Why do locusts move in swarms? Why do swarms of locusts have toxins

Species are made up of large and small groups, and sociality is also a fundamental attribute of living things. This helps the species to compete with other species, effectively "ignoring" intraspecific struggles.

Because they like to fight in groups.

Locusts are a common insect that usually comes in swarms. Many people know that locusts can have a devastating impact on crops and the natural environment when they move in swarms. Qinghui opened her eyes but I believe that many people do not know very well why locusts swarm and have toxins, so I will introduce and analyze this problem.

Why do locusts swarm toxins? The main reason is to avoid the attack of natural enemies and improve their competitiveness. When locusts swarm, they produce a substance called "swarm behavior", which affects the locust's nervous system, making the locust more sensitive and active.

At the same time, toxins can also poison the blood in the body of swarms of locusts, which is an effective defense against natural predators.

It is important to note that the reason for locust swarms is not limited to the need to survive. In fact, many locusts operate in relatively spacious environments, but in the face of extreme environmental stresses, such as drought and food shortages, locusts form large colonies to cope with difficult situations.

By extension, locust toxins are expected to play an important role in the biomedical field. In recent years, more and more studies have shown that locust toxins have anti-inflammatory, anti-cancer, and lethal cell functions. As a result, these natural medicines are expected to be used for a range of diseases and contribute to medical science.

Overall, locust swarms produce toxins mainly in response to attacks from natural predators and to improve their own competitiveness, which can increase the survival rate of locusts under alarming environmental stress. Locust toxins also have a well-known potential application value for the biomedical field, and these natural medicines may be expected to be used for a series of diseases in the future, becoming an important part of the history of medical development. <>

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.

4. Some locusts usually use their wings to send out "**" to attract mates and tell other male locusts to leave the place. Different species of locusts use different methods of making "**", some of them use the sharp forks on their hind legs to scrape the edges of their front wings to make a sound, or they make their wings rub against each other to make a sound.

Locusts are good at flying and jumping, and a pair of antennae on their heads are organs that combine the senses of smell and touch. Its chewing mouthparts have a pair of large, toothed jaws that bite through the stems and leaves of plants. It has a strong hind foot and relies mainly on its hind foot when jumping.

When locusts fly, the hindwings play a major role, and when they are at rest, the forewings cover the hindwings for protection.

Locusts make jumps on their hind feet. The front, middle and hind thorax of locusts each have 1 pair of feet, which are called forefeet, middle feet and hind feet respectively, and the feet are segmented, and the hind feet are more developed, suitable for jumping, also called jumping feet.

<> locusts prefer to live on the edge of fields and in grass. Locusts are herbivorous insects, which bite the leaves and flower buds of plants with chewing mouthparts, and holes will appear, and in severe cases, the leaves and flower buds of large areas of plants will be eaten up, causing major economic losses in agriculture, forestry and animal husbandry.

Because the reproduction ability of locusts is very strong, a pair of locusts can produce dozens of small locusts, and the development is still fast, and there can be thousands of locusts in one night, and there is no need to gather at all.

Locusts can gather into hundreds of billions in a short period of time, this is specifically because locusts have a very strong reproductive ability, and their reproductive cycle time is also relatively short, not only the total number of eggs laid by locusts each time is also very large, so locusts can gather a lot in a short period of time, I don't know about locusts, I don't know about locusts, only according to TV dramas and the Internet I have seen their photos, but I really haven't seen the entity, but when it comes to locusts, it is not easy for everyone to think of it is a good thing, Because it is a well-known pest, it can make everyone who has worked hard for a year get nothing.

And a recent big news is about the locust plague, the locust plague was originally in Pakistan gradually, but it didn't take long for a lot of agglomeration, and is still spreading again, many of our country is under the threat of locusts, the generation of locusts has indeed changed our lives, food crops are more seriously limited, and even stopped, everyone's basic life has suffered from the threat, if this kind of situation has been continued, the result will be unpredictable.

Locusts are often difficult to solve, because its reproductive ability is very strong, it can reproduce a lot in a short time, and the survival ability is also very strong, even in the natural environment is very extreme, it can survive, and they lay eggs everywhere, each female locust can lay about 80 eggs at a time, this reproductive ability is really not covered, it has far exceeded people dozens of times, so it must not be easy to solve them.

And the survival rate of larvae is also very high, and the evolution of locusts is also very special, it is different from mammals must grow and develop from shallow to deep, locusts are not juvenile this link, it can enter from eggs to nymphs at the same time, and their navigation ability is also strong, it is especially convenient to transfer.

Before the outbreak, many locust eggs were already in the land, which is why so many locusts appeared in an instant and had a particularly strong reproductive ability, and a locust could lay a lot of eggs.

This is because locusts have a very strong ability to reproduce and survive, so they can gather hundreds of billions in a short period of time.

Scientific studies have found that locusts can easily expose their weak flanks to their own kind and be eaten if they are in charge of their own foraging activities. Therefore, they must maintain a coordinated and consistent line of action to avoid being cannibalized by their own kind.

There are more than 10,000 species of locusts in the world, and more than 1,000 species in China, which are distributed in tropical and temperate grasslands and desert areas all over the world.

There is nothing more terrifying about locusts than their collective actions. Tens of thousands of locusts move in unison, chewing on the plants and crops in the places they pass through, causing devastation, bare land, and even conquering cities, which becomes a plague of locusts.

For many years, people have not understood the unified action of locusts, because locusts have no language, no unified thinking, and no unified command.

Because locusts reproduce very quickly, they can gather into hundreds of billions in such a short period of time. The rate of reproduction of locusts increases geometrically, so the rate of reproduction is very fast.

Locusts can lay 50 to 100 eggs at a time. They can hatch in 21 days and can produce tens of thousands of eggs as long as the temperature conditions are right. As long as there is a shortage of food, they will migrate. So they can gather hundreds of billions in a very short period of time.

In a large area of severe drought for a long time, after a good period of growth, breeding and feeding, the locusts will have a wider spawning area, and the water of the plant will be reduced, which is also more conducive to their grazing; Locusts are very reproductive, a female can lay about 50,100 eggs at a time, and with their very short egging time, they can produce thousands of eggs under the right conditions.

Because locusts multiply very quickly; There are about 60 eggs in each egg mass, and there can be about 4,500 egg masses per square meter of land, so there are many larvae that reproduce each time.
