Mid-Autumn Silkworm rearing "Five Preventions"

The first is to prevent low temperature and humidity. Low temperature and humidity are not conducive to the growth and development of silkworms, and are also likely to cause fungal disease outbreaks. Therefore, when the temperature is too low at night, it is necessary to appropriately perform temperature-warming and dehumidification. When heating, care should be taken to avoid the use of bald coal stoves to prevent silkworm gas poisoning.

The second is the occurrence of silkworm disease. In order to control the occurrence of silkworm disease in the later period, fresh lime powder plus extinction spirit is used once a day to disinfect the silkworm body of silkworm, and it has been used more than twice a day. Bacterial disease should be given antibiotics such as coleoptera. Strengthen the control of fly maggots, you can use the flies to add food or body spray. The time of administration was between 4 and 5 years, namely the third day of the fourth instar and the second, fourth, sixth and upper jaw of the fifth instar. The method of adding the food was: 500 ml of water per ml of silkworm flies was sprayed evenly on 5 kg of mulberry leaves. The body spray method is as follows: 300 milliliters of water per milliliter of silkworm flies solution is sprayed to the mulberry precursor, and the leaves are fed after the silkworm crawls.

The third is prevention of pesticide poisoning. It is necessary to prevent silkworm poisoning caused by pollution of rice, vegetables, pesticides, and industrial “three wastes”. Strengthen the mulberry leaf test feeding, after test feeding to ensure the normal use of leaves after non-toxic. Due to agricultural pest control and industrial pollution and other reasons, the poisonous and harmful substances in the air are gradually increased in the air, contaminating the mulberry leaves, and the silkworms are prone to cumulative poisoning after long-term consumption. It is recommended that the polluted mulberry leaves be sprayed or reclaimed in the field after clean water spraying. After rinsing with clean water, the heavily polluted mulberry leaves can be soaked and rinsed with 1% fresh lime water, dried and fed with silkworms to minimize the impact of pollution. In case of crop pest control, the silkworm room located under the crops should promptly close the doors and windows, prevent pesticide poisoning from causing silkworm poisoning, eliminate the smell of air pesticides, open the door and open windows for ventilation, and keep silkworm indoor air fresh.

The fourth is the prevention of silkworm enclosures. Large silkworm should strengthen ventilation in the latter part of the period. In low temperature weather conditions, coordination of ventilation and heat preservation should be done. When the temperature is normal during the day, more ventilation is required. When the temperature is too low at night, attention should be paid to scientific insulation or proper heating.

The fifth is the protection of silkworm heads. The dense silkworm nest not only causes scavengers, but also easily causes wounds and infects silkworm diseases. Therefore, it is necessary to pay attention to thinning silkworms and to prevent excessive density, so as to achieve two silkworms.
