Lethal dose (LD50, LD90) value of three insecticides against a laboratory strain C. lectularius using topical assays.
| Insecticide | * N | Model Parameters | Lethal Dose (ng/μL) | Model Fit | ||||
|---|---|---|---|---|---|---|---|---|
| ** Intercept ± SE | Slope ± SE | LD50 (95% CI) | LD90 (95% CI) | χ2 | df | p | ||
| Acetamiprid | 150 | −0.636 ± 0.162 | 1.509 ± 0.223 | 2.64 (1.78–3.80) | 18.64 (11.10–43.56) | 4.207 | 3 | 0.240 |
| Imidacloprid | 150 | −1.096 ± 0.220 | 2.873 ± 0.390 | 2.41 (1.92–2.94) | 6.73 (5.21–9.87) | 2.151 | 3 | 0.542 |
| Deltamethrin | 150 | 0.053 ± 0.188 | 1.156 ± 0.264 | 0.90 (0.55–2.78) | 11.49 (3.42–250.84) | 0.327 | 3 | 0.955 |
* Total number of treated insects with 30 insects in each concentration. ** The intercept and slope parameters are for models in which the independent variable is natural logarithm of dose.
