| Medium 4 | 7.1 | 0 | 0 |
| Medium 5 | 6.0 | 0 | 0 |
| Medium 6 | 4.9 | 0 | 0 |

All media contained the same amounts of agar (16 g l−1), nipagin (12 ml l−1) and acetic acid (1.2 ml l−1). The control medium is used in Drosophila experiments as an ad libitum food source, and therefore contains much more nutrition than needed for successful development.
