This is the 89'th update of my fly longevity experiments. Average
temperature was 19.8 C during this run. Estimated maximal longevity using
the formula (363 - T*11.2) is 141 days.
Here I repeat run #75, which examined the effect of fly number per
bottle on longevity. That experiment found that longevity was best with
fly numbers below 10, though this result was not statistically
significant. The current run suggests that the previous result was due to
chance.
The 13 fly bottle has set a new record for "control" maximum
longevity, beating the previous record of 93 days set back in run #39.
