Metaflumizone is a novel sodium channel blocker insecticide, which has been registered for controling the diamondback moth (DBM), Plutella xylostella (Lepidoptera: Plutellidae) in China. It is unavoidable for DBMs to be exposed to sublethal dose of metaflumizone in brassicaceous vegetable field. Sub...

The utilization of sea-sand concrete (SSC) reinforced with glass fiber reinforced polymer (GFRP) bars presents a viable solution to address both the scarcity of river sand resources and the corrosion susceptibility of conventional steel reinforcement in marine environments. This study presents a fie...

Carboxylesterase (CarE) was considered as important phase-I detoxifying enzymes which participated in detoxification of different types of insecticides. Up-regulation of CarE genes has been proved playing a major role in insecticide resistance in many pest insects, but its involvement in resistance...

Differential effects of methamidophos and three pyrethroids on ATPase activity and membrane fluidity of mitochondria were investigated between the wolf spider (Pirata subpiraticus (Boes. et Str.)) and the rice stem borer (Chilo suppressalis (Walker)). Based on a comparison of LD50 values, the toxici...

The phenomenon of subsynchronous resonance (SSR) in multi-generator system is inherently complex and poses significant analytical challenges. This complexity arises primarily from the interactions among generators, particularly those sharing close torsional frequencies, which have not been sufficien...

The 7-ethoxycoumarin O-deethylase (ECOD) activities of cytochrome P450s and differential expression of six cytochrome P450 genes induced by the volatiles from both damaged and undamaged maize plants were investigated in the cotton bollworm, Helicoverpa armigera (Hübner). The ECOD activity changed wi...

ObjectiveTo investigate the molecular mechanism by which HMGA2 participates in the TGF-β/Smad pathway in the regulation of the proliferation, aggression, and metastasis of laryngeal cancer. MethodsshRNA transfection was used to construct the HMGA2 knockdown laryngeal cancer TU686 cell model, and sub...

IntroductionMyocardial bridge (MB), particularly involving the distal left anterior descending artery (LAD), presents unique challenges in percutaneous coronary intervention (PCI) when coexisting with proximal LAD stenosis. Drug-coated balloon (DCB) represents a “leave nothing behind” strategy that...

Carmine spider mites (Tetranychus cinnabarinus) and cotton aphids (Aphis gossypii) are both serious pests of cotton, and cause reductions in yields of this key agricultural crop. In order to gain insights into how plant defense responses induced by one herbivore species affect the behavior and perfo...

IntroductionMyocardial bridge (MB) is increasingly recognized for its potential role in coronary artery disease. However, its impact on lesion morphology and clinical outcomes in patients with left anterior descending (LAD) chronic total occlusion (CTO) undergoing intravascular ultrasound (IVUS)-gui...

The fall armyworm (FAW), Spodoptera frugiperda, is a newly invasive, widespread agricultural pest in China. Understanding the suitability of the main field crops in Chinese agricultural system as host for this polyphagous herbivore is especially important for making control strategy. Here, after FAW...

Background/purposeSide branch occlusion (SBO) remains a prevalent and clinically significant complication during percutaneous coronary intervention (PCI) for bifurcation lesions, particularly those involving the left anterior descending (LAD) artery. This retrospective study aimed to assess the inci...

Spodoptera frugiperda, the pest fall armyworm (FAW), is widespread in more than 100 countries. To date, planting insect-resistant transgenic crops is one of the main control methods in its native countries. In this study we evaluated Bt-transgenic maize (Bt maize) and non-transgenic (conventional) m...

In order to precisely assess gene expression level, a suitable internal reference gene must be chosen to quantify real-time reverse transcription polymerase chain reaction (RT-qPCR) data. For greenbug, Schizaphis graminum, a suitable reference gene for assessing the level of transcriptional expressi...

The whitefly Bemisia tabaci are considered as a taxonomically complex that contained some destructive pests. Two of the most prevalent cryptic species are B. tabaci Middle East-Asia Minor 1 (MEAM1) and Mediterranean (MED). In an extensive field survey of the B. tabaci complex present throughout part...

The cotton aphid, Aphis gossypii Glover (Hemiptera: Aphididae), is an important insect pest of cotton crops worldwide. The objectives of this study were to determine the acute toxicity of afidopyropen and whether there are any effects of sublethal concentrations of afidopyropen on the biological cha...

Carbohydrate chains are the principal antigens by which Bacillus thuringiensis (Bt) identify receptor proteins. The interaction between the antigen and Bt causes a pore in the membrane of midgut epithelial cells of insects. Receptor proteins, such as aminopeptidase N and alkaline phosphatase, are gl...

The gene expression and activity of (+)-δ-cadinene synthase during cotton development and in response to stress, as well as the spatial and temporal pattern of sesquiterpene biosynthesis, constitute one of chemical defense mechanisms in cotton plants. In order to explore the effects of omethoate on...

Sitobion avenae (F.) and Rhopalosiphum padi (L.) are two important pests of wheat in China. They typically coexist in fields during the late period of wheat growth. Sulfoxaflor is a novel sulfoximine insecticide that demonstrates broad-spectrum efficacy, especially in targeting sap-feeding insects....

The red imported fire ant (Solenopsis invicta) is a global major invasive pest, and has caused significant economic, social and environmental impacts since its invasion to mainland of China in 2004. To date, chemical control has been the most effective measure. However, the long-term use of chemical...
