Abstract

A few smell deficient mutants of Drosophila have been characterized recently. In a series of experiments, we have compared the slow electrical response of the antenna (EAG) to calibrated concentrations of butanol and aliphatic n-acetates of olf C mutants with those of wild flies. This mutation was found to affect the dose-response curves specifically. Our data can be explained by assuming that this mutation affects the peripheral olfactory membrane at several levels.
