Figure 1From: Sodium channel point mutations associated with pyrethroid resistance in Chinese strains of Culex pipiens quinquefasciatus (Diptera: Culicidae)The distribution of collecting sites of Cx. p. quinquefasciat us. â‘ -â‘¥ indicated the six field strains of Cx. p. quinquefasciat us in China. RR was resistance ratio to deltamethrin, and the percentages were mutation frequencies of L1035F.Back to article page
