Embodiment 2
[0054] Example 2 The effect of the winged tea aphid repellent is significantly better than that of the single-component repellent
[0055] 1 Materials and methods
[0056] From 12:00 to 14:00 on September 8, 2019, a tea garden where tea aphids have seriously occurred over the years was selected in the tea area of Anji County, Zhejiang Province. It was divided into 5 areas with a distance of 20m from each other. One repellent was placed in each area. Each area is 1 treatment, each treatment is 2 mu of tea garden, and 5 treatments are randomly set.
[0057] CK test area: with an area of 2 mu, 20 light green insect-attracting boards are placed, and the distance between the boards is 10m×15m. The bottom edge of each insect trap is slightly higher than the tea tip, and a rubber head containing 200 μL of n-hexane is tied on the tea branch in the tea bush 1-2m away from the insect trap, that is, the n-hexane core.
