X-Message-Number: 28004 Date: Thu, 1 Jun 2006 23:44:43 -0700 (PDT) From: Doug Skrecky <> Subject: 226'th update on fly longevity experiments This is the 226'th update of my fly longevity experiments. Average temperature was 23.9 C during this run. Estimated maximal longevity using the formula (363 - T*11.2) is 95 days. This run attempts to test the effect of heavy water on fly longevity. The only source of heavy water that could be purchased without coming under RCMP scrutiny turned out to be Jane Iredale's D20 spritz. This product includes some herbal extracts, plus some potassium sorbate. The later item is known to be toxic to flies at high dosages, as shown in run #200. There was no significant effect of this source of heavy water on longevity.
