Hi Kevin,
The photos have all been scored by an average of 7 different people so we're at a point now where we can begin to assign stages to the different cells. I hope to get a manuscript together this summer for publication in a scientific journal.
Our preliminary conclusion is that neither Apistan nor Rally, nor the combination of Apistan and Rally has any effect on brood development. So, it looks like a negative result -- though we need to redo the analysis now that more people have scored the photos.
We are preparing to take more photos of brood this summer, but may attempt to use computer image recognition to score the photos, but we will almost certainly still need manually scored photos to train and validate the image recognition software.
