In recent years, with the in-depth promotion of green plant protection work, electric pest-killing lamps, which are pollution-free insecticide tools, have become more and more popular among users. Through practical tests, electric shock-killing insect lamps have displayed many types of insect-killing insect pests. Large, can significantly reduce the amount of eggs off the insects, and reduce the base number and density of insects and other characteristics, pest control effect is very significant, but also played its natural enemies to protect pests, delay the occurrence of insect resistance, harmless to humans and animals, etc. It fits well with the theme of green plant protection work.
The electric shock insecticidal lamp uses the insect phototaxis habits of the insect and uses the light wave of the corresponding wavelength to induce the high-voltage electric network to kill and reach the purpose of eliminating the adult insects. In the process of using electroshock insecticidal lamps, as long as the lights are turned on at night and the lights are turned off during the day, it is possible to eliminate a large number of pests, such as leafhoppers, clams, and rice planthoppers. In addition, electric shock insecticidal lamp is a new type of green insecticide device, and it is also the best choice for physical control of pests and diseases. The application of electrocution type insecticidal lamp to kill agricultural insect pests can reduce the drug dosage by about 67%, and the number of medications can be reduced by about 2/3, its ecological benefits are very significant.
Electric shock insecticidal lamps used in green plant protection work, can play an important role in promoting the development of green plant protection work, the benefits are mainly reflected in the following points: First, the insecticidal technology can reduce the use of chemical pesticides, reduce pesticides Environmental pollution; Second, it can delay the rate of change of pest resistance, protect natural enemies of pests, and realize harmless control; the third point is that it can save costs and reduce labor intensity, and liberate the labor force; Fourth, use pests to feed poultry and feed fish. It is a very good green organic feed. Therefore, electric shock insecticidal lamps are widely used in orchard production, cotton field production, rice production, plutonium production, forest pest detection and other fields, and become one of the important technical forces for the development of green agriculture.
