Why do biological scientists not recommend that people exterminate locusts?

1 The best way to deal with locust infestations is to plan ahead for a rainy day, in densely populated arable land areas, in addition to spraying targeted pesticides, deep ploughing of the land in spring and autumn, so that the deep soil can be turned over to the ground to freeze the eggs or sunburned.

2 The natural enemies of locusts are very extensive, and the use of biological natural enemies to kill locusts is also a very efficient method, usually the natural enemies of locusts are birds, poultry, frogs, etc., and the protection of birds and frogs is to protect the environment from being harassed by locusts, and the method of grazing poultry can be adopted in large areas of grassland or woodland.

3. Lay good basic water conservancy facilities, change the environment in which wasteland planting disturbs the hatching of insect eggs, and change the microclimate area suitable for locusts.

4 Microbial natural enemies are used to widely spread fungal robes that can kill locusts, and the fungal robes are used to grow in locusts and kill hosts.

5. Locusts have high protein and low fat, and contain more than a dozen kinds of high-grade amino acids and other trace inorganic elements that are very beneficial to the human body, which are very conducive to human metabolism, growth and development and anti-aging. Locusts are still a delicacy in some areas of our country, and artificial breeding is currently being developed in many places; In addition, locusts are also an authentic Chinese medicinal material, and Li Shizhen's "Compendium of Materia Medica" has detailed medical descriptions.

The problem of locust plague management is a huge challenge in the world, and all countries have a long way to go in this regard, and our country has been effective in the management and prevention and control of locust plague, but it is still facing certain risk pressure, and at the same time, this problem also needs to strengthen international cooperation to jointly respond to this natural disaster.

Biological scientists do not suggest that the reason for the extinction of locusts should be the biological chain.

<> locusts are widely distributed in China, and the damage is also relatively serious, and they mainly harm grasses, which are agricultural pests. At the same time, locusts also have certain research and therapeutic value for humans.

Before the locusts hatch and unearth, it is necessary to mix with malathion ** and sprinkle it with fine soil to poison the larvae that have just hatched and hatched, which is easy to kill. Or use malathion to add sharp laughter to the spray to kill. You can also use poison bait in the evening to trap and kill, and the booby trap effect is better.

This effect can be used to control the number of adult worms. Attention should also be paid to protecting frogs, some predators of predatory beetles, and Metarhizium aeruginosa can also be used to eliminate adult insects.

The locust hazard has a long history, over the years people have also summarized a lot of prevention and control experience, so, do not panic when you find the locust hazard, first control the number of occurrences, as long as the occurrence is not large, then the harm is not so strong, only need to do a good job of prevention and control drugs and later extermination drugs can solve the locust hazard.

The most harmful period for locusts is during the season when they reproduce and adults fly, which usually occurs during the season when the temperature is right, food is plentiful, and humidity is high. The exact timing varies greatly depending on the region and climate, for example, in the African savannah, locust plagues occur during the dry season each year.

The best time to eradicate locusts is during the few hatching and larval stages when they are few, because the number of locusts is relatively small and easy to control and exterminate. In addition, taking precautions before the adult flight season, such as using pesticides rationally and clearing weeds in the field, can also effectively reduce the damage of locusts.

Locusts have a certain necessity and role in the ecosystem. Although they are often seen as pests of crops, locusts also play a role in nature, affecting the ecological balance and species diversity. Here are some of the necessities for the presence of locusts:

1.A link in the food chain: Locusts are important food for many animals**, including birds, reptiles, mammals, and insects. They act as a link in the food chain, providing energy and nutrients to other animals.

2.Invasive plant control: Locusts feed on plants and can control the growth and spread of invasive plants at a certain level. In some desert areas and grasslands, locusts are able to prevent the overgrowth of certain plants and maintain ecological balance.

3.Soil fertility: During the feeding process, locusts ingest large amounts of plant matter and excrete it as feces. These manures are rich in nutrients that enrich the soil and help maintain the fertility of the soil.

4.Population regulation: Fluctuations in locust populations can naturally regulate their populations. Locust populations may increase when environmental conditions are suitable, but when food resources are reduced or other natural factors occur, populations can decline accordingly.

It is important to note that locust populations and behaviour are influenced by a variety of factors, including climate, temperature, food**, and habitat conditions. In some cases, when locusts are overfrequent, they can have a serious impact on agriculture and human life, and measures are needed to control them. However, understanding the ecological role and ecological function of locusts can help us better manage our relationship with locusts and seek reasonable solutions.
