Abstract：
The sex pheromone communication system is critical to reproduction in the Lepidoptera. Research on the identification of lepidopteran sex pheromones is therefore important for monitoring and controlling lepidopteran pests. The diversity of sex pheromones is reflected in the complex chemical structure and composition of their components, which are divided into Type 0, Type Ⅰ, Type Ⅱand Type Ⅲ, according to their chemical structure. In general, the sex pheromones of a species belong to only one of these types. However, recent studies have shown that an increasing number of species have sex pheromones of more than one type (hybrid pheromone system). This paper concentrates on such species, mainly focusing on the composition, distribution, identification and behavioral functions of their sex pheromones.
