[Objectives]  Sugar-vinegar-spirit liquid can effectively control Grapholita molesta, especially gravid females, whereas sex pheremone lures could work on males. [Methods]  This paper studied the effects of using sugar-vinegar-spirit liquid to trap G. molesta in pear orchards under a range of different conditions; 3 shapes of trap opening, the presence or absence of a pheromone lure, 4 trap heights, and 5 different trap spacings. [Results]  Optimal trapping was achieved when the ratio of brown sugar∶vinegar∶white spirits∶water was 3∶1∶3∶80, the trap bottle had a rectangular opening, contained a sex pheromone lure, was placed at a height of 1.5 m, and were spaced 4 m apart. [Conclusion]  Effective control of G. molesta can be easily achieved with sugar-vinegar-spirit liquid.
