Odors elicit a number of behavioral responses, including attraction and repulsion in Drosophila. In this study, the authors used a T-maze apparatus to show that wild-type Drosophila melanogaster exhibit a robust circadian rhythm in the olfactory attractive and repulsive responses. These responses were lower during the day and began to rise at early night, peaking at about the middle of the night and then declining thereafter. They were also independent of locomotor activity.
