The method of artificial incubation and semi-culture of golden cicada

You should be familiar with cicadas. In summer, you can often hear the cries of cicadas in trees, especially in the muggy noon when you want to take a nap at home when you hear the annoying sound of cicadas outside the window. in fact, cicadas are not only annoying, on the one hand, they are also very rich in nutritional value.

The method of artificial incubation and semi-culture of golden cicada

1. Egg collection. Egg collection is after the golden cicada lays eggs in autumn, usually around July of the lunar calendar. The golden cicada spines into the annual twigs with small thorns in its tail, laying eggs into the branches, mostly fruit trees and other succulent branches, and most of the branches will dry up after laying eggs, so most of the green branches at the bottom and dry ends have cicada eggs.

2. Postharvest treatment. After collecting the branches with cicada eggs, remove the dry leaves, cut off the two ends, tie thirty into a bundle, spread a layer of sand at the bottom of the large laundry basin, put the bound branches into the basin, keep the temperature at 28Mul 34 degrees, humidity is kept moist, that is, spray when dry, spray the branches thoroughly with a sprayer.

3. Hatching. The larvae hatch in about fifteen days. At this time, you will see some larvae climbing up and down the branches. About 20% of the hatched larvae are buried, choosing areas with fine soft roots so that the larvae can absorb nutrients from the roots, preferably in plots where honeysuckle is planted.

4. Sow seeds. Spread the hatched golden cicada larvae around the tree trunk.

5. Harvest. If there are trees, wrap one more circle with transparent tape at one meter to protect the cicadas from climbing and metamorphosis. The cicada will become an adult within 18 months from the date when the cicada is sown.

The cicada eggs are mainly collected by white wax strips, and the cicada egg larvae feed on the sap of plant roots, so it is best to choose multi-root zones when burying. There are 400 cicada eggs in each branch, so it is appropriate to have 2000 cicada eggs per mu to ensure the survival rate. Using this method to grow golden cicadas, the original growth period of 3mur15 years was advanced to 18 months, the incubation period was increased from one year and months to about 35 days, and the survival rate was increased from 6% to 30%. 60%. Therefore, it is especially suitable for farming in rural areas.

Acquisition of provenance of golden cicada

1. Egg collection. Egg collection is after the golden cicada lays eggs in autumn, usually around the seventh month of the lunar calendar. The golden cicada spines into the annual twigs with small thorns in its tail, laying eggs into the branches, mostly fruit trees and other succulent branches, and most of the branches will dry up after laying eggs, so most of the green branches at the bottom and dry ends have cicada eggs. The collection of eggs can choose an ideal place with dense cicadas, using fruit branch shears or long poles with hooks at the top to cut off the withered branches of golden cicadas on the tree, tie them into a small bundle of 50-100 pieces, and put them into a plastic bag for use.

In addition to the natural collection of cicada eggs, a screen greenhouse can be established to provide space for adults to lay eggs. You can use the fruit trees in the abandoned orchard to replant the fruit tree seedlings, set up a fence around with cement columns or bamboo sticks, and set up iron wire in the middle, which can be covered with nylon window screen. When the captured adults are put into them to mate and lay eggs, the number of adults can be retained as needed, and there is no need to collect provenances from the wild.

2. Postharvest treatment. After collecting the branches with cicada eggs, remove the dry leaves, cut off both ends, tie 30 into a bundle, spread a layer of sand at the bottom of the large laundry basin, put the bound branches into the basin, keep the temperature at 28% 34%, keep the humidity at 28%, that is, spray when dry, spray the branches with a sprayer until they are wet.

The living habits of the golden cicada

Cicadas belong to Insecta, Homoptera, Cicadellidae. After the eggs are transformed into cicada ants, they live underground for at least 4 years, or even more than ten years before they can be unearthed into cicada pupae. When unearthed, use jagged forelimbs to dig out the ground from soil less than 30 centimeters deep, climb up tree trunks or other climbers, and by means of air drying and self-ability, the crack line from the top of the head to the center of the back is transformed into a cicada. And then suck the sap of the tree and survive for more than 70 days, that is, aging and death. Adult cicadas and larvae are selective in sucking sap, mainly poplar, paulownia, elm and fruit trees.

Cicadas live on trees for only about 3 months, so they need to mate and lay eggs as soon as possible. One male cicada will mate with 5-8 female cicadas to complete their mission. Each female cicada can lay 800 to 1000 eggs. They often choose young branches with a diameter of 4 cm to 5 cm. They first pierce the bark with the ovipositor, insert the ovipositor into the xylem of the twig, creating claw pores, and then lay their eggs in them, arranged in single or double rows or "Y" shape, and then fly to another branch to lay eggs until the eggs have been laid.

The eggs were nourished in the branches for 30 to 35 days, at this time, the spawning branches dried up, and the eggs were also feathered into cicada ants, fell under the tree into the soil, sucked the sap of the roots, and began to live underground. It was not until 4 years later that they could break out of the ground and live on the ground, so that cicada pupae were unearthed every year. According to nutrition experts, (www.nczfj.com) cicada pupae contain protein, a variety of essential amino acids, fat, potassium, calcium, phosphorus, zinc and other nutrients, which can improve human immunity after eating.

Artificial culture technology of golden cicada

It is the most vigorous season for cicadas to lay eggs from mid-late July to the end of October every year, especially from mid-late July to the end of September, when the branches of cicadas are cut, bundled into small bundles and planted in utensils filled with soil to maintain the moisture of the branches. Then, according to the molting of the eggs, dig a pit 40 cm deep and 30 cm long under each tree 30 cm from the root of the tree every day, bury 1 or 2 spawning branches, wet the soil with water when it is dry, and then fill it flat, and strive to finish burying it around the end of October. If the branches are buried too late, the resistance of cicada eggs is weak, the survival rate is low, the yield is naturally low, and the survival time in the ground is longer.

Because the roots of the whole land of paulownia, poplar and fruit trees are dense enough to provide nutrition for the absorption and molting of cicada ants, burying spawning branches in this dense place can not only grow fast, but also be easy to capture and save labor when cicada pupae are unearthed, and its yield can be more than 6 times higher than that of scattered buried branches.

Every day, we should frequently observe the changes of eggs on the spawning branches. if we find that the branches that are about to degenerate into cicada ants, they should be collected in time and buried under the roots of each tree immediately, so that they can be staggered with the time buried for the first time, so that the time when the cicada pupa is unearthed is spaced so that it can be caught every night. The method of burying branches this time is the same as the first time, except that the hole should be closer to the root of the tree, and without taking any measures after burying, cicada ants can absorb nutrients from the roots and maintain their own life. This method is one or two years earlier than the cicada eggs buried in the soil before they are transformed into cicada ants, and helps to improve the survival rate and yield.

Artificial breeding requires burying branches in different parts of the roots of all kinds of trees once a year, so that more high-quality cicada pupae can be produced. Because the spawning branches are cut off, the growth of the trees will not be affected, and it can also promote the new growing points in the cut parts. It can be said to kill two birds with one stone.

In many places in the north like to eat cicadas, because the nutritional value of cicadas is very rich, and it is said to be very delicious, but as an editor still dare not try. As people pay more and more attention to what they eat and prefer to eat something fresh, the delicacy of cicadas has been gradually discovered by more and more people.
