      Reference

      Obp28adel and Obp19adel homozygous mutant adults do not have gross defects in the size, morphology or position of basiconic sensilla, compared to controls; mutant ab5 and ab6 sensilla have no difference in their responses to odorants, compared to controls; mutant ab4 sensilla have stronger responses to linoleic acid, but not other odorants, and females have a shifted preference for oviposition on lower concentrations of linoleic acid, compared to controls.

      Obp28adel, Obp19adel and Df(3R)Obp83-ab homozygous mutant adults do not have gross defects in the size, morphology or position of basiconic sensilla, compared to controls; mutant ab3 sensilla have no difference in their responses to odorants, compared to controls.
