Figure 4. Under normal oxygen conditions, resveratrol extends lifespan in 9-day-old honey bees (Multi-group survival test: χ2 =11.72, df=2, N=130, P<0.01). Both 30 and 130 μM resveratrol treatments increased average lifespan in wild-type honey bees by 38% and 33%, respectively. Resveratrol treatments also lengthened maximum and median lifespan. Differences considered significant if P < 0.05.
