Table 4 Distribution of the Kdr genotype within An. gambiae M and S forms in Douala and Yaoundé

From: Anopheles gambiae distribution and insecticide resistance in the cities of Douala and Yaoundé (Cameroon): influence of urban agriculture and pollution

  An. gambiae molecular forms   Genotypes      
Kdrw/Kdrw Kdrw/KdrE Kdrw/S S/S Total F(Kdr) P(HW)
Douala M form 228 1 170 62 460 0.68 P = 0.002
  S form - - 1 - 1   
Yaoundé M form 79 0 124 115 318 0.44 P = 0.0003
  S form - - 2 - 2   
Total   307 1 296 177 781   
  1. S, wild type; Kdrw, L1014F substitution « West Africa"; KdrE, L1014S substitution "East Africa", Kdrw/S, heterozygote; P(HW), goodness of fit to Hardy Weinberg Equilibrium (significant if P < 0.05).
