(Goodeniaceae) is an important evergreen coastal plant on islands in the South China Sea, which shows excellent tolerance for salty and drought conditions. Nevertheless, the growth of populations on these islands in the South China Sea has been threatened by a few serious insect pests. However, we know little about the biology of these pests.

The taxonomy of the superfamily Evanioidea from China has long been neglected, and the current status of their classification inhibits further research on their biology. This catalog updates and documents the genus- and species-level taxonomy for both extant and extinct species of the superfamily Evanioidea recorded from China, while providing information on type depositories and distributional data. Results from an extensive review of literatures, including host records and taxonomic notes, are also provided.

Scoliidae, also known as scarab hunters or flower wasps, are important in the biological control of scarabs and for pollination. Mitogenomic and phylogenetic studies are rare for this group. In this study, 10 mitochondrial genomes representing eight genera in two tribes of the family Scoliidae were determined.

Article Synopsis
  • Piperacillin is often used off-label to treat bacterial infections in neonates, and this study evaluated a dried blood spots (DBS) method for studying its pharmacokinetics in Chinese newborns.
  • Blood samples were taken from 24 neonates at set intervals and analyzed using advanced liquid chromatography to understand drug concentrations.
  • A population pharmacokinetic model was created, showing that specific dosing regimens based on postmenstrual age can achieve optimal effectiveness while minimizing the risk of toxicity.

Abnormalities in the extracellular matrix (ECM) play important roles in the regulation and progression of clear cell renal cell carcinoma (ccRCC). The cysteine cathepsin is one of the major proteases involved in ECM remodeling and has been shown to be aberrantly expressed in multiple cancer types. However, the clinical significance and biological function of distinct cysteine cathepsins in ccRCC remain poorly understood.

In Hymenoptera, the monophyly of Evaniomorpha has been the focus of debate among different scholars. In this study, we sequenced two mitochondrial genomes of (Hymenoptera: Megaspilidae) to analyze the mitochondrial genomic features of and provide new molecular data for phylogenetic studies of Evaniomorpha. The mitogenome sizes of and were 15,445 bp and 15,373 bp, respectively, with the of missing.

Species of Jurine, 1807 are a large group of parasitoids attacking leafhoppers, which are important insect pests. Despite their great potential in pest biological control, the taxonomy and biology of these parasitoids are far from clear. Sexual dimorphism is extreme in species and has hampered the taxonomy of these parasitoids, resulting in many species described based on a single sex.

Background: Data-independent acquisition (DIA) is one of the most powerful and reproducible proteomic technologies for large-scale digital qualitative and quantitative research. The aim of this study was to use proteomic methodologies for the identification of biomarkers that are over or underexpressed in women with intrahepatic cholestasis of pregnancy (ICP) compared with controls and discover a potential biomarker panel for ICP detection.

Methods: The participants included 11 ICP patients and 11 healthy pregnant women as controls.

Species of the family Scoliidae are larval parasitoids of scarabaeoid beetles and pollinators of various plants. Despite their great importance in pest biological control and plant pollination, the taxonomy and systematics of these parasitoids are far from clear. Some species of the family are extremely morphologically similar and difficult to identify, especially in males.

species have become one of the most commonly planted trees worldwide, including China, due to their fast growth and various commercial applications. However, the productivity of plantations has been threatened by exotic invasive insect pests in recent years. Among these pests, gall inducers of the genus of the Eulophidae family are among the most important invasive species in plantations.

The brown marmorated stink bug, (Stål) (Hemiptera: Pentatomidae), is native to northeast Asia. It was accidentally introduced to Europe and North America, where it has become a key pest, feeding on many important crops. Previous eco-climatic niche modelling indicates that could expand its distribution vastly, and numerous border interceptions of this pest in many countries, including Australia and New Zealand, indicate that it would be prudent to prepare for its eventual arrival.

The Scoliidae occur predominantly in tropical and subtropical regions and are ectoparasitoids of Scarabaeoidea larvae (especially of Melolonthinae) which are immobilised, parasitised by the female wasp in their terrestrial larval gallery and buried deeper in a special cell by the female wasp. Herein, we provided, for the first time, illustrated keys to 11 genera and 52 species of Scoliidae from China, based on specimens in the Naturalis Biodiversity Center (RMNH, Leiden) and additional specimens from the Chinese Academy of Insect Science (Beijing), Zhejiang University (ZJUH, Hangzhou) and Sun Yat-sen University (SYSU, Guangzhou) and it is a first attempt to make keys available for all the Scoliidae species in China.

The cotton mealybug Tinsley (Hemiptera: Pseudococcidae), is an emerging invasive insect pest in China. Hymenopteran parasitoids are the key organisms for suppressing populations of in the field, and therefore could be used as biological agents. Accurate identification of the associated parasitoids is the critical step to assess their potential role in biological control.

The genus Phanuromyia in the subfamily Telenominae (Hymenoptera: Scelionidae) consists of 60 described species, for which host records indicate they are egg parasitoids of lanternflies and planthoppers (Hemiptera: Auchenorrhyncha). In this study, we describe a new species of the genus, P. ricaniae sp.

Parasitic wasps largely rely on chemosenses to locate resources. Understanding the evolution of their chemoreceptors can help elucidate the mechanisms underlying host adaptation and speciation. Trissolcus basalis is a biological control agent of the southern green stink bug, a pantropical pest, and is ideal for investigating the evolution of chemoreceptors.

Background: Ashmead (Hymenoptera: Scelionidae) is a cosmopolitan genus of egg-parasitoid wasps associated with stink bugs (Pentatomidae, Scutelleridae, Urostylididae), many of which are important insect pests. Documentation of host associations for these wasps, which we here provide via museum specimens, can support their use as biological control agents of invasive stink bugs.
