Armyworms have no diapause and can reproduce throughout the year as long as the conditions are right. The generation number of armyworms in my country mainly varies with latitude, and the higher the latitude, the fewer the generations. Armyworms can eat more than 100 species of plants, especially grasses, corn, and transfer damage in groups. When armyworm occurs, the whole piece of corn can be eaten, and the silk kernels of the ear of corn can be eaten, which has a great impact on the yield and quality of corn, resulting in reduced yield or even no harvest. In the control process, physical control means are necessary, and the application of insecticidal lamps is also required.
 
There are several physical methods we can use to control pests, such as light trapping and killing with solar vibrating insecticidal lamps, or radiation-induced sterility. These methods are simple and easy to do. The hanging height of the corn insecticidal lamp: the hanging height of the frequency vibration insecticidal lamp should be about 2 meters. Corn insecticidal lamp control area: the distance between two lamps is 150 ~ 200 meters, and the control area of ​​a single lamp is 30 ~ 50 mu. Turn-on time of corn insecticidal lamp: according to the start and end of overwintering adult eclosion, turn on at the beginning of eclosion and end at the end of eclosion. The lights are usually turned on at 7:30 pm and turned off at 3:00 am.
 
The solar frequency vibration insecticidal lamp can store the electricity needed for 3-4 days in the sun. A single lamp can "guard" nearly 60 acres of fields. It can not only attract and trap small insects such as moths, mosquitoes, and flies, but also large insects such as armyworms, scarabs, rhino horns, and long beetles. Because all traps are adults, killing one pest is equivalent to breaking hundreds of eggs. This not only saves the cost of planting pesticides, but also reduces the pesticide residues in agricultural products, thus supporting a "protective umbrella" for the green growth of corn.
 
There are many kinds of corn pests and diseases, and the growth stages and damage stages of each pest are also different. Therefore, it is necessary to comprehensively consider various factors to control the pests. Take corresponding measures to fundamentally eradicate pests, so as to achieve a bumper corn harvest. In the stage of pest control, we should not blindly pursue the quality of corn, but also pay attention to environmental protection at all times, and try to adopt methods that are less harmful to the environment.
