Detailed Explanation of Silkworm Egg Surface Disinfection Technology, a Must-Read for Silkworm Farmers

For spring silkworm eggs, disinfection is best carried out 1 to 2 days before hatching. For autumn silkworms, it is best done on the afternoon 1 day before hatching, and on that same day the eggs are taken directly to the mountain to hatch. First, bathe the eggs in a 0.5% sodium hydroxide aqueous solution at a liquid temperature of 18 to 20°C, washing the eggs for 1 minute to remove the adhesive material on the egg surface.
