测定了姬小蜂的线粒体基因组序列，这是姬小蜂科（膜翅目：小蜂总科）第一个完整的线粒体基因组序列。该线粒体基因组全长15，698 bp，包含37个经典的真核线粒体基因和一个富含A + T的区域。所有13个PCG开始都以典型的ATN密码子开始。其中，7个基因以TAA终止，1个以TA-终止，5个以T-终止。所有22个tRNA基因的大小在56 ~ 70 bp之间，除trnS 1的二氢尿苷（DHU）臂形成一个简单的环外，其余都具有典型的三叶草结构。基因的方向和排列与广管虫线粒体基因组相似。小蜂也有一个剧烈的基因重排，有些基因的位置是小蜂总科所特有的。系统发育分析高度支持小蜂总科和金小蜂科的单系性。
The mitochondrial genome of the Encyrtus infelix was sequenced and it is the first completed mitochondrial genome of species in the family Encyrtidae (Hymenoptera: Chalcidoidea). This mitochondrial genome is 15,698 bp in length with 37 classical eukaryotic mitochondrial genes and an A + T-rich region. All the 13 PCGs begin with typical ATN codons. Among them, seven genes terminate with TAA, one with TA- and five with T--. All of the 22 tRNA genes range from 56 to 70 bp with typical cloverleaf structure except for trnS1, whose dihydrouridine (DHU) arm forms a simple loop. Gene directions and arrangements are similar to Eurytoma sp. mitochondrial genome. Encyrtus infelix also has a dramatic gene rearrangement, the placements of some genes are peculiar to Chalcidoidea. Phylogenetic analysis highly supported the monophyly of both Chalcidoidea and Pteromalidae.
