CATDOLL : CATDOLL: How many years is the best time to unearth golden cicadas after breeding? (How many years is the best time to unearth golden cicadas after breeding?)

1. What are the differences in the growth cycles of artificially cultivated cicadas?

Generally, the larvae go to the ground after hatching and emerge in two years! Pesticides cannot be sprayed on forest land, and ants need to be removed regularly! The price of cicadas is the highest in the early and late stages, so whoever's cicadas are unearthed in advance can sell them at a good price. The price is the lowest during the peak period of unearthing! Adapting to the seasons to unearth is a common breeding method!

If you want to raise cicadas faster, the best thing is to plant fruit trees in a greenhouse. Not only can they produce fruits, but the high temperature in the greenhouse can also allow the cicadas to be unearthed early. The price of cicadas that are put on the market early is quite high!

2. What is the harvest time for cicada monkey breeding in Henan?

Cicadas are usually harvested after about three years of breeding. Some of them can come out in two years, some in four years, and most in the third year. The specific differences are caused by the different thickness of the tree roots that the cicada ants parasitize after entering the soil and the different temperatures of the forest. Grasshopper cicadas are also called cicadas, and their cicada shells and male cicadas can be used as medicine. The newly unearthed old larvae are rich in nutrition, with a protein content of 58-58% and a fat content of 10-32%. Cicadas are now on the table as health foods, and the market demand is increasing, and the price is getting higher and higher.

3. What is the growth cycle and temperature of the cicada?

Cicadas become adults 15-18 months after sowing. Under good growth conditions, a small number of cicadas will emerge from the ground in about 2 years, but most will emerge in about 3 years.

It usually takes 3 to 5 years for the cicada to complete one generation. The cicada overwinters in the form of eggs on young branches of the current or biennial year and nymphs of various ages on plant roots in the soil. There are two types of overwintering insects: eggs and nymphs of different sizes. The overwintering sites are also divided into two environments: aboveground and underground. The overwintering eggs begin to hatch in mid-May of the following year, with the peak hatching period from late May to early June, and the hatching activity ends in late June. The egg period is nearly 300 days.

The activities of overwintering nymphs are affected by ground temperature and the sap of the host plant. When the temperature is above 10℃~15℃, the sap of the tree begins to flow, and the overwintering nymphs begin to pierce and suck food. The nymphs hatched from the overwintering eggs (called cicada ants) dive into the soil and suck sap from the roots of the host plant. As the age increases, they create soil chambers of different sizes and shapes and live in them. Part of the wall of the soil chamber is attached to the roots of the plant for feeding. After the temperature drops in autumn, they drill into the deep soil layer to overwinter, and migrate upward to the roots of the tree after the spring warms up. The number of nymphs in the soil is the highest in May of the year. This is when a large number of overwintering eggs are hatched and buried in the soil, and it is also the period when the last instar nymphs are about to emerge from the soil and molt into adults. After completing the entire life cycle of the nymph in the soil, the mature nymphs drill out of the soil from late May to mid-to-late August, and crawl to the branches of shrubs, stems of weeds, etc., fix themselves on the bark and branches with their claws and thorns on their front feet, and shed their skin to become adults.

4. How many seasons does the Cicada Monkey Shed have in a year?

once.

Advantages: easy to collect and manage.

Disadvantages: The growth cycle is long, and you need to purchase and install a greenhouse. There will be no harvest in the first two years, but there will be harvest after that. The breeding cost is relatively high, which is the main reason why there is less breeding now.

In nature, cicadas basically emerge every 3-5 years, but artificially bred cicadas have a shorter growth cycle. If the growth conditions are good, a small number of them will emerge every two years, but most of them will emerge in three years. It usually takes 2-3 years to breed golden cicadas in a greenhouse. At the beginning, the cycle will be long and investment costs will be required, but later you can harvest every year.

5. When will the cicada seedlings come out?

It usually takes about 2-3 years for cicadas to emerge from the ground. If you want to shorten the breeding cycle, you can increase the density of trees appropriately or carry out constant temperature breeding.

When the cicada completes the entire development process of the larval stage, the mature larvae will generally drill out of the ground from late May to mid-to-late August, and crawl to the branches of shrubs, stems of weeds, etc., and then use their claws and thorns on their front feet to fix themselves on the bark, branches and leaves, and finally shed their skin and emerge as adults.

The peak period for the appearance of adults is generally from mid-June to mid-July. After the adults emerge from their pupae, they will mate and lay eggs about 20 days later. Egg-laying usually begins in late June, with the peak period from late June to late August. The end of egg-laying is from mid-September to early October, or the egg-laying ends in early October.
