1. How to cultivate cicada monkeys artificially?

Methods and conditions for artificial breeding of cicadas: 1. Soil. Generally, cicadas prefer fruit trees, which are rich in sap, so they are generally chosen in land with fertile soil, but you must choose flat land, and there should not be too much water.

2. 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.

3. What is the whole process of artificially breeding cicadas?

1. The egg collection time of cicadas is after they lay eggs in autumn, usually around the seventh month of the lunar calendar. Cicadas use the small thorns on their tails to pierce the tender branches of one-year-old trees and lay their eggs inside 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. Processing after egg collection: Collect the branches with cicada eggs, remove the dry leaves, cut off the two ends, 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 method: larvae will hatch in about fifteen days. At this time, you will see some larvae crawling up and down on the branches. When about 20% of the larvae are hatched, they should be buried. The burial pit should be selected 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. In a plastic pot that is 10 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 in the air around the golden cicada egg branches so that excess water droplets are absorbed in the fine sand at the bottom. During the hatching period, the hatching of the golden cicada eggs should be checked continuously. When a small number of golden cicada larvae are found to be active, the branches can be placed in the breeding site together with the fine sand for planting.

4. For sowing, dig the pit into strips, with the depth mainly reaching the hairy roots and the width being one shovel. Place the branches with hatched larvae into the pits, and the larvae will hug the plant roots by themselves. Return the soil gently and slowly. After returning the soil, do not step on it, let alone water it, to ensure ventilation.

5. Sowing time. The 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 and tender plants should be developed and juicy. In winter, wheat straw, rice straw, corn straw, etc. should be covered in the planting area to maintain the ground temperature.

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

7. Collection. Cicada eggs are mainly made of white wax strips, and 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 acre 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.

4. Let’s talk about how to artificially cultivate cicadas?

The tree species generally selected include poplar, sycamore, elm and willow, etc. In order to better meet the food needs of the golden cicada's growth, the selected tree species must be healthy tree species with well-developed root systems, lush growth and more sap. Temperature is particularly important for hatching golden cicada eggs. The incubation temperature is generally controlled at 25~35℃, and the maximum cannot exceed 38℃. If the temperature is too low, it will prolong the time for the insects to emerge. March to July each year is the time for hatching eggs. During the incubation process, it is necessary to ensure the temperature and maintain humidity. To maintain humidity, you can use a sprayer to spray water on the golden cicada's eggs every day to keep them moist.

It usually takes 35 days for the eggs to hatch. When the emergence rate reaches 20%, the cicada strips can be planted at the roots of trees. When planting, dig a trench about one meter away from the roots of the tree, with a depth of 30~50CM and a width of 20CM. Then, plant the cicada larvae and eggs in the trench, fill it with soil, and face the sun to prevent frost. The soil should be loose, fertile and pollution-free. The soil should not be too dry or too wet. In winter, you need to cover the planting area with straw, corn stalks, etc. to maintain the temperature.
