Synergistic effect of three synergists and sulfoxaflor on S. furcifera.
| Strain | Treatment | LC50 (µg/mL) 95%CI | Slope ± SE | χ2 (df) | SR * |
|---|---|---|---|---|---|
| Sus-Lab | sulfoxaflor | 3.544(3.287–3.804) | 6.499 ± 0.722 | 11.226(13) | / |
| sulfoxaflor plus TPP | 2.371(2.051–2.700) | 3.253 ± 0.418 | 4.864(13) | 1.495 | |
| sulfoxaflor plus DEM | 2.940(2.627–3.282) | 4.069 ± 0.512 | 4.997(13) | 1.205 | |
| sulfoxaflor plus PBO | 2.927(2.549–3.212) | 6.893 ± 1.199 | 10.213(13) | 1.211 | |
| SF-Sel | sulfoxaflor | 7.284(6.265–8.385) | 4.101 ± 0.454 | 14.726(13) | / |
| sulfoxaflor plus TPP | 2.709(2.180–3.449) | 1.972 ± 0.248 | 4.292(13) | 2.689 | |
| sulfoxaflor plus DEM | 3.191(2.529–4.061) | 2.200 ± 0.307 | 3.268(13) | 2.283 | |
| sulfoxaflor plus PBO | 1.367(1.129–1.648) | 2.829 ± 0.353 | 4.908(13) | 5.328 |
* SR (synergism ratio) = LC50 of a strain treated with sulfoxaflor alone divided by LC50 of the same strain treated with sulfoxaflor plus a synergist. The synergists of TPP, DEM and PBO stand for triphenyl phosphate, Diethyl maleateand piperonyl butoxide, respectively.
