The present protocol assesses the locomotor activity of Drosophila by tracking and analyzing the movement of flies in a hand-made arena using open-source software Fiji, compatible with plugins to segment pixels of each frame based on high-definition video recording to calculate parameters of speed, distance, etc.

The method is based on open source software to systematically evaluate the local motor activities for the tracking behavior of adult and the larvae flies from recorded video. This method requires low cost device integration to record and analyze behavior, making it an affordable and effective approach for screening fly locomotion. This technology is employed to identify behavioral modification in a fly model of human disease with local motion impairment, but it is not suitable for treating disease, disabilities, or difficulties.

It is essential to clear the relevant video window during the analysis process, namely the original and the processing video window. To begin, mix reagent A and reagent B of the silica kit at a ratio of one to 10, according to the manufacturer's instructions, to prepare the open field arena for drosophila locomotion tracking. Next, set the HD camera on a tripod, adjusting it so that the camera lens is perpendicular to the surface of the silica arena.
