Traits measured on treated and untreated A. tabida individuals for all antibiotics
| Antibiotics | Mean (±SE) of sex-ratio offspring of males (no. tested) | Mean (±SE) of female locomotor activity rate (no. tested) | Mean (±SE) of female tibia length, mm (no. tested) |
|---|---|---|---|
| Untreated control | 0.811 ± 0.015 (16) | 0.561 ± 0.021 (30) | 0.705 ± 0.004 (35) |
| Rifampicin | 0.798 ± 0.009 (13) | 0.538 ± 0.024 (29) | 0.712 ± 0.006 (30) |
| Tetracycline | 0.846 ± 0.008 (12) | 0.504 ± 0.111 (27) | 0.714 ± 0.005 (28) |
| Ciprofloxacin | 0.811 ± 0.018 (11) | 0.563 ± 0.081 (24) | 0.716 ± 0.006 (28) |
| Gentamicin | 0.808 ± 0.017 (12) | 0.595 ± 0.123 (24) | 0.707 ± 0.005 (32) |
| ANOVA | F4,59 = 1.578 | F4,129 = 2.271 | F4,148 = 0.803 |
| P = 0.192 | P = 0.065 | P = 0.525 |
Sex ratio is the proportion of females. Statistical analysis was performed by one-way ANOVA (after transformation for sex-ratio offspring of males and for female locomotor activity).
