Fall armyworm has invaded our country! What measures has China taken to deal with it?

For the large-scale invasion of fall armyworm into China's territory, China has taken a high degree of attention and made important instructions for agricultural supervisors at all levels. After the instructions were issued, China's agricultural scientific and technological personnel made a plan to deal with the invasion of the large population of fall armyworm, and according to the living habits of fall armyworm and the impact of some drugs on fall armyworm, China made tough measures for the large-scale attack of fall armyworm. <>

Fall armyworm is much more powerful than locusts because it eats crops faster than locusts and migrates more than twice as fast as locusts. In addition, due to its long-term struggle with people, its resistance has also increased greatly while evolving, and it can be said that it is also a very difficult battle in the face of fall armyworm. Fall armyworm reproduces very quickly, faster than locusts, so it is important to start from the beginning.

If Fall Armyworm really invades China's territory on a large scale, China will definitely take tough measuresFire attacks may be used, or large-scale pesticide spreading may be used to destroy the breeding eggs of fall armyworm. Moreover, during the locust plague, people also took certain corresponding measures. **At that time, when faced with the invasion of locusts in the senior year, people were asked to catch locusts and be rewarded accordingly.

Therefore, if the fall armyworm really invades China on a large scale, it may also take such a measure. <>

Now the top level personnel have been deeply concerned about this matter, and various local institutions have taken corresponding measures, in the face of the fall armyworm invasion of China, they have also made a perfect strategy, not only scientific researchers in the fall armyworm living habits to make research, but also to find the weakness of fall armyworm. I think that if fall armyworm does invade China, the best way to eliminate this pest is to spray pesticides or use fire to eradicate these pests

Fall armyworm is a seed player that harms crops and causes great damage, so in order to protect the environment, China uses biological treatment methods and uses parasitic wasps for treatment.

At present, China has adopted a comprehensive monitoring policy in places where fall armyworm is infested, and released insecticides in targeted and dosed areas to eradicate pests!

One is to improve the plan and distribute it to all localities, the second is to strengthen early warning, prevent re-proliferation and cause unnecessary consequences, and finally prepare sufficient funds for prevention and control to prevent and control before it happens.

Regarding fall armyworm, the CCP issued a document related to agricultural land. It is necessary to do a good job in the prevention and control of major pests and diseases such as fall armyworm. At present, the Ministry of Finance has allocated 1.4 billion yuan in agricultural production and water conservancy disaster relief funds to support the prevention and control of major crop diseases and pests, including 100 million yuan for the prevention and control of fall armyworm.

It is used to do a good job in the prevention and control of fall armyworm. Practical medicines were also recommended to farmers. Many, many measures have been taken to deal with it.

China has formulated a contingency plan, determined regional targets, carried out comprehensive monitoring, all-out culling, implemented regional policies, joint prevention and control, optimized monitoring, prevention and control measures, vigorously promoted unified prevention and control and emergency prevention and control, combined with biological and ecological control.

1. Fall armyworm is a polyphagous pest, native to the Americas, for food edible corn, sorghum, wheat, rice, etc., in the long-term evolution process of differentiation into two ecological types, according to the different feeding host plants are divided into "corn type" and "rice type", the former is hungry for corn and sorghum, and the latter is hungry for rice and pasture. In 2019, the invasion of China was mainly for "corn-type celery".

2. In view of the significant biological advantages of fall armyworm such as wide suitable area, wide host range, strong proliferation potential, fast diffusion speed, and heavy sudden damage, once the insect pest occurs, it will have a very extensive and serious impact on the crops of our country, especially the grain crop corn, especially the young corn plants are more favored.

As a migratory pest, fall armyworm has the following characteristics: a large source base, early northward migration, and an expanded area. In addition, it has been colonized in southern China, and at the same time, foreign insect sources continue to move in, and the situation in 2020 will be more severe, and the prevention and control task will be more arduous and more complex than in 2019.

The continuous migration of foreign insect sources and the growth of local insect sources in 2020 will lead to the population population far exceeding that of the northward migration insect source in 2019. In addition, the spring of 2020 will be about a month earlier than in 2019, and correspondingly, it will spread to the Huang-Huai-Hai region and the northeast region earlier, which is the seedling stage of summer corn in the Huang-Huai-Hai region and the new leaf stage of spring corn in the north, so the damage is expected to be greater than in 2019.

Spodoptera exigua will have translucent membrane "intestinal holes" and irregular pores on the corn leaves, or they will eat up the whole corn leaves, and in severe cases, the corn growing point may die. This kind of pest eats a large amount, especially at an advanced age, so even if it eats a plot, it will migrate to the surrounding crop fields in groups, continue to suffer, and the loss is particularly serious. The reason why the spodoptera exigua, which is very harmful:

High fecundityThe meadow noctuidae is very fecund, and under normal circumstances, a female moth can lay up to nearly 2,000 eggs. In addition, the grassland is also very strong in the growth of noctuidae and can survive normally in various environments. And it can also be parasitic, and the parasitic range is also wide.

It can be parasitic not only on corn, but also on food crops such as rice and millet. Weeds can also grow, and when it is most important, they have the ability to fly, and they spread very quickly, and the affected area expands.

There are antibodies to various pesticides, and the control effect of various pyrethroid pesticides is not obvious. Moreover, because the grassland poison moth is an alien species in our country, our country has no natural enemies, so it grows quickly. And the meadow gluttony armyworm is a pest of the Americas, so it is very common on corn.

Therefore, local residents often use pesticides, which naturally produce large amounts of antibodies to noctuidae in the meadows. Therefore, after invading our country, many pesticides naturally lose their effectiveness by carrying antibodies themselves. Spodoptera exigua's prevention** method on the grass.

The grassland moth is an invasive species, so at present, China cannot place effective pesticides. However, in the natural grassland, after the outbreak of the disease of the noctuidae, all parts of our country have entered the emergency prevention work. Agricultural parks are also screening common pesticides in China, first of all, from these pesticides to select pesticides with good prevention effect and low toxicity.

To a certain extent, it can prevent grassland poison moths, inhibit reproduction, and reduce the number. Avoid causing more damage. Strong fecundity.

Tolerance of the large grassland moth has antibodies to various pesticides, and the control effect of various pyrethroid pesticides is not obvious. Moreover, because the grassland poison moth is an alien species in our country, our country has no natural enemies, so it grows quickly. And the meadow gluttony armyworm is a pest of the Americas, so it is very common on corn.

Therefore, local residents often use pesticides, which naturally produce large amounts of antibodies to noctuidae in the meadows. Therefore, after invading our country, many pesticides naturally lose their effectiveness by carrying antibodies themselves. Spodoptera exigua's prevention** method on the grass.

However, in the natural grassland, after the outbreak of the disease of the noctuidae, all parts of our country have entered the emergency prevention work. Agricultural parks are also screening common pesticides in China, first of all, from these pesticides to select pesticides with good prevention effect and low toxicity.

To a certain extent, it can prevent grassland poison moths, inhibit reproduction, and reduce the number. Avoid causing more damage.

Fall armyworm can be controlled according to the lepidopteran pest control program, such as chlorantraniliprole, cyantraniliprole, and fiproramide, and it is recommended to mix it with flufluthrin, methrin and other agents.

If the corn plant is harmed, the corn leaves will appear translucent film holes and irregular long holes, and the fall armyworm eats a large amount, and after eating up the crops in one area, it will migrate to other crop areas in groups to continue to harm, seriously endangering the growth of crops. For the adults of fall armyworm, they can be used to trap and kill them with insecticidal lamps in the affected areas during the adult occurrence period, or combine sex attractants and food attractants to enhance the control effect.

Because fall armyworm is an invasive species, there is no effective pesticide to control it in China. However, after the outbreak of fall armyworm in nature, all parts of our country have entered the emergency prevention and control work. The Academy of Agricultural Sciences is also screening common pesticides in China, first picking out pesticides with good control effect and low toxicity from these pesticides.

It can control fall armyworm to a certain extent, inhibit reproduction and reduce the number. Avoid causing greater harm.

Fall armyworm is a moth of the genus Spodoptera exigua, native to tropical regions of the Americas and has a strong migratory ability. The life span of the adult is about 12 days, and the complete cycle is only 30 days, and its larvae can eat a large number of crops such as grasses such as rice, sugarcane and corn, as well as Asteraceae and cruciferae, causing serious economic losses.

For the invasion of fall armyworm, many corn-stricken areas in southern China have given corresponding countermeasures, and the following prevention and control measures can be taken.

First, monitoring and early warning.

Key monitoring points were set up in the planting areas of high-risk crops such as corn, rice and potato, and the number and dynamics of adult Spodoptera frugiperda were monitored by using black lights, tuopu high-altitude detection lights, and sex pheromone trapping. In the occurrence area, the method of combining field census and systematic investigation can be used to accurately grasp the number of eggs, larvae and pupae of fall armyworm, the degree of damage and their dynamics, and release early warning information in a timely manner, so as to achieve early detection, early reporting and early warning.

The second is adult trapping.

During the occurrence of adult worms, insecticidal lamps are used to trap and kill them in concentrated and continuous pieces, and the control effect can be improved with sexual attractants and food attractants.

The third is larval control.

Chemical control is the most effective measure for the control of fall armyworm larvae at present, seize the best period of young larval control, and the best application time is to choose early morning or evening, and pay attention to spraying on corn heart leaves and ears.

Hello, fall armyworm is a serious invasive insect that has been harmed across the country for 2 consecutive years, seriously threatening the safety of food production. To study the morphological characteristics, hazard characteristics, ecological regulation, physical and chemical trapping and control, biological control and scientific use of Fall Armyworm, and summarize the green prevention and control technologies in order to provide a theoretical basis for the systematic study of Fall Armyworm, and to provide a reference for further integration of the green prevention and control technology model of Fall Armyworm. <>

I don't think it will spread, and my country's experience in pest control is still very sufficientAlthough the fall armyworm is more powerful than the locust, it is an insect that can be eliminated in various ways.

No, because our country has attracted a high level of attention and vigorously culled the fall armyworm, so it will not spread.

If fall armyworm invades our country, then it will not spread in our country, because we have treated such insect plagues in the early years, so we are still very experienced in this area.

Animals such as bullfrogs and Brazilian tortoises are exotic species, but in our country because of the blind release of some people

In fact, China has also suffered from the serious invasion of many alien species, such as water hyacinth living in the water, and the aircraft grass in Xishuangbanna, because they have no natural enemies in China, so they are growing wildly.

The alien species that we have also suffered from are: Aedes albopictus, Brazilian red-eared turtle, water hyacinth, ragweed, etc., these are all these.

Aedes albopictus, Brazilian red-eared turtle, water hyacinth, etc. For example, the water hyacinth is native to Brazil and has a very strong reproductive ability, and now a large number of reproduction in the Yangtze River and other river basins will consume dissolved oxygen in the water, causing a large number of fish to die.
