The Effect of Corona Artificial Incubation on Main Economic Characters of the Original and Stock Seed of Liangguang No.2
At present,the bivoltine silkworm eggs is mainly used in sericulture.Relieving the diapause of silkworm eggs and achieving the effect of artificial incubation are the foundation for achieving multi batch sericulture.Using the parents of Liangguang No.2 as materials,this study investigated the effects of corona induced hatching on the growth stages,robustness,cocoon quality,and egg laying of these silk-worm varieties.The results showed that the hatching rate of silkworm eggs treated with corona was simi-lar to that treated with HCl.After rearing the hatching eggs,we found that the age stages of the corona treatment group and the HCl treatment group were similar.The health of the corona treated group was better than that of the HCl treatment group,but the difference was not significant.The cocoon yield of the silkworm treated with Corona was higher than that of the silkworm treated with HCl,and some varieties showed significant difference.There was no significant difference between the two groups in the number of eggs laid by the original self-bred moth and the hybrid moth.These results proved that the corona artificial incubation technology had no adverse effect on the main economic characters of the parents of Liangguang No.2,and this technology can be applied to the parent silkworm rearing.
