CATDOLL : CATDOLL: When did you start raising silkworm pupae?

1. How to raise silkworm pupae? Note, it is silkworm pupae?

1.

In the process of raising silkworms, the first thing to pay attention to is the breeding time. Silkworms prefer warm seasons for their growth habits. Therefore, it is most appropriate to breed silkworm pupae in spring and summer. In addition, the silkworm pupae should also be bred according to the growth of mulberry leaves to ensure that their feed can be supplied.

2.

In terms of temperature requirements, silkworm pupae aged 4 to 5 years old are suitable for indoor breeding environment above 20℃. Do not breed them in a high temperature and high humidity environment, as this is not conducive to the growth and development of silkworm pupae.

3.

When you find that the small dots on the silkworm eggs account for 20% of their body, you should cover them with black cloth to block out the light. On the morning of the third day, you should take off the black cloth, then wrap up the silkworm eggs and wait for them to hatch.

4.

In addition, young silkworm pupae require more nutrition, so more feed needs to be fed during this period. At the same time, the excretion of silkworm pupae is also large, so extra attention should be paid to ventilation and cleaning in the breeding room.

2. How to cultivate silkworm pupae?

Silkworms prefer warm seasons to grow, so spring and summer are the best seasons to breed silkworm pupae. In addition, silkworm pupae should be bred according to the growth of mulberry leaves to ensure that their feed is adequately supplied.

In terms of temperature requirements, silkworm pupae aged 4 to 5 years old are suitable for indoor breeding environments above 20℃. Do not breed them in high temperature and high humidity environments, as this is not conducive to the growth and development of silkworm pupae. When the small spots on the silkworm eggs account for 20% of the body, they should be covered with black cloth to block light. On the morning of the third day, the black cloth should be removed, and then the silkworm eggs should be wrapped up and wait for them to hatch. In addition, young silkworm pupae require more nutrition, so they need to increase feed during this period. At the same time, the excretion of silkworm pupae is also very large, so extra attention should be paid to ventilation and cleaning in the breeding room.

How to raise silkworm pupae

Prepare the silkworm room, silkworm tools and mulberry leaves, and thoroughly disinfect the silkworm tools and silkworm room. In spring and summer, pour the silkworm eggs on paper to collect the silkworms, and then feed them 2-3 meals of fresh and tender small leaves every day, and control the temperature at around 27 degrees. When they grow to the second age, lower the temperature appropriately, feed them 2-3 meals of mulberry leaves every day, and do a good job of water and disease management. When they grow to the fourth age, the silkworms begin to make cocoons, and after peeling them open, you will get silkworm pupae.

At the same time, the excretion of silkworm pupae is also very large, so extra attention should be paid to ventilation and cleaning in the breeding room.

After buying the silkworm seeds, you first need to disinfect the breeding environment. It is recommended to use concentrated chlorine. On the one hand, there will be no chlorine residue, and on the other hand, it will not cause any major harm to the silkworm pupae. After disinfection, the environment must be sealed and the silkworm seeds can only be put in after sufficient disinfection.

When the silkworm pupae grow to the adult stage, they can be directly placed on the silkworm tree for feeding. Of course, there is a period of adaptation during this period. When the adaptation is complete, the adult silkworms will eat mulberry leaves on the silkworm tree and grow naturally. In addition, if it is found that there are almost no mulberry leaves on the silkworm tree for the silkworms to eat, the silkworms on the silkworm tree need to be picked up one by one, put in a basin, and then transported to a place with abundant mulberry leaves.

5. How to breed cicada pupae?

1. Breeding site: Generally, it can be carried out in a forest or orchard of a certain size. As long as the soil is not wet, waterlogged, and there are no insects, ants, or mice.

2. Collect egg branches: Every year when the cicadas are chirping, pay attention to which woods or orchards have the most cicadas, and then go to these places to collect egg branches.

3. Female cicadas usually lay eggs in July and August. They will choose to lay eggs on 4-5 cm tender branches. The best time to collect egg branches is in late autumn and early winter. Cut off the dry egg branches (at least 20 cm away from the cicada eggs) and bring them back to the breeding site.

4. Insert the collected egg branches into a pot with soil or other containers, and then bury them according to the degeneration of the cicada eggs. Generally, cicada eggs stay in the branches for about 30-35 days.

5. Planting of egg branches: Dig a hole about 30-40 cm long and deep under the tree, several dozen centimeters away from the trunk, bury 1-2 egg branches, and cover with soil. Try to complete it by the end of October, otherwise the survival rate of cicada eggs will be reduced, which will affect the production of cicada pupae. Or observe the egg branches, and when the cicada eggs are about to hatch into cicada ants, remove the egg branches in time, and then dig a hole to bury them. This can stagger the time of burying and the time of catching cicada pupae. Cicada eggs will hatch into cicada ants, suck the juice of the roots under the tree, and then begin to spend the first 2-3 years of their lives, or a longer period of time, and gradually develop into cicada pupae.

6. Daily management: Trees need to be managed regularly, including fertilizing, weeding, watering, etc., to ensure that the trees can grow well and provide the necessary nutrients for cicada ants to feed and degenerate.

7. Cicada pupa capture: When you first hear cicadas chirping, you should put 10-15 cm high plastic sheets around the branches where the eggs are buried to prevent the cicada pupae from breaking out of the soil and escaping. At the same time, you should also put plastic sheets or transparent tape around the base of the tree to prevent the cicada pupae from escaping through the tree.

6. What are the planting techniques and time for cicada pupae?

Artificial breeding technology

Every year from mid-to-late July to the end of October is the season when cicadas lay eggs most vigorously, especially from mid-to-late July to the end of September. At this time, cut off the branches where cicadas lay eggs, tie them into small bundles (20 cm away from the egg-laying section at both ends), and insert them vertically into a container filled with soil to keep the branches moist. Then, according to the degeneration of the eggs, dig a 40 cm deep and 30 cm long pit 30 cm away from the root of each tree every day, bury 1 to 2 egg-laying branches, sprinkle water when the soil is dry, and then fill the soil to bury it. Try to bury it around the end of October. If the branches are buried too late, the resistance of the cicada eggs will be weak, the survival rate will be low, the output will naturally be low, and they will survive longer underground (at least one year longer than normal pupation).

Whole fields of tung, poplar and fruit trees have dense roots, which are sufficient to provide the nutrients that cicada ants need for feeding and degeneration. Burying egg-laying branches in such densely populated areas will not only make the cicada ants grow faster, but also make it easier to capture the cicada pupae when they emerge from the ground, saving labor. The yield can be more than 6 times higher than that of burying branches in scattered areas.

Every day, you should observe the changes of eggs on the branches where eggs are laid. If you find branches that are about to transform into cicada ants, you should collect them in time and bury them under the roots of various trees immediately. This way, you can stagger the time with the first burial, so that there will be a gap between the time when the cicada pupae emerge from the ground, so that you can catch them every night. The method of burying branches this time is the same as the first time, but the pit should be closer to the roots of the tree. After burying, you don’t need to take any measures. The cicada ants can absorb nutrients from the roots of the tree to maintain their lives. This method will make the cicada eggs emerge 1 to 2 years earlier than burying them in the soil before they transform into cicada ants, and it will help to increase the survival rate and output.

Artificial breeding requires burying branches in different places at the roots of various trees once a year. This can produce more high-quality cicada pupae. Since the egg-laying branches are cut off, it will not affect the growth of the trees, but can also promote the emergence of new growth points at the cut site, which can be said to kill two birds with one stone.

Precautions for silkworm pupa breeding

8. In which month do we start breeding silkworm pupae?

Sericulture is divided into spring silkworms, summer silkworms and autumn silkworms. The time when silk cocoons are sold is when there are the most silkworm pupae, usually from June to October.

The temperature in Guangdong is higher, so spring cocoons are produced earlier and autumn cocoons are produced later. But the pupae can only be sold after the cocoons are peeled. If you find a silk factory, they will have dried silkworm pupae in all seasons.
