Desert locusts may be at risk of invading China, and the authorities issued an emergency prevention and control notice.

Recently, the desert locust plague originating from East Africa has become one of the hot spots of concern in all walks of life. Due to poor initial control, it has spread to India and Pakistan.

Faced with the menacing desert locust, many people are worried about whether it will invade our country. On February 16, the Ministry of Agriculture and Rural Affairs responded that considering the topography, climate characteristics and migration habits of desert locusts in China's border areas, it is unlikely that desert locusts will harm China.

Faced with the menacing desert locust, many people are worried about whether it will invade our country. On February 16, the Ministry of Agriculture and Rural Affairs responded that considering the topography, climate characteristics and migration habits of desert locusts in China's border areas, the probability of desert locusts harming China is very small.

Recently, however, the State Forestry Administration issued an urgent notice that desert locusts may be at risk of invading China. What exactly is it? Let's have a look.

What is the risk of desert locusts invading China?

According to the notice, experts judge that if the climatic conditions are suitable, there is a greater risk that desert locusts will invade Tibet directly from Pakistan and India, or Yunnan through Myanmar, or Xinjiang through Kazakhstan.

The border areas of Xizang Autonomous Region, Pakistan, India and Nepal in China are desert locust spreading areas, but due to the limitations of environment, climate and food, it poses little threat to China's agricultural production.

Due to the barrier of the Qinghai-Tibet Plateau, it is extremely unlikely to move directly to the inland areas of China.

In addition, even if we enter the border provinces of China, it is difficult to continue to invade the inland areas of China and cause harm.

However, in the year when desert locusts occur seriously, locusts will spread from India to Bangladesh and Myanmar from south to east.

If it spreads to this area, the risk of moving into southern Yunnan will increase greatly.

Have desert locusts ever invaded China in history?

The plague of locusts in the history of China was recorded as early as the Spring and Autumn Period.

According to the statistics of entomologist Guo Yue, during the two thousand years from the Spring and Autumn Period to 1949, there were more than 800 locust plagues in China, and there was a large-scale outbreak every 5-7 years.

Due to the uneven preservation of historical materials of locust plague in different dynasties, the simpler it is, the more actual disasters should be.

However, with the progress of scientific control technology, locust control in China is very effective now. We are committed to researching the "3S" technologies used for monitoring, namely, remote sensing technology (RS) subsystem, geographic information system (GIS) subsystem and global navigation and positioning system (GPS) subsystem, and using a series of new biological agents to develop green locust control technology, which has initially achieved the goal of "locusts not taking off, locusts not spreading, and locusts moving twice".

We still have reason to believe that desert locusts are "preventable and controllable".

How should China deal with this risk? See what the official says.

Earlier, the China locust control team had arrived in Karachi to help it fight the locust plague.

In addition to putting forward the "four in one" plan, it also refutes the statement that "Zhejiang 65438+ Wanya Army aided Pakistan", and the Duck Corps has not yet gone to Batie.

On March 2nd, China Forestry Network official website issued a statement saying that according to FAO's analysis, the large-scale locust plague that started in Africa was affected by many factors, and many prevention and control measures were not timely, which may last until June 2020.

In view of this situation, officials of China National Forestry and Grassland Administration also issued a warning and gave four preventive measures, including earnestly performing their duties and fully understanding the extreme importance of doing a good job in locust control; Strengthen monitoring to keep abreast of the international and domestic desert locust disaster dynamics; Improve the emergency plan and strive to build a long-term mechanism for grassland locust disaster prevention and control; And strengthen the implementation of measures to do a good job in the prevention and control of grassland locust disasters in 2020.

In addition, to strengthen the understanding of locust control, all departments should also strengthen the detection of locusts and grasp the latest trends of locust disasters.

Of course, it is also indispensable to strengthen and improve the implementation of emergency plans.

Generally speaking, the desert locust plague in East Africa may not pose a threat to China, but experts speculate that there are also desert locusts in Yunnan and Tibet, which should not be taken lightly.

All departments should actively prepare for emergency prevention and control, prevent locust plague and ensure food security.
