Norpa/Crimson x Gr28bd/TrpA1 lines waited in vials which two of them include ATR and other two not. After doing T- maze experiment (at yellow light) their wings were clipped and next day Buridan test was done with them. This graph shows the stripe deviation of experimented flies. ATR dark(n=3), ATRlight(n=3),NoATRdark(n=4),NoATRlight(n=5). The result shows that experimented flies could not see and their motions were random.
