Abstract  [Objectives]  Reducing pesticide residues and developing effective, environmentally-friendly pest control and prevention methods are important for pear production in our country. [Methods]  Different pest control techniques, including mulching, hanging diffusers and spraying chemical pesticides were tested and compared. Three different treatment areas were established; a comprehensive grass control area, a comprehensive grassless control area and a demonstration area. The effectiveness of different pest control methods was assessed by comparing the number of pests and fruit scabs in each area. [Results]  In 2018, the total annual catch of Grapholita molesta in the comprehensive grass control area and comprehensive grassless control area was 38.8 and 63.2 per trap, respectively, significantly lower than in the conventional control area (1 416.7 per trap). In 2019, the total annual catch of G. molesta in the comprehensive grass control area and comprehensive grassless control area was 14.0 and 15.5 per trap, respectively, significantly lower than in the conventional control area (498.3 per trap). In 2021, the total annual trap catch of G.molesta in the comprehensive grass control area and comprehensive grassless control area was 84.0 and 109.8 per trap, respectively, significantly lower than in the conventional control area (802.6 per trap). In 2018, the peak fruit decay rate of Xinli No. 7 in the conventional control area was 22.80%; significantly higher than that in the comprehensive grass control area (8.33%) or comprehensive grassless control area (10.33%) over the same period. The peak fruit decay rate of Hong Hongxiangsu in the comprehensive grass control area and comprehensive grassless control area were 20.67% and 23.33%, respectively, significantly lower than that in the control area (55.33%). In 2019, the peak fruit decay rate of Xueqing in the comprehensive grass control area and comprehensive grassless control area were 6.00% and 5.83%, respectively, significantly lower than that in the control area during the same period (21.33%). In 2021, the peak fruit decay rate of Xinli No. 7 in the control area was 15.60%; significantly higher than that in the comprehensive grass control area (6.00%) or the comprehensive grassless control area (6.80%). In 2018, 2019 and 2021, the overall use of chemical pesticides in the comprehensive prevention and control areas decreased by 53.81%, 54.50% and 34.00%, respectively, compared to the conventional prevention and control areas, and the use of chemical pesticides in each area decreased by 69.51%, 70.60% and 31.90%, respectively. Therefore, pesticide residues in the comprehensive control area were significantly lower than in the conventional control area. [Conclusion]  Compared to conventional control methods, comprehensive control not only effectively controlled G. molesta, but significantly reduced both the fruit decay rate and chemical pesticide use. These results indicate the advantages of comprehensive control for the prevention and control of G. molesta in pear orchards.
