The fumigant toxicity of EOs on adults 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 | 5.3 (4.4–6.3) | 59.3 (41.1–97.1) | 1.57 ± 0.13 | 1.44 (4) | < 0.05 |
| 96 | 450 | 3.7 (3.0–4.5) | 47.6 (32.8–78.9) | 1.48 ± 0.13 | 1.70 (4) | < 0.05 | |
| C. limonum | 48 | 540 | 25.3 (18.7–38.5) | 636.0 (280.1–2,263.8) | 1.17 ± 0.13 | 0.41 (4) | < 0.01 |
| 96 | 450 | 12.0 (9.5–15.9) | 289.0 (149.7–764.0) | 1.19 ± 0.12 | 1.21 (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.
