Ikovnnikov (Orthoptera: Acridoidea) is one of the important pests in the grasslands in northern China. The complete mitochondrial genome of this insect was sequenced. This genome is 16,615 bp long, with an AT content of 73.3%, containing 37 typical animal mitochondrial genes and an AT-rich region. All 13 PCGs share the start codon ATN, and the usual termination codons (TAA) are found from 13 protein-coding genes. All of the 22 typical animal tRNA genes were found in mt-genome, and most of the tRNAs could be folded into the classic cloverleaf secondary structure except for tRNA-Ser (AGN), which lacks the dihydrouracil (DHU) stem. The sizes of the large and small ribosomal RNA genes are 1555 and 799 bp long, respectively. The AT content of the AT-rich region is 87.0%. Phylogenetic analysis supports that the coleopteran insects from the same family cluster in the same group.
伊科文科蝗（直翅目：蝗总科）是中国北方草原的重要害虫之一。对该昆虫的线粒体全基因组进行了测序。该基因组长度为16,615 bp，AT含量为73.3%，包含37个典型的动物线粒体基因和一个富含AT的区域。所有13个蛋白质编码基因（PCGs）均以ATN作为起始密码子，13个蛋白质编码基因均发现了常见的终止密码子（TAA）。在该线粒体基因组中发现了全部22个典型的动物tRNA基因，除了缺少二氢尿嘧啶（DHU）茎的tRNA-Ser（AGN）外，大多数tRNA均可折叠成经典的三叶草二级结构。大、小核糖体RNA基因的长度分别为1555和799 bp。富含AT区域的AT含量为87.0%。系统发育分析支持来自同一科的鞘翅目昆虫聚集在同一类群中。
