  1. S = L1014L, the susceptible allele. R = L1014F, the resistant allele.
  2. Frequency of L1014F resistance mutation (kdr-west); numbers of mosquitoes tested (n) and identified with susceptible and resistant alleles; and p-values for chi-square test of Hardy Weinberg disequilibrium (HWD) from mosquito samples collected by human landing in 2009 in three locations.
