P insertion in the first intron of Blimp-1.
Blimp-1GS14751/+ mutants show significantly advanced timing of pupation compared to controls.
Expression of Blimp-1dsRNA.Scer\UAS driven by Scer\GAL4Act5C.PU results largely in lethality at pupal stages - some escapers (depending on the line used) die shortly after or during eclosion; introduction of Blimp-1GS14751/+ enhances lethality.
