Table 2. Resistance ratio (RR95) of mosquito populations ( Anopheles gambiae) to bendiocarb, malathion, and pirimiphos-methyl.
CI95: confidence interval at 95%; KdT95: knock down time of 95% of the population; KdT95 of the wild strain divided by KdT95 of the Kisumu reference strain; RR95: resistance ratio at 95%.
