If you are a new farmer who has been rooted in the field for a long time, or doing agriculture-related work, I believe you must have heard of the "grass moth" and hated it to the bone! This insect is extremely destructive, and if it is not prevented and controlled in time, it will seriously affect the yield and harvest of crops. So, what exactly is the meadow moth?
The grassland night moth, also known as the autumn armyworm, is a major agricultural pest that originated in the Americas and is extremely destructive. This seemingly inconspicuous bug was included in the world's top ten plant pest "blacklist" in 2017 and was also a major migratory pest in the 2018 FAO global warning.
A single meadow moth larvae can destroy a plant, while a moth can lay 1,000 eggs. Moreover, the grassland night moth has the characteristics of wide suitable growth range, long migration distance, strong reproductive ability and heavy damage loss. It can be said that the grassland night moth is a landmark event and landmark organism for the invasion of alien species, and it is also a invasive alien species with great destructive effect. How to prevent it has always been a scientific problem.
Biological invasions that migrate are difficult to control, and the characteristics of the grass moth determine that they can quickly become powerful creatures without natural enemies. Because of the three characteristics of the grassland moth - it can eat, grow, and fly! It is decided that they can "look at the crowd" and quickly dominate one side and become a harmful species that lacks or has no natural enemies.
The control of the grassland moth has always been a major agricultural problem. How to effectively prevent it? The first thing that comes to mind is pesticide pest killing, but this method is extremely polluting and easy for pests to produce antibodies, and it will be difficult to ensure the intensity of insecticide in the coming year. The most important thing is that pesticides are extremely harmful to the human body, and crops may also contain residual liquids that affect food health. Based on more environmental protection considerations, various places now promote green prevention and control, and control more green insecticidal methods such as installing solar insecticidal lamps in the fields. It is suitable for all kinds of agricultural and forestry crops, tea gardens, rice bases, cotton bases, vegetable bases, as well as trees, flowers, orchards, aquaculture, etc. The production process of pesticides does not pollute the environment and saves energy.
