When the locust plague comes, what tools do people use to prevent it?

There are many methods for controlling locusts, mainly including agricultural control (ecological control), biological control, chemical control, and physical control, and the goal of these prevention and control is to eliminate locusts and avoid the harm of locusts to crops. In the prevention and control of locusts, prevention should be the mainstay, and simple, cost-effective, and effective methods should be adopted according to local conditions and time.

The so-called prevention is to take action in a timely manner to kill locusts before a major locust plague occurs or when the locust occurrence is low and the locusts have not yet caused losses to the crops. Otherwise, taking action when the locust outbreak is severe will not only require more human and financial resources, but will also cause serious losses to crops.

Sometimes, peasant friends are anxious when they find locusts in the field, and in order to kill the locusts as soon as possible, they often first choose the method of spraying chemical pesticides to kill the locusts. Although this can kill locusts quickly, it also kills a large number of locusts' natural enemies and causes serious pesticide pollution to the environment and crops.

Sometimes pesticide poisoning can be caused by improper use of pesticides or poor mastery of application techniques. Therefore, overemphasizing the use of chemical pesticides to control locusts will have many adverse effects on peasants' production and livelihood. Therefore, in the prevention and control of locusts, chemical pesticides should not be used first, but those methods that are not polluting the environment and crops, and are safe for people and livestock and poultry, such as agricultural control and biological control, should be adopted.

When the occurrence of locusts is extremely serious, it is also necessary to scientifically use chemical pesticides to prevent and control locusts, and only in this way can the best control results be achieved.

Modify idle agricultural machinery, install two side strip suction ports (screen mesh to expand the scope of the mouth, and set up a trumpet-shaped fan suction machine behind), use agricultural machinery power to drive the fan to produce suction, and set up a locust collection pocket at the back end of the exhaust pipe behind the strip suction port, and the collection pocket is set at the mouth of the smoke exhaust cylinder, and the locusts are killed by using the high-temperature waste smoke discharged. Modified agricultural machinery is lined up and promoted in the locust area, and the effect of locust extermination is higher than that of pesticides.

1. Solve from the food chain. When the locust plague comes, we can also consider it from the food chain and reduce the planting of rice, barley, corn, etc., which locusts like to eat, to soybeans, fruit trees, etc.

2. Solve it from the natural enemy. When locusts come, we can herd chickens and ducks, and we can also raise bees, frogs, lizards, etc.

3. Solve it from the place of residence. Locusts also have a favorite place to live, they generally like to live in low-lying long grasslands, when locusts come, these places can be transformed into fish ponds, pond landscapes are okay.

4. Eat. Speaking of eating, we have to say that locust fried is also a delicacy, and it is okay to feel it once, but you can't eat too much.

5. Solve it biologically. Microsporidia has a lethal effect on locusts, it will die of disease after eating food with microsporidia, we can use neem to control.

6. Chemically solved. There are many chemical control methods, one is ground spraying, such as drone application; One is a chemical agent, such as pyrethroid oil, both of which can effectively solve locust plagues.

The occurrence of locust plagues is a natural disaster as well as a man-made disaster, and it has a certain regularity. Natural disasters refer to factors such as global warming, uneven droughts and floods, and abnormal river flows, which can easily lead to large-scale locust reproduction. Man-made disasters refer to the degradation of grasslands caused by poor management and inadequate climate monitoring, and multiple factors lead to locust outbreaks. There is a record of "locusts in the drought" in ancient books in China.

Several major locust plagues in Africa in recent years have also been linked to severe droughts in the region. The main reason for this phenomenon is that locusts are warm, dry insects that prefer to breed and survive, and that arid environments have many benefits for their reproduction, growth and survival. Because locusts lay their eggs in the soil, which is relatively firm, a moisture content of 10 to 20 is best for them to lay eggs.

Locust agricultural control: (1) Build water conservancy to ensure that there are no disasters in drought and flood. (2) Achieve large-scale barren land reclamation and planting, change the habitat environment of locusts, and reduce the area of the occurrence base.

3) Afforestation, change the microclimate of locust areas, and reduce the suitable habitat for locust spawning and reproduction. (4) Improve tillage and cultivation techniques to achieve the role of controlling locust eggs, change the layout of crops according to local conditions, and reduce locust infestation.

Biological control: (1) In locust-stricken areas, use high-efficiency and low-toxicity agricultural and biological pesticides to protect predatory natural enemies in locust areas. Chickens, ducks, geese and other poultry can also be stocked on the hillside for control.

2) Large-scale application of microsporidia.

How to get rid of locusts:

1. Build water conservancy to ensure that there are no disasters in drought and flood. Reclamation and planting, changing the habitat of locusts and reducing the area of the occurrence base.

2. In locust-stricken areas, use high-efficiency and low-toxicity agricultural and biological pesticides to protect the predatory natural enemies of locust areas. Chickens, ducks, geese and other poultry can also be stocked on the hillside for control.

3. Reduce the food source of locusts, many kinds of locusts eat corn, wheat, sorghum, rice, millet, etc., instead of soybeans, alfalfa, fruit trees, etc. Therefore, locusts can be controlled by planting as many soybeans, alfalfa, fruit trees and other trees as possible in locust areas.

4. Reduce the habitat of locusts, some locusts occur in low terrain, we can transform such plots into ponds, fish and shrimp, which can greatly reduce the habitat of locusts, and will also better control locusts.

You can also spray pesticides on a locust-infested grain field to give crops, and the locusts will die if they eat it.

To control locusts, you can spray a large amount of adhesive on the sand and spread the net on the crop field, and the locust flies to the crop field and sticks to it.

The locust is the grasshopper. Insect pests are slowly grown in secret cellars, and in sparsely populated places and where the grains are ripe, they become the base for locust health.

Throughout history, the cost of each locust plague has been very heavy. This year, the number of Asian locusts in Africa and even in Eastern Europe has reached 100 billion, and it can be said that there is no grass everywhere they go, resulting in a great reduction in grain production and extremely threatening people's normal life. The locust plague has been paid attention to in all dynasties, because the people take food as their sky, which is related to the most fundamental survival problem.

As long as it is not controlled, there will be a lot of hunger problems.

First, the locust swarm is very large. Due to the high reproduction rate of locusts and the speed of movement, as soon as they appear, they will be like the wind passing through the sky, and if effective measures are not taken, it will trigger a large number of chain reactions. After they are gathered, they have the ability to gnaw without any grass.

They mutate quickly, newborn, solitary, mild, and ashamed. But once there are more than 60 of them, the color changes and the personality changes. He became particularly irritable, aggressive, and had a great appetite, and began to march in groups.

After the encounter, they merge from time to time, and the group will get bigger and bigger.

Second, the harm is huge. Desert locusts and flying locusts are the most important agricultural pests and the most extinction of migratory pests.

Third, in-depth historical experience. It has been recorded in all Chinese dynasties that in the summer of 2002, more than 100 counties in 13 provinces, autonomous regions and municipalities, including Hebei and Xinjiang, were plagued by locust plagues in different ways, and 90 million mu of agricultural and pastoral areas were affected, resulting in great losses. Today, it is mainly locusts that have migrated from abroad.

Fourth, the risk of desert locust swarms invading China remains. Locusts will eat our crops and all green will be swept away, so we need to be prepared for the arrival of locusts and come up with a way to stop the locust plague. In nature, the food chain adheres to a state of relative harmony, and the ecological environment can be guaranteed and optimized.

Species extinction or endangerment affect biological chains and thus ecosystems; And the disaster of certain organisms will definitely destroy the biological chain and ecosystem.

The problem of locusts must be paid attention to, although the current science and technology are thriving, but the environmental problems are intensifying, especially the chain effect caused by climate warming, many viruses that have been silent for hundreds of millions of years are eager to try, many animals and plants have evolved from time to time to adapt to the environment, and have surpassed the original understanding of human beings, locusts are only the tip of the iceberg, and they must be paid attention to.

1. Ecological governance. To prevent the occurrence of locust plagues, we must first focus on the physiological characteristics of locusts. Locusts are controlled by improving the plant varieties and environment of the locust producing areas.

For example, locusts feed on food crops such as corn, wheat and rice, rather than alfalfa and fruit trees. So we can plant crops that locusts don't eat in locust plagues. For some low-lying places, they can be converted into fish ponds to reduce the living conditions of locusts.

Then increasing the vegetation cover of the area so that the locusts cannot lay eggs can also effectively reduce the locust infestation.

2. Biological control. Biological control will not affect the environment, and it can also ensure harmlessness to the health of humans and animals. In addition, it is simple and the input cost is relatively small, and the use of biological control is also the main way to control locusts.

We can use biological pesticides to control locusts, and now the more mature is locust microsporidia control technology. Locusts can develop a form of microsporidiasis after eating food containing microsporidiasis until they die. The disease is an epidemic by using food contamination to kill locusts and laying eggs containing microsporidia to spread among locust swarms.

After a single control, the disease can be endemic in locust swarms for many years.

3. Chemical substances. There have been professional data surveys that show that one of the main factors in the movement of locust swarms is caused by the burning of a substance called serotonin. So we can use this substance to control the development of locust swarms.

However, in the long term, pest control methods will not be completely innovative. This is because the chemicals used to neutralize serotonin are also capable of designing sheaths that can penetrate the locust's epidermis. And this chemical needs to be used only when locusts are alone.

Caves are simple, and at this time they are generally sparse targets for locusts to be distributed on the land. Therefore, more basic research on the physiology of locusts is needed to effectively reduce the damage of locusts.
