Drosophila feeding assays. Feeding was measured as 625 nm absorption owing to dye included in the test media. The ATPalpha ^CJ6 strain consumed significantly more media than controls and the positive control strain consumed significantly less. n = 2–3 groups per genotype, representing 60–90 animals. Error is standard deviation. * P < 0.01 and ** P < 0.001 (Student’s t test). All genotypes consumed a significant amount of media and their absorption was in the linear range of detection. Genotypes tested were young age-matched adults (days 3–5)
