highly significantP-value < 0.0001
We observed a highly significant correlation between genetic (Fst) and geographical distances (Mantel’s test, P-value < 0.0001, S3 Fig ) between populations (sites) of B. tabaci SSA1 SG1 U SG2 (this Mantel test was not performed on B. tabaci SG3 or SSA2 ∪ SSA3 due to low sample sizes).
