In olfactory preference assays for polyamines, Ir75aMB00253/Ir75aMB00253 flies do not show any significant difference in their attraction to putrescine or cadaverine, as compared to wild type.
Ir75aMB00253/Df(3L)BSC415 ac2 sensilla have significantly reduced responses to acetic acid and propionic acid, but not to pyridine or 1,4-diaminobutane, compared to controls.
Sound-evoked compound action potentials in the antennal nerve are not significantly different from wild type in mutant flies. However, nonlinear mechanical amplification is significantly reduced compared to wild type.
