The results of two years showed that planting alfalfa in apple orchard, preserving beneficial weed, summer grasses, increasing biodiversity, improving orchard ecological environment, protecting and multiplying natural enemies, and relying solely on parasitic wasps Control the damage of the golden moth continuously and effectively. The conservation of summer solstice in the no-till garden can also improve the natural control effect of the parasitic wasps of the golden moth. However, apple orchards of the tillage moths have less parasitic wasps and the golden moths are more harmful
