Fig. 1From: Genetic diversity analysis of brown marmorated stink bug, Halyomorpha halys based on mitochondrial COI and COII haplotypesGeographical distribution of mtDNA COI haplotypes (657 bp fragment of the COI) of BMSB in native countries - (a) China, and (b) Japan. Provinces 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
