What are the dangers of locusts, and why are locusts poisonous?

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.

Not all kinds of locusts can be eaten.

In fact, eating locusts is not the patent of modern people, locusts can be eaten and used medicinally, and they have existed since ancient times. It is recorded in the "Compendium of Materia Medica" that locusts can be used alone or dispensed with medicine to develop a variety of diseases, such as cough, shortness of breath, tetanus, acute and slow convulsions, high blood pressure, etc.

A large number of modern studies on the nutritional value of locusts show that the protein content of locusts is as high as more than 74%, and the vast majority of species of locusts contain more than ten kinds of amino acids, and the ratio of polyunsaturated fatty acids to saturated fatty acids is even higher than that of most animal fats, and the quality of oil is higher than that of rapeseed oil and similar to peanut oil. Generally speaking, locusts are a natural health food with high protein, low fat, low energy and rich in minerals, with complete nutrients, rich protein content, reasonable amino acid composition, and low fat content.

At our daily dining table, especially on the barbecue table, many people eat fried locusts and roasted locusts that are basically artificially bred or scattered. However, this does not mean that locusts can be eaten under all circumstances, nor does it mean that any locust can be eaten.

Locusts are able to "switch" between living alone and living in groups. The team found that the social locusts release a volatile compound, phenylacetonitrile, in large quantities, while the dispersed locusts do little synthetic phenylacetonitrile and are actually non-toxic, making it ideal for feeding poultry such as ducks or chickens. And social locusts, when attacked, immediately convert phenylacetonitrile into the highly toxic compound hydrocyanic acid.

When locusts gather in large numbers, their natural predators do not like to eat locusts, and this is why. At this time, the locusts are not only inedible to animals, but also to humans.

Why is it poisonous and others are very detailed, but it's eaten raw, and humans can cook... If it is fried or boiled in boiling water, it is not toxic and can be eaten.

Locusts are not venomous, they are herbivorous insects that are mainly found in tropical, temperate desert and grassland areas. Locusts are also a kind of food material, the whole world has the habit of making food with locusts, such as "fried grasshoppers, land flying shrimp, flying locust Tengda" and several other dishes are favored by consumers in major hotels and restaurants, because the taste of locusts is as delicious as shrimp, and the meat is soft. However, locusts usually contain parasite eggs, and if they are eaten, they must be treated at high temperatures.

Locust hazards.

There are more than 10,000 species of locusts in the world, of which about 300 species can cause harm to agriculture, forestry and animal husbandry.

Locusts are mainly harmful to the adult stage, the way to harm crops, mainly rely on chewing mouthparts to bite the leaves and other parts of the plant, the occurrence of mild cases (such as the situation we usually encounter when planting crops), will cause small holes on the leaves, which is the result of locust chewing, if it occurs more serious (such as the locust plague in East Africa), it will lead to all the leaves of the plant to be eaten, only the stems remain, and sometimes the stems will also be eaten, for agriculture, the economic loss is relatively large.

Locust plagues release large quantities of the volatile compound phenylacetonitrile, and when attacked, locusts immediately convert phenylacetonitrile into the highly toxic compound hydrocyanic acid. Therefore the locusts of the plague of locusts are poisonous. The plague of locusts is not edible.

Locusts, commonly known as "grasshoppers", belong to the order Orthoptera, including the species of grasshoppers, grasshoppers, and locusts, there are more than 10,000 species in the world, and more than 1,000 species in China, distributed in the tropical, temperate grasslands and desert areas of the world.

There is no doubt about this problem, and the locust plague has caused the greatest harm. Because locust plagues often occur during the dry season. In this way, the harvest was not daring, but the locusts ate the rest of the crop.

Then the peasant rations did not have. So, the famine that this brings is a great harm.

You must have seen the locusts sweeping in the sky recently, who are these locusts? Why is the locust plague so violent? Where do they come from?

Going to ** again? Will they come to China? What harm will it do to our crops?

What kind of impact will it have on ****?

Typical habitats suitable for desert locusts are semi-arid and arid areas, which usually live only in areas with less than 200 mm of annual precipitation and low vegetation coverage, covering about 16 million square kilometers of land in 30 countries in Europe, Asia and Africa.

In years when there were no locust plagues, if there was one word to describe desert locusts, it would probably be "dumbfounded", these blue-green locusts are dull, slow-moving, and somewhat shy, and will try to avoid their own kind;

But in the years of the locust outbreak, the same locusts turn bright yellow with black spots, and their mobility increases dramatically, forming large swarms, and moving elsewhere.

Food and Agriculture Organization of the United Nations (FAO): The locust population has increased by 64 million times in a year and a half, and a locust swarm of one square kilometer can eat the food rations of 10,000 people in a day, threatening the survival of the local population. The locust plague has caused the most damage to crops in East Africa in 25 years and Kenya in 70 years. Somalia and Ethiopia have declared a complete stagnation in agricultural production.

So far in 2019, it has been a year of wild spread of locusts originating from the Arabian Peninsula.

In early 2019, the first swarms flew to Yemen, Saudi Arabia and Iran to breed further before moving to East Africa. In the summer of 2019, large swarms of locusts were also forming along both sides of the Red Sea; It also crosses the Red Sea and the Gulf of Aden into Djibouti, Eritrea, Ethiopia and Somalia.

The first step is to go to the peninsula, and the second step is to get out of the peninsula.

It stands to reason that the location of the locusts should have been determined by this, but the anomaly came in waves.

In October 2019, East Africa experienced widespread and unusual autumn rainfall, culminating in a rare tropical cyclone Pawan that made landfall in Somalia in December, during which rainfall led to another wave of peak locust population growth.

By late December 2019, locust swarms had reached Somalia, Ethiopia and Kenya to run wild, eradicating more than 1.8 million tonnes of vegetation per day across 350 square kilometres of cropland and destroying 10,000 acres of farmland in Somalia and Ethiopia.

So, this is the harm of locusts.

The plague of locusts has spread to the border between Pakistan and India, from Africa to Central Asia and South Asia. From the news, we know that the development of this locust plague is very fast, from tens of billions to 400 billion, a 10-fold development in a short period of time!

At present, the discussion on the Internet is also very popular, and there are nearly 6 million people paying attention to Douyin, but most of them are locusts that are fried as soon as they enter China, a string of locusts is sold for 10 yuan, and the sky is flying in yuan, etc.

But we have to judge rationally, because locusts may also enter our country through the intersection of Yunnan and Guizhou, and the impact of locust plague on our country is also very huge, and it has also flooded many times in history, and the locust plague is currently regarded as one of the three major natural disasters combined with floods and droughts. Therefore, we must attach great importance to it. So in the face of this locust plague, what is its cause?

How terrible is this locust in East Africa?

Since December last year, locusts have been spreading in East Africa, with nearly 360 billion locusts at their peak in Kenya, Somalia and Ethiopia alone, and nearly 400 billion locusts now. Locusts travel to India and Pakistan, of which 40 billion locusts have reached the territory of India and Pakistan.

An adult locust can eat almost 2 grams of food a day, and if 360 billion locusts eat with their stomachs open, it will be 720,000 tons of 100 million kilograms! And the average person only needs to eat about 400 grams of food a day. Can you calculate how much food so many locusts eat in a day?

Of course, locusts also eat things that many people don't eat, so the actual impact on crops is not so great, but it is also quite scary.

And the locust thing, it didn't eat this piece of land, it stayed here and didn't move. Locusts can fly 100 to 150 kilometers a day, even if they fly against the wind. Basically, where the locusts pass, they can be eaten in an hour or two, which is why locust plagues, floods and droughts have become the three major natural disasters.

Some countries in East Africa are currently suffering from locust infestations, this time the locust plague started in Africa, then flew over the Red Sea and then into Europe and Asia, and has now been talking about India and Pakistan, due to the favorable weather conditions caused by climate change in these areas, the locust multiplication, the plague has continued, we can see from some reports that 20 million to 50 million locusts can cover 150 kilometers and eat 200 tons of crops a day.

There is also a report on data analysis, the number of locusts per square kilometer can reach 40 million, can fly 150 kilometers a day, and can eat 10,000 people's food in one day, and this locust disaster, many professional ** articles said, the number has reached nearly 400 billion, according to the above, can eat millions of tons of crops a day.

Locusts have always been regarded as a pest in our country, and there are many species. There are about 10,000 species of locusts in the world, of which more than 300 can cause harm to agriculture, forestry and animal husbandry. For example, during the planting of wheat, rice, corn, soybeans and other crops, we will often see locusts in the field, but the number of locusts at this time is very small, so it can be prevented by using pesticides.

Our peasant friends are particularly concerned about this locust plague, because if the locust plague comes, will it affect our country? At present, according to relevant experts, this locust plague will not have a significant impact on our country. There are two main reasons, first of all, the East African locust plague is mainly desert locusts, and China is not the distribution area of desert locusts, and the living conditions of desert locusts are not available in China; Secondly, China has complete control measures for the artistic conception of locust disasters.

Mainly through the strategy of combining treatment and treatment.

Now we know that locusts are a migratory pest, and this time the desert locusts in East Africa are one of the most destructive species, so although the environment in our country is not suitable for the survival of desert locusts, but the survival ability of locusts is extremely strong, so we should pay special attention to this locust.

Hello, according to news reports, a rare locust plague is sweeping through Southeast Asia and Eurasia. So how harmful is the locust plague:

1.In the history of our country, there have been locust plagues in every dynasty and generation, locusts will destroy crops, and if it is worse, it will destroy entire villages and cause famine.

2.Anyone who has seen a locust plague should know that thousands of locusts are like a sandstorm that has caused people to live in misery.

3.If the locust plague is not controlled, it will affect many surrounding areas.
