Levels of Resistance to Pyrethroid among Distinct kdr Alleles in Aedes aegypti Laboratory Lines and Frequency of kdr Alleles in 27 Natural Populations from Rio de Janeiro, Brazil

Figure 1

Voltage gated sodium channel (Na_V) kdr alleles of Aedes agypti populations from Brazil. Schematic representation of the , with its four domains, each with six hydrophobic segments. The kdr sites 1011 and 1016 are in the IIS6 segment, while the 1534 site lies in the IIIS6. Each haplotype is represented by means of the variation at each kdr site, where wild-type and kdr aminoacids are indicated in black and red, respectively. The colours of the alleles are the same in the following figures.
