For alerting the group from threat, for sexual attraction etc. but there are other uses of pheromones which are discovered by our scientists. These pheromones can be effectively used for the control of pests in the fields.
In 1995, in United Stated, a group of insects known as Beet army-worms caused a multi million dollars loss in Texas alone by seriously affecting the cotton growing area. But in 1997, researchers could avoid it by disrupting mating procedure between male and female Beet army-worms by flooding 35-acre cotton field with sex attractant pheromones.
With such a pervasion of female scent, the males could not find the females for more than hundred days, and gradually the pest rate reduced. In such a way, certain pheromone traps have also been engineered and are commonly used by farmers and also the home owners. For example Indian Meal Moths (pantry Moths) are attracted to a pheromone in a small box which is actually a sticky substance, and are thus captured for disposal.
By the usage of these pheromones for controlling the pest, we are not only protecting the plant from the pest attack but […]

The use of pheromones is well known in agriculture to keep some insects away from plants. The so-called pheromonal communication is very strong in this Order. Social life and species recognition are triggered by the emission of the right pheromones. That is why the term of pheromone (from Greek “pheros” meaning far and “horman” meaning to excite) was used, because emitted in a very small amount, pheromones launch from a distance a precise behavior in the animals of the same species.
In mammals, pheromones have been supposed for a long time to be very active in sexual communication but the difficulty has always been to isolate the effective molecule. Starting with the same ideas as in insects, it could seem impossible to identify in the huge amount of secreted products, the significant part. Pheromones are often monomolecular in insects, but complex in mammals. A new track was found by chromatography analysis allowing isolation of some simple and consistently present elements that, put together in specific proportions, could reproduce the same effect as the natural pheromone. This new method has […]
