UASt regulatory sequences drive expression of an inverted repeat.
Expression of CCHa1GD8304 under the control of Scer\GAL4nSyb.PU (in combination with UAS-Dicer2 to increase RNAi efficiency) does not result in a significant change in the latency to sperm ejection in females after the end of copulation.
Expression under the control of Scer\GAL4pnr-MD237 may result in lethality before the pupal stage, depending on the insertion line used.
