Prolonged Sublethal Imidacloprid Exposure Reduces the Functional Response and Searching Efficiency of Orius similis Against Frankliniella occidentalis

ABSTRACT Neonicotinoid residues can compromise biological control in integrated pest management, yet the role of exposure duration is rarely quantified for predatory bugs. Here, we compared short‐term (24 h) and long‐term sublethal exposure to imidacloprid (LC 10 and LC 20 ) on t...

Integrated metabolomic and proteomic profiling reveals density-dependent variation in development and chemical composition of queen bee larvae

Queen bee larvae (QBL), a byproduct of royal jelly production, are gaining prominence as a functional food due to their health-promoting effects. Beekeepers routinely adjust queen cell numbers per colony to maximize the yield of royal jelly during commercial production, yet the i...

Property rights and the provision of rural public goods: evidence from China’s rural collective property rights system reform

Property rights reform is expected to mobilize multiple actors to actively participate in rural governance, thereby exerting an important influence on the provision of rural public goods. This study examines the impact of China’s Rural Collective Property Rights System Reform (RC...

From Cotton to Wheat–Maize: Farmer Decision-Making and Cropping Structure Transformation in a Smallholder County of China

Adjusting cropping structure is a key way smallholder agriculture adapts to changing labor availability, production costs, mechanization, and agricultural services. Most studies explain such change through macro-level factors—prices, policies, and resource endowments—and pay less...

OsWOX13 functions as a heading signal transducer from integrator Ehd1 to florigen for the accurate regulation of rice heading date

Abstract Appropriate heading date is an important safeguard for stabilizing rice yield and quality. Heading integrator Ehd1 and florigen Hd3a are crucial for rice heading. However, the mechanism by which Ehd1 transmits heading signals to Hd3a and the accurate regulation of Hd3a e...

Vanillin Improves Antioxidant Capacity, Immunity, and Gut Microbiota in Broilers

Wle vanillin is widely used as a flavoring agent in food products, its potential as a non-antibiotic feed additive for broilers remains unexplored. This study primarily investigated the effects of dietary supplementation of vanillin on antioxidant activity, anti-inflammatory resp...

Prolonged exposure to atrazine through drinking water facilitates splenic apoptosis and induces exhaustion-like checkpoint upregulation in mice

Atrazine (ATR) is a widely used herbicide that persists in aquatic environments, raising concerns regarding its long-term immunotoxicity. As a central immune organ, the spleen represents a potential toxicological target, yet the impact of prolonged ATR ingestion via drinking wate...

Height-Based Stratification in Greenhouse Harvesting Robotics: A Review from Ground-Level to High-Wire Crops

Labor shortages and the push for higher greenhouse efficiency have accelerated interest in automated harvesting. However, the development of a universal harvesting robot has been constrained by large variations in crop architecture, especially plant height. In this review, a heig...

Firmness Variation in Tomato Fruit: Driving Factors, Signaling Regulation, and Genetic Basis

Fruit firmness is a pivotal agronomic and commercial trait that determines the storability, transport tolerance and edible quality of tomato (Solanum lycopersicum L.). Fruit softening severely restricts postharvest performance and economic benefits of tomato products worldwide. T...

Household composition and adult-equivalent scales for food consumption expenditures in rural area of China

Purpose Establishing adult-equivalent (AE) scales for rural household food consumption expenditures is crucial for policymakers to set unified benchmarks for living costs in rural China. This study aims to estimate AE scales for food expenditures, providing a standardized tool to...

Effective Strategies for Controlling Ammonia Volatilisation Under the Mode of Replacing Chemical Fertilisers With Biogas Slurry

ABSTRACT Biogas slurry can effectively replace chemical nitrogen fertilisers by drip irrigation, but its high ammonia nitrogen content leads to ammonia volatilisation. This study investigated the effects of drip irrigation methods (surface vs. subsurface) and biogas slurry substi...

Akkermansia muciniphila attenuates Brucella infection: TLR4−associated inflammatory regulation and gut microbiota remodeling

Akkermansia muciniphila ( A. muciniphila ) is a promising next-generation probiotic with well-established beneficial effects on metabolic disorders, inflammatory diseases, and host immunity. However, whether A. muciniphila protects against Brucella infection remains unknown. Here...

Enzymatic Characterization of a Novel GH3 β-Glucosidase from Lentilactobacillus buchneri: EDTA-Mediated Enhancement of Thermostability

Background/Objectives: β-Glucosidases from lactic acid bacteria are valuable biocatalysts for carbohydrate conversion, flavour enhancement, and bioactive glycoside biotransformation. Although GH3 family enzymes have been characterized from several Lactobacillus species, no system...

Spatially contrasting CO 2 dynamics driven by green manure intercropping in subtropical tea plantations

Abstract. Tea plantations are important contributors to greenhouse gas emissions due to intensive fertilization and continuous cultivation. However, the mechanisms by which green manure intercropping regulates soil CO2 dynamics in these systems remain poorly understood. We employ...

Evolution of water clarity across the Beijing-Tianjin-Hebei region over the past four decades (1984–2024): Driven by hydrological expansion and anthropogenic intervention

Given escalating water scarcity and rapid urbanization, characterizing the long-term evolution of surface water environments across the Beijing-Tianjin-Hebei (BTH) region is vital for coordinated regional development. Using Landsat imagery spanning 1984–2024, this study quantifie...

Exosomes mediate intercellular transmission of Tembusu virus via the NS4A-Rab27a axis

Abstract Accumulating data support the role of exosomes from virus-infected cells (especially RNA viruses) in the selective encapsulation of viral proteins, genomic material, and even whole virions, thereby mediating intercellular communication events and contributing to viral tr...

Nitrogen Sources Reshape Microbial Community Assembly and Interaction Networks to Regulate Straw Decomposition and Carbon Release in Cropland Soils of the North China Plain

The decomposition of crop residue is indispensable for carbon (C) cycling in agricultural ecosystems, and nitrogen (N) application has a pronounced effect on this by regulating the C/N ratio and microbial growth strategy. This study investigated how different inorganic and organi...

Structured Multi-Kernel Heteroscedastic Gaussian Process for Crop Straw-to-Grain Ratio Prediction and Uncertainty Quantification

Crop straw-to-grain ratio (SGR) estimation underpins regional straw resource assessment, yet national inventories rely on fixed coefficients that ignore structured variation across variety, environment, and phenotype. We introduce a Structured Multi-Kernel Heteroscedastic Gaussia...
