Single Larva Tracking

  • 1 mins
  • Director | Justin Blau

Double stimulus competition assay between odor attraction behavior and light avoidance behavior. Drosophila larvae are exposed simultaneously to an odor source (attractive) and a light gradient (repulsive) and have to decide whether to avoid light or crawl towards the odor source. 2 larvae per plate are filmed at 1 frame/second for 5min and their individual tracks are obtained using custom written image analysis software. The red larva displays predominantly odor attraction behavior whereas the larva in green displays predominantly light avoidance behavior.
