Abstract: Sex pheromone is a species -specific behavior -modifying chemical between female and male, and has been a wide application through five decades of pheromone research. The most widespread and successful applications of sex pheromones concern their use in population monitoring and mass annihilation. The estimated annual production of lures for monitoring and mass trapping is on the order of tens of millions, covering at least 10 million hectares. Here, we review the most important and widespread practical applications in recent years, especially in different insect species. Current problems and derelopment trend were also discussed.
