What species is the desert locust? Why is there a food crisis? Is there a threat to our country?

An animal. Because this locust is very fond of eating plants. There is harm, but the harm caused will be small.

Desert locusts are a pest because this species affects the growth of crops, can harm crops, and lead to reduced crop yields. It is also a threat to our country and is likely to affect the development of agriculture.

It is a pest, and grain is its food, and there are more of them, so it will cause a food crisis, and there is no threat to our country.

Countries on the locust route did not react enough to bring the situation under control as soon as possible. In Yemen, years of civil war and lack of administrative capacity to prevent locust infestations have allowed locust swarms to grow and migrate unhindered to other countries; Parts of Somalia are controlled by Al-Shabaab terrorist groups, and it is impossible to control them. Since India is a neighbor of China, the news has received widespread attention on the Chinese internet.

However, some experts and scholars have analyzed that there is no record of large-scale migration of desert locusts to China in history, and due to China's climate and environment and the barrier of the Kunlun Mountains and the Himalayas in the border areas, it is unlikely that desert locusts will invade China on a large scale.

In recent years, locust outbreaks in China have been low in frequency, light in degree, and small in scale, which is related to the climate and environment, appropriate prevention and control measures, timely emergency response, and effective operation of the locust prevention and control system. However, it is also worth our vigilance that the severity of the locust plague has not led to a relaxation of people's mentality and a reduction in funding and scientific research. This year's desert locust plague has two causes.

First of all, last year, the occurrence base of desert locusts was relatively large, and the number of eggs laid was large.

Second, this year's heavy rains in Africa have caused desert locusts to hatch in the same place at the same time, forming large populations. This makes the desert locust more resistant to predators than human control measures can do"。Unusually abundant rainfall increases soil moisture, making it more suitable for the hatching of desert locust eggs.

At the same time, the vegetation is massively increased, and the larvae have enough food to grow. Under such favorable conditions, the number of locusts in the new generation can increase by 20 times compared to the previous one. Fueled by small populations and regional tensions, desert locusts have been breeding freely here for at least three generations.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Because of global climate changes, the number of desert locusts has surged, and abnormal rainfall is more suitable for desert locust eggs to hatch, a single desert locust swarm can eat the food rations of 10,000 people, and it is very difficult to catch them, causing a food crisis; The threat to China is relatively small, because the desert locusts have not yet crossed the barrier of the Tibetan Plateau into China; We should look at this matter with vigilance and come up with a response to the desert locust crisis, which is not yet coming.

Because the new generation of locusts is maturing, the locust plague is more widespread than before, and this density is very low and exists in a dispersed form; The threat to our country is likely to be relatively low; Locusts are natural predators and should be prevented by chemical means, because they cannot cross the barrier of the Tibetan Plateau into the country, and they should pay close attention to the dynamics of locusts outside the country.

This kind of disaster causes locusts to eat a lot of food, so it can lead to a food crisis. There is no threat to our country, because our country controls this aspect very well, and at the same time, it can be well governed, which also reflects the wisdom and intelligence of the Chinese.

Because the probability of entering our country is particularly low, it basically poses no threat to our country, and it should be viewed objectively, because the natural environment of this insect along the southern border is particularly suitable for survival, so it will cause a huge locust plague there, thus causing a food crisis.

Because once these things go to the place where there are crops, the locusts will frantically bite the crops, which leads to the crisis of some crops and cannot be better matured, and it is also dangerous to the country, because if there is no banker, the foundation of a country will also be affected.

This is because the desert locusts have been eating food all the time, and because the desert locusts are more numerous, the production of a lot of food has dropped sharply. This has led to a food crisis.

Because the population density of desert locusts is very low, they exist in a dispersed form, and they reproduce very quickly, which can easily damage crops and the ecological environment.

This locust is very aggressive, and they are also very fast at predation, and when a large number of people attack, they can quickly bite all the rice, and then it will cause a food crisis.

Introduction: When it comes to food production, many people are very concerned, after all, after having enough food, we can produce and live to provide enough energy. Although many people are no longer worried about food with the advancement of science and technology, sometimes pests and diseases do affect food production.

How do desert locusts cause a food crisis?

The desert locust is a type of locust, and the reason why the desert locust makes people feel panic is that the desert locust reproduces very quickly. At first, there is only a small group, but as the nutrients are replenished and the populations reproduce with each other, they become a large group. Moreover, the desert locust has the ability to fly, and after eating straw in one place, it will quickly fly to the next place, so the damage is continuous.

In addition, the desert locust is also relatively difficult to eliminate, and it takes a lot of energy to eliminate it. Therefore, the appearance of desert locusts will indeed cause a food crisis, and after the appearance of desert locusts, they will eat a lot of straw, and the straw will basically be gnawed to the pole. In this case, there is no way for the straw to grow again, and basically the grain is not harvested.

Therefore, the desert locust is very terrible, if there is a desert locust, it must be reported in time for prevention and control.

In fact, the production and manufacturing of grain is still very difficult, and farmers have finally grown food, so as ordinary people, we should cherish food. Refusing to overeat in your daily life, and not using overeating as a selling point, will only lead to a series of bad habits. In addition, in daily life, you should still pay attention to what you should eat, don't eat too much, and don't order too much when ordering, don't waste food in order to show off, which will also waste your money.

Only if everyone can cherish and care for food, then it will not be easy to cause a food crisis.

Because this creature is very fond of eating crops, very fond of eating grain, and often appears in large areas, so when this locust appears, it will cause a food crisis.

Desert locusts generally live in groups and usually eat crops, and the number of desert locusts is particularly large, which will affect the harvest of crops and cause food crises.

The desert locust is a very fast animal that reproduces rapidly and in more and more numbers, which leads to a large number of rice bites to death, which leads to a food crisis.

Desert locusts reproduce very quickly, and there are many of them, which can reach hundreds of billions, and they have to eat the same volume of food as themselves every day.

The natural predators of locusts are frogs.

Frogs and locusts live in the same type of ecological environment, where there are reeds, weeds in low-lying land, ponds, ditches, etc., are their good living places, so almost all frogs are the natural enemies of locusts. According to statistics, a single frog can kill more than 10,000 pests in a summer.

Locusts damage grasses and are agricultural pests, and they are very reproductive. Locusts reproduce every three weeks and have very little requirement for a spawning ground, as long as the soil is soft, they can reproduce almost anywhere. Moreover, the eggs are all underground, so they are not easily damaged.

The habits of locusts

1. The feeding habits of adults and locusts are the same, both are herbivorous, and the adult stage has strong nutritional supplementation, accounting for more than 75% of the total food in a lifetime. They bite the leaves and buds of plants with chewing mouthparts into gaps and holes, and in serious cases, they eat up the leaves and buds of large areas of plants, causing major economic losses in agriculture, forestry and animal husbandry.

2. Locusts feed on plant leaves, and like to feed on reeds, barnyard grass, white grass, dogtooth grass and artemisia plants, shrimp grass and samphire seeds. Some locust species are omnivorous and also eat insect carcasses, even those of their own kind.

3. Locusts do not have the habit of swarming and migrating, they often live in one place, generally scattered in the fields and grasses, and eat grasses, so they will also have certain harm to rice and bean crops.

In the worst countries, such as Kenya, this is the country's worst locust outbreak in 70 years. After leaving Africa, the locusts moved to Asia, and Pakistan and India were also invaded by swarms of locusts. The locust population is estimated to be close to 400 billion, with 40 million locusts per square kilometer.

They block out the sun and constantly move from place to place, leaving trails of destruction in their wake. Huge locust swarms have wreaked havoc on crops, and each square kilost eats enough food to feed 35,000 people a day.

According to scientists, the number of locusts will multiply as they reproduce and could reach a trillion by June if the population is brought under control. By that time, locusts are expected to eat hundreds of millions of people's food every day. In several locust-affected countries, crop losses are inevitable, such as India, where up to 50% is expected.

It is estimated that nearly 20 million people in East Africa face food shortages, exacerbating the already existing food and clothing problems in Africa. So, will the locust plague lead to a global food shortage? What will be the impact on our country?

The African desert locust swarm was born and hatched in Africa, and has now grown to a scale of 400 billion, flying through the sky and heading east. It is worth noting that before India, African desert locust swarms passed mainly through agricultural developing countries. In other words, the food production is not very high, just enough for the local people to survive.

However, there is a lot of greenery here, and Africa's hungry desert locust swarms are determined to eradicate them whenever they see greenery. As a result, wild herbs and other things that could feed them were wiped out, which directly led to food shortages and the danger of starvation for nearly 20 million people. Swarms of desert locusts have flown across deserts, hills and oceans to India, where the global food security line will be set within the next year.

It was also the last stop for most African desert locust swarms for many years.

Not or at all.

The African locust migration benefits from modest elevation changes and a climate that is almost identical along the way. So in West Asia and North Africa, the African locust spread very quickly, and even further invaded South Asia. But if you want to enter China, there are Himalayas, the Qinghai-Tibet Plateau is blocked, and the cold and hypoxic environment along the way is extremely unfriendly to insects that migrate over long distances.

Even if the African locust enters China, it still faces interspecific competition from the native locusts in China. Not to mention the distribution of natural enemies such as ducks and wild insectivorous birds in our country.

The humid and cold winter environment in our country is not conducive to the settlement of African locusts in our country.

Of course, the reason why it is "basically none" is because the expansion of the locust plague will make international food ****, especially considering that South Asia is also an important rice producing area in the world. Therefore, it is not excluded that it will have an indirect impact on China's economy and agriculture at other levels.

Definitely not, although the point of occurrence is close to us, but there are Himalayas in the way, you can't fly over at all, locusts live in dry and hot places, and the Chinese Himalayas are so cold.

Yes. First of all, the locusts themselves multiply rapidly, and hundreds of millions of locusts pass through the crops, and there is basically no grain left. In addition, many large grain countries are relatively backward and have no good means to deal with locusts, resulting in a shortage of food in the world.

No, the locust plague is only a region, and it cannot be a global locust plague, so it will not have a security impact on the whole world.

Locust plagues do not pose a threat to the whole world at the same time. Because there is a certain amount of food reserves all over the world, which can be distributed to all parts of the world at any time.

If the time is short, there are food reserves in various countries. However, over time, it will affect food production and cause food shortages.

No, locusts can also be roasted and eaten!

No, our country will have enough food to eat for three years.

The world is still facing a food crisis, and locust infestation has existed since ancient times. Because of their large size, strong adaptability, and large numbers, desert locusts have caused a large-scale reduction in grain production.

Because desert locusts breed in the desert and do not live exclusively in the desert, they can also pose a threat to vegetation outside the desert.

Because locusts eat the crops planted by people, a large number of locusts will gnaw what they planted, and the crops will die, and human beings will have no food**.
