Abstract
The genomic-level characteristics play a pivotal role as genetic assets for the identification of species and phylogenetic analysis. Here, we sequenced and analyzed the mitochondrial genome of Scambus vesicarius (Ratzeburg), which was first morphologically described in "Die Ichneumonen der Forstinsecten in forstlicher und entomologischer Beziehung." The motivation for this research arises from the necessity to comprehend the genetic composition and evolutionary history of S. vesicarius, a genus of parasitic wasps with potential agricultural significance, which. The circular genome is 26,103bp in length with an overall base composition of 42.02% for A, 43.71% for T, 8.64% for C, and 5.63% for G. The mitochondrial genome of S. vesicarius contained 13 protein-coding genes that initiated by the ATN codon, 22 transfer RNA genes, two ribosomal RNA genes (rRNAs), and a control region (CR). Phylogenetic analyses using Maximum-likelihood methods supported that S. vesicarius is closely related to Pimpla luctuosa, both of which belong to the subfamily Pimplinae, forming a clade that is sister to other subfamilies of Ichneumonidae. This study provides value not only into the genetic diversity and evolutionary history of S. vesicarius at the mitochondrial level but basic research on parasitic wasp biology and applied efforts in biological control.
