Fig. 2.

Resistance allele frequencies at the 198 and 200 SNP positions in isotype 1 beta-tubulin from pooled samples of Wallangra larvae not exposed to thiabendazole, or populations of Wallangra larvae that had survived various levels of the drug in larval development assays; data was derived from sequencing reactions in the forward (A) or reverse (B) directions. Each column represents mean ± SE, n = 3 separate pooled larval samples. Within a SNP position, columns labelled with different letters are significantly different (P < 0.05).
