Control and eradicate an insect pest today, without using chemical methods, which damage the environment, people and cultures, it is possible. Thanks to research conducted for years on the control of insects by pheromones.
With the use of pheromones, the use of chemical insecticides are diminished, generating less pollution to the environment, being biodegradable products produced by nature itself and used in very small amounts. Pheromones are species-specific and thus control the plague of these insects, avoiding kill others that may be beneficial and favoring the natural biological balance.
Insect control using pheromone traps.
In the control of insect pests they are mainly used two methods, mass trapper used pheromone to attract males where they are trapped and the second, a novel method of confusion studied at the Institute of Chemical and Environmental Research of Barcelona.
When the identity and chemical structure of the pheromone of a pest is known specified, it can be synthesized in the laboratory and placed in traps to attract males in the plantations, where they will be trapped declining population and damage to crops.
Best suited for the perfect use of the traps is to understand the life cycles of each pest insect, when active as an adult in each generation as the temperature varies in the area where it operates. We recommend using traps when launching the first generation. The traps are designed according to the type of insect that target, its size, behavior and activity. It is also desirable to control the installation location of these traps, as it influences the capture of insects.
Sometimes the pheromone traps are used to find the larval stage of the insect.
In the method of confusion a change in strategy is done, the new compounds inhibit enzymes that degrade the pheromone, where males can not determine or locate where the emission takes place, confusing excess male pheromones and not producing well fertilization of the species. It is a form of progressive and ecological struggle, not exterminating the plague at once, but gradually and without toxic risks from chemical insecticides.
