I want to know the market prospects of wild locusts. Where are the main consumption areas? In addition to human consumption, what valuable products can be developed?

Things to note when raising locusts

1. Selection and identification of locust breeding sources

(1) Consult locust taxonomy experts.

(2) Consult a locust key table or atlas.

(3) Consult experienced locust farmers.

(4) Send locust species to customers for identification and review.

Common types of farmed locusts include: East Asian migratory locust, cotton locust, Chinese rice locust, Chinese grasshopper, etc. These varieties have their own advantages and disadvantages. It is necessary to comprehensively consider factors such as their growth cycle, generation, taste, food, size, and the variety required by the customer, and select the breeding variety in combination with the local climate, food source, etc.

2. Construction of locust breeding shed and preparation of shed land

Before building the shed, first eliminate all ants and mole crickets on the ground. You can use methods such as capture, trapping, and scalding. The above insects are natural enemies of locusts and can prey on locusts and destroy locust eggs, so these animals must not be allowed to exist in the shed. In order to facilitate drainage in the rainy season, the floor of the shed should be 10-15 cm above the ground. The soil should preferably be sandy loam, which is not easy to clump and is convenient for laying eggs. In mid-April, you can plant crops such as wheat on the ground where the shed is built to prepare for the young locusts to eat.

The construction area of ​​the shed is determined by the number of locusts to be raised. If you want to raise 10,000 locusts, 15 square meters is enough. You can use the free space inside and outside the yard to build a shed frame with wire, sticks, bamboo strips, etc. according to your own conditions. Then, according to the size of the shed, use ribbed cloth (gauze cloth) to make a shed cover like a mosquito net, hang it on the shed, bury the bottom edge in the ground, leave a door, and install a zipper on the door. This device is to prevent the locusts from running out and facilitate feeding and management. (It can also be built into an arched shed)

The height of the shed can be 1.5-2 meters. In order to keep warm and prevent rain, plastic sheets can be covered outside the shed. When the temperature is high and the locusts are large (older) and not afraid of rain, plastic sheets can be omitted. If locusts are raised under natural conditions, the construction of the shed must be completed before the end of April, and a sunny place is preferred.

3. Nymph stage management

⑴ Locust nymphs eat very little and prefer to feed on fresh and tender plants. At this stage, locusts are very fragile, so you should pay attention to rain protection to prevent them from drowning.

⑵The temperature should be controlled at 25-30℃, the light should be more than 12 hours, and the humidity should be maintained at around 15%. Under these conditions, locusts are most active, like to eat, and are conducive to growth.

⑶ The food intake of locust larvae above the third instar gradually increases. At this time, it is necessary to ensure that there is sufficient food in the shed, otherwise it will affect their normal growth and may even cause cannibalism.

⑷ Keep the shed clean and clean it once every 1-2 days to prevent the occurrence of diseases.

4. Locusts are destructive insects

It is different from other special breeding industries. On the one hand, breeding it can turn harm into treasure and increase farmers' income, but on the other hand, it increases the number of locusts, forming a potential hazard. Necessary safety management measures must be taken for its breeding to achieve twice the result with half the effort. For large-scale breeding, based on 1 mu of breeding, a half-meter wide plant contamination isolation zone should be built around the breeding site, and the surrounding area should be fenced with wire mesh and equipped with pesticide sprayers. There are many kinds of pesticides to kill locusts. You can use 75% malathion emulsifiable concentrate or 2.5% diazinon and other pyrethroid insecticides to kill them.

If farmers do not want to breed locusts anymore, they must take the final extermination measures. If farmers do not want to breed locusts anymore, they should make preparations in advance. They cannot remove the breeding shed before May 20th of each spring. After all the locusts emerge from the ground and before they become adults, they should be killed with pesticides. This way, there will be no harm. If farmers decide not to breed locusts before the end of autumn, they must sell all the locusts before September 10th, that is, before they mate, or kill them with pesticides. They must not be allowed to lay eggs in the breeding shed. Such measures can ensure the eradication of potential harm in the future and benefit the healthy development of the locust breeding industry.

Biological characteristics and value of locusts: Locusts are both medicinal and edible insects, oviparous, belonging to the order Orthoptera, family Acrididae, class Insecta. According to statistics, there are 859 species of locusts in the family Acrididae, and there are two main types of locusts that can be used as medicine and food, namely the East Asian migratory locust and the Chinese rice locust. These two locusts are rich in nutrition, with soft, tender meat and delicious like shrimp. According to books such as "Research on Migratory Locusts" and "Feed Value of Migratory Locusts", locusts are rich in active substances such as protein, carbohydrates, insect hormones, and contain vitamins A, B, C and trace elements such as phosphorus, calcium, iron, zinc, and manganese. Locusts are not only delicious food, but also a good medicine for treating diseases, with the effects of warming the stomach and ribs, strengthening the spleen and digestion, and dispelling wind and relieving cough. "Compendium of Materia Medica" records that locusts can be used alone or in combination to treat a variety of diseases, such as tetanus, infantile convulsions, fever, asthma, sha swell, cormorant plague, frostbite, tracheitis, and prevention of cardiovascular and cerebrovascular diseases. You can boil ten of them into a decoction, or fry them and grind them into powder and drink, five per time. For frostbite, fry them and grind them into powder and mix with sesame oil and apply to the affected area.

With the development of society and the continuous improvement of the quality of life, the human table has changed from traditional types such as chicken, duck, fish and meat to green game. Locusts are rich in nutrition, tender in meat, and delicious like shrimp. In Hong Kong and other places, they are known as "flying shrimps" and are a favorite delicacy for people from all over the world. In the United States, "insect banquets" are held to entertain guests, among which locusts are included. According to reports, some patients with obesity, hypertension, cardiovascular and cerebrovascular diseases currently tend to eat insects in order to achieve the purpose of losing weight and curing diseases. Insect food has become popular in some countries and regions accordingly. Insects are used to cook dishes, or made into canned food, biscuits, ice cream and other foods, which are very popular.
