Two, the mankind have just constantly struggled with insect since having civilization. The maximally effective means of current pest control are chemical methodes, are namely constructed to the pesticide of chemically parasite killing. The advantage of agricultural insecticide is the effect that no matter large or small scope all can reach eliminating pest, it is ensured that crop is had a good harvest. But the method for this deinsectization there is also critical defect, it is simply that environment is had a strong impact on, and remaining family medicine can be deposited on crops, has influence on the healthy of people. Here it is environmental pollution, food pollution. Life-time service pesticide still more, insect can develop immunity to drugs. So the method that people consider whether through being everlasting to have better pest control.

Three, nineteen sixties, it was found that laser. The achievement in research of laser is plentiful and substantial for these years, is applied to communication and military aspect in a large number.

The laser itself formed can not directly produce electricity, and heat kills off the insect pests. The attack of insect is high light by it. the strong light compound eye by insect, simple eye, the sensitive tip of feeler, or thin, transparent mucosa, the neuroganglion (nervus centralis) affecting insect causes insect blind, blindly, dizzy, rotates, out of control, escapes. Finally owing to neuroganglion is impaired and dead. It is dead that this and some pesticide cause insect neurotoxic, and its mechanism is walked back and forth mutually. Can say it is different Qu Ertong work. Plant by the strong illumination of laser, it does not have neuroganglion, will not produce the injury that insect is the same. And lower powered laser does not produce heat and will not burn plant. Thus reach killing pests, and do not hinder the purpose of crop.
