Background: Chlorantraniliprole (CAP) is a diamide insecticide with high efficacy against many pest insects, including the black cutworm, Agrotis ipsilon. Agrotis ipsilon is a serious pest causing significant yield losses in crops. Glutathione-S-transferases (GSTs) belong to a family of metabolic enzymes that can detoxify a wide range of pesticides.

Article Synopsis
  • Glutathione S-transferases (GSTs) are crucial for detoxifying pesticides in insects, particularly in the economically important cigarette beetle (Lasioderma serricorne).
  • The study identified 14 GSTs in L. serricorne, with six genes significantly upregulated after exposure to the pyrethroid insecticide lambda-cyhalothrin (LCT), with LsGSTe1 showing the most substantial increase.
  • LsGSTe1 not only metabolizes LCT but also protects against oxidative stress; targeting this gene could enhance pest management strategies for controlling the cigarette beetle.

Chlorantraniliprole (CAP) is an insecticide widely used to control the small white butterfly (SWB), Pieris rapae. Exposure to CAP can cause oxidative injury in SWB; however, it is unclear if antioxidant enzymes are involved in the defense process. In this study, a thioredoxin peroxidase (PrTPX1) gene was identified from SWB by using a homology search method.

Beauveria bassiana has been widely used as an important biological control fungus for agricultural and forest pests, and clarifying the interaction mechanism between B. bassiana and its host will help to better exert the efficacy of the mycoinsecticide. Here, we proposed a novel pattern analysis (PA) method for analyzing time-series data and applied it to a transcriptomic data set of B.

Background: Cervicofacial space infections are potentially life-threatening, which require accurate diagnosis, early incision, and adequate drainage. The utilization of computed tomography (CT) in cervicofacial space infections has significantly increased for its advantages in the evaluation of abscesses, its availability, and low cost. However, the clinical value of preoperative CT imaging in cervicofacial space infections remains controversial for its poor specificity, radiation exposure, potential complications, and extra cost.

Extracellular vesicles can be released by almost all types of cells and are important mediators of intercellular signal transmssion. Extracellular vesicles regulate the function and activity of recipient cells by delivering biologically active molecules such as proteins and nucleic acids, which is of great significance in tissue repair and regeneration. According to numerous studies, extracellular vesicles derived from endothelial/endothelial progenitor cells can induce cell proliferation and differentiation, inhibit cell apoptosis, and promote angiogenesis, playing an increasingly important role in regenerative medicine.

Lambda-cyhalothrin (LCT) is a pyrethroid insecticide widely used to control insect pests. Insect exposure to LCT may cause abnormal accumulation of reactive oxygen species (ROS) and result in oxidative damage. Heat shock proteins (HSPs) may help protect against oxidative stress.

Article Synopsis
  • Plant essential oils, particularly trans-anethole from star anise, show potential as natural alternatives to synthetic pesticides due to their bioactivity against the green peach aphid, a major pest.
  • A comparative transcriptome analysis revealed 559 differentially expressed genes in M. persicae when exposed to a lethal dose of trans-anethole, with notable up-regulation of genes linked to ATP-binding cassette transporters, DnaJ, and cuticle proteins.
  • RNA interference studies showed that knocking down the ABC transporter gene (ABCG4) and a DnaJ gene (DnaJC1) significantly increased mortality in aphids, highlighting their roles in the insect's response to the toxicity of trans-anethole.

Article Synopsis
  • The green peach aphid, Myzus persicae, is a major agricultural pest globally, and this study focuses on the identification of the catalase (Cat) gene (MpCat) within this species, which is vital for protecting cells from hydrogen peroxide.
  • MpCat consists of 1515 base pairs, encoding a catalase protein with typical features found in other insects, including conserved amino acids crucial for enzymatic function, and its structure shows similarities to catalase genes in other aphid species.
  • The study found that MpCat is actively expressed throughout all developmental stages of the aphid, especially in adult forms, and its expression increases in response to environmental stressors, with RNA interference showing a significant impact on the survival of the aph

In this work, red quinoa was successively subjected to α-amylase steaming, complex enzyme Viscozyme (R) L hydrolysis, and lactic acid bacteria (LAB) fermentation. The total phenolic compound content (TPC), flavonoid content (TFC), and antioxidant capacities of the solvent-extractable (free) and bound fractions and the individual phenolic compounds released were determined. Compared to steaming with α-amylase, enzymatic hydrolysis and fermentation of quinoa resulted in approximately 82.

Article Synopsis
  • Insecticide exposure causes increased reactive oxygen species (ROS) levels and oxidative damage in insects, with superoxide dismutases (SODs) being crucial for protection against this damage.
  • A specific SOD gene (PrSOD1) was identified in the small white butterfly Pieris rapae, which shows strong antioxidant properties and is primarily expressed in larval stages.
  • Chlorantraniliprole, a commonly used insecticide, induces oxidative stress in P. rapae larvae, and the upregulation of PrSOD1 suggests it plays a significant role in combating this stress and may contribute to insecticide tolerance.

Dielectric properties of materials influence the interaction of electromagnetic fields with and are therefore important in designing effective dielectric heating processes. We investigated the dielectric properties (DPs) of pecan kernels between 10 and 3000 MHz using a Novocontrol broadband dielectric spectrometer in a temperature range of 5-65 °C and a moisture content range of 10-30% wet basis (wb) at three salt levels. The dielectric constant (ε') and loss factor (ε'') of the pecan kernels decreased significantly with increasing frequency in the radio frequency (RF) band, but gradually in the measured microwave (MW) band.

Entomopathogenic fungi and predatory mites can independently contribute to suppressing the two-spotted spider mite, Tetranychus urticae Koch. It is important to assess the risk of possible fungal infections in predators when a combination of them are being considered as a tandem control strategy for suppressing T. urticae.

In this study, two full-length cDNA sequences (Cmace1 and Cmace2) encoding putative acetylcholinesterases (AChEs) were cloned and characterized from the rice leaffolder, Cnaphalocrocis medinalis, an important lepidopteran rice pest in Asia. Cmace1 encodes a CmAChE1 consisting of 689 amino acid residues, while Cmace2 encodes a 639 amino acids CmAChE2. The two CmAChEs both have N-terminal signal peptides and conserved motifs including the catalytic triad, choline-binding sites, oxianion hole, acyl pocket, peripheral anionic subsite, and the characteristic FGESAG motif and conserved 14 aromatic amino acids.

In insects, rapid degradation of odorants in antennae is extremely important for the sensitivity of olfactory receptor neurons. Odorant degradation in insect antennae is mediated by multiple enzymes, especially the carboxylesterases (CXEs) and glutathione S-transferases (GSTs). The Asiatic rice borer, Chilo suppressalis, is an economically important lepidopteran pest which causes great economic damage to cultivated rice crops in many Asian countries.
