In the development of green, pollution-free agricultural production, insecticidal lamps are used as an important plant protection device. The greatest advantage of the insecticidal lamp is its ability to kill insects, and it does not pollute the agricultural environment. This is very much in line with the requirements of pollution-free green. From the perspective of the current application of insecticidal lamps in major regions, although there are many types, they all have a common feature. They use light to trap and kill pests, and they all adopt yellow in appearance. So what science does this design have? What's the reason?

First of all, the light of insecticidal lamps and the use of light waves not only make up for the lack of light trapping and killing of insect pests, but also make it possible for insects to prolong their activity cycle under the interference of light waves, thus achieving the purpose of increasing the number of traps. For example, bollworm, 3 activity cycles per night, can make the mixed flight period, mating period, homing period, if each active period is extended by 30 minutes, you can increase the ambush rate. Secondly, I talked about the principle of the use of insecticidal lamp colors. After research, I discovered that most of the pests like yellow, and grasshoppers, ladybugs, and other beneficial insects like green, so after turning on the lights at night, the light of the insecticidal lamp will be The editor is yellow-green, this is to make a large number of pests like yellow flutter light, and like green grasshoppers, ladybugs and other beneficial insects are less fluttering lights, greatly increasing the pest killing rate.
Of course, with the deepening of biological research and the development of science and technology, insecticidal lamps have not only adopted the technique of light trapping, but they have integrated modern light, electricity, numerical control technology and bio-information technology, light collection, wave, The integrated application technology of color and taste not only effectively kills adults, reduces the amount of eggs laid in the field, and reduces the number of insect pests. It also serves the purpose of controlling diseases and pests, and it also reduces the labor intensity of workers and improves the agricultural environment. The idea of ​​using insecticidal lamps to develop green, pollution-free agriculture was successful.
