测定了油棕盾蚧Spilonota lechriaspis Meyrick（鳞翅目：卷蛾科）线粒体基因组的核苷酸序列。该序列全长15，368 bp，包含37个基因，具有典型的鳞翅目线粒体基因组序列。除tRNA（Ser（AGN））外，所有tRNA都可以折叠成典型的三叶草二级结构。蛋白质编码基因（PCG）具有典型的线粒体起始密码子，除了COI，它使用不寻常的CGA之一，发现在所有其他鳞翅目测序的日期。另外，13个PCG中有6个含有不完全终止密码子，1个T。富含A + T的区域包含一些与在其他鳞翅目线粒体基因组中发现的相似的保守结构，包括结合基序'ATAGA'的结构、19-bp的poly（T）延伸和三个微卫星（AT）（n）元件，所述微卫星（AT）（n）元件是较大的122+ bp大重复序列的一部分。这是首次报道鳞翅目昆虫线粒体基因组中的大重复序列。
We determined the nucleotide sequence of the mitochondrial genome (mtgenome) of Spilonota lechriaspis Meyrick (Lepidoptera: Tortricidae). The entire closed circular molecule is 15,368 bp and contains 37 genes with the typical gene complement and order for lepidopteran mtgenomes. All tRNAs except tRNA(Ser(AGN)) can be folded into the typical cloverleaf secondary structures. The protein-coding genes (PCGs) have typical mitochondrial start codons, with the exception of COI, which uses the unusual CGA one as is found in all other Lepidoptera sequenced to date. In addition, six of 13 PCGs harbor the incomplete termination codons, a single T. The A + T-rich region contains some conserved structures that are similar to those found in other lepidopteran mtgenomes, including a structure combining the motif 'ATAGA', a 19-bp poly(T) stretch and three microsatellite (AT)(n) elements which are part of larger 122+ bp macrorepeats. This is the first report of macrorepeats in a lepidopteran mtgenome.
