What kind of business scope does the cultivation of golden cicadas belong to?

Cicada breeding, the business scope belongs to the breeding industry.

Golden cicada, also known as grasshopper cicada, belongs to the family Cicadidae in the order Homoptera of the class Insecta. It is an insect with incomplete metamorphosis, and its growth and development go through three stages: egg, nymph, and adult.

Primary seed sources can be obtained by naturally collecting in the field. Eggs, nymphs, and adults can all be collected as seed sources. All stages of insects can be collected from July to September; August to September is the best season for collecting nymphs, and September is the best time to collect cicada egg branches. Cicadas can be collected all year round.

To collect 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- to 2-year-old thin tangerine branches that have been killed by cicada eggs. Any tangerine branch with a flat stem on one side and an incomplete surface and a large number of milky white long oval eggs embedded in the wood under the skin is a cicada egg. Cut off the excess eggless tangerine branches above the egg-laying nest, leave 10 to 15 cm of eggless branches below the egg-laying nest, and bundle about 50 branches into a small bundle and put them in a plastic bag for later use.

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 in the seed source site are concentrated indoors to promote hatching. Hatching method: In a plastic box of 70cm x 40cm x 20cm, spread 5 to 10cm thick fine sand on the bottom, and place the egg branches in bundles vertically or horizontally on it. Use a small sprayer to spray mist water continuously to maintain high humidity around the branches with eggs, so that excess water droplets are absorbed in the fine sand at the bottom. At the same time, 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 (single-year eggs). Dig a regular narrow trench about 30 to 50 cm deep, such as a ring, square, triangle, parallel or radial shape, for later digging and harvesting. After breeding, cover the soil and compact it, and keep a record of the time, quantity, breeding trench shape and depth.

Providing growth conditions

Choose healthy tree species with well-developed lateral root systems, lush growth, and more juice, such as poplar, elm, willow, or various fruit trees in the orchard (preferably fruit trees). In addition, intercrop some root and tuber plants, such as potatoes, sweet potatoes, and yams. The depth of grasshoppers should be 30 to 50 cm. 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 high water content or water accumulation. To ensure the normal growth and development of the host plant root system, the young and tender plants should be well developed and juicy. In winter, wheat straw, rice straw, corn stalks, etc. should be covered in the breeding area to maintain the ground temperature.

Building production facilities

In addition to collecting locust eggs naturally, a gauze greenhouse can be built to provide space for adults to lay eggs. Fruit trees in abandoned orchards can be used to replant fruit tree seedlings, and cement or bamboo sticks can be used to build fences around them, with iron wires in the middle and nylon window screens on the outside. The adults that have emerged or been collected 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.

Harvest

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 rain. The nymphs (cicada turtles) dig holes in the soft and wet ground with a pair of saw-toothed front feet. After crawling out of the ground, they move for a short time on the ground. Then they climb along the 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 illuminate and catch them on the ground and trunks under the trees at night. Or you can catch the emerging young adult cicadas on the trees in the early morning.

What are the technical methods for breeding cicadas?

The video of the golden cicada breeding technology is as follows:

Select breeding 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 management; interplant fruit tree seedlings between trees to increase the branches for cicadas to lay eggs; plant cicada eggs under the trees. Refer to the "Cicada Breeding Technology" for methods.

Build breeding greenhouses: Build breeding greenhouses before the cicadas are about to emerge, with an area of ​​1 mu for 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.

Management and epidemic prevention of seed insects: After the cicadas emerge from the ground, they have strong phototropism. In the early stage, they should be allowed to enter the greenhouse after they have emerged from the molts. When catching them, the molted cicadas will fly around and bump into the light, causing the seed insects to die. 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 seed eggs. Each greenhouse can provide about 20 mu of cicadas for breeding.

Egg collection: Egg collection is done in autumn after the cicadas lay eggs, usually around the seventh month of the lunar calendar. The 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. 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 45 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 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 broad-leaved tree plot planted with poplars, willows and fruit trees.

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 a circle of transparent tape at one meter to prevent the cicada ants from climbing high and metamorphosing. Cicada ants will become adults 18-24 months from the date of sowing.

5. In particular, it includes planting and breeding land, egg collection, hatching, sowing, nutritional supplementation, harvesting, using mixed nutrients, on the one hand, providing nutrition for fruit trees, and on the other hand, supplementing nutrition for cicadas through tree sap. At the same time, different types of fruit trees are selected to provide different nutritional juices for cicadas, so as to obtain cicadas with rich nutritional value; the method of the present invention is used to cultivate cicadas, with high hatching rate and short breeding cycle. Using fruit trees as a habitat increases the application value and obtains double economic benefits.

Obtaining 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 throughout the year. 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 lightly 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 and the surface is incomplete, and there are a large number of milky white long oval eggs embedded in the subcutaneous wood. It is cicada eggs. Cut off the excess eggless dead branches above the egg-laying nest, leave 10-15 cm eggless branches below the egg-laying nest mark, and bundle about 50 into a small bundle and put it in a plastic bag for later use. To capture nymphs, naturally mature nymphs are the target. Nymphs can be collected by illuminating the base of the tree trunk with a flashlight from 7 to 12 in the evening; after collection, put them in a gauze cage to hatch and lay eggs. The host planted in the egg-laying cage is a shrub, mainly a variety of fruit trees. There are many ways to catch adult cicadas on trees, such as using a fire to lure them at night. In order to ensure that the adult cicadas are not damaged, wheat gluten can be used to catch them. The method is to rinse the dough with water several times to remove the starch, leaving pure gluten, store it in a large lotus leaf or poplar leaf, stick it to the top of a bamboo pole, and catch the adult cicadas in the early morning or during the day. [2]

The collection of egg-laying branches should be the main way to obtain seed sources.[1]

Breeding

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

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.

The harvest of artificially raised nymphs (cicada turtles) should be dug from the ground or allowed to emerge freely during the harvest season according to the market price. During the production season, the fresh nymphs are washed with clean water to remove the mud and sand. Each 100 grams of nymphs are placed in a box, and water is added to cover the nymphs (cicada turtles) in the box, and then frozen in the refrigerator for storage. After re-washing, they can be processed and used. There are long-term storage methods for nymphs (cicada turtles) such as freezing or pickling, and short-term storage such as flooding with water, soaking in dilute salt water, or natural storage after unearthed.

1. Breeding site: Breeding under forests, various fruit trees and timber trees can meet their growth needs.

2. Heating: In the seventh month of the lunar calendar, cicadas enter the heating period, and cicada eggs should be collected in time.

3. Post-egg processing: After collecting the branches with cicada eggs, remove the dry leaves, cut off the two ends, tie them into a bundle, spread a layer of sand on the bottom of a large washing basin, put the bundled branches upright in the basin, and keep the temperature between 28 and 34 degrees.

4. Bury after hatching: When 20% of the larvae have hatched, they should be buried. Choose an area with many soft hairy roots so that the larvae can absorb nutrients from the roots.

5. Sowing: Dig the pit into strips, the depth should be mainly to the hairy roots, put the branches with hatched larvae into the pits, and be gentle when returning the soil. Cicadas will become adults 15 to 18 months from the date of sowing, and can be harvested in time.
