ScerGAL4fru.P1.B drives expression in a pattern that reproduces that of endogenous fru male-specific (fru[M]) isoforms.
Inhibition (using shits.FRT.stop.UAS at 30[o]C) of Scer\GAL4fru.P1.B neurons that also express Scer\FLP1ey.PU in adult females significantly reduces receptivity to mating, compared to controls; in males, courtship pulse song-induced locomotion is significantly reduced, compared to controls.
