- #Among the injected eggs, approximately 34% (152/450) and 37% (173/468) hatched to larvae in C2-3KO and N1-3aKO groups
- &Among the hatched larval, about 45% (68/152) and 43% (75/173) of the larvae developed into adults in G0
- *25 single-pair reciprocal crosses between the G0 progeny and the susceptible DBM1Ac-S were performed to produce G1 offspring
- †Among the 50 single pairs, 20/22 single pairs generate fertile progeny and one or two of the 20/22 single pairs showed mutagenesis in PxABCC3 and PxABCC2 or PxAPN3a and PxAPN1 locus by the specific PCR amplification
- ‡The other larvae from the single pair group with the positive mutation were reared to pupation, the gDNA samples from 70/80 exuviates of the fourth-instar larvae in C2-3KO/N1-3aKO group were used for nondestructive detection, and 30/35 of them were heterozygotes
- ¶18/24 homozygous individuals were determined by direct sequencing using the gDNA samples from 100/96 exuviates of the final fourth-instar larvae in C2-3KO or N1-3aKO group
