CATDOLL : CATDOLL: How long is the breeding cycle of golden cicadas? (How long is the breeding cycle of golden cicadas?)

1. How many seasons are there in a year for the Cicada Monkey Shed?

once.

Advantages: easy to collect and manage.

Disadvantages: The growth cycle is long, and you need to purchase and install a greenhouse. There will be no harvest in the first two years, but there will be harvest after that. The breeding cost is relatively high, which is the main reason why there is less breeding now.

In nature, cicadas basically emerge every 3-5 years, but artificially bred cicadas have a shorter growth cycle. If the growth conditions are good, a small number of them will emerge every two years, but most of them will emerge in three years. It usually takes 2-3 years to breed golden cicadas in a greenhouse. At the beginning, the cycle will be long and investment costs will be required, but later you can harvest every year.

2. How often do we release young cicadas in cicada farming?

2-3 years, because its larvae need to spend the first two or three years of its life underground, or perhaps longer. Then when the time comes, it will crawl out of the soil, climb up the tree and begin to emerge into an adult, and die 60-70 days after becoming an adult.

3. How many batches of cicadas are raised in a year?

It takes three years from cicada egg laying to harvesting cicada pupae. The eggs are collected in autumn, usually around the seventh month of the lunar calendar, and the larvae will hatch in about fifteen days. At this time, you can see some larvae crawling up and down on the branches. When about 20% of the larvae have hatched, they should be buried.

How are cicadas bred?

1. Egg collection: Egg collection is done after the cicada lays eggs in autumn, usually around the seventh month of the lunar calendar. The cicada uses the small thorns on its tail to pierce the tender branches of one year old trees and lay eggs in the branches, mostly on juicy branches such as fruit trees. After laying eggs, the branches will dry up, so most branches with green lower ends and dry tips have cicada eggs.

2. Post-harvest processing: After collecting the branches with cicada eggs, remove the dry leaves, cut off the two ends, and bundle thirty branches into a bundle. Spread a layer of sand on the bottom of a large washing basin, and put the bundled branches upright in the basin. Keep the temperature at 28-34 degrees and the humidity moist. Spray it when it is dry. Use a sprayer to spray the branches until they are thoroughly wet.

3. Hatching: The larvae will hatch in about 15 days. At this time, you will see some larvae crawling up and down on the branches. When about 20% of the larvae have hatched, they should be buried. The burial pit should be in an area with many fine and soft hair roots so that the larvae can absorb nutrients from the roots. It is best to choose a plot where honeysuckle is planted.

4. Sowing: Dig a pit into a strip shape, the depth should be mainly to the hairy roots, and the width should be one shovel. Put the branches with hatched larvae into the pit, and the larvae will hug the plant roots by themselves. Be gentle and slow when returning the soil. Do not step on the soil after returning it, and do not water it to ensure ventilation.

5. Harvesting: If there are trees, wrap them with transparent tape at a distance of one meter to prevent the cicadas from climbing high to metamorphose. Cicadas will become adults 15-18 months after sowing.

6. Tips: Cicada eggs are collected mainly from wax branches and fruit tree branches. Cicada egg larvae feed on the juice of plant roots, so it is best to choose a multi-root area when burying. Each branch contains 100-400 cicada eggs, so 500-800 branches per mu are appropriate to ensure the survival rate. Using this method to grow golden cicadas can advance the original growth period of 3-15 years to 18 months, the incubation period from the original one year to about 35 days, and the survival rate from the original 6% to about 30%-60%. Therefore, it is particularly suitable for breeding in rural areas.

Nowadays, the price of golden cicadas has been rising, and golden cicadas have been served on the tables of restaurants of all sizes. The prospects are promising. The survival rate of golden cicadas planted in this way is high. If the minimum survival rate is 30% per acre, about 100,000 cicadas can survive.

What should we pay attention to when breeding cicadas?

Golden cicadas are different from other animals. They have a certain breeding time limit. If they are raised too early or too late, the survival rate of golden cicadas will be greatly affected. Basically, it should be started around March every year, but it also depends on the weather conditions. If the temperature in March is too low, it can be postponed to May. But be careful, it must not be done in relatively cold weather, which will easily lead to freezing and greatly reduce the probability of golden cicada hatching.

After entering June, the growth of cicadas has entered the middle stage, so it is too late to start hatching at this stage. Many cicadas have not yet decomposed, but casualties have already begun. You should know that cicadas are very fragile, unlike other animals, so the temperature and time in breeding are very important. If either of them is not kept up, it is easy to directly lead to breeding failure.

We all know that wild cicadas generally live in trees. Various woods are their homes, and they are often the most numerous in summer. Therefore, when breeding, we should also pay attention to providing a better environment as much as possible, and also pay attention to the environment in the soil. The moisture in the soil should not be too high, but also not too little, and try not to have stagnant water. Secondly, try not to choose a nursery when breeding, but choose some orchards, so that the cicadas can continue to grow. If there are some natural cicadas around the breeding cicadas, then we should also consider the adaptability of the environment and try to choose carefully.

Since all the eggs in the golden cicada breeding are buried in the soil at the beginning, the soil is a key link in the entire breeding process. Of course, the choice of soil at the beginning is also very important. Try to choose some organic soil, which should be relatively soft and you can also add some sand, which is very good for the growth of golden cicadas.

If there is no such soil, you can also choose some loess, but you must pay attention to the water. Too much water will directly cause the cicada to suffer from hypoxia at the beginning of its growth, which is extremely detrimental to their survival and can easily lead to breeding failure.

What is the market prospect of cicada breeding?

Cicadas can be bred under various fruit trees, timber trees, and forests, and there is no need for feeding management or epidemic prevention during the entire breeding process. Therefore, cicadas will not be contaminated by feed additives, pesticides, or hormones. They are pure natural, pollution-free, high-protein, low-fat green wild insects, and are very popular among consumers. In recent years, hotels, restaurants, and refrigerated food factories have come to purchase them, and the market prospects for their cultivation are very broad.

4. How many times do you need to plant seedlings to raise cicadas?

3-4 times bacteria.

The growth cycle of cicadas is 3-5 years, and the artificial breeding cycle is generally about 280-300 days. To shorten the breeding cycle, the density of trees can be appropriately increased, or constant temperature breeding can be carried out. When breeding cicadas, it is necessary to choose sunny and loose soil plots as breeding sites. The water content of the soil should not be too high or there should be water accumulation. The tree species are suitable to choose willow, elm, poplar and other varieties. The breeding time of cicadas is preferably from May to June. Before placing the egg branches, the soil preparation for the cicada ants should be well prepared.

5. How often do cicadas reproduce?

1. What is the breeding season for cicadas? The egg branches of cicadas are hatched from the end of February to the end of June in the Gregorian calendar, and the hatched egg branches are planted from the beginning of April to the middle of July. It is not good to be too early or too late. Reasons: (1). According to our many years of breeding practice and repeated experiments, the egg period of cicadas is generally about 280 to 300 days. In July, the cicada eggs have begun to die in large numbers, and their vitality has decreased. Some of them die before hatching (there are very few poplar branches left), and they are very likely to die during the hatching process. The survival rate is less than 10% of the normal situation. (2). The cicada egg branches produced in the same year will not hatch small cicadas because they have a dormant period. Therefore, only the egg branches of the previous year can hatch. Don't be fooled by the unscientific promises of some farms that cicadas can be hatched and bred at any time. (3). Some farms say that as long as they hatch and do not see the small cicadas, they can still breed. This is pure nonsense. The result of such breeding can only be said that the survival rate is extremely low, less than 1%, and the cycle is as long as 3-5 years. 2. Survival rate? Yield? Yield is related to comprehensive factors. Golden cicadas come out in the evening of July in the solar calendar. We cannot watch the breeders every day to calculate the yield. The egg branches and hatched golden cicadas we provide are the best verification. We are developing for the long term. We are not like other seed supply places. They say that the survival rate is 80%, which is impossible to achieve that high. They say that the yield per mu is guaranteed, which is all exaggeration. After years of practice and experiments, we have summarized a new planting method, which increases the survival rate by 10-20% compared with the ordinary planting method (the survival rate of ordinary planting methods is only about 20%, and ours can reach 30-50%. Some farms boast about 70% and 80%, which is absolutely impossible. This is nearly ten times more than the natural one. That is to say, one branch produces about 60-100 golden cicadas, about 100 per kilogram, and the yield is determined by the number of branches (500 branches per mu will produce about 300 kilograms per mu). Don't be fooled by some farms' so-called 70% and 80% survival rates.>

Artificial breeding technology of cicadas/golden cicadas To successfully raise cicadas, you should master the key points of seed source acquisition, host plant selection, breeding site selection, and protective measures configuration:

1. Obtain the seed source. Primary seed sources can be collected naturally in the field. Eggs, nymphs, and adults can all be collected as seed sources. All insect stages can be collected from July to September; August to September is the best season for collecting nymphs; September is the best time to collect cicada egg branches, and they can be collected all year round. For collecting eggs, you can choose an ideal place with dense trees and many cicadas. Use fruit branch shears or a long pole with a hook on the top to gently remove the 1-2 year old thin dry branches on the tree that have been killed by cicada eggs. Any one side is flat and dry with an incomplete surface, and the subcutaneous wood is inlaid with a large number of milky white oblong eggs. It is cicada eggs. Cut off the excess eggless dead branches above the egg-laying nest, and leave 10-15 cm eggless branches below the egg-laying nest. Bundle about 50 branches into a small bundle and put them in a plastic bag for use. To capture nymphs, naturally mature nymphs are targeted. Nymphs can be collected by shining a flashlight at the base of the tree trunk between 7 and 12 pm; after collection, they are placed in a gauze cage to hatch and lay eggs. Shrub-like hosts are planted in the egg-laying gauze cage, mainly various fruit trees. There are many ways to catch adult cicadas on trees, such as using fire to lure them at night. In order to ensure that adult cicadas are not damaged, wheat gluten can be used to catch them. The method is to rinse the kneaded dough with water several times to remove the starch, leaving pure gluten, store it in a wide lotus leaf or poplar leaf, stick it to the top of a bamboo pole, and catch the adults in the early morning or during the day. The collection of egg-laying branches should be the main way to obtain seed sources.

2. Breeding. The breeding targets are newly hatched nymphs and eggs that are close to hatching. Collect the branches with eggs directly from the wild or from the seed source site and gather them indoors to promote hatching. Hatching method: In a plastic box 70 cm long, 40 cm wide and 20 cm high, spread 5 to 10 cm thick fine dry sand on the bottom, place the egg branches in bundles vertically or horizontally on it, and constantly spray mist with a small sprayer to maintain high humidity around the branches with eggs, so that excess water droplets are absorbed in the fine sand at the bottom. In the meantime, the hatching of eggs should be checked continuously. When nymph activity is found, the branches and fine sand can be placed in the breeding site.

The breeding time is generally from September to October (two-year eggs) or from June to July (first-year eggs). 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 ring, square, triangle, 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 and the growth period is

The weight is only about 1 gram, and the whole body and eyes are milky white; in the second year, the weight grows to about 3 grams, the whole body pigment deepens, and the eyes are pink; in the third year, the nymph (cicada turtle) develops to maturity.

The weight is 4.5 to 5 grams, with an average of 210 per kilogram. At this time, the body color is brown and the eyes are dark gray. According to the weight, body color depth and eye color changes, the nymph can be accurately judged.

The age period of growth and development.

3. Supply high-quality feed. Choose healthy tree species with well-developed root systems, lush growth, and more juice, such as poplar, elm, willow, tung or various fruit trees in the orchard. In addition, intercropping

Some root vegetables, such as potatoes, sweet potatoes, yams, etc.

4. Provide good environmental conditions. The appropriate depth for the "breeding" of cicadas is 30 to 50 centimeters. They should be exposed to the sun and protected from freezing. The soil should be soft, fertile, and pollution-free. They should not be too dry or contain water.

The amount of water is too high or there is water accumulation to ensure the normal growth and development of the host plant root system, and the young plants are 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.

5. Build facilities for the production of adults and nymphs. In addition to naturally collecting cicada eggs, you can build a gauze greenhouse to provide space for adults to lay eggs. You can use the fruit trees in abandoned orchards and replant them.

For fruit tree seedlings, use cement pillars or bamboo sticks to build a fence around them, and then stretch iron wire in the middle, and cover the outside with nylon window screen.

The number of adults can be retained as needed, without having to collect seed sources from the wild.

6. Do a good job of epidemic prevention. The nymphs (cicada turtles) that have just emerged from the ground and the adults that have just emerged from the shells have many natural enemies, such as toads, snakes, rats, hedgehogs, wild cats, sparrows, and mantises, all of which like to eat nymphs.

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 also cause harm to nymphs (Cicada turtles) or cicadas.

It is relatively large and should be carefully cared for and protected during breeding.

The most important seasons are the egg-laying stage, the outbreak of cicada ants, and the emergence of mature nymphs. The natural enemies of the egg-laying stage and the outbreak of cicada ants are mainly ants and red flower bugs. The treatment measures are:

Use 100 times diluted ammonia to wash the egg-bearing branches, or use DDVP, strong chlorine, etc. to treat the soil.

1. Select breeding trees. Dwarf fruit trees such as apricot trees, peach trees, apple trees or other waxy dwarf shrubs are good trees for cicada breeding. Pay attention to timely pruning of high branches to facilitate breeding management, interplant fruit tree seedlings in the gaps between trees to increase the branches for cicadas to lay eggs, and plant cicada eggs under the trees. Refer to "New Technology for Cicada Breeding" for methods.

2. Build a breeding greenhouse. Build a breeding greenhouse on the eve of the golden cicada being unearthed. Each greenhouse should be 1 mu in area. Use cement columns or bamboo sticks to build a fence around the breeding area. The row spacing of cement columns is 5 meters. Use bamboo poles to build a frame in the middle, and then pull iron wire to fix it. Then cover it with nylon window screen. For breeding, choose a plot with high and dry terrain and convenient drainage and irrigation. Avoid building a breeding greenhouse in a low-lying plot that is easy to store water.

3. Seed management and epidemic prevention. After the cicada emerges from the ground, it has a strong tendency to phototropism. In the early stage, it is necessary to wait until it has emerged as an adult before entering the greenhouse. When catching, the emerging cicada will fly around and bump into the light, causing the seed insect to die. Therefore, all the cicadas unearthed within the first week can be caught, and the cicadas can be allowed to naturally emerge and lay eggs after a week. The seed density is about 10,000 per mu, with males and females accounting for about 50% each. Each female cicada can lay 500-1500 eggs. Each greenhouse can provide about 20 mu of cicada breeding seeds. The cicada can mate and lay eggs about 20 days after the emergence of the cicada. When laying eggs, the cicada pierces the epidermis of the branches and lays eggs in the wood. Try not to walk around or make noise in the greenhouse during the mating and egg-laying period of the cicada to avoid adverse effects on the cicada.

Since there are many natural enemies of nymphs (cicada turtles) after they emerge from the soil and adults after they emerge from the molt, such as toads, sparrows and mantises, protection work should be done in the greenhouse. In addition, the screens should be checked frequently to see if they are damaged to prevent the golden cicada from escaping. Microorganisms such as Beauveria bassiana, Metarhizium anisopliae and Entomogenetic algae (cicadae) can cause parasitic damage to the golden cicada seed insects, so protection should be strengthened during breeding. During the period when mature nymphs emerge from the soil, the egg stage under the tree and the period when cicada ants occur, the main natural enemies of the golden cicada are ants and red flower bugs, which must be strictly prevented. Strong ammonia can be used for soil treatment.

4. Collect and preserve the eggs. Early to late September is the best season for collecting cicada eggs in the breeding greenhouse. You can use fruit branch shears or a long pole with a hook on the top to cut off the 1-2 year old thin, dry and incomplete surface of the tree, and the subcutaneous wood with a large number of milky white long oval eggs, which are cicada eggs. Cut off the excess eggless dead branches above the egg-laying nest, leave 5-10 cm eggless branches below the egg-laying nest, and bundle 50-100 branches into a small bundle, put them in a plastic bag or flatten them in the hatching room, and then use them for seed after natural treatment.

Do a good job in epidemic prevention.

1. There are many natural enemies of nymphs (cicada turtles) after they emerge from the soil and adults after they emerge from the pupae, such as toads, snakes, rodents, 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 parasitic damage. In addition, floods and pollution from pesticides and fertilizers are also harmful to nymphs (cicada turtles) or cicadas, so they should be carefully protected during breeding.

2. 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 strong ammonia solution to wash the egg-bearing branches or DDVP, strong chlorine, etc. to treat the soil.

Construct adult and nymph production facilities.

In addition to collecting cicada eggs naturally, you can build a gauze greenhouse to provide space for adults to lay eggs. You can use the fruit trees in abandoned orchards to replant fruit tree seedlings, and use cement columns or bamboo sticks to build fences around them, and then pull iron wires in the middle, and cover the outside with nylon window screens. The adults that have emerged or been collected can mate and lay eggs in it, and you can keep the number of adults as needed later, without having to collect seed sources from the wild.

Provide good 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.

The breeding targets are newly hatched nymphs and eggs that are close to hatching.

1. Collect egg-bearing branches directly from the wild or from the seed source site and gather them 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.

2. The breeding time is generally from September to October (two-year eggs) or from June to July (first-year eggs).

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.

3. 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 to grow in June, and the weight is only about 1 gram, and the whole body and eyes are milky white;

In the second year, the weight grows to about 3 grams, the pigmentation of the whole body deepens, and the eyes turn pink;

In the third year, the nymphs (cicada turtles) mature, weighing 4.5 to 5 grams, with an average of 210 per kilogram. At this time, the body color is brown and the eyes are dark gray. Based on the weight, body color and eye color changes, the time and age of the nymph's growth and development can be accurately determined.

6. What is the growth cycle and temperature of the cicada?

The growth period of the cicada is three months, and the temperature is 50 degrees.

The main factors for the incubation of cicada eggs are air humidity and temperature. Although we can control the incubation temperature of cicada eggs through the greenhouse effect, we must plant them within a specific period of time. Because the young cicadas (cicada ants) that have just hatched from the cicada eggs are extremely weak and can easily die.

7. How often do artificial cicadas reproduce?

Artificial cicadas reproduce once every 5 years

Cicadas live on the ground for a short time, only about ten days and a half months. This is also the precious time for them to find a mating partner, mate and lay eggs, and maintain the reproduction of the population. Then they will die one after another. Therefore, golden cicadas can only lay eggs once in their lifetime.

8. What is the breeding cycle of cicada pupae?

The breeding cycle of cicada pupae is three years.

The growth cycle of farmed cicadas is 2-3 years, because the larvae need to spend the first two or three years of their lives underground, or perhaps longer. Then when the time comes, they will crawl out of the soil, climb up the tree and begin to molt into adults, and they will die 60-70 days after becoming adults.

.The lifespan of cicadas: Different species of cicadas have different life cycles. The life cycle of French cicadas is mostly 4 years, while there are cicadas in North America with a lifespan of up to 17 years. The lifespan of Chinese cicadas is mostly between 3 and 7 years, nearly half of which are 5 years, and a few can live for 8 to 9 years.
