Disentangling Taxonomic Confusions in the Group Using Mitochondrial Genomic Data (Lepidoptera: Pieridae).

Pierid species of the group are among the largest Sino-Himalayan members of genus , with four conventionally recognised species, namely , , , and . Recent publications indicated that some of these species may contain more than one species despite their similar morphological characters. The present research analysed this group of butterflies using mitogenomic data, and proved that , , , and should be recognised as distinct species, while , and should be subspecies of .

Host-plant adaptation in xylophagous insect-microbiome systems: Contributionsof longicorns and gut symbionts revealed by parallel metatranscriptome.

Adaptation to host plants is of great significance in the ecology of xylophagous insects. The specific adaptation to woody tissues is made possible through microbial symbionts. We investigated the potential roles of detoxification, lignocellulose degradation, and nutrient supplementation of and its gut symbionts in host plant adaptation using metatranscriptome.

Cradle for the newborn Monochamus saltuarius: Microbial associates to ward off entomopathogens and disarm plant defense.

The Japanese pine sawyer, Monochamus saltuarius, as a beetle vector of Bursaphelenchus xylophilus (pine wood nematode), is an economically important forest pest in Eurasia. To feed on the phloem and xylem of conifers, M. saltuarius needs to overcome various stress factors, including coping with entomopathogenic bacteria and also various plant secondary compounds (PSCs).

Gut Bacteria Associated With (Coleoptera: Cerambycidae) and Their Possible Roles in Host Plant Adaptations.

(Coleoptera: Cerambycidae) is an important native pest in the pine forests of northeast China and a dispersing vector of an invasive species . To investigate the bacterial gut diversity of larvae in different host species, and infer the role of symbiotic bacteria in host adaptation, we used 16S rRNA gene Illumina sequencing and liquid chromatography-mass spectrometry metabolomics processing to obtain and compare the composition of the bacterial community and metabolites in the midguts of larvae feeding on three host tree species: , var. , and Metabolomics in xylem samples from the three aforementioned hosts were also performed.

Description of a new species of Brullé (Hymenoptera, Stephanidae), with a key to the species from China.

A new species of the genus Brullé, 1846, Ge & Tan, , is described and illustrated from Guizhou Province, China. The key to all four species from China is included. A distribution map of the Chinese species is added.

The first record of the genus (Lepidoptera: Pieridae) from China.

Background: The family Pieridae is a large group of butterflies which plays an important role in evolutionary biology and contains many potential pests (Courtney 1986). Pieridae is a cosmopolitan family while the tropics harbour higher species richness. In a very recent expedition to the Chinese-Indian border area in Tibet Autonomous Region, a migratory species, (Fabricius, 1793), was discovered for the first time, which comprises the first record of the genus in China and the highest altitude record of this species.
