CATDOLL : CATDOLL: What should I use to disinfect a room that has never been used to raise silkworms?

1. What to use to disinfect a room that has never been used to raise silkworms?

There are several common ways to disinfect a room:

①Open all doors and windows to let in as much sunlight as possible. Sunlight is the best disinfectant.

② You can heat the pot and pour vinegar into it while it is hot. The vinegar will evaporate immediately! This method is very good for disinfection!

③Spray a certain concentration of disinfectant and irradiate with ultraviolet light (this is probably not easy to achieve).

④ First spray with the insecticide commonly sold in daily chemical stores, then spray with 84 disinfectant, close the doors and windows for 3-5 hours, and then clean it thoroughly and you're done. I hope it helps!

2. How to disinfect freshly-made silkworm feces so that its medicinal efficacy is not reduced?

Low temperature sterilization, so that the effective protein components will not be denatured

3. What are the main contents of silkworm breeding and silkworm disease prevention and control?

Silkworm diseases used to be mainly caused by midgut pus disease and hollow-head softening disease. Currently, due to the differences in silkworm rearing time and climatic conditions, blood-type pus disease, stiffness disease and other silkworm diseases are the main ones.

1. Blood-type pus disease (commonly known as crawling silkworms, grandmother silkworms)

The virus of blood-type pus disease parasitizes in the blood of sick silkworms. The blood of healthy silkworms is colorless and transparent, while the blood of sick silkworms is milky white, so sick silkworms are also called milky silkworms. Once the silkworms become ill, as the disease worsens, the sick silkworms will crawl frantically with milky white pus, so they are also called crawling silkworms. The sick silkworms spread a large amount of viruses on mulberry leaves and silkworm pus by crawling, causing healthy silkworms to eat the virus-carrying mulberry leaves and become infected and sick.

1. The main cause of the disease. Due to the presence of viruses in incomplete disinfection, the tenderness of mulberry leaves with high water content, the high temperature and humidity in the silkworm rearing environment, and the lack of early-stage steaming and waking treatment, healthy silkworms and diseased silkworms are mixed and infected each other.

2. Prevention and control methods. Before each feeding, extract the diseased silkworms with milky white bodies and frantic crawling, put them into a container with lime and bury them deeply, then wash your hands and disinfect the silkworm bodies and silkworm seats with fresh lime powder 1-2 times a day. In feeding, pay attention to the maturity of mulberry leaves, do not eat tender leaves and immature leaves (the leaves used for the first instar are the 2nd-3rd leaves of the new shoots, the leaves used for the second instar are the largest leaves of the new shoots, the leaves used for the third instar are the three-eye leaves, and the leaves used for the fourth instar are the full bud leaves), and pay attention to indoor ventilation. There should be air convection windows in the room for sleeping silkworms of 1-2 instars, the indoor air should be circulated for 3-4 instars, and the doors and windows should be opened for the 5 instars. If it is rainy and the mulberry leaves are wet, it is more important to open the doors and windows for raising silkworms.

2. Rigidity

The conidia (white hairs) of the dead silk disease are brought in by the wind, mulberry leaves and other external factors. After landing on the silkworm body, they drill into the silkworm body after 10-12 hours, absorb the silkworm body's nutrition and water to sustain life. After one day, they drill out of the silkworm body again to produce hyphae and conidia, which are then transmitted to healthy silkworms through the conidia.

1. Cause of disease. The presence of conidia of the spores of the spores and high humidity in the air are conducive to the growth of conidia of the spores of the spores. The disease is usually more likely to occur in the rainy spring, summer and late autumn.

2. Prevention and control methods. Eliminate sick silkworms in time, catch them before their bodies turn white to prevent infection, and burn or bury the caught sick silkworms. Eliminate late-sleeping and sleepless silkworms in time during breeding, and disinfect the bodies and silkworm seats of susceptible silkworms such as ant silkworms, starter silkworms, and mature silkworms.

Prevention and control when the disease is mild: In addition to routine disinfection of silkworm bodies and silkworm seats during the larval stage, the silkworm bodies and silkworm seats should be disinfected once a day during the fifth instar. Sprinkle more charred rice bran and lime during sleep to keep the silkworm seats dry.

Prevention and control when the disease is serious: In addition to routine disinfection of silkworm bodies and silkworm seats for ant silkworms, starter silkworms and mature silkworms, the silkworm bodies and silkworm seats should be disinfected twice a day during the fifth instar stage, and the pressure material during dormancy should be changed from lime to anti-rigidity powder.

The specific drugs for the prevention and control of the disease include: "Miejiangling" anti-rigidity powder, "Youlujing" anti-rigidity powder, and the antibacterial agent "402". "Xiongxiaojing" can also be used for fumigation disinfection. During the silkworm period, 200 times liquid "Xiaoteling" can also be used for spraying disinfection.

4. What should we feed silkworms to make them produce various kinds of silk?

It is reported that the color of silkworms changes because the feed contains nutrients and specific pigments extracted from plants, chemical ingredients, and artificially synthesized mulberry leaves. The silk cocoons of colored silkworms are all colorful, and the silk produced does not need to be dyed. The breeding is mainly based on professional feed.

Feeding has the following characteristics:

1. All raw materials of silkworm artificial feed are pure natural and pollution-free. They are sterilized at high temperature and high pressure before leaving the factory, and the feed has a long storage period.

2. The artificial feed provided can feed the silkworm larvae in sufficient quantity until they can spin cocoons, and they can grow and develop normally, spin silk, spin cocoons and emerge normally.

3. As long as the temperature is suitable (20°C~30°C), silkworms can be raised all year round regardless of seasonal changes.

4. Strict disinfection and disease prevention measures are implemented for artificial feed silkworm farming. After the silkworms are sold (usually at the age of 3), they rarely die under normal feeding conditions, and the success rate of breeding is very high.

5. The formula of artificial silkworm feed and the technology of colored silkworm and cocoon have high technical content and are unlikely to be counterfeited.

Feeding method:

1. Raising silkworms in plastic boxes prevents feed from drying out and becoming contaminated. There are ventilation holes on the lid of the feeding box, so the lid must be kept closed during feeding. In addition, when the silkworms reach the fifth age, they must be divided into two boxes for feeding (one box for every three silkworms). In case of continuous rainy weather, the lid can be opened for 1-2 hours every day to allow the silkworms to ventilate and dehumidify.

2. During feeding, do not move the silkworms when they are sleeping; do not grab the silkworms that have just shed their skin, as their skin is very tender, to avoid hurting them. In addition, do not change the feed to mulberry leaves when feeding the silkworms, as they will not like to eat the feed anymore.

3. When the original feed in the plastic box is eaten up or dried, pick up the silkworms with clean chopsticks, pour out the remaining feed crumbs and silkworm feces in the box, take out the ham-shaped silkworm feed in the paper box, cut a small hole at one end of the feed with scissors, squeeze the feed into the feeding box through the small hole, and then put the silkworms on the feed. Each ham-shaped feed can be squeezed 2-3 times. To prevent contamination, the opened feed should be placed in a clean plastic bag. Silkworm feed has a specific taste and does not contain anything harmful to human health, so you can raise it without worry.

4. Pay attention to hygiene during the breeding period. Do not let water droplets on the feed to prevent mold on the feed. Do not let the silkworms come into contact with various household insecticides, mosquito repellents, perfumes, camphor, cigarettes and other things with strong odors to avoid causing harm to the silkworms.

5. In order to increase the fun, we use the technology of colored silkworms and colored cocoons to turn the original white silkworms into colored silkworms. If these silkworms are fed with ordinary feed, they will produce white cocoons. If they are fed with special colored cocoon feed, they can produce light red, yellow, light blue and other colored cocoons. The special colored cocoon feed is fed to the silkworms on the 2nd and 3rd day of the 5th year of age, and is fed for 3 to 4 consecutive days. It should be noted that different colored feeds should be raised separately. The silkworms fed with red cocoons have purple-red bodies, the silkworms fed with blue cocoon feed have a little blue body, and the silkworms fed with yellow feed have a slightly yellow body.

6. When you see the silkworms starting to spin silk, open the paper cocoon attached to one side of the silkworm box and secure it inside the box. You can then place the mature silkworms that are about to spin silk on the paper cocoon to make cocoons. To prevent the mature silkworms from crawling out, you can cover the cocoon with a piece of paper.

7. The silkworms will pupate about 6 to 8 days after spinning cocoons. If you need to observe the pupation, you can cut one end of the cocoon with a knife 2 to 3 days after cocooning, pour out the silkworms that have not yet pupated, and gently place them on clean soft paper. You can see the process of transformation from pupa to moth by observing frequently.

8. Silkworm cocoons can be dyed or painted with various colors and patterns to make cute animals or flowers. This is very popular in Japan. It depends on your rich imagination. Try it yourself.
