WHAT ARE THE PHEROMONES AND ITS METHODS OF ACTION.

   Pheromones are substances produced by fragrant animals or any set of living things, are released and dispersed through the air and affect the behavior of other animals of its own species, with a very old communications. The way the pheromone is similar to that used hormones within the body. They carry messages from a specific chemical certain other cells and cause to be carried out certain actions. There are different classifications of pheromones, sexual deterrent, track, alarm, etc. Pheromones used for pest control are the sex, the females emerge to reclaim the male for mating.

    The insects are animals that regularly use pheromones for this purpose by issuing a sex pheromone specific to each species. The males fly up to find the smell appropriate for them to identify their females. At present, it is made with pheromone traps used to capture harmful insects. With the sex pheromones of other undesirable insects were spray infected areas to confuse the males seeking females of other species.

The traps with pheromone are in use for attracting the males.

     The insects live in groups like ants use different pheromones to indicate where is the food, that there are enemies lurking or that we must flee. Besides have other pheromones by which to identify their larvae in the dark of the anthill, some invertebrates have copied the code, as the bug killer who leaves traces of false odor and eats ants that follow. Wide variety of beetles, spiders, centipede or parasites produce pheromones of ant larvae getting fed and living in their midst without fear of being discovered.

Many insects indicate different situations using pheromone.

     In mammals are also common pheromones, which marked its limits territories, females attract males for mating, detect intruders on their territory by pheromones that release and identify other individuals of the species included recognize the who are closest in neighbourliness. Recent discoveries have shown that pheromones of primates also play an important role. Humans to the arrival of puberty acquired a certain smell of sweat, this suggests that people's behavior can be changed by certain pheromones.

     This not only happens to animals, there are some tropical orchids that produce sex hormones of some wasps, males try to mate with flowers that identify females of their species and thus carry pollen from one to another orchid.
