Locust damage and how to prevent it? What are the dangers of locusts?

Specific prevention and control methods for locust plagues.

1. Strengthen environmental protection. Nowadays, people do not have the awareness of environmental protection, do not pay attention to the protection of the environment at all, and only care about the immediate economic interests of the indiscriminate felling, resulting in a large reduction of vegetation, environmental damage, pollution, this is absolutely not possible.

We must protect the environment, plant more trees, and fundamentally solve the problem of locust plagues caused by the environment.

2. Use natural enemies to control locusts. You can introduce some locust-eating birds or poultry, and let them solve this harmful pest. For example, driving the ducks and chickens raised at home to the farmland and letting them hunt locusts not only solves the hatred in our hearts, but also allows them to eat "delicious food", killing two birds with one stone.

3. Spray pesticides to control locusts. You can choose to spray some drugs specifically to eliminate locusts, such as spraying with 25 ml of Ruijin special suspension agent mixed with 55 kg of water per mu.

Where there are more locusts, you can sprinkle some trichlorfon powder on some small leaves or small wood for control.

In short, there are many ways to control locusts, and you can find one that is suitable for you and easy to implement, and you can eliminate this pest as soon as possible.

Before the locusts hatch and unearth, it is necessary to mix with malathion ** and sprinkle it with fine soil to poison the larvae that have just hatched and hatched, which is easy to kill. Or use malathion to add Ruijin special spray to kill. You can also use poison bait in the evening to trap and kill, and the booby trap effect is better.

It can effectively control the number of adult worms. Attention should also be paid to protecting frogs, some predators of predatory beetles, and Metarhizium aeruginosa can also be used to eliminate adult insects.

Adults are the main harm objects, mainly harm leaf buds, after gnawing there will be mutilation, hollow phenomenon, serious will gnaw leaves, flower buds, only light rod preventive measures first control the number of insects, prevention and control of large-scale occurrence, if not controlled, it is necessary to quickly poison with pesticides, eliminate adult insects.

When it comes to locust plagues, peasant uncles often talk about changes in color, and this kind of locust disaster has brought huge economic losses to peasant uncles. It can completely destroy the growth of crops, and even make crops unharvestable, which is very hateful. So what are the specific methods that can be used to effectively prevent locust plagues?

Xiao Xiao will tell you about it carefully. Want better control of locusts.

3. Prevention and control methods (1) Biological control: protect and use natural enemy insects, and there are more parasitic natural enemies of red wax scales.

1.Harmful symptoms Adults are the main harm objects, mainly harm the leaf buds, after gnawing there will be mutilation, hollow phenomenon, severe will gnaw the leaves, flower buds, only the bare rod. The East Asian locust only eats grasses, which will cause these crops to be eaten.

2.Spread Eggs overwintering underground, about 1 to 3 generations can occur a year, and they are generally affected by factors such as temperature, food, and light.

3.Preventive measures First of all, control the number of insects, prevent and control large-scale occurrence, if not controlled, we must quickly poison with pesticides to eliminate adult insects.

4.Prevention and control methods Before the locusts hatch and are unearthed, they should be sprinkled with malathion ** mixed with fine soil to poison and kill the larvae that have just hatched and hatched, and it is easy to kill.

The damage of locusts isEating crops and leaving insect eggs to cause secondary damage and make it difficult for crops to recover.

1. Nibble on crops

Locusts are more terrifying for the gnawing of crops, and their gnawing is not like other pests, they will gnaw directly to the root system, which means that there will be basically no residue above the soil layer. Vegetables are generally relatively tender, and only the main branches are left that can be gnawed by trees, so vegetables basically can't leave anything.

2. Eggs left behind cause secondary damage

In order to survive after the locust plague is formed, the locusts will spread to the surrounding area, and during this time, they will basically eat constantly. As they spread to the surrounding areas, they lay eggs in various places and continue to spread their populations, which is why the plague of locusts grows larger and larger.

When the locusts have enough food, their reproductive efficiency is very terrible, and the small locusts grow up quickly, and the slow hatching of these eggs will cause secondary damage.

3. It makes it difficult to recover crops

This does have a great impact on growers, and the land left after the locust plague basically has no good plants, and basically only the root system remains.

For orchard growers, these fruit trees are basically half wasted, I don't know how long it will take to recover, for vegetable growers, it is necessary to prepare for replanting, which takes a long time, the investment is wasted, and we have to prepare new funds to recover, which is even more difficult.

Locusts are an important part of agricultural, forestry and animal husbandry ecosystems, and many harmful locust species can cause varying degrees of harm to agriculture, forestry and animal husbandry.

There are more than 1,000 species of locusts known in China, of which about 60 species can cause harm to agriculture, forestry and animal husbandry. The species that harm legumes, potatoes, sweet potatoes and other crops include short-winged locusts and benzene locusts. Cotton locusts and negative locusts can harm cotton. Bamboo locusts can seriously harm bamboo forests.

When it occurs, it can seriously harm pasture and crops and directly affect the development of agriculture and animal husbandry. According to the records of China's historical books for thousands of years, the locusts that cause devastating disasters in agriculture are mainly flying locusts, and it is believed that drought has the greatest chance rate or correlation with the occurrence of flying locusts in the same year, followed by drought in the previous year and first flooding and then drought, grasshoppers in patches.

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.

The way to eliminate locusts, in fact, if you want to eliminate Huang Zhong now, you can use some insecticides.

With 130 decibels of sound waves, locusts can be killed. Horns can be used to kill locusts in a targeted manner.

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.

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 problem of survival.

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 a single grass.

They mutate quickly, newborn, solitary, mild, and ashamed. But once there are more than 60 of them, the color changes and the character 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.

Locusts are not harmful to the body; Locusts are rich in active substances such as proteins, carbohydrates, insect hormones, and contain vitamins A, B, C, and trace elements such as phosphorus, calcium, iron, zinc, and manganese;

Locusts have a wide range of food, can eat wheat, rice, millet, corn, beans, tobacco, reeds, vegetables, fruit trees, forest trees and weeds leaves, young stems, flower buds and young fruits, etc., the leaves bite into notches or holes, when the occurrence of large crops can be eaten into a bare rod or all eaten, resulting in serious economic losses.
