Map of the distribution and relative abundance of the COI haplotypes in post-2013 SCA populations.

<p>Aggregation by state, the surface of the pie charts is proportional to the number of genotyped specimens. Haplotype network computed with Phyloviz (embedded figure left): the surface of the circles is proportional to the relative abundance of the haplotype, each node or step represents one base substitution, and the black dot corresponds to an unobserved haplotype. (a) data from Berlanga-Padilla et al. [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0196124#pone.0196124.ref028" target="_blank">28</a>]; (b) J.

Factorial components analysis of the genetic diversity of the 54 MLGs using genotypic data at nine microsatellite loci.

<p>The graph was produced with R scatterplot3D package [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0196124#pone.0196124.ref030" target="_blank">30</a>].</p

<p><b>Prevalence of MLL-C and MLL-D on different host plant species in Louisiana (A) and in the continental US (B).</b> A: Prevalence (number of samples bearing at least one specimen of each of the MLLs described in this study) of MLL-D and MLL-F in Louisiana among 2007 or post-2013 samples, according to host plant. B: prevalence of MLL-D and MLL-F in the continental US among post-2013 samples.</p

Minimum spanning network computed with Hapstar based on the genotyping at nine microsatellite loci.

<p>MLGs are either from the present study or from previous studies [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0196124#pone.0196124.ref014" target="_blank">14</a>,<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0196124#pone.0196124.ref016" target="_blank">16</a>]. Numbers within the circles refer to the MLG number according to [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0196124#pone.0196124.ref014" target="_blank">14</a>,<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0196124#pone.0196124.ref016" target="_blank">16</a>] and the present study. MLGs in the same colored box share the same COI haplotype: H1, H2 or H3. Haplotype H6, which was observed in two Ms50 specimens, is not represented. The steps between each MLL represent the number of allele differences.</p
