Subject: 98'th update on fly longevity experiments
This is the 98'th update of my fly longevity experiments. Average
temperature was 21.1 C during this run. Estimated maximal longevity using
the formula (363 - T*11.2) is 122 days.
Here I recheck previous "winners" such as loosetrife, oxymol, and
pomegranate. I also decided to try annatto. Since annatto toxicity is
known to be mediated by riboflavin deficiency, some riboflavin was added
to see if this would make any difference.
Annatto may have been slightly beneficial, but riboflavin did nothing.
Loosestrife, oxymol, and pomegranate all came up winners again, with
oxymol holding a significant lead.
