The development of green and environmentally friendly, harmless to life and health, and non-destructive to the ecology of plant pest physical control technology will become an important technology for pest control in the future.

[0003] Among the physical control technologies of plant pests, the acoustic method of killing insect eggs has been proven to be an effective technical means. The basic principle of acoustic killing of insect eggs is to use sound waves to act on insect eggs, and to destroy the organizational structure of the eggs through the physical effects of sound wave vibration, cavitation, etc., so that they lose their hatching ability and achieve the purpose of killing the eggs. Compared with pesticide pest control devices, acoustic insect egg killing devices have significant advantages such as no pesticide residues, no continuous environmental pollution, and no damage to the ecology. However, the main problem with the current acoustic insect egg killing device is that the action time is long.
