Laodelphax striatellus (Fallén, 1826) is one of key rice pests in Northeast Asia. We have determined the mitochondrial genome of L. striatellus collected in a mid-western part of Korean peninsula. The circular mitogenome of L. striatellus is 16,359 bp long including 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNAs, and a single large non-coding region of 1,972 bp. The base composition was AT-biased (77.3%). In comparison of the two Chinese L. striatellus mitogenomes with Korean mitogenome, total 140 and 40 single nucleotide polymorphisms and 166 and 118 insertions and deletions were identified, presenting intra-species variations based on geographical distribution.

A 16,359 bp mitochondrial genome of Laodelphax striatellus collected in a southern part of Korean peninsula was completed and their intraspecies variations were compared with Korean and Chinese L. striatellus mitogenomes. The circular mitogenome of L. striatellus contains 13 protein-coding genes, two rRNA genes, 22 tRNAs, and a single large non-coding region of 1,972 bp. The base composition was AT-biased (77.3%). It has only one single nucleotide polymorphism (SNP) in AT-rich region compared to other Korean mitogenome, but total 41 and 141 SNPs and 118 and 166 insertions and deletions, respectively, compared to two Chinese mitogenomes, suggesting the possibility of tracing migration based on geographic genetic diversity.
