KDT₅₀: 50% knock down in mosquito’s population; KDT₉₅: 95% knock down in mosquito’s population.
^aThe KDT (KDT₅₀ and KDT₉₅) values were expressed with 95% confidence limits.
^bS = Susceptible defined as 98-100% of mortality; RS = Resistance suspected defined as 90-97% of mortality; R = Resistance defined as <90% of mortality.
