Are there locusts in China s economic entomology?

Among the 55 volumes of the published "Insects of China", Orthoptera has not been involved.

<> locusts are insects. Locusts are locusts, arthropods, orthoptera, there are more than 10,000 species in the world, more than 1,000 species in China, distributed in the world's tropical, temperate grasslands and desert areas. In China, the East Asian locust has the widest distribution range and the most serious damage, and is the most important species of locust causing the locust plague in China, mainly harming gramineous plants and is an agricultural pest.

<> locust disaster is easy to occur in the hot season, generally locusts are more likely to occur in forests, low-lying long grasslands and other areas, the adults of locusts mainly feed on crops, and the locusts are more nutritious in the adult stage, and a large amount of food is needed to meet the development and growth of adults, which will cause major economic losses in agriculture, forestry and animal husbandry, and locusts do not have the habit of clustering and migration, and are generally scattered in the fields and grass.

First, locusts are easy to occur

1. Locust plagues are more likely to occur when the weather is hot and dry, especially when dry weather comes, locust plagues are easy to occur, and locusts are generally more likely to occur in forests, low-lying long grasslands and other areas. The arid environment has many benefits for locusts to reproduce, grow and develop, and locusts can lay their eggs in the soil because the soil is relatively solid and the water content is 10%-20% more suitable for locust eggs.

2. Adults mainly feed on crops, and locusts supplement more nutrients in the adult stage, they bite a large number of plant leaves and flower buds with chewing mouthparts, resulting in gaps and holes, and in serious cases, they will eat up the leaves and flower buds of large areas of plants, resulting in major economic losses in agriculture, forestry and animal husbandry.

3. Locusts do not have the habit of swarming and migrating, they often live in one place, generally scattered in the fields and grasses, and the locusts mainly eat grasses, so they will also have certain harm to rice and legume crops.

2. How to prevent locusts

1. When the locust disaster comes, you can reduce the planting of rice, barley, corn, etc., which locusts like to eat, and change it to fruit trees, etc., and the locusts will not eat the food that is more difficult to eat, but this fundamentally cannot prevent and control locusts.

2. The control of locusts can also be solved from the natural enemy, when the locusts come, they can herd chickens and ducks into the farmland, and they can also be stocked with bees, frogs, lizards, etc.

3. Locusts also have a favorite place to live, they generally like to live in low-lying long grasslands, when locusts come, they can transform low-lying areas into fish ponds and pond landscapes to control locusts.

4. There are many chemical control methods, one is spraying on the ground, such as drone application; Or spray pyrethroid oils, both of which can effectively solve the locust plague.

Locusts are pests and love to eat crops.

Locusts are herbivorous insects, including plant parts and fruit decay.

Locusts are found in tropical, temperate grasslands and deserts around the world. It feeds mainly on the branches and leaves of plants. The lifespan is generally about 2 to 3 months.

They bite the leaves and buds of plants with chewing mouthparts into gaps and holes, and in serious cases, they eat up the leaves and buds of large areas of plants, causing major economic losses in agriculture, forestry and animal husbandry.

Some species are oligophagous pests, such as the East Asian locust, which feeds only on grasses and sedges; Some species are polyphagous, such as the Giant Cushion Locust. When the season is dry, they are more voracious, excreting large amounts of food from their bodies without adequate digestion in order to obtain a large amount of water from it.

Yes, locusts.

It's an insect, and it's a typical insect.

Locusts are commonly known as "grasshoppers, belonging to the class Insecta."

There are more than 10,000 species in the world of Orthoptera and Locusts, including all species of grasshoppers, grasshoppers, and locusts.

Locusts are incomplete metamorphosis insects, including eggs, nymphs, and adults.

In the case of adult locusts, their bodies are divided into three parts: head, thorax, and abdomen, with a pair of antennae and a pair of compound eyes on the head; thorax with two pairs of wings and three pairs of feet; The abdomen is segmented with valves for breathing on both sides of each segment. These characteristics are typical of insects. So, locusts are insects.
