The destruction of hundreds of billions of locusts? Army? All the way from East Africa to Pakistan in South Asia. At this time, the locust plague brought immeasurable economic losses to agriculture in many countries and regions, but fortunately, this locust army has been controlled in India. Even so, affected by the monsoon, a large number of locusts have arrived in Pakistan. Therefore, many experts put forward that killing locusts with ducks can help Pakistan. Because Pakistan, after all, belongs to China's neighboring country, if the method is feasible, the locust plague can be completely controlled.

Is it reliable for ducks to cure locusts?

Is it reliable for ducks to cure locusts? The answer is yes. There were many locust plagues in ancient China. In ancient times when science and technology were backward, people didn't have pesticides and drones, so the containment of locust plague became a big problem. So, the wise ancients thought of a way to control locust plague with ducks, that is? Pasturing ducks and treating locusts? .

It is feasible to exterminate locusts by grazing ducks. After all, ducks are also a kind of birds. Birds mostly feed on insects, and locusts are common insects. So from the perspective of natural enemies, it is indeed possible to kill locusts with ducks.

Let's see what has happened in modern times. Pasturing ducks and treating locusts? An instance of. In May 2000, a locust plague broke out in northern Xinjiang, China. At this time, the plague of locusts was killed by ducks. 30,000 ducks flown in from Zhejiang joined the locust control army. These ducks are dispatched twice a day on average, and each duck can eat hundreds of locusts. In this way, every day, 30,000 ducks clear locusts within 1 10,000 mu of land. Three months later, 6,543,800 mu of land was cleared (of course, there were human factors).

It can be seen that ducks are reliable in treating locusts.

Limitations of duck grazing and locust control

It is feasible to control locust plague with ducks, but it also has great limitations. First of all, we can refer to the locust plague in Xinjiang more than 20 years ago. The plague of locusts occurred in the plain of northern Xinjiang. The terrain is not complicated, there are many grasslands, and locusts will fall on the grasslands to eat grass, which provides convenient conditions for ducks to eat locusts.

Secondly, using ducks to control locust plague must be in a small range. Let's take the locust plague in Xinjiang as an example. The plague of locusts only occurred in northern Xinjiang, which had limitations. However, the scale of locust plague at this time is rare for decades, and it takes three months for 30 thousand ducks to eliminate regional locusts. If this time is replaced by a plague of locusts, it will take a lot of time, and during this period, the losses will continue.

Finally, there are kinds of locusts. This time, the locust is a desert locust, which has strong flying ability and can move at a speed of 150 km per day. In this case, it is not conducive to using ducks to control locusts.

abstract

Curing locusts by herding ducks has existed since ancient times, and it is indeed an effective method to control locusts. However, due to the influence of topography, locust species and scale, this method is not suitable for locust plague in East Africa. With the development of science and technology today, it is obviously faster and more practical to spray crops with drugs with strong pertinence and low toxicity by drones.
