Abstract: Different host populations of D. helophoroides is quite similar in morphology, while they prefer their originating hosts and show weak preference for other host. The mtDNA-COI and mtDNA-ND5 genes were used to investigate the intraspecific genetic divergence among six host populations of D. helophoroides in China. As per the COI sequences, intra-population variation accounted for 75.6% of tht total variation, obvoiusly higher than inter-popuation variation, with an Fst value of 0.24358. And as per the ND5 sequences, intra-population divergence covered 88.1% of the total divergence, significantly higher than inter-population divergence, with an Fst value of 0.11861.

Key words: Dastarcus helophoroides, COI, ND5, host population, haplotype, genetic differentiation
