Fig. 3From: Evaluation of the evolutionary genetics and population structure of Culex pipiens pallens in Shandong province, China based on knockdown resistance (kdr) mutations and the mtDNA-COI genekdr haplotype networks showing the genealogical relationship for Cx. p. pallens. Each haplotype is represented by a circle with size proportional to its frequency in the sample. Different colors indicate different populations. Lines represent variable asynchronous numbers; black solid circles represent missing haplotypes. The note above the circle referred to the mutation position and base. H: haplotype. H01LFS represent H01-L, H01-F and H01-S; H02LFS represent H02-L, H02-F and H02-SBack to article page
