No mortality was observed in the control group of each mosquito strain
LC_50,, LC₉₅ Lethal concentrations (50 and 95% mortality, respectively), C.I confidence interval, RR₅₀ resistance ratio at LC₅₀: LC₅₀ [resistant strain)/ LC₅₀ (Kisumu)], LCL lower confidence limit, UCL upper confidence limit, SE standard error
^aChi(P) is indicated to judge whether the data are well fitted to the regression or not. The fits are acceptable when the P-value is > 0.05
