Efficacy of lambdacyalothrin-treated filter papers* to Anopheles gambiae from Ladji, Vkper (fixed for kdr allele) and Kisumu (susceptible) strains†

  Lambdacyalothrin 0.05% (18 mg/m2)–treated filter paper bioassays
  Strains  Slope (SE)  LT50 (95% CI)  LT50 ratio
  Ladji  2.1 (0.2)  10.9 (7.2–14.8)
  Vkper  2.1 (0.2)  14.2 (3.6–25.3)  1.3 (1.0–1.6)
  Kisumu  <1

*In World Health Organization kits.
†As determined by using probit analysis. kdr, knockdown; SE, standard error; CI, confidence interval; LT50 is the exposure time in min to kill 50%.
