Survival curves for the miRNA mutant females (backcrossed into the w[Dah] genetic background) kept as virgins or continuously exposed to SP-lacking (SP0) or SP-transferring (SP+) control males throughout their lifetimes. Shown are the survival curves for the (A) mir-278D knockouts, (B) mir-279D, (C) mir-317D hypomorphic mutant females, and (D) w[Dah] controls. For each panel, the virgins are shown by the dotted lines, females mated with SP+ males by the solid lines, and females mated with SP0 males by the dashed lines.
