Sericulture

Knowledge Title: Sericulture Other Title: silkworm rearing Knowledge Content:  The technology of producing silk raw materials, also known as silk breeding. The content includes the technical treatment of the production stages such as the breeding of silkworm species, the breeding of silkworms, the upper and the picking of silkworms. The aim is to ensure the healthy growth and development of silkworms, improve the yield and quality of silkworms, and reduce production costs. Modern silkworm sage is mainly to raise four sleeping generation hybrid species (see silkworm breeding). Usually 1 to 3 years called small silkworms or baby silkworms, 4 to 5 years called large silkworms or silkworms, small silkworms and silkworms have different physiological characteristics and breeding technical requirements. The number of silkworms raised each year depends on the length of the local mulberry tree: China's Yangtze River basin generally 4 to 5 times, according to the breeding season of spring silkworms, summer silkworms, early autumn silkworms, mid-autumn silkworms and late autumn silkworms; Before raising silkworms, plans should be made according to the conditions of mulberry leaves and silkworm chambers, silkworms and labor, and the number of annual feedings, the number of breeding periods and the date of ants collection should be determined.……

Silkworm disease

Knowledge Title: Silkworm disease Other Title: silkworm disease Knowledge Content:  Silkworms are highly susceptible to pathogenic microorganisms, parasites or other external factors under intensive group feeding conditions, which cause various diseases. Silkworm disease endangers the yield and quality of silkworms, and once it spreads, it will also lead to the failure of the whole silkworm business. In the middle of the 19th century, the European silkworm industry was devastated by particulate disease. France's L. Pasteur founded the mother's test in 1870 to control the spread of the disease. Since then, Japan, China and other places have also carried out scientific research on silkworm disease. Silkworm disease can be divided into infectious and non-infectious two categories. The former includes viral diseases, bacterial diseases, fungal diseases and pathogen diseases, the carcasses of diseased silkworms, feces, body fluids and silkworms contaminated with disease, silkworms, silkworms, mulberry leaves, etc.……

Veterinary Medicine

Knowledge Title: Veterinary Medicine Other Title: veterinary science Knowledge Content:  Study the science of preventing and treating diseases in livestock. The health and disease prevention and treatment of livestock, accompanying animals (e.g. dogs, cats, etc.), economic wildlife, experimental animals, ornamental animals, economic insects (e.g. bees, silkworms, etc.) and fish are all in the field of veterinary medicine. However, the research and prevention of fish disease, silkworm disease and bee disease in China are carried out by scientific research institutions of aquatic products, silkworm farming and beekeeping respectively. With the development of medical health, the scope of veterinary medicine has now been expanded to cover zoonotic diseases, public health, environmental protection, human disease models, experimental animals, food production, pharmaceutical industry and other fields, and formed a number of new marginal disciplines, agricultural production and the development of biology and human medicine has played an increasingly important role.……

Prevention and treatment of silkworm disease

Knowledge Title: Prevention and treatment of silkworm disease Other Title: silkworm disease control Knowledge Content:  Prevention-oriented. The basic method is: purify the environment of silkworm breeding, put an end to infectious diseases, strengthen breeding management, improve the physical fitness and disease resistance of silkworms, and try to avoid all kinds of conditions that induce silkworm disease. Prevention and control measures generally include: (1) strict disinfection. The disinfection of silkworm environment and silkworm chamber, silkworm, etc. shall be carried out according to the regulations by methods such as pharmaceutical, steam or high temperature. (2) Prevent the contamination of silkworms and contaminated mulberry leaves by disease-sourced and toxic substances (mainly pesticides and fluoride). Such as preventing breeders and feeding mulberry leaves into the source of disease, strengthening the pre-screening of silkworm disease, all clean water sources and special storage rooms in silkworm farms, strict management of silkworm sand and mulch.……
