Raising NEW VH2020 SILKWORM BREEDS IS BECOMING POPULAR IN VIETNAM.
The full name of the silkworm breed is “VH2020 Dual-System Quadruplex Hybrid Silkworm.” This is a hybrid product created from parent breeds originating from South Korea and Vietnam.
VH2020 silkworm breed has been recognized as a technically advanced silkworm breeds according to Decision No. 166/QD-CN-GVN dated May 19, 2023, by the Director of Department of Livestock Production, Ministry of Agriculture and Rural Development.
VH2020 silkworm breeds has an average cocoon yield of 12.53 kg of cocoon per 6-gram silkworm egg, with a single silk thread length of 800–900 meters, over 85% cocooning rate, and cocoon consumption of less than 7 kg per kilogram of raw silk.

Techniques For Breeding And Preventing Silkworm Diseases Include:
Hygiene, detoxification, and sterilization of silkworm rearing environment: silkworm breeds houses should be raised in elevated, well-ventilated, and clean conditions, away from rice fields, vegetable crops, pig, cattle, and chicken barns to avoid contamination. Foocmol 2% solution should be evenly sprayed on the entire floor area, walls, doors of the silkworm house, and rearing equipment before and after each rearing batch. The dosage is 2-3 liters of the prepared solution per 10 square meters of area.
Silkworm breeding equipment should be covered tightly after spraying to enhance antibacterial effectiveness. At least 4 hours after spraying, clean the silkworm house and rearing equipment with lukewarm water, then dry them in the sun before reuse.
Recommended to rear dual-system white mulberry silkworms like VH2020, which are generally heat-resistant, have good immunity, are less susceptible to diseases, and have high productivity and good cocoon quality. Attention should be given to storing and incubating eggs in cool and ventilated conditions and using protective measures to avoid predators like snakes, geckos, ants, and mice.
Hatching VH2020 silkworm eggs to silkworm breeding using different methods.
To achieve successful rearing, it is crucial to follow proper techniques: Provide appropriate mulberry leaves according to the silkworm’s age, avoiding feeding overly mature or immature leaves, which could lead to diseases. Properly store the mulberry leaves to prevent wilting or decreased quality. Monitor the temperature and humidity with a thermometer and hygrometer in the silkworm house.
In case of high temperatures above 30 degrees Celsius, take immediate measures to cool down the environment and increase humidity. Spray cold water on the floor and walls of the silkworm house, place several water pots inside, and use fans when necessary. Feed the silkworms at the right times and in sufficient amounts throughout the day and night to ensure even growth and maturity.

To ensure a successful silkworm rearing process and avoid losses, the following should be considered:
CAUSES OfFLOSS:
– Failure to properly detoxify the silkworm house and rearing equipment or improper detoxification, which results in residual pathogens from the previous batch, leading to silkworm diseases.
– Feeding silkworms with low-quality or contaminated mulberry leaves due to poor preservation or exposure to plant protection chemicals.
– Mishandling of silkworm hibernation, stopping feeding too early or feeding too much after awakening, causing hunger and weakening the silkworms, creating conditions for disease development.
– During rainy days, providing wet mulberry leaves to silkworms, poor ventilation in the silkworm house, direct sunlight in the west direction, and sudden temperature increase.
– Irregular use of disease prevention measures for silkworms.
PREVENTIVE MEASURES:
Thoroughly detoxify the silkworm breeding house and rearing equipment after each silkworm batch or before starting a new batch.
Feed silkworms with appropriate mulberry leaves for their respective ages. Harvest mulberry leaves on the day of feeding. Five-day-old silkworms require more mulberry leaves, so they need to be harvested in intervals to prevent wilting.
When silkworms are in hibernation, clean their excrement regularly, and let them hibernate under a thin layer of mulberry leaves. After awakening, sprinkle lime powder mixed with lime chloride to prevent diseases.
During rainy weather, provide dry mulberry leaves to silkworms and reduce the feeding amount. On sunny days, thin the silkworms and reduce the amount of mulberry leaves during the day, providing more food at night, and use fans for ventilation and western shade.
Regularly use disease prevention measures for silkworms at different stages of development. After spraying insecticides or applying nitrogenous fertilizers, harvest the mulberry leaves 20 days later before feeding them to silkworms.
If silkworms experience signs of poisoning, discard the old leaves, feed them with fresh and good-quality mulberry leaves, and spray sugar water (6 – 10%) on the leaves.
Currently, VH2020 silkworm breeding has achieved high productivity and excellent cocoon quality, and the products are guaranteed to be purchased at the best price by Nam Ban Silk silk yarn factory, bringing joy to farmers.
