Phylogenetic tree of 52 Thrips tabaci strains using the COI gene sequences. The COI gene sequences were obtained through nucleotide sequencing of the PCR products (42 strains other than HKD1, HKD2, HKD3, ANO, TOK6, WKY-M918T, TKO, TKO-SPRR, KTF-SPSS, and KTF-SPRR) and whole genome resequencing data (10 strains other than 42 strains examined using the PCR products). The tree was constructed with the Neighbor-Joining tree method using Molecular Evolutionary Genetics Analysis (MEGA) ver. 10.0. Bootstrap values on nodes were obtained by 1000 replications.
