How to breed golden cicada

1, breed. Feeding objects are newly hatched nymphs and nearly hatched eggs. Branches with eggs collected directly from the wild or in the provenance are concentrated indoors to promote hatching. Hatching method: In a plastic box with a length of 70cm, a width of 40cm and a height of 20cm, the bottom is paved with fine dry sand with a thickness of 5- 10cm, the egg branches are tied vertically or horizontally, and the water is continuously sprayed with a small sprayer to keep the air around the egg branches high in humidity, so that excess water drops are absorbed by the fine sand at the bottom. Check the hatching of eggs constantly in the middle. When nymphs are found to be active, we can put branches and fine sand in the breeding place.

2. Under the tree of the host plant in the breeding ground, the ground is about 1 m away from the base of the trunk, and regular narrow ditches with a depth of about 30 ~ 50 cm are dug for later excavation and collection. After "planting seeds", compact the soil and record the time, quantity, groove shape and depth of "planting seeds".

3. Grasshoppers need to grow underground for three winters and summers (actually two years) from the egg stage to the mature nymph (cicada turtle): in June of the first year, the growth weight is only about 1 g, and the whole body and eyes are milky white; In the second year, the body weight developed to about 3 grams, the whole body pigment deepened and the eyes were pink; In the third year, the nymph (cicada turtle) is mature, weighing 4.5-5g, with an average of 2 10 per kilogram. At this time, the body color is brown and the eyes are dark gray. According to the changes of body weight, body color and eye contact, the time and age of nymph growth and development can be accurately judged.

4, harvesting and processing. The middle and late June (from summer to around) to early August (around the beginning of autumn) is the best season for field harvest, and the weather is most concentrated in early July or after rain. If an insect (cicada turtle) digs a hole with a pair of serrated front feet in the wet and soft ground, it will make a short movement on the ground after climbing out of the ground, and then climb the trunk or scaffold to prepare to shed its shell. At 4 ~ 6 o'clock the next morning, it will appear in the form of cicada, so it can be caught on the ground and the trunk under the tree at night or on the tree in the early morning with a flashlight.

5. The harvest of artificially raised nymphs (cicadas and turtles) should be excavated from the ground in time at the market price during the harvest season or let them be freely unearthed and captured. In the production season, the collected fresh nymphs are washed away with clear water, each box is 100g, and the nymphs (cicada turtles) in the box are submerged with water and stored in the refrigerator. It can be processed and utilized after re-cleaning. The preservation methods of nymphs (cicada turtles) include long-term preservation such as freezing or pickling, short-term preservation such as soaking in water, soaking in light salt water or natural preservation after excavation.
