The locust plague is raging, how should human beings respond with tact?

Generally speaking, the response to the locust plague includes: protection and use of natural enemies of locusts, such as ants, beetles, coriander, insectivorous flies, young beeflies and other insects, can also be sprayed with chemical pesticides to eliminate locusts, but must be strictly in accordance with the operating procedures for the use of pesticides, so as not to cause environmental pollution. The most fundamental method is to protect the environment and reduce the locust spawning grounds, and now high-tech has been used at home and abroad to eliminate locusts, and the location and area of locust plagues have been greatly improved.

China is a big agricultural country, since ancient times there are many ways to control locusts, such as moderately increasing the number of natural enemies of locusts, birds, frogs and poultry all regard locusts as a delicacy, protecting vegetation is also a more effective method, increasing the coverage area of vegetation, can also play a better role in eliminating locusts。But these only apply to small areas of locust infestations.

In the face of this year's locust plague, it is still possible to use aircraft to spray high-efficiency, low-toxicity, low-residue counterpart pesticides, which can effectively deal with the locust plague, but now we have begun to use high technology to control the locust plagueFor example, the use of satellite remote sensing, satellite positioning systems, geographic information systems and meteorological data information on the location and area of locust plagues can be comprehensively and effectively controlled.

However, this time the locusts started from African countries, some African countries have a poor economic level, and the overall state is relatively backward, so many infrastructure are at a backward level, but the method of using aircraft to spread pesticides is still more feasible for them, spraying pesticides can kill a large number of locusts in a short time, and can also curb the reproduction rate of locusts to a certain extentHowever, pesticides must be selected that are effective and do not cause harm to the environment and other animals, plants and human health. In this way, there will be no damage to people and the environment.

The plague of locusts is coming, and humans need medicine to eradicate them. Such locusts are particularly reproductive, and if they are simply physically destroyed, it will be impossible.

1. Burning locusts. The larvae of locusts survive by biting on the leaves and stems of plants, and setting fire to them in dense areas can have good results.

2. Cultivating and protecting the natural enemies of locusts. Birds, frogs, crickets, moths and even parasitic insects can "eat locusts" or slow down their reproduction.

3. Harvest crops early and hungry locusts. Gradually, people have figured out that locust plagues are at their worst when the crops are ripe. Therefore, instead of waiting until the crops are fully ripe to feed the locusts, it is better to harvest early.

Raise a large number of locust predators, such as frogs, ducks, etc. The planted plants should be harvested as soon as they are ripe to avoid no harvest. Plant plants that locusts like, and they will turn a blind eye.

You can raise a group of small birds that can eat locusts, such as sparrows, etc., and you can also kill them with medicine.

Humans can cultivate and protect the natural enemies of locusts, such as birds, frogs, etc., and can also plant more crops that locusts do not like, and so on.

Raising chickens is a few different ways to deal with locusts.

In recent years, as an edible insect, locusts still have a certain breeding area in China. However, wild locusts are a pest, and locusts feed on various crops, which seriously affects the growth and yield of crops. In particular, locusts are very easy to form locust plagues because of their ability to reproduce and adapt strongly, which seriously affects economic benefits.

So how can we prevent locust plagues?

1. Ecological governance. To prevent the occurrence of locust plagues, we must first focus on the physiological characteristics of locusts. Locusts are controlled by improving the plant varieties and environment of the locust producing areas.

For example, locusts feed on food crops such as corn, wheat and rice, rather than alfalfa and fruit trees. So we can plant crops that locusts don't eat in locust plagues. For some low-lying places, they can be converted into fish ponds to reduce the living conditions of locusts.

Then increasing the vegetation cover of the area so that the locusts cannot lay eggs can also effectively reduce the locust infestation.

2. Biological control. Biological control will not affect the environment, and it can also ensure harmlessness to the health of humans and animals. In addition, it is simple and the input cost is relatively small, and the use of biological control is also the main way to control locusts.

We can use biological pesticides to control locusts, and now the more mature is locust microsporidia control technology. Locusts can develop a form of microsporidiasis after eating food containing microsporidiasis until they die. The disease is an epidemic by using food contamination to kill locusts and laying eggs containing microsporidia to spread among locust swarms.

After a single control, the disease can be endemic in locust swarms for many years.

3. Chemical substances. There have been professional data studies that have shown that one of the main factors in locust swarm movement is caused by a serotonin substance. So we can use this substance to control the development of locust swarms.

However, in the long term, pest control methods will not be completely innovative. This is because the chemicals used to neutralize serotonin are also capable of designing sheaths that can penetrate the locust's epidermis. And this chemical needs to be used only when locusts are alone.

The prevention of locust plagues should focus on sustainable development. In order to kill locusts as soon as possible, many people will choose chemical pesticides for control, but this is only an emergency method and cannot be used for a long time. Therefore, this will not only kill the locusts quickly, but also eliminate the natural enemies of the locusts, which is also very detrimental to the growth of crops.

Therefore, when we control locusts, we should pay attention to ecological management and biological control. It is necessary to choose simple, economical, and effective methods according to the actual situation to ensure the long-term development of agriculture.

Summary. There is a certain scientific truth in the expert's **, we know from the junior high school biology when we know that the occurrence of locust plague and temperature and climate have a great relationship, as the global temperature rises and warms, it is bound to affect the large climate and environment, and the locust plague is easy to flood in the state of temperature warming and mild environment, which is the truth that can be known from middle school, and with the warming of the climate, the vegetation grows luxuriantly, and the yellow food is sufficient to cause the number of locust plague groups to surge. It is very harmful to plants and our agriculture. <>

What are the ways to deal with locust plagues?

1. Protect the environment: When locusts lay eggs, they should be carried out in areas with vegetation coverage rate of less than 50%, so it is necessary to protect the environment to improve the vegetation coverage rate and reduce the occurrence of locust plagues. 2. Pharmaceutical prevention and control

The agent is sprayed with water with high-efficiency and low-toxicity counterpart, and attention should be paid to monitoring after application, and the effect of pesticide prevention and control should be checked within seven days, and if the effect is poor, it should be supplemented. 3. Prevention and control of natural enemies: protect the natural enemies of locusts such as Chinese bees, chickens, ducks, etc., to inhibit the growth of locusts.

When a locust plague appears, it is difficult to control it by human beings alone, because the number of locust plagues is so huge that they will be overwhelming when they come. The only way to deal with the locust plague is to spray pesticides or wait six months for the locusts to die on their own.

At present, the best way for human beings to control locusts is to use pesticides, pesticides are relatively cheap and can be used in a large area, and pesticides can also be mixed in a variety of ways to reduce drug resistance.

Find a cure for the root cause, because it is useless to treat the symptoms but not the root cause. And it is very likely to bring repeated locust plagues, which can change the living space of locusts.

The first step is to identify the natural enemies of locusts to deal with them, such as sending some ducks, and at the same time intensify scientific research to produce targeted locust insecticides to deal with this disaster.

If we want to completely eradicate locusts, we can only use pesticides at this stage, and the others cannot reach the level of complete eradication, but we can do a good job of defense in advance, we can destroy their living environment, reclaim fields to kill locust eggs, and raise their natural enemies.
