Fig. 1

Haplotype network and haplotype frequencies of Sogatella furcifera obtained from sampling seven regions in China and Southeast Asian counties. a Haplotype network based on mtDNA COI. Circles representing haplotypes are proportional to the number of individuals per haplotype. Each hatch mark along a connecting line represents a change of one base pair. b Haplotype frequencies and distribution in seven regions. The color of each haplotype was the same as the network. ArcGIS desktop (version 10.0, https://www.esri.com/software/arcgis) was used to produce a distribution map based on the geographical coordinates of the localities. The base map for the depiction was obtained freely from the URL: https://www.naturalearthdata.com/downloads/
