Figure 6. DA contributes to the behavioral resistance to morinda carboxylic acids.
(A–B) Survival kinetic curves for D. melanogaster wild-type Berlin (wtB) (A) females (f, N > 3) and (B) males (m, N > 3) exposed to morinda carboxylic acids (OA:HA) and fed a standard diet supplemented with either no (−), or increasing doses of DA (5 mg/ml, 10 mg/ml and 100 mg/ml). *p < 0.02 and **p < 0.002 using Student's t test. (C–D) Survival (%) (N > 3) of D. sechellia (14021–0248.25, sec) and D. melanogaster wild-type Berlin (wtB) (C) females (f) and (D) males (m), fed a non-supplemented (−) or DA (+DA, 100 mg/ml) supplemented standard diet upon 2 hr exposure to morinda carboxylic acids (OA:HA). Different letters denote significant differences (p < 0.01) using ANOVA followed by Tukey's test. Error bars represent s.e.m.
