Checked the survival of the late instar wax worms that were exposed to ClO2 gas for 24 hours and have since been able to recover for an additional 24 hours. Wax worms were checked to be alive or dead through prodding with a forceps. If they moved they were considered alive, if not then they were dead.
Results:
| Conc of ClO2 | Survival (n=15) |
| 10 mg | 15 |
| 100 mg | 15 |
| 200 mg | 3 |

| Survival of late instar WW after exposure to various concentrations of ClO2 gas |
Discussion:
All of the wax worms at the lower ClO2 concentration survived the exposure. However, the wax worms at the higher concentration (200 mg) did not all survive. Only 20% survived after only 24 hours of exposure. This is particularly interesting as at half the concentration (100 mg) all the wax worms survived. This study was only a preliminary examination of the effect of ClO2 on late instar wax worms, but it appears I may be close to the concentration at which the wax worms are just becoming susceptible to the gas. If I decide to continue with this experiment, I will repeat this experiment with more replicates.
