Abstract:Anaka burmensis Dworakowska is one of the important pests which feed on bamboo. To investigate the genetic variation among different geographic populations in China, a total of 241 A. burmensis individuals from 26 geographic populations were analyzed for 615 bp segments of the mitochondrial cytochrome coxidase subunit I (COI) gene using DNASP, MEGA ect. There were 546 conserved sites, 69 mutation sites, 33 haplotypes in the fragment; a high level of genetic diversity (haplotype diversity: 0.845; nucleotide diversity: 0.008 77) in the total population was detected, higher genetic differentiation (fixation index: 0.729 15) and a low level of gene flow (0.598 5) was apparent among different geographic populations. The differences of the Neutral test (Tajima’s D=﹣1.658 98, 0.10>P>0.05, Fu's Fs=﹣5.787, P>0.10) were not significant. The analysis of molecular variance showed no obvious genetic differentiation within populations (27.08%) with a high proportion of the total genetic variance attributable to variation among populations (72.92%). The results of the study concluded the genetic structure, which can provide a theoretical basis for future research in molecular biology and the control of this insect.
