  1. KDT50: Knock down time for 50% of individuals (min). RR50: resistance ratio based on KDT50 values. RR50 values with CI95 intervals not overlapping those of both susceptible strains are shown in bold. For bendiocarb, % mortality after 10 min exposure is indicated with populations showing less than 50% mortality in bold. Bioassays were performed on Anopheles gambiae sensu lato adults.
