UASt regulatory sequences drive expression of an inverted repeat.
Flies expressing ppk25GD1837 under the control of any of Scer\GAL4elav.PU exhibit courtship defects in the presence of (S,Z,Z)-CH503 (a more potent stereoisomer of the gustatory sex pheromone CH503).
Adults expressing ppk25GD1837 under the control of Scer\GAL4elav.PLu (in the presence of Dcr-2Scer\UAS.cDa to increase the efficiency of RNAi) do not show a significant defect in avoidance of noxious temperature (46[o]C) compared to control flies.
