Effects of piperonyl butoxide on the mortality of pyrethroid-resistant 2- to 5-day-old F1 Anopheles funestus s.l. mosquitoes in southern Zambia, 2015
| Study site | Deltamethrin alone | PBO + Deltamethrin | Student’s t-test | |
|---|---|---|---|---|
| % Mortality (n) | % Mortality (n) | t-value | P-value | |
| Buleyamalima | 27.0 (100) | 100 (60) | 24.33 | 0.001* |
| Gwembe Valley Development Centre | 13.8 (100) | 100 (50) | 54.39 | 0.001* |
| Chiyabi | 28.0 (32) | 100 (40) | 52.28 | 0.012* |
| Manchanvwa | 52.0 (50) | 100 (50) | 12.00 | 0.053 |
| Sikaneka | 42.3 (26) | 100 (50) | 7.667 | 0.083 |
| Siatwinda | 23.1 (52) | 100 (50) | 19.98 | 0.032* |
PBO = piperonyl butoxide.

P < 0.05, paired Student’s t-test was used to compare An. funestus mortality with deltamethrin alone and when combined with PBO.
