Fig. 2From: Genetic diversity analysis of brown marmorated stink bug, Halyomorpha halys based on mitochondrial COI and COII haplotypesGeographical distribution of mtDNA COII haplotypes (518 bp fragment of the COII gene) of BMSB in native countries in the current study – (a) China, and (b) Japan. Regions where BMSB was collected from are shaded in grey. The size of pie is proportional to the frequency of haplotypes. Each colour represents a different haplotype. The figure was generated using Tableau 2019 (https://www.tableau.com/) [34]Back to article page
