  1. Abbreviations: n  number of females tested, f (kdrw), L1014F kdr mutation frequency within each species, L1014F a mutated allele from leucine to phenylalanine at codon 1014 of the para sodium ion channel gene, SS wildtype genotype, RR homozygous mutation, RS heterozygote for the kdr gene
  2. Note: kdr mutation frequency do not differ significantly (P > 0.05) between dead and alive mosquitoes. Note that no L1014F kdr was detected. Frequencies were not calculated when the number of individuals tested was low (−)
