The effects of diet type and antibiotic treatment (10 µg ml−1 ciprofloxacin and 200 µg ml−1 piperacillin) on the mean (s.d.) longevity in days of male (a) and female (b) Bactrocera minax. Unshaded bars are diets with no antibiotics added; shaded bars are diets with antibiotics added. Columns with the same letters are not significantly different after comparison with Tukey's test at p ≤ 0.05.
