    By observing the locusts moving around the ring, we found some interesting behaviors. A small group of locusts moved randomly on the ring, but larger swarms of locusts began to travel in the same direction. These groups then spontaneously turn in the other direction.

    The more locusts in the swarm, the longer the transition interval and the more stable the colony. The best way for swarming insects to get the protein and salt they need is to eat each other. This is bad news for locusts who don't pay attention to their neighbors' movements.

    Therefore, when a locust is in a colony, any locust that is inconsistent with its neighbors will expose its fragile flanks and face a greater chance of cannibalization. By queuing, they will be safer, but it will also help to bring the colony together. <>

    So, in order for the locust swarms to fall apart, should we consider reducing their cannibalistic tendencies by providing other food**? Probably not. Feeding so many greedy people in a coordinated manner would be an almost impossible task.

    It can even boost the growth of bee colonies. Instead, our research shows how sensitive locust swarms are to randomness. If we can increase the randomness or noise that the body experiences, then we have the potential to separate it.

    This idea may be used as a swarm management strategy, using low-flying aircraft to create atmospheric disturbances to disturb locusts. However, the sheer size of the bee colony also makes this approach impractical. A typical locust swarm can cover several hundred square kilometers.

    Locusts can travel up to two kilometers in the air, and there are even reports that they fly over the entire ocean. Locusts can eat tens of millions of food a day. However, we hope that with further research, we can find better ways to break down bee colonies with similar methods.

    Currently, the most commonly used control method is pesticides. Sprayed from land or air vehicles, an entire colony can be targeted in a relatively short period of time. However, this has apparently led to some environmental problems.

    Perhaps more promising are the so-called biological control mechanisms. Natural predators such as wasps, birds, and reptiles may prove to be effective in deterring small bee colonies. However, in order to manage more mature bee colonies, newly developed target microbial biologics, such as fungi-based "green muscles", offer a larger-scale solution.

    However, one of the most effective ways to avoid the devastating effects of locust plagues is to prevent locust plagues from occurring in the first place. Significant resources are allocated for early warning. <>

    Because Yemen is relatively weak in economy and technology, and in the face of hundreds of millions of locusts, the local people want to directly eradicate them, but there is no effective way.

    Because it is the season of vigorous locust breeding, it is impossible to completely eradicate it, and they all have tenacious vitality.

    The main areas of the locust plague are India, Pakistan and East Africa.

    10 countries in East Africa, including Ethiopia, Somalia, Uganda, and Rwanda, have been affected by the yellow plague, and if it is not handled properly, the food in East Africa may run out, farmers will not harvest, and the yellow plague will continue to spread outward if it is not suppressed. Now that three countries in Ethiopia, Kenya and Somalia have directly declared food outages, our rough estimate is that 12 million people could be food insecure as a result of the locust infestation.

    The impact of the locust disaster is so great, mainly due to its strong vitality, reproductive ability and migration ability, you must know that even if the locust is against the wind, it can fly 150 kilometers a day, not to mention that if it is a downwind, it is simply a thousand miles a day, according to its vitality, although he survived for a long time, but his vitality is very tenacious, basically in any living conditions can survive tenaciously, and its reproductive ability is very terrifying, such as after three months of reproduction, The number of Emperors will increase by 20 times and 400 times after 6 months. If the growth of locusts is not curbed as soon as possible, it will be almost impossible to completely eradicate them in the later stage. Therefore, many countries now want to disinfect and kill locusts before they start a new round of reproduction, so as to curb the growth of locust populations.

    Such as:Today, the locust infestation area is mainly on both sides of the Red Sea in the Horn of Africa and in Southwest Asia, and there are 10 countries affected, such as Kenya, Ethiopia, Iran, India, Pakistan, etc. There are already many countries where emergency warnings have occurred for food. And worst of all, after months of locust infestations, there is nothing that can be done to stop it, and locusts in the Horn of Africa continue to breed and with the onset of the monsoon climate, new locust colonies that have bred in Kenya may re-enter Ethiopia and Somalia and then continue to migrate.

    What are some ways to eradicate locusts in Kenya with the locust plague hitting Kenya again? Is there a good way to deal with locusts, for now, there are roughly the following methods to get rid of locusts:

    1. Scientific testing finds the spawning ground while the locusts are still in the hatching stage and disposes of the eggs. The locusts do not live long, usually six months, during which the locusts will lay eggs and die naturally, and then the next batch of locusts will hatch and form a new disaster that will continue to plague people.

    Therefore, the most effective way to prevent locust plagues is to destroy the locust eggs as early as possible at the hatching stage. At present, there is basically no locust plague in China's agricultural areas, and locusts in Shandong, Hebei, and other places can be said to emerge once every few years, and they will be extinguished as soon as they appear, and they have no sense of existence.

    Two: biological locust extermination The so-called biological locust extermination is to cultivate the natural enemies of locusts, such as chickens, ducks, birds, frogs, etc., these animals eat locusts. There is a bird called the pink starling, and the main diet of this bird is locusts, and it eats about 150 of them a day on average.

    In areas where this bird gathers, locusts are barely visible and are eaten as they emerge. At present, biological control is also a means of locust control that we vigorously promote, and we attach great importance to it, and the effect is also very good. However, because the locust plague is generally measured in "tens of billions", the number is huge.

    Three: chemical locust extermination The so-called chemical locust extermination is the use of chemical agents to eliminate locusts in a large area, for example, there are some bacteria that can infect locusts and shorten their lifespan. For example, some chemicals can kill locusts directly.

    However, the chemical extermination of locusts is also very large, which will cause large-scale chemical pollution. And locusts move fast and often change direction, and it is not easy to track locust swarms with aircraft. For example, when an airplane sprays medicine to kill locusts, it often flies into the air, and the efficiency is not high.

    So in general, chemical locust extermination is usually a killer method.

    Generally speaking, the first way is **, our country is doing a good job in this area, so in the agricultural area, there is basically no locust plague (there are locusts, but there is no "plague"). In addition, some people often make up jokes on the Internet, saying that locust plagues occur abroad because foreigners don't know how to eat, and there are no locust plagues in China because we can eat them in China, and locusts dare not come. If you send Chinese foodies abroad, there will be no locusts.

    This is a typical jitter and nonsense. Because in fact, when it comes to eating locusts, we are really not much smarter than foreign countries. Africans often eat locusts, and they eat them in the same way as they are, they are all fried.

    But have the Africans eaten up the locust plague that is so dense that it is all over the world? Judging by this desert locust plague, judging by all the locust plagues in history, it is clear that there are none.

    First of all, we reclaim the land and plant to change the habitat of locusts and reduce the habitat of locusts. Secondly, in places where there are many locusts, spray pesticides on a large area to protect the predatory natural enemies of locusts. You can breed more chickens, ducks, geese and other poultry for control.

    We also need to cut off food sources for locusts and plant as many soybeans, alfalfa, fruit trees and other trees as possible.

    Natural factors are the main factor in the occurrence of locust plagues, but it is undeniable that there are quite a few human factors. First of all, we must pay attention to environmental protection, and we can use corresponding insecticides, and secondly, in the long run, in order to effectively prevent and control locust plagues, we must focus on ecological construction, and we must implement the four combinations of plant protection, biological protection, resource protection and environmental protection. In particular, it is necessary to ensure biological diversity and protect the natural enemies of locusts.

    Indian locusts are also called desert locusts, they will be indiscriminately planted in moist soil during the breeding season, with the warming of the earth's climate, the increase of rain, the reproductive success rate of desert locusts is getting higher and higher, with the increase in numbers, desert locusts have also mutated, will release phenylacetonitrile, so that birds will not prey on locusts.

    Fourth, the mechanical extermination of locusts can use all mechanical methods to catch locusts. This method of exterminating locusts is relatively low, but it can also eliminate some of them as much as possible.

    Where the locusts have struck, even the most basic crops are clean. Locusts can bring famine to a country, and locusts have brought me a terrible famine in history. Where the locusts passed, there was no greenery.

    And the locusts reproduce very quickly, and if the locusts are not eradicated and the locusts are not able to keep up with the reproduction rate of the locusts, it will not only bring disaster to India, but also to the whole world.

    The locusts could not survive the winter, so it was not ruled out that they would first go to Xinjiang to snatch cotton and cotton cloth reserves, and then set off after making cotton clothes. The other road was attacked along the Hexi Corridor to the Longshan area, and then the troops were divided into two routes, all the way continued to advance to the east, occupied Guanzhong, entered Henan, captured Xuzhou, and controlled the Qinling Huaihe area. The other road went south from Longshan into Sichuan, and then went east along the Yangtze River, occupying the middle and lower reaches of the Yangtze River. However, in a few months, all the north of the Yangtze River will fall, and there are ducks in the south of the Yangtze River that can withstand it for a while.

    However, when the fighting in the northern region is over and all the troops are pressed to the south of the Yangtze River, the situation will not be optimistic.

    The most effective measures to deal with locust plagues are cold isolation and suppression of the food chain. The low temperature in the plateau area is not suitable for the growth of locusts, which can effectively isolate the locust plague. You can also put more natural enemies such as frogs and birds.

    The locust plague is known as one of the three major natural disasters. In the event of such a disaster, crops will be severely affected. At present, the desert locust plague has entered India, and a large number of locusts have appeared in many places in the Indian capital. What is the specific reason for the high number of locusts in many parts of the Indian capital?

    In fact, locusts have invaded several states in central, western and northern India a few months ago, threatening food crops and vegetables in many places. According to FAO, this is the worst locust infestation in India in recent decades.

    Faced with the threat of locust plague, a large number of locusts have invaded, and although it has entered a state of high alert, India** seems to be powerless. In Rajasthan, the worst-hit state of locusts, several fire trucks and thousands of tractors were dispatched to eradicate locusts, and even drones were used to spray insecticides for the first time to eradicate locusts, but with little success.
