As we all know, onion is a must-have auxiliary condiment in every household. Due to the increasing demand and the state's additional subsidy policy for farmers, more and more farmers in my country are growing onions. However, as more onions are grown, the pest problem is getting worse. The use of pesticides makes the pests resistant and causes a vicious circle to the environment. Therefore, people gradually begin to use agricultural solar insecticidal lamps to deal with pests.

Onions are loved by the beet armyworm, which is phototactic. The agricultural solar insecticidal lamp uses this feature of the noctuid moth to trap the noctuid moth. After testing, the effect is remarkable. After the use of solar insecticidal lamps, the number of pests is significantly reduced, and there is no need to worry about the frequent reproduction of pests, which will reduce the yield of onions, and it also has a good protective effect on the ecological environment.

The construction of ecological civilization is the fundamental plan for the development and growth of the Chinese nation. Therefore, protecting the ecological environment is our current responsibility, and the use of agricultural solar insecticidal lamps is one of our measures to protect the ecological environment. May the world's ecological environment get better and better with the continuous efforts of human beings.
