CATDOLL : CATDOLL: Is the survival rate of golden cicada breeding high? (Is the survival rate of golden cicada breeding high? Zhihu)

1. What is the survival rate of cicada seedlings?

The output is related to a combination of factors. Cicadas appear in the evening of July in the Gregorian calendar. It is impossible for us to watch the breeders every day to calculate the output. The egg branches and hatched cicadas we provide are the best verification.

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%.

2. In which month can artificially bred cicadas survive?

When breeding cicadas, choosing a suitable time is also very critical. It cannot be too early or too late, otherwise it will affect the survival rate of cicada breeding. Normally, the eggs are often hatched from March to May each year, and the best breeding time is May. If the eggs are purchased before March, they are likely to be frozen, thus affecting the hatching rate. If they are bred in June, they will often slowly die at this time, and they may die before hatching is completed. Even if they are successfully hatched, their physique is very weak, and the survival rate will not be too high.

The time for breeding cicadas is scientifically based. If the breeding is too dry, the soil temperature is low, and the survival rate is low, the yield will be affected. If the breeding is too late, the larvae will not easily overwinter. In June and July, when the temperature is high, people will have serious allergic reactions in the incubator. Choosing the right incubation time, the quality of the incubation of cicada eggs is the key to the success of cicada breeding. Therefore, when hatching cicada eggs, the first thing is to sterilize and kill insects with drugs, and then strictly control the temperature and humidity. Remember that the temperature is high and low, and the humidity is too high or too low. According to the thermometer and humidity meter, but also frequently check the cicada branches and control them flexibly. In the incubator for about 10 days, pay attention to the muscimol or green bacteria on the cicada branches and soak them in a 1:100 times bactericidal compound for about 5 seconds. Pay special attention after 30 days of incubation. If you find that 3%-5% of the young cicadas are crawling at the bottom of the pot, you should bury them under the tree.

How long does it take to artificially breed cicadas?

Cicadas become adults 15 to 18 months from the date of sowing.

Golden cicada breeding technology Golden cicada is an oviparous and underground incubated medicinal material with extremely high medicinal value. It has the effects of clearing blood and removing blood stasis, health care, and has a certain therapeutic effect on hypertension. However, the existing golden cicada has the disadvantages of long growth cycle, low survival rate, and is not suitable for collection.

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.

3. What is the general survival rate of cicadas?

The output is related to a combination of factors. Cicadas appear in the evening of July in the Gregorian calendar. It is impossible for us to watch the breeders every day to calculate the output. The egg branches and hatched cicadas we provide are the best verification.

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. Is it better to raise cicadas with live cicada seedlings or hanging them on branches?

It is better to plant seedlings because the survival rate is high.

The larvae of cicadas live in the soil and have a pair of strong digging forelegs. They use piercing-sucking mouthparts to suck the juice from the roots of plants, weakening the tree, causing the branches to die and affecting the growth of trees. They usually stay in the soil for several years or even more than ten years, such as 3 years, 5 years, and 17 years. These numbers have one thing in common, they are all prime numbers. This is because prime numbers have very few factors, and when they drill out of the soil, they can prevent themselves from drilling out with other cicadas and competing for territory and food. When they are about to emerge, they drill out of the soil surface at dusk and at night, climb up the tree, and then hold on to the bark and molt. When a black crack appears on the back of the cicada pupa, the molting process begins. The head comes out first, followed by the green body and wrinkled wings. It stays for a while to harden the wings and darken the color, and then it begins to take off. The whole process takes about an hour. At the end of June, the larvae begin to emerge into adults. The newly emerged cicadas are green, and the longest lifespan is about 60 to 70 days. In late July, the female adults begin to lay eggs, and the peak period is in early and mid-August. Most of the eggs are laid on branches with a thickness of 4 to 5 mm. In summer, they make loud calls on trees and suck sap with their needle-piercing mouthparts. The larvae live in the soil and suck sap from the roots, which is harmful to trees.

5. 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%.
