Table 4 Frequency (%) of Vssc mutations in dead and surviving Ae. aegypti mosquitoes from Jeddah from WHO bioassays with permethrin (0.75%), deltamethrin (0.05%) or DDT (4%) (order of mutations is 1016/1534/989, upper genotype is the base configuration: T = wildtype, G or C = mutant; lower genotype is the amino acid configuration; letters in parentheses refer to genotype code assigned in Fig. 2)

From: Voltage-sensitive sodium channel (Vssc) mutations associated with pyrethroid insecticide resistance in Aedes aegypti (L.) from two districts of Jeddah, Kingdom of Saudi Arabia: baseline information for a Wolbachia release program
