Selective breeding of trees

Dwarf fruit trees such as apricot trees, peach trees, apple trees or other dwarf shrubs are good trees for cicada breeding. Pay attention to timely pruning of high branches to facilitate breeding and management; interplant fruit tree seedlings between trees to increase the branches for cicada egg laying; plant cicada eggs under the trees, refer to the "Cicada Breeding Technology" for methods.

Building a breeding greenhouse

Before the cicadas are about to emerge, build breeding greenhouses, with an area of ​​1 mu each. Use cement columns or bamboo sticks to build fences around the breeding area, with a row spacing of 5 meters. Use bamboo poles to build a frame in the middle, and then pull iron wire to fix it, and then cover it with nylon window screens. For breeding, choose high and dry land with convenient drainage and irrigation. Avoid building breeding greenhouses in low-lying land that is prone to water accumulation.

Pest management and epidemic prevention

After the cicadas emerge from the ground, they have a strong tendency to move toward light. In the early stage, they should be allowed to enter the greenhouse after they have emerged from the molts. When catching them, they will fly around and bump into the light, causing the death of the seed insects. Therefore, all the cicadas that have emerged from the ground within the first week can be caught, and they can be allowed to naturally emerge and lay eggs after one week. The seed density is about 10,000 per mu, with males and females accounting for about 50% each. Each female cicada can lay 500 to 1,500 eggs. Each greenhouse can provide seeds for the reproduction of cicadas on about 20 mu of land.

About 20 days after the cicadas emerge from their pupae, they can mate and lay eggs. When laying eggs, the cicadas pierce the epidermis of the branches and lay their eggs in the wood. During the mating and egg-laying period, try not to walk around or make noise in the greenhouse to avoid adverse effects on the cicadas.

Since there are many natural enemies of nymphs (cicada turtles) after they emerge from the soil and adults after they emerge from the shells, such as toads, sparrows and mantises, protection work should be done in the greenhouse. In addition, the gauze nets should be checked frequently to prevent the cicadas from escaping.

Microorganisms such as Beauveria bassiana, Metarhizium anisopliae and Entomogenetic algae (cicadae) can cause parasitic damage to cicadas, so protection should be strengthened during breeding. During the period when mature nymphs emerge from the soil, eggs under trees and cicada ants occur, the main natural enemies of cicadas are ants and red flower bugs, so they must be strictly prevented. Strong ammonia can be used for soil treatment.

Feed supply

Choose healthy tree species with well-developed root systems, lush growth, and more sap, such as poplar, elm, willow, tung, or various fruit trees in the orchard. In addition, intercrop some root and tuber plants, such as potatoes, sweet potatoes, and yams.

Environmental conditions

The appropriate depth for the "breeding" of cicadas is 30 to 50 centimeters. They should be sunny and frost-proof. The soil should be soft, fertile, and pollution-free. It should not be too dry, nor should it have too much water or water accumulation. This ensures that the root system of the host plant grows and develops normally, and that the young plants are tender, developed, and juicy. In winter, the breeding area should be covered with wheat straw, rice straw, corn straw, etc. to maintain the ground temperature.

Epidemic prevention preparation

There are many natural enemies of nymphs (cicada turtles) after they emerge from the soil and adults after they emerge from their shells, such as toads, snakes, mice, hedgehogs, wild cats, sparrows and mantises, which all like to eat nymphs (cicada turtles). Microorganisms such as Beauveria bassiana, Metarhizium anisopliae and Entomogenetic algae fungi (Cicada fungus) also cause harm. In addition, floods and pollution from pesticides and fertilizers are also harmful to nymphs (cicada turtles) or cicadas.

Breeding technology

In addition to collecting cicada eggs naturally, we can build gauze greenhouses to provide space for cicada adults to lay eggs. We can use the fruit trees in abandoned orchards to replant fruit tree seedlings, build fences around them with cement columns or bamboo sticks, and then stretch iron wires in the middle, and cover them with nylon window screens. The emerged or collected adults can mate and lay eggs in them, and the number of adults can be retained as needed, without having to collect seed sources from the wild.

The planting time of cicada

Planting time is generally from May to July or from September to October. Dig regular narrow trenches about 10 to 30 cm deep about 1 meter away from the base of the trunk, such as ring, square, triangle, parallel or radial shapes, for the purpose of later digging and harvesting. Cover the soil and compact it after "planting", and keep records of the time, quantity, "planting" trench shape and depth. It should be sunny and frost-proof, with soft, fertile and pollution-free soil; it should not be too dry, nor should it have too high water content or water accumulation, to ensure the normal growth and development of the host plant root system, and the young plants should be tender, developed and juicy. In winter, wheat straw, rice straw, corn straw, etc. should be covered in the planting area to maintain the ground temperature.

Harvesting Golden Cicadas

After burying the egg branches for 2-3 years, the cicadas begin to grow and mature gradually. The harvesting period is generally during the summer solstice every year. If there is a heavy rain, the fat and strong nymphs will start to drill out of the ground at 4-5 am, or after the rain, the nymphs will dig a hole in the soft ground with a pair of saw-like front feet. After crawling out of the ground, they will do a short exercise on the ground, and then climb the tree trunk or trellis to prepare to shed their shells. After 2-4 hours, they will shed their skin and become cicadas (cicadas). According to this characteristic of the golden cicada, after the summer solstice every year, if there is no rain and drought, the breeding site can be artificially irrigated to induce the cicadas to emerge. Before the cicadas emerge, or before the cicadas mature, a circle of smooth plastic film can be tied around the tree trunk 30 cm above the ground to prevent the cicadas from continuing to crawl up the tree for easy harvesting. You can also use a flashlight to illuminate and catch them on the ground and tree trunks under the tree at night. Or catch the young adult cicadas on the tree in the early morning.

Precautions

The most important seasons are the egg stage on trees, the occurrence of cicada ants, and the emergence of mature nymphs. The natural enemies of the egg stage on trees and the occurrence of cicada ants are mainly ants and red flower bugs. The treatment measures are to use 100 times the solution of strong ammonia to wash the egg-bearing branches or DDVP, strong chlorine, etc. to treat the soil.

2. How to raise cicada monkeys? How many can be raised in one acre of land?

One acre of orchard can plant about 200 cicada egg-bearing branches, each of which can produce 60-100 cicadas, so 5 acres of land can raise 60,000 to 100,000 cicadas.

3. What is the survival rate of cicada monkey breeding?

The survival rate of breeding is about 50%. This depends on your management skills. According to the current breeding level, it is 50%.

At present, the survival rate of artificially bred cicadas is 30%-50%, which is nearly ten times more than that of natural ones. That is to say, one branch can produce about 60-100 cicadas, and about 100 cicadas per kilogram. The yield is calculated based on the number of branches. Don't be fooled by the unscientific promises of some farmers that the survival rate is 70% or 80%.

4. How to breed cicadas?

1. Breeding

The breeding targets are newly hatched nymphs and eggs that are close to hatching. The branches with eggs collected directly from the wild or from the seed source are concentrated indoors to promote hatching.

Hatching method: In a plastic box 70 cm long, 40 cm wide and 20 cm high, spread 5-10 cm thick fine dry sand on the bottom, place the egg branches in bundles vertically or horizontally on it, and spray mist with a small sprayer to keep the air around the egg branches high in humidity so that excess water droplets are absorbed by the fine sand at the bottom. The hatching of eggs should be checked continuously in the middle. When nymph activity is found, the branches and fine sand can be placed in the breeding place.

Dig regular narrow trenches about 30 to 50 centimeters deep, about 1 meter away from the base of the trunk, under the host plant tree in the breeding place, such as circular, square, triangular, parallel or radial shapes, for the purpose of later digging and harvesting. After "breeding", cover the soil and compact it, and keep records of the time, quantity, "breeding" trench shape and depth.

From the egg stage to the mature nymph (cicada turtle), the cicada needs to grow underground for three winters and summers (actually 2 years): the first year starts in June, the weight of the growth is only about 1 gram, the body and eyes are milky white; the weight grows to about 3 grams in the second year, the body pigment deepens, and the eyes are pink; the nymph (cicada turtle) matures in the third year, weighing 4.5-5 grams, with an average of 210 per kilogram, the body color is brown, and the eyes are dark gray. According to the weight, body color depth and eye color changes, the time and age of the nymph's growth and development can be accurately determined.

2. Harvesting and Processing

The best season for field harvesting is from mid-to-late June (around the summer solstice) to early August (around the beginning of autumn). The most concentrated season is in early July or after the rain. The nymphs (cicada turtles) dig holes in the soft ground with a pair of saw-toothed front feet. After crawling out of the ground, they move on the ground for a short period of time, then climb on tree trunks or trellises to prepare for molting. They emerge as adult cicadas at 4 to 6 in the morning of the next day. You can use a flashlight to catch them on the ground and trunks under trees at night, or catch the young adult cicadas on trees in the early morning.

5. How many cicadas can be planted per acre of land?

Cicada breeding is a new breeding industry. There are 2,000 cicada seedlings per mu, and each cicada seedling contains 100 cicada eggs. Artificial hatching can reach more than 80%! To be precise, the current yield per mu is 100-300 kilograms.

Golden cicada has extremely high nutritional value and unique taste, especially the newly unearthed nymphs, which contain the highest protein, making it a rare high-protein, low-fat game delicacy. In addition to its edible value, grasshopper cicada also has extremely high medicinal value, making it a top-grade medicinal food.

6. How to plant cicada seedlings?

1. Site. To plant golden cicada, you need to choose tree species with well-developed lateral roots, lush growth, and abundant sap, preferably in an orchard.

2. Soil: First, place the cicada larvae in loose, fertile soil, sandy loam can be chosen.

3. Nutrition: After the cicada breaks out of the soil, you can apply decomposed organic fertilizer to promote growth.

4. Watering: During the growth period of the cicada, it needs a lot of water, and the soil should be kept moist at all times.

7. How many cicada seedlings are needed per acre of land?

Use about 25 grams of cicada seedlings per acre of land.

The breeding of cicadas requires planting trees on the land. If you own the land, you can save about one-third of the cost.

Golden cicadas need to suck the roots of trees to grow, so they need trees. You can plant dozens of poplars or fruit trees per acre. Each seedling costs 1-2 yuan, and fruit trees cost about 10 yuan. The amount of seedlings per acre should be determined based on the conditions of the seedlings and the forest land. The yield of golden cicadas is also based on the seedlings and forest land.
