Male and female longevity was tracked for ten weeks in the low-dose experiment by placing 200 flies prior to adult emergence in replicate insect cages.

<p>Mortality rates were reduced in both sexes by sterilizing ionizing radiation. Hormetic conditioning only had a lifespan extension effect in males (<b>A</b>). Female longevity (<b>B</b>) was extended by irradiation but not further extended by hormetic conditioning. Means and standard errors across replicate cages are plotted in the graph.
