Abstract: The present disclosure provides a warm water immersion-based hatching method of silkworm eggs, belonging to the technical field of sericulture production. In the present disclosure, a warm water treatment is conducted on silkworm eggs of a bivoltine silkworm variety in production, and a water temperature and an immersion time are optimized to ensure a higher hatching rate. The silkworm eggs are subjected to the warm water immersion at 49° C. to 51° C. for 15 s to 23 s to rapidly hatch the silkworm eggs without diapause.

Abstract: The present disclosure provides a warm water immersion-based hatching method of silkworm eggs, belonging to the technical field of sericulture production. In the present disclosure, a warm water treatment is conducted on silkworm eggs of a bivoltine silkworm variety in production, and a water temperature and an immersion time are optimized to ensure a higher hatching rate. The silkworm eggs are subjected to the warm water immersion at 48° C. to 51° C. for 15 s to 23 s to rapidly hatch the silkworm eggs without diapause. The method has a practical hatching rate reaching not less than 98%, with no adverse effect on a quality of silkworm cocoons, thereby achieving a same hatching effect as a hydrochloric acid hatching method but a low cost, simple operation, no need of hydrochloric acid, and green with no adverse effect on human beings and environment.
