Abstract

Drosophila melanogaster adults were successfully selected for increased and decreased olfactory response to different concentrations of acetaldehyde and ethanol, using a choice type olfactometer. The response to selection was not concentration specific. Lines were also tested with n-propanol, n-butanol, acetic acid, propionic acid, benzaldehyde, methyl acetate, ethyl acetate and 3-hydroxybutan-2-one. The behavior of the lines was similar for most of these chemicals, indicating an odorant specific response to selection. However, ethanol selected lines differed in their response to n-propanol and possibly n-butanol, suggesting a role for the alcohol group in determining the specificity of gen..
