“…Four complete and three nearly complete mitogenomes of Cephinae have been reported to date (Dowton et al ., ; Korkmaz et al ., , ). Here, the mitogenome characteristics of Cephinae were summarized by combining five new nearly complete mitogenomes representing two tribes: Hartigiini ( J. compressus , H. linearis and S. parreyssi ) and Pachycephini ( P. smyrnensis and P. cruentatus ).…”

A mitogenome dataset was produced representing three tribes and eight genera of Cephinae by adding seven previously sequenced species (Dowton et al ., ; Korkmaz et al ., , , ). A total of 13 mitogenomes was investigated to explore mitogenome evolution in Cephinae.…”

Cephinae represents one of the exclusively endophytophagous sawfly lineages with diverse host plant utilizations, in which most species have great economic importance. However, the evolutionary history of the subfamily has not been thoroughly investigated to date. Here, we characterized the mitogenomes of six species representing five genera of Cephinae. Rearrangements of the tRNA genes were found to be notably common. The rearrangements involve the IQM and TP gene clusters, and the former is a synapomorphy of the subfamily. In spite of the seldom occurrence of gene duplication in arthropods, three tRNA duplication events not known elsewhere in Symphyta were detected in Cephinae. The phylogeny of Cephinae was reconstructed using different datasets generated from mitochondrial genes and two nuclear fragments, EF‐1α and ITS2, under Bayesian inference (BI) and maximum likelihood (ML) approaches by adding the data of previously reported seven species. Five different tree topologies were recovered in which the tree produced from the nP12RNAexc4genes dataset under the BI and ML approaches was highly resolved with high support values. The phylogeny did not support the traditional tribal concept but it suggested two strongly supported clades. Diversification of the subfamily appears to correspond to a great extent to host plant availability and colonization in the Late Cretaceous, Early Eocene and Oligocene, suggesting speciation via host shift. The nonsynonymous substitutions and the most radical changes observed in mitochondrial protein‐coding genes were proposed as evidence for speciation driven by divergent adaptive selection.

The mitochondrial genome sequence of Tenthredo tienmushana (Takeuchi, 1940) (Hymenoptera: Tenthredinidae) (GenBank accession KR703581) was reported. The length of the sequenced region of this mitochondrial genome is 14,943 bp, with 13 protein-coding, two rRNA, 19 tRNA (the trnI, trnQ, and trnM were failed to sequence) genes and a partial A + T-rich region. As in most other sequenced mitochondrial genomes of the suborder "Symphyta", there is no gene rearrangement in the sequenced region compared with the pupative ancestral gene arrangement of insects. All protein-coding genes start with ATN codons. Eleven, one, and one protein-coding genes stop with termination codon TAA, TA, and T, respectively. Phylogenetic analysis using the Bayesian method based on all codon positions of the 13 protein-coding genes supports the monophyly of Tenthredinoidea. Two families of the Tenthredinoidea, i.e. Tenthredinidae and Pergidae, form the basal lineage of the Hymenoptera. Within the Tenthredinidae, the subfamily Tenthrediniinae and Allantinae form a sister lineage and then sister to the Nematinae. The Orussidae was recovered to be a sister group to the Apocrita, which contains Ichneumonidae and Vespidae in our analysis. The Cephoidea is sister to the lineage of Orussoidea + Apocrita.

“…All haplotypes discovered in this study were deposited in GenBank under the accession numbers reported in S1 Table. We aligned the resulting sequences with sequences obtained from complete sequencing of the mitochondrial genome of four species published by Korkmaz et al [50, 51]. Consequently, the COI sequences were aligned with a 264 bp portion and the 16S sequences were aligned with a 442 bp portion.…”

Phylogeography of the Wheat Stem Sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae): Implications for Pest Management

et al. 2016

The wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), is a key pest of wheat in the northern Great Plains of North America, and damage resulting from this species has recently expanded southward. Current pest management practices are inadequate and uncertainty regarding geographic origin, as well as limited data on population structure and dynamics across North America impede progress towards more informed management. We examined the genetic divergence between samples collected in North America and northeastern Asia, the assumed native range of C. cinctus using two mitochondrial regions (COI and 16S). Subsequently, we characterized the structure of genetic diversity in the main wheat producing areas in North America using a combination of mtDNA marker and microsatellites in samples collected both in wheat fields and in grasses in wildlands. The strong genetic divergence observed between North American samples and Asian congeners, in particular the synonimized C. hyalinatus, did not support the hypothesis of a recent American colonization by C. cinctus. Furthermore, the relatively high genetic diversity both with mtDNA and microsatellite markers offered additional evidence in favor of the native American origin of this pest. The genetic diversity of North American populations is structured into three genetic clusters and these are highly correlated with geography. Regarding the recent southern outbreaks in North America, the results tend to exclude the hypothesis of recent movement of damaging wheat stem sawfly populations from the northern area. The shift in host plant use by local populations appears to be the most likely scenario. Finally, the significance of these findings is discussed in the context of pest management.
