The fumigant toxicity of EOs on 10th instar of T. molitor
| EO | Treatment time (h) | Number of insects tested | LC50 (µl/liter) 95% CIa | LC95 (µl/liter) 95% CIa | Slope ± SE | Chi-square (df) | P* |
|---|---|---|---|---|---|---|---|
| L. cubeba | 48 | 450 | 4.5 (3.7–5.3) | 50.0 (35.0–80.6) | 1.57 ± 0.13 | 1.94 (4) | < 0.05 |
| 96 | 450 | 2.7 (2.3–3.2) | 22.2 (16.7–32.3) | 1.80 ± 0.15 | 3.05 (4) | < 0.05 | |
| C. limonum | 48 | 450 | 29.2 (21.1–46.5) | 781.3 (325.3–3,110.4) | 1.15 ± 0.14 | 0.51 (4) | <0.01 |
| 96 | 450 | 10.9 (8.8–13.9) | 209.2 (117.6–479.3) | 1.28 ± 0.12 | 0.84 (4) | < 0.05 | |

a LC50 or LC95 values are considered significantly different when the 95% CI do not overlap.
*Goodness-of-fit test is significant at P < 0.05.
