Effects of dietary eugenol treatment (0 or 50 ppm) on sugar water consumption by B. impatiens under (A) no-choice conditions in the Infection Intensity Experiment and (B) choice conditions in the Preference Experiment.
| A. No choice | χ2 | df | P |
|---|---|---|---|
| Eugenol | 1.174 | 1 | 0.279 |
| Time | 30.758 | 1 | <0.001 |
| Eugenol × time | 1.577 | 1 | 0.209 |
| Wing size | 5.908 | 1 | 0.015 |
| B. Preference | χ2 | df | P |
| Eugenol | 3.812 | 1 | 0.051 |
| Infection | 0.088 | 1 | 0.767 |
| Eugenol × Infection | 15.228 | 1 | <0.001 |
| Wing size | 18.118 | 1 | <0.001 |
Wing size refers to the length of the forewing marginal cell. Parasite selection regime in the no-choice experiment and time since inoculation in the preference experiment were not significant predictors of sugar water consumption. These terms were therefore removed from the final model.
