APPLICATION OF PHEROMONES IN PEST CONTROL1. IntroductionPest management has become an increasingly vital issue in the development of agriculture. Traditional pest control tends to apply pesticides in exposed areas far from where they are needed and to use them much more than necessary. Nowadays, scientists find a chemical substance from insects and apply it to pest control, this kind of chemical substance is called pheromones. What are pheromones? Pheromones are chemical substances emitted by an organism that influence the behavior of the same species. The purpose of this article is to explain the reasons and methods of using pheromones to control pests to improve productivity and simultaneously reduce pesticide use. First, the article will discuss the reasons why pheromones should be used in pest management. Furthermore, it will introduce the application of pheromones. Finally, the document will focus on the advantages and problems that will arise in the procedure of applying pheromones.2. Reasons for Using Pheromones in Pest Control Purpose 2.1 Biological Characteristics of Pheromones According to the definition, pheromones are the class of chemical materials that insects and other organisms release to communicate with other individuals of their own species. This type of biological feature offers scientists opportunities and directions to exploit the specificity of pheromones to effectively manipulate parasite behavior. According to thousands of reliable experiments, scientists consider the application of pheromones as a feasible solution to release the growing public concern about the huge amount of toxic pesticides to control insects.
