Studies on the Emergence Ratio of Bombyx mori, between Cut off the Cocoon′s Edge Layer or not for Egg Production

종견의 절개와 발아율(탈견율) 간의 관계연구

In the silkworm egg production, cutting of the cocoon's edge formed by silkworms forced to aid the emergence, and emergence is related to the amount of alkaloid liquid in the sucking stomach in certain varieties. In this study, there was no difference between cutting of portion and sex, and no significant between cutting of both sides and one side cocoons when comparing their emergence ratio. Expenditures and emergence ratio between both sides and one side cutting off must be studied in coming future.
