Migration trajectories of the diamondback moth Plutella xylostella in China inferred from population genomic variation

In temperate areas, annual populations of DBM originate from adult migrants. However, the source populations and migration trajectories of immigrants remain unclear. Here, we investigated migration trajectories of DBM in China with genome-wide single nucleotide polymorphisms (SNPs) genotyped using double-digest RAD (ddRAD) sequencing. We first analyzed patterns of spatial and temporal genetic structure among southern source and northern recipient populations, then inferred migration trajectories into northern regions using discriminant analysis of principal components (DAPC), assignment tests and spatial kinship patterns.</span></span></p> <p><span class="fontstyle01"><span><b>RESULTS:</b></span></span></p> <p><span class="fontstyle01"><span>Temporal</span></span><span class="fontstyle01"><span><b> </b></span></span><span class="fontstyle01"><span>genetic differentiation among populations was low, indicating sources of </span></span><span class="fontstyle01"><span>recipient </span></span><span class="fontstyle01"><span>populations and migration trajectories are stable.</span></span><span class="fontstyle01"><span> Spatial genetic structure indicated three genetic clusters in the southern source populations. Assignment tests linked northern populations to the Sichuan cluster, and central-eastern populations to the South and Yunnan clusters, indicating that Sichuan populations are sources of northern immigrants and South and Yunnan populations are sources of central-eastern populations. First-order (full-sib) and second-order (half-sib) kin pairs were always found within populations, but about 35-40% of third-order (cousin) pairs were found in different populations. Closely related individuals in different populations were in about 35-40% of cases found at distances of 900 to 1500 km, while some were separated by over 2000 km.</span></span></p> <p><span class="fontstyle01"><span><b>CONCLUSION:</b></span></span></p> <p><span class="fontstyle01"><span>This study unravels seasonal migration patterns in the DBM.
