Abstract: To clarify the influence of different plants in apple orchard on the host selection behavior of Serica orientalis Motschulsky, and select the plants that have better repellent effect on Serica orientalis Motschulsky for agricultural control, from 2017 to 2018, an indoor test of Serica orientalis Motschulsky selection for 8 different plants was conducted, and 4 kinds of plants were selected for field intercropping. We observed and evaluated the repellent rate and leaf damage of different plants to Serica orientalis Motschulsky, and finally determined the plants with better repellent effect. The results showed that there were significant differences in the selection rate of the 8 species of plants. Wheat, barley, perilla and lavender had strong repellent effect on the Serica orientalis Motschulsky, and the selection rate of leaves was perilla> lavender> barley> wheat. The effect of onion, green garlic and mint on the Serica orientalis Motschulsky was not obvious, and the pepper seedlings had a strong trapping effect on the Serica orientalis Motschulsky. After intercropping wheat in the orchard, the repellent effect of Serica orientalis Motschulsky was the highest, and the leaf damage rate was the smallest. Therefore, priority should be given to the intercropping of wheat in production practice.
