Network of Trioza erytreae haplotypes. Median-joining network of cytochrome c oxidase subunit 1 (COI) gene (607 bp) of Trioza erytreae (n = 89), showing the relationships between haplotypes according to geographic origin and plant host. The size of the circles is proportional to the number of individuals sharing the same haplotype. The length of the branches is proportional to the number of nucleotide substitutions between haplotypes. Numbers along branches indicate the number of substitutions between haplotypes.
