CATDOLL : CATDOLL: How to keep silkworms from getting sick (How to keep silkworms from getting sick)

1. What should we pay attention to when raising silkworms?

Details to pay attention to when raising silkworms

1. Remove sand before dormancy. This is to avoid excessive accumulation of silkworm feces, which can easily breed and spread pathogens and invade the silkworms during their dormancy.

2. Silkworms do not eat or move during the dormant period. They mainly rely on the nutrients absorbed by eating mulberry before dormancy to maintain their life activities. Therefore, they must sleep when they are full. If you stop feeding mulberry too early, they will starve to sleep. Starved silkworms are weak in constitution, poor in resistance, and prone to illness.

3. Silkworms are less resistant to external interference during their dormancy, so you must pay attention to their protection during dormancy. When 95% of the silkworms have fallen asleep, sprinkle them with fresh lime powder and silkworm medicine "Disease Prevention No. 1" to prevent pathogens from invading. If a small number of silkworms do not eat mulberry and do not sleep, it is because they have not found a place to sleep. At this time, add some mulberry leaves to help them sleep in batches.

4. Silkworms are temperature-changing animals, and their adaptability range is 20-30℃. In the spring silkworm period, the climate is often low and humid, so the focus is on replenishing warmth and removing moisture. In the summer silkworm period, the climate is hot and humid, so the focus is on cooling and removing moisture, keeping the air in the silkworm room flowing, and removing the stuffiness. In the autumn silkworm period, if the weather is hot and dry, it is necessary to replenish moisture indoors and combine disinfection, that is, spray the ground and walls with fresh lime powder and bleaching powder; you can also hang a wet cloth on the silkworm rack to keep the silkworm room moist to prevent the silkworms from having difficulty molting or half molting.

2. During the silkworm rearing process, how to ensure that the silkworms do not develop pus disease?

Introduction: It is common for sericulture to cause sericulture. In many areas, due to the lack of mature technology, lack of management of mulberry gardens, inadequate disinfection of silkworm houses, and the influence of climate, sericulture is caused, which restricts the development of sericulture. This disease will cause harm to silkworms of all ages, especially to old silkworms in the middle and late stages. In summer, the weather is hot and humid and there is no ventilation. Once sericulture breaks out, it is difficult to control.

Causes of pus disease in silkworm breeding

1. Disinfection measures are not in place and prevention awareness is weak

The virus of pustular disease can survive for a long time and can survive for 2 to 3 years without artificial control. Before raising silkworms, if the silkworm room and tools are not thoroughly disinfected, pathogenic microorganisms will still exist in the silkworm room. During the silkworm raising period, farmers have a weak awareness of disease prevention. In order to reduce investment expenditures, they do not disinfect thoroughly. They only disinfect the silkworm room of young silkworms, but not the adult silkworms. In addition, the tools in the silkworm room and the surrounding environment are not disinfected. Disinfection in this way can easily lead to the recurrence of pustular disease.

2. Lack of management of silkworm breeding, insufficient silkworm rooms and silkworm tools

Too rough feeding can weaken the silkworms' constitution. When their immunity drops, they are susceptible to purulent disease when the temperature rises or when it rains. Some farmers do not plan enough silkworm rooms and raise silkworms too densely. The silkworms are easily scratched, causing bacterial infection and purulent disease. Silkworms of all stages are mixed together, making it difficult to regulate the temperature and humidity of the breeding environment, and it is also difficult to distinguish between mulberry leaves for feeding, which can easily lead to secondary infection.

3. Improper management of mulberry leaves leads to poor leaf quality

When planting mulberry trees, some farmers, for the sake of convenience, do not adopt winter felling and improper fertilization. As a result, the mulberry leaves cannot be supplemented with nutrients, and pests and diseases will become serious, and the quality of mulberry leaves cannot be guaranteed. Some mulberry trees are fattened by animal feces and corpses, which will cause cross-infection of silkworms with pus diseases. The mulberry leaves picked by farmers are not stored in a special mulberry storage room, causing the mulberry leaves to dry up prematurely and have little nutritional value.

Increase disease prevention awareness and implement strict disinfection

☞Disinfection before silkworm rearing

Before raising silkworms, disinfection of the silkworm room and its surroundings is an indispensable task. First, disinfect the silkworm room and silkworm tools with 1% effective chlorine bleaching powder. This is the first step. After completion, wait a few days and move the silkworm tools outside for a second disinfection. The tools used at ordinary times should be soaked in bleaching powder for half an hour, and then put back into the silkworm room after drying. Then disinfect the entire silkworm room for the third time with bleaching powder. After three disinfections, the doors and windows of the silkworm room should be closed tightly, and some lime should be sprinkled on the ground for disinfection. The indoor temperature should be kept above 25 degrees.

☞Disinfection during feeding

Pus disease is easy to recur during the breeding process, and disinfection should be carried out regularly during the breeding period. The tools, silkworm seats, silkworm room floors, and mulberry storage rooms that silkworms often touch should be cleaned and disinfected with bleaching powder. In particular, the floor of the silkworm room must be desanded and disinfected before feeding silkworms. For example, 5-year-old silkworms are prone to pus disease. When disinfecting, use 3% effective chlorine anti-stiffness powder to evenly sprinkle it on the silkworm seats and silkworm bodies in a spraying manner. The relevant silkworm nets, sandbags, and anti-drying paper should also be disinfected together.

☞Disinfection in the later stage of silkworm rearing

After the silkworm breeding is finished, the silkworm room and silkworm tools must be disinfected to completely eliminate pathogenic microorganisms and block the transmission route. When the next batch is raised, the risk of pus disease can be avoided. The disinfection methods are similar and you can refer to the disinfection method before silkworm breeding.

Improve the breeding environment, increase nutrition, and enhance the resistance of silkworms

Silkworms of each age have different requirements for the breeding environment, so it is best to raise them in batches. When they reach the third age, the weak silkworms that develop slowly can be separated from the mature silkworms and raised separately, and the temperature and humidity of the silkworm room should be adjusted. Generally, young silkworms should pay attention to heat preservation and moisture retention, and adult silkworms should take measures to ventilate. Only when the breeding environment is good can the growth of pus disease bacteria be avoided.

Sericulture is suitable for sparse breeding, not dense breeding. If the breeding density is too high, the silkworms will have limited space to move around, which will easily lead to trauma and increase the incidence of purulent diseases. In the early planning, we should consider both the yield and the breeding density. If the space is crowded, we should expand the breeding space in time to leave some space between the silkworms to prevent them from scratching each other. During the period of young silkworms, we should select and remove the old and dry mulberry leaves, and feed them with high-quality mulberry leaves in appropriate amounts according to the feeding characteristics of silkworms.

When it is found that some silkworms are sick, the cause of the disease should be analyzed to prevent the disease from spreading further. Sick silkworms should be disinfected and centrally handled, and should not be discarded in the corners of the silkworm room at will to prevent the further spread of viruses and bacteria. Check carefully and exclude sick silkworms, then disinfect the silkworm racks and silkworm seats with fresh lime powder before feeding, and control the feeding amount. Silkworm feces should be cleaned in time and stored away from the silkworm room. They can be returned to the field after they are fully fermented.

Strengthen mulberry garden management, control the source, and select silkworms resistant to pus disease

Mulberry leaves are the main food source for silkworms. Only by controlling the source and growing high-quality mulberry leaves can there be sufficient nutrition to meet the growth needs of silkworms. When planting mulberry trees, apply fertilizers reasonably, remove weeds in the mulberry garden in time, and take measures to prevent insects to reduce the chance of cross-infection with insects and pests.

Different silkworm species have different antiviral abilities, and silkworms of different ages have different resistance abilities. Because septicemia is a common disease, silkworm species resistant to septicemia are currently on the market. Farmers can choose suitable septicemia-resistant silkworm species according to the local breeding climate characteristics, which can reduce the chance of silkworms suffering from septicemia during breeding.

summary:

Pus disease has caused great economic losses to silkworm farmers, and the main reason is that the disinfection work is not done well. For diseases like pus disease, prevention in the early stage is better than treatment in the later stage. Whether it is before or in the middle of silkworm breeding, disinfection should be thorough, including the silkworm room, tools or surrounding environment. As long as improvements are made from the mulberry leaves, regular disinfection, providing silkworms with comprehensive nutrition and increasing resistance, the incidence of pus disease will be greatly reduced.

3. How to prevent silkworm diseases when raising silkworms?

I am hesitant and don't understand this aspect of the problem! And I see no professional answer!

So I searched for information on the Internet!

Hope this helps!

In the breeding industry, silkworms are relatively rare invertebrate reptiles and belong to the insect family. Silkworms feed on mulberry leaves and go through four completely different developmental and growth stages in their life: eggs, larvae, pupae, and adults. For breeders, silkworms are insects with high economic value. By planting mulberry trees and raising silkworms, breeders can obtain cocoons and silk, and then obtain a considerable income. However, the process of breeding silkworms is often not so easy. Silkworms are small in size, short in lifespan, and do not have the perfect immune system of higher organisms. They are easily infected with bacteria, and because they are too small, it is difficult for managers to detect the symptoms of illness. Most silkworms die of illness. Therefore, breeders need to thoroughly clean and sterilize the living environment of silkworms to block the transmission medium and pathways of bacteria, pathogens and harmful microorganisms, which is a strong guarantee for improving breeding efficiency.

Importance of Disinfection in Silkworm Farming

According to the research and follow-up investigation, more than 90% of the diseases that endanger the death of silkworms are infectious diseases caused by viruses, bacteria, fungi and microparticle silkworm pathogens. Pathogenic microorganisms are the main source of harm, and they threaten the life safety of silkworms. In order to prevent silkworms from being infected with pathogens and causing unnecessary economic losses, farmers must insist on regular disinfection and sterilization of the breeding area to completely eliminate the harm of pathogens from the root. Silkworm rooms, silkworm tools, silkworm bodies, mulberry leaves, and clothing of breeding personnel all need to be disinfected and sterilized, and no source of pathogen invasion should be missed. Create a clean, pollution-free, healthy and green growth environment for silkworms.

How to prevent viral infection and death during silkworm breeding?

As the saying goes: prevention is better than cure. Silkworm diseases are generally caused by parasitism of viruses and bacteria. These pathogens will attach to the silkworm body, silkworm seat, silkworm tools, and mulberry leaves. Therefore, disinfection of silkworm farms is of utmost importance. The key links to prevent silkworm virus infection include meticulous feeding management and strict comprehensive health and epidemic prevention measures. Doing a good job of disinfection and sterilization of the environment, feed, drinking water, and utensils is an effective way to eliminate pathogenic microorganisms spread from the source of infection in the external environment, cut off the transmission route, and prevent the spread of infectious diseases.

Implementing the principle of "prevention first, taking precautions before they happen" is an important method of breeding. However, due to the special nature of sericulture, the disinfectant should be non-toxic, non-irritating, quickly dissolving and quickly releasing bactericidal active ingredients. It has a strong killing effect on various types of pathogenic microorganisms, does not react with inorganic and organic matter in water or produce toxic compounds, and is simple and convenient to operate.

Preventive disinfection and sterilization methods for silkworm farms:

The disinfection and sterilization work of the silkworm farm can be "sweep, wash, scrape, disinfect, and kill". First, the silkworm room and the tools should be thoroughly cleaned to leave no place for pathogens to hide. There should be no dust on the ground and a layer of ground should be scraped. Then, the silkworm tools should be thoroughly washed in running water and soaked in alkaline water. No stains should be left on the tools and each one should be cleaned. Then, the mud on the surface of the silkworm room should be scraped off. If conditions permit, the silkworm room can be repainted. Finally, the silkworm room and tools should be disinfected with chemicals. The chemicals must be prepared according to the standards. In order to give full play to the efficacy, the chemicals should be sufficient and evenly applied. No dead corners should be left when spraying.

1. Cleaning: Since there is more than half a year between the last autumn silkworms and the next spring silkworms, the silkworm room, cocooning room, auxiliary room, and the environment are covered with dust and dirt, and there are potential sources of silkworm diseases, which pose a potential threat to the spring silkworms. In the preparation work before raising silkworms, the cleaning utensils should be used to clean thoroughly, leaving no dead corners, and the garbage cleared should be burned in a centralized manner.

2. Cleaning: After cleaning the above-mentioned room and tools, wash them with clean water. The spots, corpses, excrement, cocoon silk, etc. left in the surface and gaps of the silkworm room and tools can be scraped off with a knife to eliminate the hidden dangers of silkworm diseases.

3. Painting: After sweeping and cleaning the walls and ceilings of the silkworm room, add 20% lime slurry to "Baikoteri" special disinfection and sterilization cleaning agent for breeding, and paint them all over. This can make the silkworm room white and beautiful and kill pathogens.

4. Soaking: Put the plastic cocoons, silkworm nets, plastic films, silkworm foils, silkworm racks and other small plastic, bamboo and wooden silkworm tools into the disinfection pool equipped with "Baikoteri" special disinfection and cleaning agent for more than 2 hours, then take them out and dry them in the sun.

5. Sterilization: After completing the above steps, set up the silkworm racks in the cocoon room and arrange all the silkworm tools. One day before raising silkworms, use the dry fog sterilization system of Biotech, and use the dry fog of "Batech" special disinfection and sterilization cleaning agent to kill bacteria, viruses, pathogens and harmful microorganisms in the ambient air. Close the doors and windows for more than 2 hours, and then open the doors and windows to remove the dirty air. Only then can the sterile silkworm room be completed. At the entrance to the silkworm room, set up disinfection and sterilization mats, special disinfection and sterilization pools, towels, and slippers. Wash hands and change shoes when entering the silkworm room.

Note: What is the disinfection and sterilization level?

According to the appropriate dosage (concentration) or intensity and action time of the disinfection factor to kill microorganisms, disinfection and sterilization methods can be divided into four levels of action.

1. Sterilization is a method that can kill all microorganisms (including bacterial spores) to achieve a sterilization guarantee level. Methods belonging to this category include: physical sterilization methods such as heat sterilization, ionizing radiation sterilization, microwave sterilization, plasma sterilization, and sterilization methods using disinfectants such as formaldehyde, glutaraldehyde, ethylene oxide, peracetic acid, and hydrogen peroxide. (Representative products include: Bioteri's special disinfectant)

2. High-level disinfection can kill various microorganisms and achieve disinfection effects by killing bacterial spores. This type of disinfection method should be able to kill all bacterial propagules (including Mycobacterium tuberculosis), viruses, fungi and their spores and most bacterial spores. Methods belonging to this category include: heat, ionizing radiation, microwaves and ultraviolet rays, as well as disinfection methods using disinfection factors such as chlorine, chlorine dioxide, peracetic acid, hydrogen peroxide, bromine-containing disinfectants, ozone, dibromohydantoin and other methylhydantoin compounds and some compound disinfectants. (Representative products include: Biotec's special disinfectant)

3. Medium-level disinfection is a disinfection method that can kill and remove various pathogenic microorganisms other than bacterial spores, including ultrasonic waves, iodine disinfectants (iodine tincture, etc.), alcohols, combinations of alcohols and chlorhexidine, combinations of alcohols and quaternary ammonium salts (including double-chain quaternary ammonium salts), phenols and other disinfectants.

4. Low-level disinfection methods, chemical disinfectants that can only kill bacterial propagules (except mycobacteria) and lipophilic viruses, and mechanical sterilization methods such as ventilation, flushing, etc. Such as single-chain quaternary ammonium salt disinfectants (benzalkonium bromide, etc.), biguanide disinfectants such as chlorhexidine, plant disinfectants, and metal ion disinfectants such as mercury, silver, copper, etc.

Dry fog sterilization method: It is mainly used for indoor air sterilization. Since the particles of dry fog are only 5-10 microns, the particles of sterilizer are easier to float in the air. It is currently the preferred solution for indoor air space disinfection and sterilization. The disinfection and sterilization are the most thorough (the best dry fog sterilization equipment is OFIM).

Wet fog sterilization method: Wet fog sterilization equipment is mainly used in outdoor environments, such as ground, sports field, passages, etc. Biotech sterilization equipment is developed based on the actual outdoor environment and this special application environment. The main principle is to atomize the particles of the sterilant to about 40-50 microns, so that it is not easy to float in the air, but it is easy to evenly adhere to the surface of the object, which can achieve the best disinfection and sterilization effect. (Wet fog sterilization method is produced by Biotech sterilization)
