ABSTRACT
The nearly complete mitochondrial genome of Trichiosoma vitellina is 15,245 bp long. It has the A + T content of 81.6% and contains 13 protein-coding genes (PCGs), 22 tRNA genes, and 2 rRNA genes. Gene rearrangement is present in the mitogenome of T. vitellina. All PCGs use standard ATN as start codons, and most PCGs have complete TAN as stop codons. Phylogenetic analysis demonstrates the position of T. vitellina in the Tenthredinoidea. This study provides essential data for the conservation genetics of T. vitellina and advances the understanding of the phylogeny of Cimbicidae.
ABSTRACT
We assembled the near-complete mitochondrial genome of Colochela zhongi Wei, 2016 with next-generation sequencing (NGS). The total genome size of C. zhongi was 15,095 bp with 80.6% A + T content, containing 13 protein-coding genes (PCGs), 22 tRNA genes, and two rRNA genes. Three tRNA genes rearrangements were found compared to the ancestral organization. Phylogenetic analysis results based on heterogeneity models of 46 Symphytan and two Apocritan strongly supported that C. zhongi was closely related to Siobla xizangensis.
ABSTRACT
Gilpinia infuscalae Wang Wei, sp. nov. (Hymenoptera: Diprionidae) from China is described. It is similar in color to G. nigra Okutani, 1958 from Japan but differs in the strongly infuscate wings, the simple inner spur of hind tibia and the unique lancet. The host plant is Pinus massoniana Lamb. (Pinaceae). A key to known species of Gilpinia from China is provided.

A direct cyanation of terminal alkynes for the synthesis of propionitrile derivatives, with the aid of silver salt using water additive, has been achieved. The cyano source used is N-isocyanoiminotriphenylphosphorane, which is nontoxic, safe, and easy to handle. This protocol is characterized by its operational simplicity, high efficiency with excellent yields, broad substrate scope, and greater functional group tolerance.
