- N: Total number of mosquitoes exposed to each insecticides; KDT50 and KDT95: Knockdown time (minutes) for 50% and 95% of mosquitoes; CL 95%: 95% confidence limits; RR50: Resistance ratio at Kd50 level (KDT50 of wild population / KDT50 of susceptible strain); Mortality (%): mortality rate 24 h post-exposure; S indicates susceptibility; SR indicates suspicion of resistance that needs to be confirmed; R suggests resistance.
- For each insecticide, numbers with different superscript differ significantly at 5% level.
