Supplemental Maltose or Glucose Increases Resistance to Peroxide. Females of three different DGRP lines were allowed to feed on media containing 2% glucose with the indicated amount of supplemental maltose (a). b Mated females fed on glucose food containing 2% of either additional maltose, additional glucose, or additional lactose, or control without additional carbohydrate for four days prior to being transferred to 2% glucose food containing 2% H₂O₂ for survival analysis. Points are the mean lifespans (± 1 s.e.) of 49 to 60 flies. ANOVA was used to compare the effect of maltose (P = 0.0035) after removing the effect of line in (a). The log-rank test was used in (b) to test the difference between lifespans of carbohydrate-fed verses control flies (asterisk, Bonferroni-corrected P ≤ 0.05)
