Activities of detoxification enzymes in the midguts of SSB larvae fed on rice plants or artificial diet supplied with sodium silicate (SS)
| Treatments | Enzymes activities | ||
|---|---|---|---|
| AChE (U/mg∙prot) | GST (U/mg∙prot) | CYP450 (ng/ml) | |
| Control plants | 84.00 ± 2.810** | 53.27 ± 1.206** | 8.23 ± 0.130** |
| Plants with SS | 72.96 ± 1.547 | 45.85 ± 0.418 | 7.49 ± 0.112 |
| Control artificial diets | 25.420 ± 5.842* | 104.6 ± 13.860* | 16.730 ± 0.164* |
| Artificial diets with SS | 5.267 ± 0.188 | 63.880 ± 1.615 | 11.71 ± 1.733 |
Control plants: SSB larvae fed on the stems of rice plants without additional sodium silicate; Plants with SS: SSB larvae fed on the stems of rice plants treated with 2 mM sodium silicate. Control artificial diets: SSB larvae fed on artificial diets without adding sodium silicate; Artificial diets with SS: SSB larvae fed on artificial diets applied with 0.1% sodium silicate (w/w). Values are mean ± SEM (n = 5). The asterisk indicates a significant difference between two treatments (p < .05 using unpaired t test).
