What are the bee releasing methods?

According to the distribution of the target pest, different bee releasing methods are used. When the distribution of pests is more uniform, you can use each plant to release bees or release bees in alternate rows and plants; if the distribution of pests is more concentrated, you can use the center to release bees, with the concentrated area of the affected plant as the release point, and the distance between the release points is 40 to 80 meters.
