| Strain | n | Mean slope (SE) | LC50 (95% CI) (μg/ml) | χ2 (df) | Resistance ratio | Da |
|---|---|---|---|---|---|---|
| Cornell strain (SS) | 350 | 3.69 (0.37) | 0.30 (0.26–0.33) | 3.31 (4) | 1.0 | |
| GLEN-BGII (RR) | 200 | NA | >440 | NA | >1,467 | |
| F1a (SS ♂ × RR ♀) | 300 | 2.71 (0.29) | 1.16 (0.96–1.38) | 2.46 (3) | 3.9 | −1 < D < −0.72 |
| F1b (RR ♂ × SS ♀) | 300 | 2.18 (0.26) | 0.95 (0.60–1.32) | 3.09 (3) | 3.2 | −1 < D < −0.76 |
