Abstract: The technology of natural enemy control and bumblebee pollination were integrated and applied to reduce the usage of chemical pesticides and lower pesticide residues, and to improve strawberry quality. On the strawberry in the greenhouse, taking the conventional management as the control, the mode of combining the natural enemy of strawberry pest with the bumblebee pollination was adopted to control strawberry pest incidence and improve the quality of fruit. The application of multiple natural enemies combined control technology has a better preventive effect, which lasted longer. The control effect on spider mite, whitefly and aphid reached 74.29%, 59.38% and 61.03%. Compared with artificial pollination, bumblebee pollination technology is better in shape and color of strawberry. After bumblebee pollination, the average single fruit weight, vitamin C content, solid matter content and solid acid ratio are significantly increased, and the rate of malformed fruit is significantly reduced. The results showed that the integrated technology of various natural enemies played a better control effect on preventing the occurrence of pests and reducing pesticide residues than traditional chemical control methods, and the technology of bumblebee pollination improved the quality, appearance, and weight of strawberry significantly.

Key words: bumblebee pollination, natural enemies, greenhouse strawberry
