The sustained release pheromone formulation

PROBLEM TO BE SOLVED: To provide a sustained release pheromone formulation capable of providing high pheromone release amount through a controlling period in pest having an aliphatic hydrocarbon compound having the melting point to be solid at normal temperature and 20 to 35 carbon atoms as a pheromone material.SOLUTION: There is provided a sustained release pheromone formulation which contains at least a film of an ethylene-vinyl acetate copolymer and an aliphatic hydrocarbon compound carried by the film and capable of penetrating the film and having the melting point to be solid at normal temperature and 20 to 35 carbon atoms and targets pest having the aliphatic hydrocarbon compound as a pheromone material.SELECTED DRAWING: None
