For example, Chen Shiyuan's "Biography of Controlling Locusts" and "Biography of Golden Potato" in the late Ming and early Qing Dynasties recorded the experience of releasing ducks to control locusts in Jiangnan area. In the Qing Dynasty, it was recorded in Lu Shiyi's "The Story of Eliminating Locusts":? The locusts were eaten by ducks before they could fly. Hundreds of ducks are like rice beds, and locusts are dried up instantly, which is also a way to catch locusts in Jiangnan. ? Qu Dajun of the Qing Dynasty pointed out in Xinyu, Guangdong, that ducks can? Eat cockroaches (a small crab) in spring and summer and rice in autumn? .
During the Republic of China, this method was still popular in Jiangnan area. For example, the people of Nanjing, Jiangsu Province spontaneously organized in July 1936? Baguazhou locust breeding society? . Baguazhou, located by the river, is a concentrated place for locusts to lay eggs. Most of the locust larvae grow here, which greatly affects the local agricultural life.
1937 "Agricultural News" published an article "Raising ducks to control locusts", which introduced in detail the specific situation of using ducks to control locust disasters. The article says that ducks can be raised four times a year in the local area, about 800 ducks. A duck can eat about 2 kilograms of locusts (locust larvae) every day, and it can make a profit 100 yuan a year after it is sold. At that time, an egg was almost fifty cents. This? Baguazhou locust breeding society? It is stipulated that the funds for raising ducks should be raised by local tenants every mu, and every hundred mu 10 ducks. Part of the income is used as the fixed expenses of the association, the remaining 60% is distributed to farmers per mu, and 40% is used as a reserve fund for preventing and controlling locust disasters.
Such measures are good for farmers and locust control, but we should not take this case too simply and the method of raising ducks to control locusts too high.
First of all, this method is extremely difficult to popularize.
From the case of the Republic of China, we can know that chickens and ducks are more suitable to control locusts in economically developed areas. Farmers have spare money and a sense of cooperation, and they can jointly invest in sideline business, but it is very difficult to operate in some economically backward areas.
Moreover, ducks kill the larvae and eggs of locusts, which has little effect on overwhelming adults. An adult East Asian locust is about three to five centimeters. Desert locusts in East Africa and South Asia are slightly larger than East Asian locusts, generally 4-6 cm. After the locust crosses the border, nothing grows, whether it is crops, livestock or even human beings, it will become his goal.
"Luanchuan Literature and History Materials" records an old man's memory of the real scene of the locust plague in 1942. He said: There is a foreigner named Shen in Daqinggou Village Street? Unable to walk because of illness, I wanted to rest on the side of the road before walking, so I was surrounded by grasshoppers. Pity him for struggling and being bitten to death by grasshoppers. The meat on my body was eaten clean and became a skeleton. ?
I would like to ask, if100000 ducks are given to adult locusts, what is the control effect of locusts? Or send meat to locusts?

Secondly, controlling locust plague is a regional systematic project.
During the Republic of China, there were 2 100 locust plagues in counties, especially in Shandong and Hebei, each lasting for 2~3 years, especially in 1927 ~ 1928. Shandong Province was completely affected, which can be described as famine everywhere. During the Republic of China, most of the victims were at a loss because of personnel corruption, internal and external troubles, not to mention the money raised by Nanjing farmers mentioned above. Duck club? Come, even the water conservancy facilities are mostly abandoned.
So, ordinary people can only ask? Witchcraft? Ask for help. After the plague of locusts, ordinary people rushed to offer sacrifices to General Liu Meng, the god of locusts, and all the seemingly useful temples. Master Cao Meng? Singer, for? Master Cao Meng? People who kill pigs have all kinds of stupid behaviors. The victims usually regard locust plague as a natural punishment, but they regard locust as an incurable insect. Even some staff who go to places for scientific guidance will be stopped by ignorant villagers. Do you have it now? If three grasshoppers dare not jump together, they will be blown into a string? This statement did not hold water during the Republic of China.
The plague of locusts does not care about artificially divided administrative regions, but must be coordinated between regions and the whole country. Therefore, the control of locust plague cannot rely on the spontaneous behavior of some people, but must rely on a unified government for unified dispatch and command.
The way of raising ducks to control locusts can only be used as a small-scale regional behavior. Its purpose is to prevent more than cure, and its effect is quite limited.
During the period of the Republic of China, the warlord regime and the internal struggle among political parties prevented local governments from organizing a unified national strategy to control locusts, which made the locust plague in the Republic of China more serious than that in the Qing Dynasty and greatly affected people's health, production and life.
Disaster relief victims in the Republic of China often get only a few cents in aid.
The working people in China seem to have endless ways to deal with the plague of locusts. These concrete measures are often laughed at, and even romantic fantasies are normal. However, in the decades after the founding of New China, the plague of locusts was still completely eradicated. Only through the continuous efforts of generations of experts, scholars and people, it faded out of people's field of vision under today's scientific modernization measures. What do these look like? Interesting? The solution can not completely solve the people's sufferings before the founding of New China, nor can it completely solve the locust plague in East Africa.
The control of locust plague is also the touchstone to test the basic governance and management ability of a modern country. According to the experience of the Republic of China, it is not feasible to control locust plague with chickens and ducks. This plague of locusts can only be cured through international cooperation and mobilization of people in East Africa and South Asia. At present, most of these areas are developing countries, and even some countries are in turmoil and have conflicts with their neighbors. This disaster is not optimistic.
