to some sort of conflict or it could pave the way for some type of mating ritual. Considered the widest classification for pheromones, this category is used for any chemical secretions that don’t seem to fit neatly in other classes.
