Abstract  [Aim]  To determine the relative effectiveness of different sex pheromone products for disrupting the mating of Grapholitha molesta (Busck) in a pear orchard. [Methods]  Four brands of mating disruption products; You’er, Ninglu Shengtai, Shenglv Zhibao and Aofumu, were tested in a pear orchard in Laiyang City in July, 2020. Pheromone dispensers were hung in pear trees at a density of 40 per 667 m² and 2 kinds of traps were operated during the same period. In addition, the ratio of damaged fruit and shoots were calculated as an indicator of effectiveness of control. [Results]  There were no significant differences among the 4 brands of mating disruption products tested; all were more than 80% effective and achieved fruit and shoot damage ratios of< 2% and 3%, respectively. [Conclusion]  There are no significant difference between the 4 brands of mating disruption products tested. All four products should therefore be effective for disrupting the mating of G. molesta damage in pear orchards.
