CATDOLL : CATDOLL: What does a locust look like? What are its living habits?

1. The appearance is:

It has hard mouthparts, narrow and tough front wings covering the hind wings, which are thin and suitable for flying, and well-developed hind limbs, making it good at jumping. It mainly harms grass plants and is an agricultural pest.

Locusts have well-developed hind legs, and can use them to jump distances several dozen times longer than their bodies. They are incompletely metamorphosed insects, and their larvae and adults are similar, with the only difference being the presence or absence of wings. The hind wings are translucent. The wings of some species of locusts have degenerated and become smaller, and some species, such as the diamond locust, have lost the ability to fly.

The body color is green or brown, regardless of the species; it is a protective color for the living environment. Locusts have large mouths and well-developed jaws, and feed on plant leaves. Locusts like to eat reeds, barnyard grass, white grass, sedge and wormwood, shrimp grass and sea salicornia. Some locust species are omnivorous and also eat dead insects, even the dead bodies of their own kind.

2. Habits

1. Food habits and ways of feeding and causing harm

Adults have the same diet as locust nymphs, both are herbivorous, and they need to supplement their nutrition strongly during the adult stage, accounting for more than 75% of their total food intake in their lifetime. They chew plant leaves and flower buds with their chewing mouthparts, leaving notches and holes. In severe cases, they will eat up the leaves and flower buds of large areas of plants, causing significant economic losses to agriculture, forestry and animal husbandry.

Some species are oligophagous pests, such as the East Asian migratory locust, which only feeds on plants of the Gramineae and Cyperaceae families; some species are polyphagous, such as the large-winged grasshopper. When the season is dry, they are more greedy and excrete a large amount of food without fully digesting it in order to obtain a large amount of water from it to meet physiological metabolic needs, thereby increasing the degree of damage to crops.

2. Activity habits

Both adults and locust nymphs hide at night and come out during the day, and have no obvious phototaxis.

When the density of locust nymphs is high, they form conditioned reflexes due to mutual sensation, intensify their activities, and are prone to form groups, lie dormant, and crowd together, and then jump and migrate in a certain direction.

3. Egg-laying habits

The pre-oviposition period of adults is relatively long, generally 10 to 30 days, with multiple matings and egg laying in batches. Female adults lay eggs in clusters under the soil.

1. Research value

Locusts are a worldwide agricultural pest. Their damage is characterized by periodic population explosions and long-distance migration. Years of research have shown that the transformation of locusts from scattered individuals to individuals who prefer to live in groups is the biological basis for locusts to form large-scale groups, migrate long distances, and cause disasters.

In recent years, the understanding of the mechanism of locust metamorphosis has been continuously deepened. In particular, in terms of the molecular regulatory mechanism of migratory locust metamorphosis, the research group of Kang Le, a researcher at the Institute of Zoology, Chinese Academy of Sciences, has used genomics, metabolomics, bioinformatics and gene manipulation since 2004 to reveal the molecular mechanism of behavioral regulation in migratory locust metamorphosis and outline the molecular regulatory network that regulates locust metamorphosis.

Understanding the mechanisms of transition between solitary and gregarious locusts will help develop new strategies and methods for sustainable management of locust plagues.

2. Therapeutic value

With the development of society and the continuous improvement of the quality of life, the human table has shifted from traditional types such as chicken, duck, fish and meat to green game. Locusts are rich in nutrients, tender in meat, and taste as delicious as shrimps. In Hong Kong and other places, they are known as "flying shrimps" and are a delicacy loved by people from all countries. In the United States, "insect banquets" are held to entertain guests, which include locusts.

Insect food has become popular in some countries and regions. Insects are used to cook dishes, or made into canned food, biscuits, ice cream and other foods, which are very popular.

The body of the Chinese rice locust, migratory locust and other insects of the family Acrididae. Also known as grasshoppers. Distributed in North China, East China, Central and South China, Sichuan, Shaanxi, Gansu, Taiwan and other regions. After obtaining, remove the wings and legs, wash, and scald to death with boiling water before eating. It contains high protein and is the most ideal food.

Locusts are insects of the family Acrididae and the order Orthoptera. Commonly known as "grasshoppers", there are many species, with more than 10,000 species worldwide. They are distributed in tropical and temperate grasslands and deserts around the world. They have hard mouthparts, narrow and tough forewings that cover the hind wings, which are very thin and suitable for flying. Their hind limbs are well developed and they are good at jumping. They mainly harm plants in the Gramineae family and are agricultural pests.

Locusts are extremely numerous and have strong vitality, and can live in a variety of places. They are most common in mountainous areas, forests, low-lying areas, semi-arid areas, and grasslands.

Most of them are important pests of crops. They may break out in large numbers during severe droughts, causing disasters to nature and humans.

The larvae can only jump, while the adults can fly and jump. They mostly feed on plants.

The grasshoppers that people often talk about (in a few places, they are all called grasshoppers regardless of size) are just the larvae of locusts, not a separate species.

There is another common insect, grasshopper, also known as grasshopper, also known as grasshopper in northern China, belongs to invertebrate, Insecta, Orthoptera, Acrididae, Tetrigoidea. Commonly known as pole hook, it is often confused with locust larvae.

Herbivorous. They like to eat thick leaves, such as sweet potatoes, water spinach, cabbage, etc.

Developmental period 2

Every summer and autumn is the breeding season. After mating, the female locust inserts the ovipositor into the soil 10 cm deep and lays about 50 eggs. When laying eggs, the female will secrete a white substance to form a cylindrical plug, and then lay the eggs.
