Courtship song in <i>Drosophila</i> <i>melanogaster</i>: a differential effect on male–female locomotor activity
Bibliographic record
Abstract
The courtship song of male Drosophila melanogaster Meigen, 1830 is involved in species recognition and sexual stimulation. This signal is usually addressed to the female to reduce her locomotor activity, thereby facilitating copulation. However, no accurate quantification of her locomotion has been made. To examine the effect of courtship song on locomotor behaviour of both sexes, we used a video-tracking system that allowed for the quantification of two indicators of activity level: distance moved and movement duration. First, we showed that the broadcast of the courtship song alone produced no effect on female locomotion. Females reduced their locomotor activity only when acoustical stimulation was placed in a natural courtship context (i.e., in the presence of a male). This suggests that the sum of visual, tactile, acoustic, and chemical stimuli provided by the male may act together to trigger female receptivity. Second, our playback experiments showed a strong stimulating effect of courtship song (particularly of the pulse component) on the locomotor activity of isolated males, suggesting that this signal probably plays a role in male stimulation. Courtship song has an opposite effect on male/female locomotor activity in D. melanogaster.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
