Sex Pheromones

Abstract

Pheromones are chemical substances used for communication among individuals of teh same species. Most pheromones are produced by exocrine glands and are released outside the insect body. In many insects, one sex, often the female, produces a pheromone to attract the opposite sex for mating puposes from some distance away. these pheromones are known as sex-pheromones. Sex pheromones are useful in plant insect pest control, patricularly for teh purpose of forecasting the population of insects.
Sex-pheromone of forecasting is usually based on teh extraction of the pheromones from females, the identification of chemical components of teh pheromones, the synthesis of these chemicals and then biological testing of the synthetically produced sex-pheromones in the laboratory and field.
