[Objectives]  To determine which of four commonly used pheromone dispensers has the best pheromone release rate and causes the most mating disruption to Grapholitha molesta. [Methods]  The release rates of G. molesta sex pheromones from PE tubes, PE bottles, PE bags and PVC tubes were measured under field conditions with gas chromatography. Field trials were carried out to determine the efficacy and longevity of control achieved by each of the four types of dispenser. [Results]  The release rate of G. molesta sex pheromone from PE tubes and PE bottles ranged from 0.32 mg/d to 1.62 mg/d and 0.59 mg/d to 2.73 mg/d, respectively, and the effective duration of pheromone release from these dispenser types was up to 5 months. The release rate from PVC tubes was between 0.71 mg/d and 6.86 mg/d within a validity period of three months. Pheromone in PE bags lasted only one month, and its release rate ranged from 1.14 mg/d to 19.27 mg/d. The release of G. molesta sex pheromone from the four dispensers was consistent with the first-order kinetic equation and the half-life of pheromone in the four dispensers can be ranked, from high to low, as follows: PE tube > PE bottle > PVC tube > PE bag. All four types of dispenser achieved > 90% mating disruption. [Conclusion]  PE tubes and PE bottles are the best dispensers of G. molesta pheromone because of their relatively stable release rate and long duration of pheromone release under field conditions.
