Abstract: A method for preparing a biopesticide preparation for preventing and controlling Solenopsis invicta comprising: a: preparing an agent containing pathogenic microorganisms for preventing and controlling Solenopsis invicta, the agent comprises Beauveria bassiana and sodium chloride, with a Beauveria bassiana spores to sodium chloride ratio of (1-8)×20 billion spores: 4.0-7.5 g; b: placing the agent into a solid container, and adding a corresponding amount of solution in a liquid container; inserting the solid container into the liquid container, wherein a retaining ring is stuck at the opening of the liquid container, a rubber gasket is pressed against the retaining ring, and a lid covers the rubber gasket and the retaining ring and is fixed to the opening of the liquid container.

Abstract: The present disclosure provides a lighting device for reducing bird strikes and a method for reducing bird strikes in a wind farm. The lighting device includes an illuminator, and the illuminator emits red light with a wavelength of 620-750 mm. In the present disclosure, the red light with a wavelength of 620-750 mm is used as a light source of the lighting device to reduce the attraction to birds; therefore, strikes of birds on the position of the lighting device can be reduced, overcoming a longstanding technical prejudice that people have generally accepted that blue light is used as a light source for reducing bird strikes because the red light is easy to attract birds, which are too sensitive to the blue light to be attracted easily.
