PROBLEM TO BE SOLVED: To provide a sustained release preparation of sex pheromones enabling controlled simultaneous release of sex pheromones corresponding to developmental periods of two or more of insect pests, and a method for controlling the pests. SOLUTION: The sustained release preparation for sex pheromones contains at least two sex pheromone substances comprising 10-20C aliphatic derivatives and is provided with a first chamber of a polymer material containing a part or total of sex pheromone substances having minimal carbon number excluding carbon number of functional groups among the aliphatic derivatives and a second chamber of a polymer material containing the remaining sex pheromone substances. There is further provided a controlling method to use the sustained release preparation of sex pheromones. COPYRIGHT: (C)2011,JPO&INPIT
