“…Two rRNAs, i.e., the small ribosomal RNA (rrnS) and large ribosomal RNA (rrnL), were 770 bp and 1366 bp in length, respectively. These lengths are similar to those of most reported hymenopterous insects 27 , 66 . These rRNAs were located on the heavy strand and were separated by trnA.…”

“…The total length of 22 tRNAs was 1481 bp, accounting for 9.44% of the whole A. fulloi mitogenome (Table 2 ). These tRNAs range from 60 to 71 bp, within the size range observed in hymenopteran parasitoids 17 , 27 , 42 (Table 1 ). Among these tRNAs, 12 tRNAs were coded in the heavy strand, and the remaining 10 tRNAs were identified in the light strand.…”

“…The high A + T content and presence of repeat regions may result in the failure of obtaining CR sequence due to the inhibition of DNA polymerase 40 , 71 . Currently, the long and complex control region still presents challenges to obtaining complete mitogenomes in certain groups of parasitoids 19 , 20 , 27 , 41 , 72 , 73 . In this study, we failed to obtain the complete segment of the CR by next-generation sequencing or Sanger sequencing.…”

“…The current morphology-based taxonomy of Anastatus is problematic due to early taxonomic confusion, low degrees of morphological differentiation, and morphological variation related to host and geographical origin 23 – 25 . Parasitoids within Chalcidoidea are some of the most diverse hymenopterous insects, exhibiting the characteristics of frequent gene rearrangement, high substitution rates, and a strong base composition bias in mitogenomes 26 , 27 . Although the mitogenomes of other hymenopterous insects have been applied for identification, evolution, and phylogeny, this is not the case for Anastatus parasitoids.…”

The genus Anastatus comprises a large group of parasitoids, including several biological control agents in agricultural and forest systems. The taxonomy and phylogeny of these species remain controversial. In this study, the mitogenome of A. fulloi Sheng and Wang was sequenced and characterized. The nearly full-length mitogenome of A. fulloi was 15,692 bp, compromising 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes and a control region (CR). The total A + T contents were 83.83%, 82.18%, 87.58%, 87.27%, and 82.13% in the whole mitogenome, 13 PCGs, 22 tRNA genes, 2 rRNA genes, and CR, respectively. The mitogenome presented negative AT skews and positive GC skews, except for the CR. Most PCGs were encoded on the heavy strand, started with ATN codons, and ended with TAA codons. Among the 3736 amino acid-encoding codons, TTA (Leu1), CGA (Arg), TCA (Ser2), and TCT (Ser2) were predominant. Most tRNAs had cloverleaf secondary structures, except trnS1, with the absence of a dihydrouridine (DHU) arm. Compared with mitogenomes of the ancestral insect and another parasitoid within Eupelmidae, large-scale rearrangements were found in the mitogenome of A. fulloi, especially inversions and inverse transpositions of tRNA genes. The gene arrangements of parasitoid mitogenomes within Chalcidoidea were variable. A novel gene arrangement was presented in the mitogenome of A. fulloi. Phylogenetic analyses based on the 13 protein-coding genes of 20 parasitoids indicated that the phylogenetic relationship of 6 superfamilies could be presented as Mymaridae + (Eupelmidae + (Encyrtidae + (Trichogrammatidae + (Pteromalidae + Eulophidae)))). This study presents the first mitogenome of the Anastatus genus and offers insights into the identification, taxonomy, and phylogeny of these parasitoids.

“…There are 22 tRNA genes, ranging from 62 to 72 bp in length, and all of them can be folded into typical clover-leaf secondary structure except for tRNA Ser (AGN) , the dihydrouridine (DHU) arm of which forms a loop, as is common phenomenon in most insects (Jiang et al 2016;Xu et al 2019;Wu et al 2020aWu et al , 2020b. The length of IrRNA and srRNA is 1,273 bp and 829 bp, respectively.…”

The Pentatoma semiannulata is an important fruit pest in Chinese agricultural system. In current study, the complete mitochondrial genome of P. semiannulata is determined. This mitogenome is 15,515 bp in size and comprises of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a control region. Gene order is identical to that of the putative ancestral arrangement of insects. All protein-coding genes initiate with ATN, except for ATP8, COX1 and NAD1 use GTG or TTG as the start codon, and terminate with TAA with the exception for COX2 which uses a single T residue as the stop codon. All tRNAs, ranging from 62 to 72 bp, have the cloverleaf structure except for tRNA Ser(AGN). The monophyly of Pentatomidae is highly supported by the phylogenetic tree and P. semiannulata is very close to other herbivorous species of the remaining Pentatomidae species.
