FEMALE SILKWORM LETHAL STRAIN OF BOMBYX MORI

摘要

Established and provided is a strain of an insect belonging to the order Lepidoptera, said strain being able to be easily maintained and managed without interrupting the genetic background thereof, being applicable to genetic modification technology and easily and arbitrarily allowing male-specific breeding within a short period of time.A female lethal strain can be obtained by transferring a gene expression vector, said gene expression vector encoding a mutated Masc gene that has cleavage resistance against Fem piRNA-Siwi complex and maintains the activity of the wild type Masc gene, into an insect belonging to the order Lepidoptera.
