This is the 51'st update of my fly longevity experiments. All bottles
contain 1/4 tsp citric acid as a standard additive. Recorded average
temperature during the experiment was 25.9 C.
For this experiment I used an older breeding bottle, that had seen a
lot of mortality, and which I would expect to be heavily infected. Control
survival showed this batch was indeed suffering from the fly equivalent of
the black death. Only egg albumin failed to improve survival. Of the
supplements tested, rice polishings and soy protein offered the most
impressive results. Soy genistein is known to exert a strong antiviral
effect on at least some types of virus. Since soy protein is not
expensive, I've added it to some new batches of breeding bottles. My
eventual goal is to eradicate virus induced mortality.
