Feeding Highlights of Autumn Silkworm Silkworms

The main reason for the instability of autumn silkworm production is the damage of silkworm diseases. With the increase of the number of silkworm rearing, the accumulation of the number of pathogens increases, the proliferation surface increases, the virus is fresh and breeds rapidly, and the pathogenicity rate is high. After using Jamsil and silkworm repeatedly, if the disinfection is not complete, and the feeding and management are relaxed, in addition to the bad conditions of high temperature, high humidity and high temperature drying in the autumn, and the poor condition of the mulberry leaves, the silkworm has weak disease. This is The main reason for silkworm disease outbreak is likely in the large silkworm stage in autumn.
First, strengthen disinfection and prevent disease, eliminate the source of the disease.
The effective measure to prevent silkworm disease is to eliminate the chance of infectious diseases through disinfection. In case of a silkworm disease, the disease source must be isolated immediately, lime or dry materials must be added, and the number of sand removal should be increased to prevent the spread. In the case of viral silkworm disease, fresh lime powder is used daily to disinfect silkworms and reduce the infection of silkworms. In the case of bacterial silkworm diseases, chloramphenicol can be added to prevent bacterial growth. If it is deadlocked, it can be used to disinfect silkworm body. In the case of myiasis, we can use the "diefly flies" spray or add food. When using a variety of agents, the standards and methods must be strictly controlled to achieve the effect.
Second, let go of food to prevent hunger.
The silkworm period requires a good grasp of the “three thins”, that is, the silkworm silkworms in the silkworm silkworms are loosened, the silkworm foils on silkworm silkworms are thinned, and the silkworm foils are thinned. In the autumn, when the temperature is high, when dry, the mulberry leaves can be sprayed with water to wet the leaves to feed silkworms, but the silkworms will not sleep or feed wet leaves when they are sleeping or mature. Wet leaves are moist with no drip. In addition, ventilation and ventilation have been strengthened. Sericultural farmers have the experience of “cultivation of autumn silkworm by air”. If there is no wind outside, fans can be used to circulate air. We must do a good job of resupplying Mulberry, especially during the food-giving period.
Third, to strengthen the treatment of sleep, strict mention of green in batches, autumn, mulberry leaves, old and gentle uniforms are not easy to sleep, with unhealthy silkworms, but also prone to sleep. If the sleep does not occur, they must be submitted to the village in batches to eliminate unhealthy and late-silkworms and silkworms. (Du Yingwu)
