Fussl was crossed with either Stinger (ctrl) or a UAS-TNT line to block the synaptric transmission of the Fussl positive neurons. A third construct was used but did not yield any data due to difficulties with their flight performance. The Fussl-Stinger along with Fussl-TNT flies do also show difficulties in flying. These differences will be assessed.

The experiment was done as a pilot experiment before doing a larger scale.

The data is a bit inconsistent but shows a positive and reassuring numerical difference. The control is a bit lower than expected, compared to WTB flies (showing usually a PI 0f 0.6). The flies have a slightly different background than wtb flies and have pale orange eyes (still no apparent impairments in vision). Further experiments will be conducted before proceeding with a larger sample size of the flies.
