Measuring respiration rate in flies housed under laboratory conditions A highly significant gender effect on BM was observed, with female flies being significantly heavier ( F = 700.8, P < 0.001; Fig. 3 A) compared to males, although no significant treatment ( F = 0.589, P = 0.560) or sex × treatment interaction effect ( P > 0.05) was seen.
