Why are locusts pests? What are the dangers of locusts?

Locusts have the habit of making food with locusts in the whole world, the flesh of locusts is soft, delicious as shrimp, major hotels, restaurants fried and fried to make "fried grasshoppers, land flying shrimp, flying locusts Tengda" and other dishes are favored by consumers, and such as Mexico in recent years, published a booklet called "Eat Insects", at the end of the book lists more than 40 kinds of insect dishes processing recipes, the first example of which is called "Chinese style" "peanut fried locust shrimp" according to the insect recipe collection "green onion fried locust" Put clear oil or lard into the pot, fry the fresh onion slices, then add the washed locusts and fry for a while, then add edible spices (such as five-spice powder, cinnamon powder), garlic, chili powder, etc., and then spray a little water and mix well. When cooked, the locusts are stir-fried with green onions as the sandwich of bread to become a locust sandwich. <>

The damage of locusts isEating crops and leaving insect eggs to cause secondary damage and make it difficult for crops to recover.

1. Nibble on crops

Locusts are more terrifying for the gnawing of crops, and their gnawing is not like other pests, they will gnaw directly to the root system, which means that there will be basically no residue above the soil layer. Vegetables are generally relatively tender, and only the main branches are left that can be gnawed by trees, so vegetables basically can't leave anything.

2. Eggs left behind cause secondary damage

In order to survive after the locust plague is formed, the locusts will spread to the surrounding area, and during this time, they will basically eat constantly. As they spread to the surrounding areas, they lay eggs in various places and continue to spread their populations, which is why the plague of locusts grows larger and larger.

When the locusts have enough food, their reproductive efficiency is very terrible, and the small locusts grow up quickly, and the slow hatching of these eggs will cause secondary damage.

3. It makes it difficult to recover crops

This does have a great impact on growers, and the land left after the locust plague basically has no good plants, and basically only the root system remains.

For orchard growers, these fruit trees are basically half wasted, I don't know how long it will take to recover, for vegetable growers, it is necessary to prepare for replanting, which takes a long time, the investment is wasted, and we have to prepare new funds to recover, which is even more difficult.

Locusts are an important part of agricultural, forestry and animal husbandry ecosystems, and many harmful locust species can cause varying degrees of harm to agriculture, forestry and animal husbandry.

There are more than 1,000 species of locusts known in China, of which about 60 species can cause harm to agriculture, forestry and animal husbandry. The species that harm legumes, potatoes, sweet potatoes and other crops include short-winged locusts and benzene locusts. Cotton locusts and negative locusts can harm cotton. Bamboo locusts can seriously harm bamboo forests.

When it occurs, it can seriously harm pasture and crops and directly affect the development of agriculture and animal husbandry. According to the records of China's historical books for thousands of years, the locusts that cause devastating disasters in agriculture are mainly flying locusts, and it is believed that drought has the greatest chance rate or correlation with the occurrence of flying locusts in the same year, followed by drought in the previous year and first flooding and then drought, grasshoppers in patches.
