Can ducks kill locusts? How to kill locusts quickly?

In ancient times, locusts, floods, and fires were called the three major natural disasters, but recently, when China was in the midst of the Anti-Japanese War, locusts had crossed the Red Sea into Europe and Asia, and reached Pakistan and India, which was only one step away from our country. so some areas began to use ducks to kill locusts, can ducks kill locusts? How to kill locusts quickly?

Can ducks kill locusts?

A duck can kill locusts. According to Xinhua News Agency in June 2001, citing media reports in 2000, Zhejiang "sent" 30,000 ducks to Xinjiang by plane to eat locusts.

According to the parties concerned, ducks have a strong ability to catch locusts, have a large amount of prey, and the "army" is Yanming, and dispatching ducks is the most effective way to eliminate locusts and protect the ecology in the grasslands. The ducks eat twice a day. At four or five o'clock in the morning, as soon as it is dawn, the ducks go out by themselves to eat locusts. A few hours later, they go to the nearby creek to drink water and have a rest. The ducks set out again at more than 7 p.m., and didn't come back until more than 9 p.m. A duck can eat more than 100 locusts in one breath.

Second, how to kill locusts quickly?

With regard to the prevention and control of locusts, we should adhere to the plant protection policy of giving priority to prevention and comprehensive control. The number of locusts can be effectively controlled by doing a good job of agricultural control in the early stage and appropriate pesticides and biological control in the later stage. The specific methods are as follows:

1. For the fields prone to locusts, it is suggested that growers should do a good job in daily management, plough the land in time after planting, make the eggs exposed to the air, and kill the eggs by low temperature sunlight; in addition, do a good job of water management in the field, in dry years, appropriate watering can inhibit the hatching and growth of locusts.

2. Chemical control and chemical control are the most effective ways to control the number of locusts. In the early days of locusts, growers can use plant protection equipment such as sprayers and drones to spray on possible areas. Locust control agents can choose 10% cis-cypermethrin 1500 times, 40% bifenthrin. 2000 times thiacloprid and 6% avermectin. Beta-cypermethrin 750 times equal spray.

3. Biological control. The use of pesticides is easy to destroy the ecological balance, so in the past two years, many people have suggested the use of biological control methods to control locusts. At present, the more mature biological control methods are:

The main results are as follows: (1) the method of grazing chickens and ducks is more mature in the grasslands of northwest China. Chickens and ducks feed on locusts and can control the number of locusts. At the same time, chickens and ducks can not only lay eggs, but also better meat, creating additional benefits for herdsmen.

(2) Bird control. In Xizang area, some pastoral areas have realized the biological control of locusts by building bird nests and absorbing pink starlings.

(3) the control of microsporidia can parasitize in locusts and feed on locusts, which can achieve insecticidal effect without harming the environment.
