This is the 60'th update of my fly longevity experiments. Average
temperature was 22.6 C during this run. Here I test some novel
supplements.
I was greatly surprised to see some white mold develop in the wild
rice bottle, despite the addition of citric acid to the fly food, to
assist the commercial mold inhibitor. Since the mold did not liquify the
food, the flies did not drown in it. This may be responsible the good
maximal longevity in this bottle.
Both walnut, and black rice look interesting, but replication of these
results would be required, before I could begin to take them seriously.
The control bottle had an unexpectedly poor survival.
