How should the silkworm rearing room be disinfected when raising silkworms, and what are the precautions?
Silkworm rearing has a fairly long history; this practice already existed in ancient times. Nowadays many people on the market like to buy silk quilts, and in fact the price of silk quilts is very high, so raising silkworms in rural areas is also a good choice. After all, silk is a very large market and can also lead farmers to prosperity. How should the silkworm rearing room be disinfected when raising silkworms? What other precautions are there?
1. How should the silkworm rearing room be disinfected when raising silkworms?
1. Cleaning and washing is the foundation. Comprehensive and thorough cleaning and washing is the basis for eliminating pathogenic microorganisms of silkworm diseases, and can remove more than 70% of pathogenic bacteria and viruses.
2. Choose targeted disinfectant drugs to improve the actual disinfection effect. It is necessary to select targeted drugs and broad-spectrum disinfectant drugs for disinfection in separate rounds according to common local silkworm diseases, especially the characteristics of silkworm disease occurrence in the previous season, so as to improve the actual disinfection effect.
3. The physiological characteristics of the silkworm, its dense and open-style rearing form, and the pattern of silkworm disease occurrence from individual to population and from local to whole determine that silkworm rearing disinfection is different from some other disinfection. Its characteristics are as follows. Disinfection requirements are high. Silkworms are densely reared in a limited space, and it is inevitable that some individuals in the population will become diseased. Diseased individuals spread infection within the silkworm bed through feces, blood, and so on. The earlier diseased silkworms appear, the more serious the harm. Especially once disease occurs during the young silkworm stage, it is very easy to cause the spread and expansion of silkworm diseases later on. Therefore, it is not only necessary to carry out disinfection of the silkworm rearing room and silkworm tools before silkworm rearing with high standards and strict requirements, but also essential to attach great importance to disinfection of the silkworm body and silkworm bed during the rearing period and cleaning and disinfection after the end of each silkworm rearing period, running disinfection through the entire process of silkworm rearing production. Pathogenic microorganisms have strong resistance.
2. What are the precautions during disinfection?
1. Use of disinfectants
Formalin and bleaching powder liquid are corrosive. When preparing them, it is best to use a water vat or wooden bucket. To ensure drug efficacy, it is best to prepare them just before use and not leave them standing too long. In particular, note that bleaching powder liquid cannot be mixed with lime preparations. Each disinfection must maintain warmth and moisture.
2. Every place inside and outside the silkworm rearing room must be disinfected
Every piece of silkworm tool must not be missed in disinfection. The floor, roof, and wall corners must have no dead angles. Metal, fiber, and paper should not come into contact with disinfectant chemicals.
3. Issues to note after disinfection
After disinfection, the silkworm rearing room should not be opened at will, silkworm tools should not be moved outdoors for other uses, and they should not be rinsed with water. Undisinfected items should not be casually brought into the silkworm rearing room, so as to avoid pathogenic bacteria infecting the silkworm rearing room and silkworm tools. Keep all kinds of items properly.
4. Avoid fire
When the fumigant smoke disinfection firepower is too strong, it can emit flames of about 1 m. Therefore, the stove should be kept away from silkworm tools to avoid fire. If the indoor humidity is insufficient, white crystalline substances may appear on the silkworm tools. Strengthening ventilation can let them disappear naturally, or they can be wiped dry with a damp cloth.
